Storm Updates: Southeast New Mexico Flood Moderate, High Plains Marginal — Thursday, September 24, 2026

This is a live Thursday afternoon snapshot of U.S. local-storm activity as of Thursday, September 24, 2026. The organized desk is water, not a national wind outbreak. The Weather Prediction Center 16Z Day 1 Excessive Rainfall Outlook upgrade holds a Moderate Risk of excessive rainfall across parts of southeast New Mexico. The Storm Prediction Center 1630 UTC Day 1 Convective Outlook holds a Marginal Risk of severe thunderstorms across portions of the eastern Texas Panhandle, western Oklahoma, and western Kansas. No convective watches are in effect as of the 2107 UTC SPC watch page.

These are county-scale thunderstorms and flash-flood cells on saturated soils, not a mainland hurricane landfall. Restoration exposure this afternoon and tonight is interior water and mud where New Mexico cells train, plus isolated wind, hail, and tree work if a High Plains downburst verifies. Conditions change fast. Verify with the National Weather Service for the specific county or ZIP before you roll.

What is live this afternoon

SPC’s 1630 UTC Day 1 outlook, issued 1114 AM CDT Thursday, September 24, 2026, and valid 1630Z Thursday through 1200Z Friday, places a Marginal Risk over about 42,181 square miles and roughly 370,000 people. Named population centers inside the contour include Dodge City, Kansas; Altus, Oklahoma; Pampa, Texas; Woodward, Oklahoma; and Elk City, Oklahoma. The official summary: a couple of marginally severe thunderstorms are possible late this afternoon into the early evening across parts of the southern High Plains. A 2000 UTC outlook update discussed on secondary feeds left the contour unchanged and pointed to Mesoscale Discussion 2327; by 1801 UTC the SPC mesoscale page showed no discussions in effect, with 2326 the most recent archived number.

WPC’s Day 1 excessive-rainfall discussion issued 417 PM EDT Thursday, September 24, 2026, upgraded the existing Slight Risk to a Moderate Risk for portions of southeast New Mexico after coordination with NWS Albuquerque and El Paso. The language cites slow-moving thunderstorms, saturated soils from multiple prior Moderate ERO days, and HREF neighborhood probabilities over 70 percent for both 3 inches of rain and 10-year ARI exceedance over parts of Lincoln, Chaves, and Otero counties. Surrounding Slight and Marginal flood-risk language remains over parts of the Southwest into the southern and central Plains. WPC Mesoscale Precipitation Discussion 1375, issued 238 PM EDT Thursday and valid 1838Z Thursday through 0003Z Friday, flags the Pecos River Valley: flash flooding likely, with 2 to 4 inches possible where cells backbuild near the Sacramento Mountains.

No tornado or severe thunderstorm watches are current. The last issued convective watch on the SPC board is Watch 674, already expired. SPC today’s storm reports (1200 UTC September 24 through 1159 UTC September 25) show one preliminary wind report as of this desk: 60 mph at Memphis in Hall County, Texas, at 1758 UTC, relayed by NWS Lubbock. No hail or tornado reports have posted on that same page yet.

Hotspot 1 — Southeast New Mexico: Lincoln, Chaves, Otero

This is the live flood upgrade. WPC and WFO coordination put the Moderate Risk on the eastern slope of the Sacramento Mountains and the upper Pecos drainage, where soils already sit at very high NASA SPoRT moisture percentiles and flash-flood guidance is low. Cities and counties to watch: Ruidoso and the Lincoln County high country, Roswell and Chaves County, Alamogordo and Otero County, plus adjacent terrain toward the Texas line covered by MPD 1375.

Restoration read: water first. Treat any ZIP that takes a 1- to 2-inch-per-hour core as an extraction job tonight, not a tomorrow morning survey. Photograph only if it is safe. Low-water crossings and arroyos fail before the living room does. Turn around, don’t drown.

Hotspot 2 — Eastern Texas Panhandle, western Oklahoma, western Kansas

This is the SPC Marginal contour. Outlook language from Mosier and Chalmers at 1114 AM CDT Thursday: mid-to-upper 60s dewpoints east of a mid-level moisture plume, afternoon temperatures in the mid to upper 80s, MLCAPE 1500 to 2000 J/kg, weak shear, disorganized storm mode, a few water-loaded downbursts, and a couple of weak supercells possible into Kansas where a weak vorticity maximum moves through. Isolated hail or damaging gusts are the ceiling in the official text. Dodge City, Pampa, Amarillo’s eastern approaches, Altus, Elk City, and Woodward sit inside or on the edge of that language.

Restoration read: isolated wind and hail tickets, not a line. Stage one tarp crew and one extractor, not a CAT convoy. The 60 mph Memphis, Texas, report is the only official LSR on today’s SPC page as of this writing — treat it as a local pulse, not proof the whole contour verified.

Hotspot 3 — Hawaii County under Tropical Storm Nolo; East Coast coastal low is not a named landfall

The National Hurricane Center and Central Pacific Hurricane Center are issuing advisories on Tropical Storm Nolo. As of the Thursday afternoon NHC/CPHC board, Nolo was south of the Big Island with maximum sustained winds near 70 mph, a Tropical Storm Warning in effect for Hawaii County, and forecast language that it could reach hurricane strength later Thursday. That is U.S. land exposure on the Big Island. It is not a continental U.S. landfall.

Tropical Storm Fay is in the central Atlantic, hundreds of miles west-southwest of the Azores, and is not a U.S. land threat on current advisories. Hurricane Polo is off southwestern Mexico. Hurricane Odalys is well west-southwest of Baja. WPC short-range discussion also flags a developing East Coast coastal low for coastal flooding, rip currents, wind gusts, and heavy rain into the weekend. That feature is not a named hurricane making U.S. landfall. Do not staff the Mid-Atlantic as if Fay or Polo were coming ashore.

Just hit

Yesterday’s SPC report page (1200 UTC September 23 through 1159 UTC September 24) is already a ticket list, not today’s new watch: quarter-size hail at New England in Hettinger County, North Dakota, at 2307 UTC; a tree down at Van Wert in Polk County, Georgia, at 2000 UTC; a 58 mph gust 4 SE of Frederick in Tillman County, Oklahoma, at 2158 UTC. Overnight into this morning, NWS Dodge City had a Flash Flood Warning covering parts of Grant, Hamilton, Kearny, Morton, and Stanton counties in southwestern Kansas until 500 AM CDT Thursday after 2 to 3 inches of rain. That Kansas water is yesterday-into-dawn work still on the books.

The Thursday morning Storm Updates already logged the New Mexico–Plains flood slight and Dakotas hail pulse. This afternoon post is the upgrade desk: WPC Moderate on southeast New Mexico, SPC Marginal still on the High Plains, watches still zero.

Pulse table

Region	Main threats	SPC / NWS level	Status this afternoon
SE New Mexico (Lincoln / Chaves / Otero)	Flash flood, training 2–4 in cores	WPC Moderate + MPD 1375	Live flood desk
Eastern TX Panhandle / western OK / western KS	Isolated damaging gusts, isolated hail	SPC Marginal	No watch; late-day cells
SW Kansas overnight counties	Already-fallen 2–3 in rain	Expired FF.W overnight	Aftermath / still wet
Hawaii County	TS wind, surf, heavy rain	Tropical Storm Warning (Nolo)	Live tropical warning
East Coast coastal low	Coastal flood, rip, gusty wind	WPC short-range language	Not a named landfall
CONUS watches	None	No valid SPC watch	Quiet watch board

What this means for restoration teams

Southeast New Mexico is a water night. Saturated soils plus another 2 to 4 inches in a training core is wet drywall, crawlspaces, and a 24-to-48-hour mold clock. High Plains Marginal cells, if they verify, are roof, siding, and isolated tree-on-structure work — staff them as single-ZIP pulses. Hawaii County under Nolo is a separate tropical desk: wind-driven rain, surf, and outages on the Big Island, not a Gulf or Atlantic landfall. Do not mix those three crews in one dispatch board.

For teams near Roswell, Ruidoso, or Alamogordo: stage extractors and pumps before dark, not after the first flash-flood warning. For teams near Pampa, Altus, or Dodge City: one severe-warned cell is the ticket, not the whole outlook contour. Property owners should photograph damage in remaining daylight only if it is safe, call the carrier, and start extraction the same night if water is inside.

What this is not

This is not a regional derecho and not a U.S. mainland hurricane landfall. Fay is mid-ocean. Polo is off Mexico. Odalys is well offshore in the eastern Pacific. Nolo is a Hawaii County warning, which is real U.S. land exposure, but it is not the CONUS headline. The work tonight, if it comes, will be scattered: a flooded arroyo in Lincoln or Chaves County, a downburst roof in the Texas Panhandle or western Oklahoma, leftover Kansas water from last night. That is the local-storm pattern this desk should staff.

Looking ahead

The SPC 1730 UTC Day 2 Convective Outlook issued 1228 PM CDT Thursday, September 24, 2026, valid 1200Z Friday through 1200Z Saturday, carries no severe thunderstorm areas. Summary: severe thunderstorms are not expected Friday. WPC Day 2 excessive rainfall, updated Thursday, holds a Marginal Risk from New Mexico into the Plains and over southeast New England. Day 3 convective language on the SPC homepage still shows a later Marginal window. Watch the next Storm Tracker update rather than assuming today’s Moderate flood contour is the last water line of the week.

Storm Updates: New Mexico Flood Moderate, Utah–Southeast Marginal — Tuesday, September 22, 2026

This is a live Tuesday afternoon snapshot of U.S. local-storm activity as of Tuesday, September 22, 2026. The organized flood desk remains over southern New Mexico. The Storm Prediction Center 2000 UTC Day 1 Convective Outlook still holds two Marginal Risk corridors — much of Utah into adjacent Wyoming and Colorado, and a portion of the Southeast that the 20Z update shifted farther south and east into central Georgia and southern Alabama. No convective watches are currently valid. Restoration exposure this afternoon into tonight is water first in southern New Mexico and far west Texas, isolated severe wind and marginally severe hail on the Utah corridor, locally severe gusts plus leftover flood axes in the Southeast and central Appalachians, and tree/wire work already on the board in Lauderdale County, Alabama.

These are county- and ZIP-scale thunderstorms and flood pulses, not a U.S. mainland hurricane landfall. There is no named tropical cyclone threatening U.S. land this afternoon. Conditions change fast. Verify with the National Weather Service for the specific county or ZIP before you roll. Morning desk: Storm Updates September 22, 2026 (Morning).

What is live this afternoon

SPC’s 2000 UTC Day 1 Convective Outlook (issued 2:56 p.m. CDT Tuesday, September 22, 2026; Halbert/Lyons; valid 222000Z–231200Z) keeps a Marginal Risk for much of Utah into adjacent Wyoming and Colorado, and across a portion of the Southeast. Summary: isolated severe wind gusts expected today in Utah into southwest Wyoming and western Colorado; thunderstorms capable of strong to locally severe damaging gusts also possible across parts of the Southeast. The 20Z update moved the Southeast Marginal farther south and east into central Georgia and southern Alabama, where storms had already developed in an unstable airmass with steep low-level lapse rates.

No convective watches were currently valid as of the SPC watches page update at 15:56:05 UTC Tuesday, September 22, 2026. Most recent watch on the board: 0674. Check spc.noaa.gov/products/watch before you stage.

WPC’s Day 1 Excessive Rainfall Outlook (updated 1553 UTC Tuesday, September 22, 2026; Taylor/Chenard; valid 16Z Tue–12Z Wed) still holds a Moderate Risk across portions of southern New Mexico. WPC notes a potentially significant multi-day flood event over New Mexico and far southwest Texas, with 1–2 inches per hour rain rates this afternoon and training bands tonight. Neighborhood guidance: moderate chance of at least 3 inches (about 40–60 percent) and a low chance of at least 5 inches. Slight Risk axes remain over central to southeast Virginia into South Carolina and West Virginia into southwest Virginia. South Florida stays a WPC Marginal urban-flood desk.

Live warning-scale water this afternoon includes NWS flash-flood warnings for parts of Lincoln/Socorro, Doña Ana/Otero in New Mexico, and Randolph/Webster in West Virginia — already hung as separate Tygart Media warning pulses. NWS also had a flood advisory for west-central Lee County, Alabama (Auburn/Opelika) into late afternoon and a severe thunderstorm warning earlier over Jackson and DeKalb Counties, Alabama.

Hotspot 1 — Southern New Mexico / far west Texas

Still the national flood desk. An upper trough, jet right-entrance dynamics, deep southerly moisture, and precipitable water toward mid/late September record levels support a multi-day event. Afternoon is scattered thunderstorms and flash-flood potential; overnight guidance concentrates a rain shield with heavier cores over southern New Mexico. Sacramento Mountains burn scars remain in the higher-impact language. Flash-flood warnings this afternoon already covered Lincoln, Socorro, Doña Ana, and Otero Counties.

Restoration read: water first, overnight worse than the afternoon pulse. Stage pumps and air movers before the shield organizes. Low-water crossings and burn-scar runoff fail first. Start extraction the same night if water is inside.

Hotspot 2 — Utah into southwest Wyoming and western Colorado

SPC Marginal wind-and-hail corridor is the afternoon convective desk in the West. A potent shortwave over the western Great Basin and a belt of stronger mid-level flow from northern Arizona into central and northern Utah support scattered to numerous storms. Buoyancy stays modest (MLCAPE generally under 1,000 J/kg), but shear and cold mid-levels support organized cells, isolated large hail, and strong gusts off high bases and steep low-level lapse rates. Activity can spill into western Colorado and southwest Wyoming late afternoon into early evening. Larger centers inside the earlier outlook footprint include Salt Lake City, West Valley City, Provo, West Jordan, and Orem.

Restoration read: wind and isolated hail, not a flood CAT. Stage tarps, generators, and tree crews before early evening. Soft-metal roofs and skylights after stronger cores only if it is safe.

Hotspot 3 — Southeast / southern Appalachians

SPC Marginal for the Southeast is a slow-moving cold front into a moist airmass. The 20Z update pulled the risk south and east into central Georgia and southern Alabama, matching storms already on radar. Weak shear keeps the mode multicellular and outflow-dominant; water-loaded downdrafts can still put 50–60 mph gusts on the ground. Today’s preliminary LSRs already show Lauderdale County, Alabama wind damage: power lines down west of Lexington around 1814 UTC, a power pole and lines on a vehicle west of Rogersville around 1835 UTC, and lines down at Lauderdale County High School and the adjacent parking lot around 1856 UTC (NWS Huntsville).

WPC Slight flood axes remain over southeast Virginia into South Carolina and West Virginia into southwest Virginia, where soils are already wet and flash-flood guidance is lower. Randolph and Webster Counties, West Virginia, carried a live flash-flood warning into the evening.

Restoration read: gusty wind and street flooding can share the same ZIP. Alabama tree and wire jobs are already tickets. Charlotte-to-Atlanta language from this morning is not a derecho — treat each county warning as a local pulse.

Just hit

SPC preliminary local storm reports for the 22/1200 UTC–23/1159 UTC window (as of this afternoon hang) show no tornado reports and no hail reports yet. Wind reports on the board are Lauderdale County, Alabama: lines down 3 W Lexington; pole and lines on a vehicle 2 W Rogersville; lines down at Lauderdale County High School in Rogersville. Those are already restoration tickets — trees, wire, and possible vehicle/roof work — not a regional outbreak.

Monday night’s Appalachians–Southeast flash-flood pulse is aftermath. This afternoon’s live water is New Mexico and pockets of West Virginia, plus a Lee County, Alabama flood advisory earlier this afternoon.

Pulse table

Region	Main threats	SPC / WPC / NWS level	Status this afternoon
Southern NM / far west TX	Flash flood, training rain tonight, burn-scar runoff	WPC Moderate + live FFWs	Live flood desk today–Wed
Utah into SW WY / western CO	Severe wind gusts, isolated large hail	SPC Marginal	Afternoon–early evening
SE / central GA / southern AL	Locally severe damaging gusts, trees/wire	SPC Marginal (shifted S/E at 20Z)	Live; AL LSRs already in
SE VA into SC; WV into SW VA	Flash flood / heavy rain	WPC Slight + WV FFWs	Today into tonight
South Florida	Urban flash flood	WPC Marginal	Local
U.S. mainland tropics	No landfalling tropical cyclone	NHC quiet for mainland	Quiet

What this means for restoration teams

Southern New Mexico is the water CAT if the Moderate risk verifies overnight — extraction, drying, and a 24–48 hour mold clock. Utah’s Marginal corridor is wind and isolated hail. Southeast Marginal wind is already producing Lauderdale County tickets; treat Georgia and Alabama warnings as local, not a derecho. West Virginia water is a second flood desk on already-wet ground. Stage New Mexico before the overnight shield. Start extraction the same night if water is inside. Turn around, don’t drown.

What this is not

This is not a regional derecho and not a U.S. mainland hurricane landfall. Post-tropical Fay is open Atlantic near the Azores and is not a U.S. land threat. Hurricane Polo and Tropical Storm Odalys remain eastern Pacific systems and are not mainland landfall threats today. No convective watches are up. Do not invent a named CAT for Restoration Intel off this pulse.

Looking ahead

SPC’s current Day 2 outlook (Wednesday, September 23) is Marginal Risk as of the 1719 UTC issuance (Dean). Day 3 is currently no severe thunderstorms. That does not cancel tonight’s New Mexico flood problem or this evening’s Utah and Southeast Marginal corridors. Watch the next Storm Tracker update rather than assuming the Moderate rainfall risk is the last line of the week.

Storm Updates: Appalachians–Southeast Marginal + Central Appalachians Flood Slight — Monday, September 21, 2026

This is a live Monday afternoon snapshot of U.S. local-storm activity as of Monday, September 21, 2026. The Storm Prediction Center 2000 UTC Day 1 Convective Outlook holds a Marginal Risk of severe thunderstorms from parts of the Southeast into the central Appalachians and over the Texas South Plains. No convective watches are currently valid. The Weather Prediction Center maintains a Slight Risk of excessive rainfall over portions of the central Appalachians. Scattered severe thunderstorm warnings and flash-flood warnings remain active this afternoon across portions of the Tennessee Valley, Carolinas, Alabama, and West Virginia.

These are county- and ZIP-scale thunderstorms and localized heavy-rain pulses, not a mainland hurricane landfall or organized derecho. Restoration exposure this afternoon and evening is wind-driven tree and roof work, isolated hail, and interior water where cells train or flash-flood warnings verify. Conditions change fast. Verify with the National Weather Service for the specific county or ZIP before you roll.

What is live this afternoon

SPC’s Marginal Risk covers the Southeast into the southern and central Appalachians, with isolated damaging wind gusts of 50–60 mph the primary threat. A second Marginal area sits over the Texas South Plains where isolated large hail and severe gusts remain possible later today. Mesoscale Discussion 2323 (issued 1938 UTC) covers the Texas South Plains into the Permian Basin and notes watch issuance is unlikely; strongest storms may briefly produce large hail up to 1.25 inches and marginally severe wind.

WPC’s Day 1 Excessive Rainfall Outlook keeps a Slight Risk over the central Appalachians (expanded earlier to include more of West Virginia and southwest Virginia). Guidance supports 1–3 inches with locally higher amounts where cells train near a backdoor cold front and shortwave energy. Flash Flood Warnings and Flood Warnings remain active or recently expired across portions of West Virginia, Ohio, and adjacent counties from overnight and early-morning convection.

Hotspot 1 — Central Appalachians and Mid-Atlantic fringe (WPC Slight + SPC Marginal)

This is the dual-threat corridor. Scattered thunderstorms continue along and south of a cold front stretching from southern Virginia west-northwest into northern Kentucky and southwestward. Highest coverage expected from southeast Tennessee and northwest Georgia through northern Alabama into central/southern Mississippi and eastern Louisiana, with additional activity into southwest Virginia and West Virginia. Vertical shear is weak; storm mode is largely multicellular and outflow-dominant, but ample moisture (PW values over 2 inches) supports strong to locally severe gusts and flash flooding on saturated soils.

Cities and counties to watch: Charleston, Parkersburg, and surrounding West Virginia counties; southwest Virginia counties including Giles, Mercer, and Summers; portions of eastern Kentucky and southern Ohio; Chattanooga and Knoxville metro fringes in Tennessee; northern Alabama counties including Madison and Marshall.

Restoration read: wind and water both in play. Stage tarps, generators, and tree crews. Flash-flood warnings mean extraction and drying work may already be on the books by evening. Photograph roofs in remaining daylight only if it is safe.

Hotspot 2 — Texas South Plains and northeast Texas

Isolated to widely scattered storms continue near the intersection of a weak surface trough and cold front across the Texas South Plains into the Permian Basin. MD 2323 flags the potential for brief severe storms capable of large hail and marginally severe wind before dissipation this evening. A secondary area of higher thunderstorm coverage is expected over northeast Texas this afternoon and evening, where water-loaded downbursts capable of damaging wind gusts are possible.

Cities and counties to watch: Lubbock, Midland, and surrounding South Plains counties; portions of northeast Texas near the Red River. Local Severe Thunderstorm Warnings have already fired this afternoon in the region.

Restoration read: hail and wind first. Check vehicle and roof damage reports quickly; these are short-lived cells but can produce ticket-scale damage in a single ZIP.

Hotspot 3 — Southeast scatter (Carolinas, Georgia, Alabama, Mississippi)

Ongoing multicell storms continue to produce local Severe Thunderstorm Warnings with 60 mph wind and small to quarter-size hail. Coverage is highest from southeast Tennessee and northwest Georgia through northern Alabama into central/southern Mississippi and eastern Louisiana. Storms are moving relatively slowly or nearly stationary in places, increasing the local flash-flood and wind-damage potential.

Cities and counties to watch: Chattanooga, Huntsville, Birmingham metro areas; portions of the Carolinas and northern Georgia where warnings have been active this afternoon.

Restoration read: scattered wind and tree damage plus isolated water jobs. Treat each warning county as its own ticket rather than a regional event.

Just hit

Overnight and early-morning convection produced Flash Flood Warnings across portions of West Virginia and southeast Ohio, with residual river and stream rises still ongoing in some gauges. Yesterday’s High Plains activity (eastern Colorado into western Kansas) produced large hail reports up to baseball size and is already in the ticket pipeline for those counties. Local wind damage reports from trees and power lines continue to filter in from the Ohio Valley, Illinois, Missouri, Georgia, Alabama, and the Carolinas. No new U.S. mainland tropical cyclone threat is in the National Hurricane Center outlook at this hour.

Pulse table

Region	Main threats	SPC / NWS level	Status this afternoon
Central Appalachians / WV–SW VA	Flash flood, damaging wind, trees	WPC Slight + SPC Marginal	Live warnings + overnight residual
Southeast / TN–AL–GA–MS–Carolinas	Damaging wind, isolated hail, lightning	SPC Marginal + local SVR	Scattered warnings active
Texas South Plains / NE TX	Large hail, severe gusts	SPC Marginal + MD 2323	Isolated cells, watch unlikely
Ohio Valley residual	Flooding from earlier rain	Local Flood Warnings	Aftermath / still in channel
Atlantic / Gulf vs. U.S. mainland	No landfalling tropical cyclone	Quiet on the mainland coast	Quiet

What this means for restoration teams

Wind at 50–60 mph is roof, siding, gutter, and tree-on-structure work. Hail on the South Plains is vehicle and roof impact. Heavy rain on the central Appalachians Slight Risk is wet drywall and a 24–48 hour mold clock where flash flooding verifies. Overnight West Virginia and Ohio water is already inside some buildings.

For teams near active warnings: stage before the next cell arrives, not after the first report. Property owners should photograph damage in daylight if it is safe, call the carrier, and start extraction the same night if water is inside.

What this is not

This is not a regional derecho and not a U.S. mainland hurricane landfall. The work this afternoon and evening, if it verifies, will be scattered: a wind swath through a Tennessee or West Virginia county, a flooded intersection where Appalachian cells train, isolated hail on the South Plains. That is the local-storm pattern this desk should staff.

Looking ahead

Tuesday the front continues to push south and east with another Marginal Risk possible over portions of the Southeast. Residual flooding in the central Appalachians may linger into Tuesday morning. Watch the next Storm Tracker update rather than assuming today’s Marginal and Slight Risk areas are the last line of the week.

Storm Updates: Kansas–Oklahoma Watch 667, Ohio Valley Flood Pulse — Saturday, September 12, 2026

This is a live Saturday afternoon snapshot of local storm-type events across the United States as of Saturday, September 12, 2026. The organized pulse is on the south-central Plains. The Storm Prediction Center holds a Slight Risk of severe thunderstorms across parts of the south-central Plains into the Ozarks, and Severe Thunderstorm Watch 667 is in effect from 3:45 p.m. until 10:00 p.m. CDT for portions of southwest Kansas, Oklahoma, and the Texas Panhandle. Farther east, the Weather Prediction Center keeps a Slight Risk of excessive rainfall over the Ohio Valley and Mid-Atlantic. Tropical Storm Norbert is over the open eastern Pacific and is not a U.S. land threat.

These are county- and ZIP-scale thunderstorms, not a mainland hurricane landfall. Restoration exposure this afternoon and evening is wind-driven roof and siding work, isolated large hail, trees on service drops, and interior water where cells train over already-wet ground in the Ohio Valley and Mid-Atlantic. Conditions change fast. Verify with the National Weather Service for the specific county or ZIP before you roll.

What is live this afternoon

Watch 667 covers southwest Kansas, Oklahoma, and the Texas Panhandle through 10:00 p.m. CDT. Primary threat language from SPC: scattered damaging winds and isolated significant gusts to 80 mph, plus isolated very large hail to 2 inches. Tornado probability in the watch is low. The 2000 UTC Day 1 outlook, issued 3:00 p.m. CDT Saturday, expanded the Slight Risk southwest across parts of western Oklahoma after satellite showed agitated cumulus and isolated initiation along a remnant outflow. Temperatures of 102–104°F south of the wind shift support severe-caliber downdrafts if clusters organize.

Mesoscale Discussion 2286, issued 2:52 p.m. CDT, flagged southern Kansas into northwest Oklahoma as watch-likely before the watch went up. Most probable peak gusts in that discussion were 65–80 mph; most probable peak hail 1.50–2.50 inches. MD 2287 followed on a severe-potential, watch-possible track as storms tried to fill in.

WPC’s Day 1 Excessive Rainfall Outlook, valid 12 UTC Saturday through 12 UTC Sunday, keeps a Slight Risk over the Ohio Valley and Mid-Atlantic. That language is flood first, wind second: 2.0–2.25 inch precipitable water along I-95 from Richmond toward Philadelphia, with a higher-end Slight pocket in the upper Ohio Valley where flash-flood guidance is under 2 inches in northern West Virginia and western Pennsylvania. Central Plains stay Marginal for excessive rain. Florida remains in a localized urban-flood environment on 2.0–2.25 inch precipitable water.

The official SPC Local Storm Report list for the 12 UTC Saturday through 12 UTC Sunday window was still empty as of mid-afternoon, which is expected this early in the convective day. SPC’s same-day report-trend plot on the homepage was already counting preliminary tornado, wind, and hail ticks as storms started to fire. Treat those as unofficial until they land on the LSR page.

Hotspot 1 — Southwest Kansas, Oklahoma, Texas Panhandle

This is the live watch. Storms are expected to increase and intensify near an outflow boundary across Oklahoma and near a front across Kansas and the eastern Texas and Oklahoma Panhandles. SPC notes a narrow corridor of 2,000–3,500 J/kg MLCAPE, 30–40 kt of deep-layer shear, and steep mid-level lapse rates that support isolated 2-inch hail before storms cluster. Higher-based convection in the hot mixed layer favors wind over tornadoes.

Cities and counties to watch: Wichita, Hutchinson, and Emporia in Kansas; Enid, Ponca City, and the Oklahoma City metro fringe; Alva to Chandler along the watch axis; Amarillo and the eastern Texas Panhandle. Neighboring offices: Dodge City, Wichita, Norman, Tulsa, Amarillo.

Restoration read: wind and hail first. Stage tarps, generators, and glass/roof crews before dark. A 75–80 mph gust on a well-mixed 104°F afternoon is a tree-and-roof ticket, not a regional catastrophe. Photograph roofs in remaining daylight only if it is safe.

Hotspot 2 — Ohio Valley and Mid-Atlantic flood pulse

This is the water desk, not the watch desk. WPC holds a Slight Risk of excessive rainfall from the upper Ohio Valley through the Mid-Atlantic. HREF signals in the morning discussion showed moderate-to-high chances of 3-hour and 6-hour flash-flood guidance exceedance in the upper Ohio Valley, and 20–40 percent chances of 3-hour totals over 2 inches from the Richmond area late Saturday into the Delaware Valley and southern New Jersey Saturday night. The Slight Risk was extended north through eastern Pennsylvania, northern New Jersey, and into the New York City metro and lower Long Island for late Saturday night into Sunday.

SPC keeps a Marginal Risk of isolated damaging wind with loosely organized clusters in the upper Ohio Valley this afternoon. That is secondary to the flood overlay.

Cities and counties to watch: Pittsburgh and western Pennsylvania; northern West Virginia; Columbus–Dayton corridor on the wind-marginal fringe; Richmond, Baltimore, Philadelphia, and the I-95 urban core Saturday night.

Restoration read: extraction and drying if cells train. Urban streets, underpasses, and small streams fail first. Do not treat this as the same story as Watch 667. Different hazard, different crew mix.

Hotspot 3 — North Georgia leftover water and Plains scatter

National Weather Service Peachtree City issued multiple Flash Flood Warnings this morning for Cobb, DeKalb, Douglas, Fulton, Carroll, and Paulding counties, including Atlanta, Marietta, Sandy Springs, Douglasville, and Villa Rica. Radar-indicated totals of 1–4 inches were already on the ground in those products, with additional 1–3 inches possible in the warned windows. Some of those warnings expired by mid-afternoon; the water is still in the street and in the buildings. That is already a ticket, not a new watch.

Elsewhere, isolated strong-to-severe cells remain possible on the edges of the Slight Risk into the Ozarks and on the hot High Plains. Florida stays a local urban-flood and lightning desk on deep tropical moisture. A Flash Flood Watch remains up over the Paradise and Hagen burn scar in northeast Oregon and southeast Washington from Saturday afternoon through Sunday evening — debris-flow country, not a CAT event.

Just hit

Friday’s official LSR window (12 UTC September 11 through 12 UTC September 12) is the last closed book. Preliminary reports included a tornado touchdown 7 miles northeast of Artichoke, Minnesota, plus golf-ball hail near Artichoke and Alberta in Stevens County, Minnesota. Wind and hail also hit Tarrant County, Texas (Arlington–Mansfield trees, poles, and up to 1.75-inch hail), Bexar County, Texas (golf-ball hail near Converse and Kirby), and a long tree-down swath through South Carolina, Virginia, and North Carolina. Those are already claims. Today’s new work, if it verifies after 12 UTC Saturday, is Watch 667 wind and hail plus Ohio Valley–Mid-Atlantic water.

Pulse table

Region	Main threats	SPC / NWS level	Status this afternoon
SW Kansas / Oklahoma / TX Panhandle	Damaging wind to 80 mph, isolated 2-inch hail	Slight + Watch 667 to 10 p.m. CDT	Live watch
Ohio Valley / Mid-Atlantic	Flash flood, training heavy rain, isolated wind	WPC Slight excessive rainfall; SPC Marginal wind	Tonight into Sunday morning
North Georgia metro	Urban flash flood leftover from morning warnings	FFW earlier today	Aftermath / still in street
Ozarks / central Plains fringe	Isolated hail and wind	SPC Marginal	Scattered
NE Oregon / SE Washington burn scar	Flash flood / debris flow	Flash Flood Watch through Sunday evening	Local hydrologic
Atlantic / Gulf vs. U.S. mainland	No landfalling tropical cyclone	Quiet on the mainland coast	Quiet (Norbert open EPAC)

What this means for restoration teams

Wind at 65–80 mph is roof, siding, gutter, and tree-on-structure work. Isolated 2-inch hail is broken glass and pitted panels in a narrow swath, not a statewide event. Heavy rain on the Ohio Valley–Mid-Atlantic Slight Risk is wet drywall and a 24–48 hour mold clock. Atlanta-metro water from this morning is already inside some buildings.

For teams in or near Watch 667: stage before 5 p.m. CDT, not after the first warning. Property owners should photograph damage in daylight if it is safe, call the carrier, and start extraction the same night if water is inside. Do not send the same crew to Oklahoma wind and Pittsburgh water without checking which county actually has a warning now.

What this is not

This is not a regional derecho and not a U.S. mainland hurricane landfall. Tropical Storm Norbert is expected to dissipate east-southeast of Hawaii by midweek and is not a CONUS or Hawaii landfall problem on this desk. The work tonight, if it comes, will be scattered: a wind or hail swath through a Kansas or Oklahoma county, a flooded intersection where Ohio Valley or Mid-Atlantic cells train, leftover urban water in metro Atlanta. That is the local-storm pattern this desk should staff.

Looking ahead

Sunday, SPC Day 2 is a Marginal Risk of strong storms with small to marginally severe hail and locally damaging wind from the Ohio Valley to the Northeast. Coverage is uncertain. Monday, Day 3 adds a small Slight Risk across eastern Nebraska into western Iowa. Watch the next Storm Tracker update rather than assuming Watch 667 is the last line of the weekend.

Storm Updates: Southern Plains to Mid-Atlantic Marginal Risk, Ohio Valley Flood Pulse — Thursday, September 10, 2026

This is a live Thursday afternoon snapshot of local storm-type events across the United States as of the afternoon of Thursday, September 10, 2026. The organized severe corridor has broadened and weakened relative to Wednesday’s Slight Risk and Watch 665. The Storm Prediction Center holds a Marginal Risk of severe thunderstorms from the southern High Plains to the southern Mid-Atlantic coast, valid through early Friday morning. The Weather Prediction Center maintains a Slight Risk of excessive rainfall over the upper Ohio Valley into the central Appalachians, with Marginal flood risk farther west and southwest.

These remain county- and ZIP-scale thunderstorms, not a mainland hurricane landfall. Restoration exposure this afternoon and evening is primarily sporadic damaging wind (roof, siding, trees on service drops), isolated large hail on the High Plains, and flash-flood water where cells train over the Ohio Valley–Appalachians corridor. Conditions change fast. Verify with the National Weather Service for the specific county or ZIP before you roll.

What is live this afternoon

No convective watches are currently valid. The most recent watch (Severe Thunderstorm Watch 665) expired overnight. SPC’s 2000 UTC Day 1 outlook (issued 2:40 p.m. CDT) highlights sporadic damaging wind gusts from the southern Plains to the southern Mid-Atlantic this afternoon and evening, plus isolated large hail over south-central Colorado into northeast New Mexico and possibly the Oklahoma and Texas Panhandles. Mesoscale Discussion 2279 (issued ~2:15 p.m. CDT) covers northeast Arkansas into parts of Tennessee and Kentucky: widely scattered storms capable of locally damaging winds, watch unlikely.

WPC’s Day 1 Excessive Rainfall Outlook (updated 1554 UTC) keeps a Slight Risk over the upper Ohio Valley into the central Appalachians—eastern Kentucky and West Virginia remain the core area of highest QPF and training potential. Marginal Risk areas cover parts of the Mid-Atlantic, south-central Plains/Mid-Mississippi Valley, and the Southwest (Arizona–New Mexico into southern California higher terrain).

Hotspot 1 — Northeast Arkansas into Kentucky and Tennessee

MD 2279 flags the live severe potential. Storms developing along and south of a surface boundary in a hot, humid air mass (upper 80s to mid-90s, PWAT near 2 inches, MLCAPE over 1,500 J/kg). Mid-level flow of 25–30 kt may support a few organized multicell clusters. Primary hazard is locally damaging wind gusts (most probable peak 55–70 mph). Coverage of severe is expected to stay limited; no watch is anticipated.

Cities and counties to watch: Jonesboro and northeast Arkansas counties; western and central Kentucky (including areas near the Ohio River); western and middle Tennessee.

Restoration read: Wind first—stage tarps, generators, and tree crews for late afternoon into evening. If a cell trains or produces heavy rain on the WPC slight-risk overlay, treat the same ZIP as a water job by morning.

Hotspot 2 — Upper Ohio Valley and central Appalachians (flood)

WPC Slight Risk of excessive rainfall centers on eastern Kentucky and West Virginia, with a minor eastward expansion into east-central West Virginia on the latest update. Anomalous precipitable water (near 99th percentile), MUCAPE >1,000 J/kg, and potential for training along a front parallel to the mid-level flow support 2–3 inch per hour rates. Soils have been drier of late, but 1-hour flash-flood guidance around 2 inches still leaves room for scattered flash flooding on urban streets, small streams, and low-lying areas.

Some storms are expected to spill east across northern Virginia, northern Maryland, and the Mid-Atlantic I-95 corridor this evening—progressive but still moisture-laden.

Restoration read: Water is the ticket tonight if cells train. Extraction and drying clocks start the same night water enters a structure. Photograph damage in remaining daylight only if safe.

Hotspot 3 — Southern High Plains and residual Kansas–Missouri wind damage

Isolated large hail remains possible over the Raton Mesa vicinity (south-central Colorado into northeast New Mexico) and portions of the Oklahoma/Texas Panhandles under the Marginal Risk. Farther east, residual tree and wire damage from Wednesday evening’s line across parts of Kansas, Missouri, Ohio, and Pennsylvania is already on the books. Local Storm Reports from the overnight period include multiple 60–70+ mph gusts and tree/wire damage across southeast Kansas into west-central Missouri and scattered Ohio counties.

Restoration read: High Plains is today’s new hail/wind cells; Kansas–Missouri–Ohio is yesterday’s wind swath still generating claims. Do not send the same crew to both stories without checking which county actually has active warnings now.

Just hit

Wednesday’s Severe Thunderstorm Watch 665 (northern Ohio, northwest Pennsylvania, western New York) produced multiple wind reports—trees and utility lines down across Erie, Stark, Coshocton, and neighboring counties, plus scattered Kansas and Missouri damage. Those are already tickets. Today’s new work, if it verifies, is the AR–KY–TN wind corridor plus localized flash flooding under the WPC Slight Risk.

Pulse table

Region	Main threats	SPC / NWS level	Status this afternoon
NE AR / KY / TN	Damaging wind, lightning	Marginal + MD 2279	Live cells, watch unlikely
Upper OH Valley / central Appalachians	Flash flood, training heavy rain	WPC Slight excessive rainfall	Tonight into Friday morning
Southern High Plains / Raton Mesa	Isolated large hail, gusty wind	Marginal	Afternoon–evening cells
KS / MO / OH residual	Tree/wire damage from Wednesday	Aftermath	Claims already open
Mid-Atlantic spillover	Heavy rain, localized flood	WPC Marginal	Evening progressive storms
Atlantic / Gulf vs. U.S. mainland	No landfalling hurricane	Quiet on the mainland coast	Quiet

What this means for restoration teams

Marginal-risk wind is still roof, siding, gutter, and tree-on-structure work when a cell organizes. Hail on the High Plains is vehicle and roof dents. The Ohio Valley–Appalachians flood risk is wet drywall and a 24–48 hour mold clock if water enters. Residual Wednesday damage is already generating calls across the Ohio–Pennsylvania corridor and the Kansas–Missouri line.

For teams near the MD 2279 area or the WPC Slight Risk: stage before the densest afternoon heating, not after the first warning. Property owners should photograph damage in daylight if safe, call the carrier, and start extraction the same night if water is inside.

What this is not

This is not a regional derecho and not a U.S. mainland hurricane landfall. The work this afternoon and evening, if it comes, will be scattered: a wind swath through an Arkansas or Kentucky county, a flooded intersection where eastern Kentucky or West Virginia cells train, leftover tree damage from Wednesday’s Ohio–PA activity. That is the local-storm pattern this desk should staff.

Looking ahead

Friday (Day 2) the SPC has a Slight Risk of severe thunderstorms from central Nebraska into the Upper Midwest late afternoon into Friday night—damaging wind, large hail, and a couple of tornadoes possible as an upper shortwave and surface front organize. Later in the period a Marginal Risk appears on Day 3. Watch the next Storm Tracker update rather than assuming today’s Marginal is the last line of the week.
