    Storm Updates: West TX Flood & Midwest Marginal — Oct 15

    Tropical: None · Severe: Marginal · Flood: Moderate

    What Changed

    • SPC Day 1 Convective Outlook (0100 UTC / 7:49 PM CDT Thursday, October 15, 2026, valid 160100Z–161200Z) holds a Marginal Risk for parts of southern Indiana into Ohio. A small storm cluster continues across southern IN near the surface trough and warm front; locally damaging wind and a brief tornado remain possible this evening before increasing low-level stability diminishes the threat. No category change from the morning desk; prior Slight Risk has closed.
    • WPC Day 1 Excessive Rainfall Outlook continues the Moderate Risk of excessive rainfall across portions of West Texas (Big Bend / Lower Trans-Pecos / Stockton Plateau into Concho Valley, along and south of I-10 east of the Davis Mountains). High neighborhood probabilities above 70 percent for amounts exceeding 5 inches remain centered in the Moderate area. Category unchanged; strongest overnight signal persists.
    • Residual Tornado Warning and Severe Thunderstorm Warnings for southwestern Indiana and residual Severe Thunderstorm Warning near Fort Worth TX have expired. Flash Flood Warning for Nolan/Taylor Counties TX expired. Flood Watches continue through Friday morning for much of west-central and western Texas. No new convective watches issued. No mesoscale discussions in effect.
    • No tropical storm or hurricane watches or warnings on the U.S. coast or Gulf of America. Atlantic basin remains quiet with no named systems and no formation expected in the next 7 days. Eastern Pacific Hurricane Trudy (intensifying toward Mexico) and Tropical Storm Simon remain offshore Mexico with no U.S. land or Gulf threat. Tropical lane unchanged.
    • Nothing else material shifted since the morning pulse. Severe residual is diminishing as expected; flood Moderate holds as the primary overnight driver.

    Live Status

    As of the Thursday afternoon desk, October 15, 2026 (approximately 9:15 PM PDT / 11:15 PM CDT / 0415Z October 16), the dominant restoration ticket remains the WPC Moderate Risk of excessive rainfall over West Texas. Anomalous October moisture (PWATs near record seasonal values, +2 to +3 standard deviations) and a southward-progressing cold front continue to support heavy convective rainfall this evening into the overnight, with the strongest signal for areal averages of 3–5 inches (local higher, pockets of >5 inches) along and south of I-10 east of the Davis Mountains into the Lower Pecos River basin (Sanderson to north of Del Rio) and northward into the Concho Valley. Flood Watches remain in effect through Friday morning across west-central and western Texas.

    SPC Day 1 holds a Marginal Risk over parts of southern Indiana into Ohio for the remainder of the period. The small storm cluster near the surface trough and warm front continues to support localized strong/damaging gusts and a possible brief tornado this evening. Surface-based buoyancy becomes increasingly scant with time and northeastward extent; the threat is expected to diminish as convection becomes elevated and low-level stability increases later this evening. Residual Tornado and Severe Thunderstorm Warnings that were live earlier have expired. Limited residual severe potential along the outflow-augmented cold front in northwest Texas has also diminished. No mesoscale discussions currently in effect. Overall intensity is waning.

    Hotspots

    West Texas (Big Bend / Stockton Plateau / Lower Pecos / Concho Valley including San Angelo vicinity): Primary Moderate Risk zone. Focused heavy rainfall expected this evening into tonight as the front progresses and nocturnal low-level jet enhances convergence. Flash flooding of creeks, low-water crossings, arroyos, and urban poor-drainage areas is the main concern. HREF/REFS neighborhood probabilities remain high (above 70 percent) for amounts exceeding 5 inches centered within the Moderate area. Areal averages 3–5″ with locally higher possible. Flood Watches continue.

    Southwest Indiana (Knox / Daviess Counties) into southern Ohio: Residual Marginal Risk. Small storm cluster near surface trough/warm front with modest buoyancy and favorable low-level shear supported brief tornado or damaging wind potential this evening. Threat is diminishing as convection elevates and stability increases. Residual Tornado and Severe Thunderstorm Warnings that confirmed radar-indicated rotation and 60 mph gusts have expired. No watches.

    Northwest and residual northern Texas (Fort Worth area, residual northern counties): Residual Severe Thunderstorm Warning for 60 mph wind gusts has expired. Limited organized severe potential along the outflow-augmented cold front has diminished. Preliminary LSRs include tree and roof damage near Millsap and power lines down near Weatherford in Parker County TX this evening. Flood Watches continue through Friday morning across west-central Texas with saturated soils elevating residual flash flood risk for any additional cells.

    Just-Hit

    Overnight and early-morning convection across the southern Plains produced damaging wind reports (gusts 60–75 mph, power lines down, sheet metal and tree damage) in northwest Texas and southwest Oklahoma, plus scattered tree damage in Ohio and West Virginia. Flash flooding occurred or was radar-indicated in multiple northern Texas and southwestern Oklahoma counties this morning, with 1–4+ inches fallen in warned areas. Residual river rises possible on smaller basins. Preliminary tornado report earlier near Fort Stockton TX remains under survey. Residual Tornado and Severe Thunderstorm Warnings confirmed radar-indicated threats over southwestern Indiana and residual Texas this evening; those warnings have expired. No new confirmed tornadoes reported in the latest window. Slight Risk closed overnight and reopened farther northeast before reducing to Marginal this evening.

    Restoration Read

    Primary restoration ticket is water and flash flooding over West Texas under the Moderate ERO, with potential for considerable flash flooding on complex terrain, low-water crossings, arroyos, and urban poor drainage where training occurs under elevated PWATs and frontal convergence. Residual saturated ground and Flood Watches continue across Oklahoma and northern Texas from the prior Moderate axis. Overnight and residual wind damage claims remain possible from earlier 60 mph gusts in northwest Texas and residual Severe Thunderstorm Warnings. The Midwest Marginal supports only isolated tree, power line, or minor structural wind claims as residual storms continue this evening near the warm front; any tornado claims would be brief and localized. No tropical surge or coastal claims. Standard posture: verify county-level Flood Warnings and Watches before deploying; Turn around, don’t drown on flooded roads. Southwest High Wind and Red Flag products are separate non-convective events and do not drive the same restoration response.

    What This Is Not

    This is not a Quiet Pulse. WPC Moderate Risk remains live over West Texas and SPC holds a Marginal Risk over the Midwest with residual threats diminishing. Not a higher-end severe day. Not a tropical threat to the U.S. coast or Gulf. Not a named-storm hub update (no U.S.-threatening cyclone).

    Looking Ahead One Day

    SPC Day 2 outlook carries a Slight Risk of severe thunderstorms over portions of the Mid-Atlantic into southern New England for Friday afternoon and evening (scattered damaging gusts and perhaps a brief tornado accompanying a squall line). WPC Day 2 continues a Moderate Risk of excessive rainfall across portions of West Texas as the front progresses, with the heavy rain threat lingering into early Friday. No tropical development indicated for the U.S. coast or Gulf.

    What Changed

    • SPC Day 1 Convective Outlook (0100 UTC / 7:49 PM CDT Thursday, October 15, 2026, valid 160100Z–161200Z) holds a Marginal Risk for parts of southern Indiana into Ohio. A small storm cluster continues across southern IN near the surface trough and warm front; locally damaging wind and a brief tornado remain possible this evening before increasing low-level stability diminishes the threat. No category change from the prior version of this morning desk; prior Slight Risk has closed.
    • WPC Day 1 Excessive Rainfall Outlook (updated 1601 UTC / 12:01 PM EDT Thursday, October 15, 2026, valid 16Z Thu–12Z Fri) continues the Moderate Risk of excessive rainfall across portions of West Texas (Big Bend / Lower Trans-Pecos / Stockton Plateau into Concho Valley, along and south of I-10 east of the Davis Mountains). High neighborhood probabilities above 70 percent for amounts exceeding 5 inches remain centered in the Moderate area. Slight Risk covers broader southwest Texas into southern Oklahoma. Category unchanged.
    • NWS residual activity: Tornado Warning earlier for east central Knox and central Daviess Counties in southwestern Indiana (radar-indicated). Severe Thunderstorm Warnings residual for portions of northwestern Johnson, southeastern Parker, southwestern Tarrant and northeastern Hood Counties in Texas (near Fort Worth) and for central Knox and Daviess Counties in Indiana. Flash Flood Warning residual for southeastern Nolan and southwestern Taylor Counties in west central Texas. Flood Watches continue through Friday morning for much of west-central and western Texas. No convective watches currently valid (most recent was Watch 685, expired).
    • No tropical storm or hurricane watches or warnings on the U.S. coast or Gulf of America. Atlantic basin remains quiet with no named systems and no formation expected in the next 7 days. Eastern Pacific Hurricane Trudy (intensifying, Hurricane Warnings for Mexican offshore waters) and Tropical Storm Simon remain offshore Mexico with no U.S. land or Gulf threat. Tropical lane unchanged.
    • Severe lane holds Marginal as residual warnings confirm the earlier threat over southwestern Indiana and residual Texas activity near Fort Worth. Flood lane remains Moderate with residual Flash Flood Warning in west central Texas and ongoing Flood Watches. No new watches issued.

    Live Status

    As of the Thursday morning desk update, October 15, 2026 (approximately 8:13 PM PDT / 10:13 PM CDT / 0313Z October 16), two open lanes remain active. The dominant restoration ticket remains the WPC Moderate Risk of excessive rainfall over West Texas. Anomalous October moisture (PWATs near record seasonal values, +2 to +3 standard deviations) and a southward-progressing cold front continue to support heavy convective rainfall, with the strongest signal for areal averages of 3–5 inches (local higher, pockets of >5 inches) along and south of I-10 east of the Davis Mountains into the Lower Pecos River basin (Sanderson to north of Del Rio) and northward into the Concho Valley. Residual Flash Flood Warning activity and active Flood Watches cover west-central and western Texas. A more immediate high-end Slight threat exists in northwest Texas where soils are saturated and FFGs are low.

    SPC Day 1 now holds only a Marginal Risk over parts of southern Indiana into Ohio for the remainder of the period. A small storm cluster has been ongoing across southern IN near the intersection of a surface trough and warm front. As a vigorous mid/upper-level shortwave trough and deepening surface low move across the Great Lakes this evening, the warm front continues northward. Modest buoyancy allows maintenance of convection through parts of OH into the Lower Great Lakes, though surface-based buoyancy becomes increasingly scant. In the short term, locally damaging wind was possible with the strongest storms, and favorable low-level shear supported a brief-tornado threat that is diminishing as convection becomes elevated. Residual Tornado Warning and Severe Thunderstorm Warnings confirmed the threat over southwestern Indiana earlier. North/West Texas has a more limited severe potential along the outflow-augmented cold front with mainly stronger wind gusts possible but organized severe expected to remain limited; residual Severe Thunderstorm Warning near Fort Worth. Overall storm intensity is expected to wane with increasing low-level stability later this evening. No watches are currently valid.

  • Storm Updates: Kansas–Missouri Flood Moderate, Plains–Midwest Marginal — Tuesday, September 15, 2026 (Morning)

    This is a live Tuesday morning snapshot of local storm-type events across the United States as of Tuesday, September 15, 2026. Overnight the organized wind corridor that ran northern Kansas, southern and eastern Nebraska, and western and central Iowa is the just-hit desk. This morning the Storm Prediction Center holds a Marginal Risk of severe thunderstorms from the south-central Plains into parts of the Midwest. The louder national product is flood: the Weather Prediction Center Day 1 Excessive Rainfall Outlook carries a Moderate Risk over portions of northeastern Kansas into northwest Missouri, with a high-end Slight wrapping the Kansas City metro and the I-70 corridor.

    These are county- and ZIP-scale thunderstorms and flash-flood cells, not a mainland hurricane landfall. Restoration exposure today is leftover wind damage from last night plus a new heavy-rain ticket on already-wet Kansas and Missouri ground. Conditions change fast. Verify with the National Weather Service for the specific county or ZIP before you roll.

    What is live this morning

    No Storm Prediction Center convective watch is in effect. Tornado Watch 669, issued late Monday evening, expired at 0500 UTC Tuesday (midnight CDT). Severe Thunderstorm Watch 668 from Monday afternoon is also down. The 1300 UTC Day 1 Convective Outlook (issued 7:28 a.m. CDT) is Marginal only. SPC language: strong to locally severe thunderstorms may occur from the south-central Plains into parts of the Midwest this afternoon and evening, with at least isolated damaging wind gusts possible. A Slight upgrade was considered for eastern Kansas into Missouri if an organized cluster can form, but the 1300 UTC package left probabilities at Marginal.

    WPC’s 0800 UTC Day 1 Excessive Rainfall Outlook is the headline product. A Moderate Risk covers northeastern Kansas into northwest Missouri and clips the far southeast corner of Nebraska along the Missouri River. Guidance centers the heaviest totals just north of Topeka toward St. Joseph, with 2 to 3 inches areal-average and locally 3 to 5 inches possible. Kansas City and the I-70 corridor sit in a high-end Slight. A broader Slight Risk extends south along the cold front on the High Plains and northeast into Midwest counties that already took rain overnight. A separate Slight Risk remains over eastern Arizona and western New Mexico on monsoon-style cells.

    National Hurricane Center: there are no tropical cyclones in the Atlantic. Tropical Depression Fifteen-E and Tropical Depression Norbert are both well out in the Pacific and not a U.S. mainland landfall threat.

    Hotspot 1 — Northeastern Kansas into northwest Missouri (flood)

    This is today’s primary new ticket. WPC coordinated a Moderate Risk with the Topeka and Kansas City weather forecast offices after neighboring counties already saw localized flash flooding earlier in the event. Precipitable-water anomalies of +2 to +3 standard deviations and flash-flood guidance that is already lowered set up 1-inch-per-hour rates after late-afternoon initiation. Best window is late afternoon through tonight as a low-level jet reloads the boundary. Training west-southwest to east-northeast is the mode that fails streets, underpasses, and small creeks first.

    Cities and counties to watch: Topeka and the northeastern Kansas counties north of I-70; St. Joseph and neighboring northwest Missouri counties; the Kansas City metro as a high-end Slight, not the Moderate core; far southeast Nebraska along the river.

    Restoration read: water first. Extraction and drying on a 24-hour clock if cells train over the same ZIP that already took rain Monday night. Do not treat Kansas City as the Moderate core unless WPC or the local office upgrades it later today.

    Hotspot 2 — South-central Plains into the Midwest (Marginal wind)

    A surface cold front will slide slowly south-southeast across the central Plains and mid-Mississippi Valley through this evening and stall late. Dewpoints in the 60s to low 70s sit ahead of it from the southern High Plains to the southern Great Lakes. SPC expects storms to develop roughly 20–23Z along much of the front. Loosely organized clusters with damaging wind are the primary severe concern, more so where heating is stronger on the southern and central Plains. Isolated hail is possible if a marginal supercell can hold from eastern Kansas into Missouri. Population under the 5 percent wind contour includes Wichita, Kansas City, St. Louis, Indianapolis, and Chicago.

    Restoration read: isolated 60 mph-class gusts and trees on service drops, not a regional wind event. Stage in the counties that already have a Severe Thunderstorm Warning, not the entire Marginal contour.

    Hotspot 3 — Southwest scatter and leftover Iowa water

    WPC keeps a Slight Risk of excessive rainfall over eastern Arizona and the western half of New Mexico. Isolated 2 to 3 inch cores on terrain are possible. SPC does not have severe probabilities over the Four Corners this morning; gusty outflow and small hail remain possible but unorganized.

    Iowa is yesterday’s and last night’s water still in the channel. NWS Des Moines had a Flash Flood Warning into 9:00 a.m. CDT this morning for parts of Dallas, Madison, Adair, Cass, Audubon, and Guthrie counties after 1 to 3 inches already on the ground. That is extraction work already on the books, not a new watch.

    Just hit

    Preliminary Storm Prediction Center local storm reports from the 1200 UTC Monday to 1159 UTC Tuesday window show a long wind corridor and almost no hail. One landspout was reported near Arboles, Colorado. No tornado path damage is in the filtered LSR set as of this morning desk.

    Measured wind highlights overnight: 87 mph 3 NE Guide Rock, Webster County, Nebraska; 83 mph 3 SE Smith Center, Smith County, Kansas; 77 mph 4 NNW Amy, Lane County, Kansas; 76 mph 4 N Kendall, Hamilton County, Kansas, and again 2 NNW Beatrice, Gage County, Nebraska; 75 mph 5 ESE Elmwood, Cass County, Nebraska; 74 mph 4 SW McClelland, Pottawattamie County, Iowa; 73 mph 1 N Shelby, Shelby County, Iowa; 71 mph near Richfield, Morton County, Kansas. Tree and power-line damage reports came in from Cass and Lancaster counties in Nebraska, Clarinda and Ames in Iowa, plus scattered tree work in Hinds County, Mississippi, and a power pole down in Tucson, Arizona. That is Monday night’s wind ticket. Today’s new work, if it verifies, is flash flooding on the Kansas–Missouri Moderate Risk.

    What this means for restoration teams

    Last night’s 70–87 mph gusts are roof, siding, gutter, and tree-on-structure work in Webster and Smith counties, the Kansas High Plains, Gage and Cass in Nebraska, and Pottawattamie and Shelby in Iowa. Photograph in daylight if it is safe. Today’s new ticket is water on the Topeka–St. Joseph axis. Heavy rain on already-wet ground is wet drywall and a 24–48 hour mold clock. Iowa southwest counties that sat under the early-morning flash-flood warning are extraction first, not a new severe-wind desk.

    Do not staff the entire SPC Marginal contour as if it were yesterday’s Slight. Yesterday’s Slight verified as a wind line. Today’s organized threat is rainfall rate, not shear.

    What this is not

    This is not a regional derecho and not a U.S. mainland hurricane landfall. Watch 669 is expired. SPC left the Day 1 package at Marginal because an organized cluster is still too uncertain. The work today, if it comes, will be scattered: a flooded intersection north of Topeka or around St. Joseph, a wind swath in an eastern Kansas or Missouri county if a cluster does organize, leftover trees from last night’s Nebraska–Iowa line. That is the local-storm pattern this desk should staff.

    Looking ahead

    SPC Day 2 is Marginal again Wednesday morning near the Great Salt Lake / Salt Lake City vicinity for hail and wind on a shortwave. Day 3 is no severe. WPC will reissue the excessive-rainfall outlook later this morning; treat the Moderate contour as live until that update. The next Storm Tracker desk will catch any watch that fires on the Kansas–Missouri boundary this afternoon.
