This is a live Saturday morning snapshot of U.S. local-storm activity as of early Saturday, September 19, 2026. Overnight convection left trees and wires down across the Carolinas and Upstate South Carolina, dumped 1.00–1.50-inch hail on the Utah Wasatch Front and Four Corners, and produced brief tornado or landspout reports near Fruit Heights and Uintah County, Utah. This morning the organized work is water: flash-flood warnings and just-hit rain of 3 to 7.5 inches in southeastern Minnesota and northeastern Iowa, with a Weather Prediction Center Moderate Risk of excessive rainfall still draped over eastern Iowa, northern Illinois, and northern Indiana, plus a second Moderate pocket over southern Montana.

The Storm Prediction Center 1300 UTC Day 1 Convective Outlook holds a Slight Risk of severe thunderstorms across parts of the central Plains, valid 1300Z Saturday through 1200Z Sunday. Summary language: scattered severe wind gusts and large hail this afternoon and evening, focused on Kansas. No convective watches are currently valid. The most recently issued watch was #0669, now expired. There are no tropical cyclones in the Atlantic, eastern Pacific, or central Pacific. A subtropical Atlantic disturbance near the Azores is not a U.S. land threat.

These are county- and ZIP-scale thunderstorms and flash-flood pulses, not a mainland hurricane landfall. Restoration exposure today is interior water where overnight cores trained, then late-day Kansas wind and hail if the Slight Risk verifies. Conditions change fast. Verify with the National Weather Service for the specific county or ZIP before you roll.

What is live this morning

No SPC severe thunderstorm or tornado watch is up at 12:23 UTC Saturday. Friday’s Carolina wind pulse and Utah/Four Corners convection are yesterday’s tickets now sitting as LSRs. What is still live is hydrologic: overnight Flash Flood Warnings for southern Fillmore County, Minnesota; Clayton and Fayette Counties, Iowa; and Dubuque, Jackson, Jo Daviess, and Stephenson Counties on the Iowa–Illinois line. La Crosse and Quad Cities language overnight cited 1–3 inches already down in the Iowa warnings and 3–7.5 inches in the Minnesota flood statements, with a mudslide reported on Highway 76 west of Caledonia and water over the road at Beaver Creek Valley State Park.

Flood Watches remain through Sunday morning across portions of southwest and south-central Michigan, northern Indiana, and northwest Ohio. A separate Flood Watch covers south-central and southeast Montana and Sheridan County, Wyoming, through Sunday afternoon, including burn-scar flash-flood language. Heat Advisories continue into this evening over parts of southeast Kansas and central through southwest Missouri, with heat-index values near 100–105°F — that is a crew-safety overlay on the same Plains corridor that later gets the Slight Risk.

Hotspot 1 — Central Plains Slight Risk (Kansas axis)

This is today’s new severe desk. The 1300Z outlook, issued 7:25 a.m. CDT by Smith/Mead, places a Slight Risk over parts of the central Plains. The 15-percent hail contour covers about 34,700 square miles and 1.33 million people, with larger centers listed as Wichita, Topeka, Lawrence, Salina, and Manhattan. The 15-percent wind contour is a bit larger and also takes in St. Joseph, Missouri. A categorical intensity-level-1 wind overlay (60–75 mph gusts) sits where HREF guidance, precipitable water, and steep low-level lapse rates overlap. A 5-percent wind area fans out as far as Denver, Kansas City, Indianapolis, Cincinnati, and Atlanta — that is the isolated-gust envelope, not the Slight Risk core.

A cold front still runs west-southwest to east-northeast from the central High Plains to the mid-Mississippi Valley and will ease south. Seasonably moist air ahead of it over Kansas, Missouri, and northwestern Oklahoma should become moderately unstable by mid-afternoon. Storms are expected late afternoon into early evening as CIN erodes. Steep 0–3 km lapse rates (8.5–9.5°C/km) favor vigorous cores and evaporative cooling. A few short-lived supercells are possible in the Kansas vicinity given adequate speed and directional shear. Large hail rides with the stronger updrafts. The threat should diminish during the evening.

Farther west, models still build storms near and east of I-25 this afternoon, then grow a loosely organized band — including some supercells — into a linear cluster crossing eastern Colorado into western Kansas. Fifteen-percent wind probabilities were added over eastern Colorado for that mode. Low severe-wind probabilities continue into western Kansas late evening if the cluster holds together.

Cities and counties to watch: Wichita, Hutchinson, Salina, Manhattan, Topeka, Lawrence, and the I-70 / I-35 corridor in Kansas; St. Joseph and the western Missouri fringe; eastern Colorado Front Range and High Plains east of I-25; Amarillo and Enid sit in the broader wind-probability field but are not the Slight Risk bullseye.

Restoration read: stage tarps and glass/roof kits for late afternoon, not after the first warning. Hail on the 15-percent contour is vehicle and shingle work. Wind at 60–75 mph is trees on service drops and isolated roof peel. Do not let the Heat Advisory talk you out of hydration and early staging — that air mass is the same one feeding the storms.

Hotspot 2 — Midwest Moderate excessive rainfall (already hitting)

WPC’s Day 1 Excessive Rainfall Outlook, updated 0844 UTC Saturday and valid 12Z Saturday through 12Z Sunday, maintains a Moderate Risk over portions of the Midwest, particularly eastern Iowa, northern Illinois, and northern Indiana. That is the same corridor that took overnight Flash Flood Warnings. Additional 1–2 inches were still possible in the Iowa–Illinois warnings as of 4:19–5:54 a.m. CDT. Flood Watches through Sunday morning over southwest Michigan, northern Indiana, and northwest Ohio keep the water story open after the current warnings expire.

Southeastern Minnesota is the just-hit core: 4–7.5 inches in Fillmore and Mower Counties with flooding on Highway 16 between Wayland and Peterson, water over County 57 / Minnesota 56, trees washed onto Highway 43 from south Rushford to Bratsberg, and I-90 between mile markers 193 and 204 in the statement footprint. Houston County statements cited 5–7 inches and a mudslide west of Caledonia. Those are extraction and roadway-closure jobs already on the books.

River flooding leftover from earlier in the week still sits on the Saint Marys and Wabash in northeast Indiana and northwest Ohio, with moderate flooding forecast near Decatur and Fort Wayne. That is channel water, not this morning’s flash-flood cores.

Restoration read: Minnesota–northeast Iowa–northwest Illinois is today’s water ticket. Photograph interiors in remaining daylight only if it is safe. The Moderate Risk means another training band can reload the same ZIPs this afternoon. Do not send the Kansas hail crew and the Dubuque water crew as one story.

Hotspot 3 — Southern Montana Moderate flood + High Plains leftover wind

WPC upgraded parts of southern Montana to a Moderate Risk of excessive rainfall. Discussion cited anomalously high moisture, a slow-moving mid-upper low, and deterministic QPF near 3.5 inches with high-end CAM scenarios of localized 7–8 inches if instability verifies. NWS Billings holds a Flood Watch through Sunday afternoon for all of south-central and southeast Montana and Sheridan County, Wyoming, with explicit burn-scar flash-flood language. A separate Flood Watch covers a slice of northeast Montana (Dawson, Garfield, Petroleum, Prairie, Wibaux).

Overnight High Plains wind already verified on the west side of this pattern: 66 mph near Burlington, Colorado; 67 mph southeast of Evansville, Wyoming; 63 mph northwest of Ruleton, Kansas; 69 mph north-northwest of McDonald, Kansas; 64 mph north of Hastings, Nebraska; trees and snapped poles in Cheyenne County, Kansas. Those are Friday night LSRs, not a live watch.

Restoration read: Montana is a flood-and-burn-scar desk, not a wind desk. High Plains wind damage from last night is already on the ground in western Kansas and eastern Colorado. Today’s new wind threat there is the late-day cluster coming off the Front Range.

Just hit

Friday’s Carolinas–Georgia Marginal Risk verified as a wind pulse. Official LSRs include a 69 mph gust at Greensboro (GSO) and 66 mph at Fayetteville (KFAY), plus a long string of trees and wires down from Davie, Guilford, Randolph, Iredell, Rowan, Chatham, Moore, Johnston, Wake, Cumberland, Harnett, Catawba, and Pender Counties in North Carolina into York, Spartanburg, Greenville, Pickens, and Anderson Counties in South Carolina. Shingles and siding damage was reported west-southwest of Statesville. A landspout lofted debris at Lighthouse Point, Broward County, Florida, mid-afternoon Friday. That is a local Florida ticket, not the national headline.

Utah and the Four Corners took the hail and brief-tornado reports: 1.50-inch hail at Kaysville and west of Farmington, Davis County; 1.00-inch hail at Farmington, New Mexico, and Dinosaur / Massadona, Moffat County, Colorado; a tornado report near Fruit Heights, Davis County, from video showing rotation and lofted debris; a landspout report 15 miles east-southeast of Naples, Uintah County. Those cells are down. The work is already there.

What this means for restoration teams

Water is the morning job. Minnesota and the Iowa–Illinois line already have interior and roadway flooding from overnight cores. A Moderate ERO means those same counties can take another round. Kansas is the afternoon job: hail and 60–75 mph wind if the Slight Risk fires on schedule. Montana is a separate flood-and-burn-scar desk with a multi-day watch. Carolina wind and Utah hail are Friday night tickets still waiting on adjusters.

For teams on the Kansas Slight Risk: stage before mid-afternoon local, 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. Heat-index values near 100–105°F on the Missouri–southeast Kansas Advisory are a crew-safety constraint, not a reason to ignore the outlook.

What this is not

This is not a regional derecho and not a U.S. mainland hurricane landfall. No convective watch is up as of mid-morning UTC Saturday. The work today, if it comes, will be scattered: a hail and wind swath through a Kansas county, another flooded intersection where Iowa or northern Illinois cells train, burn-scar runoff in southern Montana, leftover trees in the Carolinas. That is the local-storm pattern this desk should staff.

Looking ahead

SPC Day 2 remains a Slight Risk. WPC Day 2 eases the Midwest and Ohio Valley to a Slight Risk of excessive rainfall as the axis slides east. Flood Watches in Michigan, Indiana, Ohio, and Montana run through Sunday. Watch the next Storm Tracker update rather than assuming the overnight Minnesota warnings were the last water of the weekend.
