This is a live Monday morning snapshot of U.S. local-storm activity as of early Monday, September 21, 2026. The Storm Prediction Center 1300 UTC Day 1 Convective Outlook holds a Marginal Risk of severe thunderstorms from parts of the Southeast into the central Appalachians, and a second Marginal Risk over the Texas South Plains. Isolated damaging wind gusts of 50 to 60 mph are the main threat along the front this afternoon. Isolated large hail and severe gusts are possible later today on the Caprock. No convective watches are currently valid. Severe Thunderstorm Watch 674, last night’s eastern Colorado and extreme western Kansas box, has expired.

These are county-scale thunderstorms, not a U.S. mainland tropical landfall. Tropical Storm Fay is several hundred miles southwest of the Azores and is not a U.S. land threat. Restoration exposure today is leftover tree and roof work from last night’s Ohio Valley and High Plains cells, plus a new wind-damage pulse if the front fires this afternoon from Kentucky into West Virginia and Virginia. Conditions change fast. Verify with the National Weather Service for the specific county or ZIP before you roll.

Overnight into this morning

Radar this morning shows a parade of three mesoscale convective vortices moving east over the Ohio Valley into the central Appalachians, mostly on the cool side of a cold front. That is leftover organization from Sunday night, not a new watch. Local storm reports on the SPC day that closed at 12 UTC Monday include no tornadoes. The hail corridor was eastern Colorado: golf-ball to baseball-size stones around Holyoke, Alvin, Genoa, Boyero, Wild Horse, Kit Carson, Eads, and south of Brandon in Phillips, Yuma, Lincoln, Cheyenne, and Kiowa counties. One social-media measurement near Brandon was 3.10 inches. A spotter windshield was damaged near Wild Horse. A separate 2.00-inch hail report came from Liberty in Union County, Indiana.

Wind reports overnight were the restoration ticket east of the High Plains. Trees and lines came down across Christian, Greene, Jasper, and Lawrence counties in southwest Missouri, including a tree on a house in Pierce City. Illinois reports included a shed roof in Jasper County, 64 mph at Olney-Noble Airport, and power-line damage near Witt, Ramsey, and Noble. Southwestern Ohio logged trees in Kettering, Bellbrook, and Greene County after midnight. After 3 UTC, NWS Charleston territory picked up trees and blocked roads in Vinton and Meigs counties, Ohio, and in Wirt, Calhoun, and Gilmer counties, West Virginia, including more than 1,200 customers without power along Highway 7 north-northeast of Syracuse. Separate tree-down reports ran through Anderson and Laurens counties in South Carolina, Walton County, Georgia, and a string of Alabama, Georgia, and Florida Panhandle counties from Taylor and Iron City to De Funiak Springs and I-10 mile marker 70.

Flash flood warning posts already on this desk overnight covered pieces of Muskingum, Washington, Morgan, and Gallia counties in Ohio and Braxton plus north-central West Virginia. Those warnings were timed to expire in the early morning hours. Treat them as just-hit water, not a new outlook. Confirm county status on weather.gov before you treat a warning as still live.

What is live this morning

No SPC watches are valid as of 1136 UTC Monday. The Day 1 outlook valid 1300 UTC Monday through 1200 UTC Tuesday is Marginal only. The front this afternoon is forecast from northern Mississippi northeast to western Virginia. Dewpoints ahead of it run upper 60s to lower 70s from the lower Mississippi Valley into West Virginia. SPC expects scattered to numerous single-cell and multicell storms after peak heating, with the better flow on the northern edge of the risk — Kentucky, West Virginia, and Virginia. Stronger downdrafts can produce 50 to 60 mph gusts and pockets of wind damage before cells weaken in the early evening.

The Texas South Plains Marginal is a separate, isolated pulse. A front and residual outflow drape the Caprock this afternoon. Guidance supports scattered storms in a moist plume during peak heating, with a couple of stronger cells capable of large hail and severe gusts before they die in the evening.

The Weather Prediction Center Day 1 Excessive Rainfall Outlook page still carried Sunday’s discussion into the 12 UTC Monday valid end, with Slight Risk language over portions of the Midwest and Ohio Valley plus the northern High Plains from the prior period. That is the moisture that already produced last night’s Ohio–West Virginia flood warnings. Use the live WPC graphic and local NWS flash-flood products for today’s water overlay rather than treating Sunday’s Slight as a new box.

Hotspot 1 — Kentucky, West Virginia, Virginia, and the central Appalachians

This is the northern edge of today’s Marginal Risk and the part of the front with slightly stronger flow. Cities and counties to watch: Lexington and eastern Kentucky; Charleston, Huntington, Parkersburg, and the central West Virginia counties that already took trees overnight; western and northern Virginia including the Shenandoah and the Richmond-to-Charlottesville fringe of the outlook line. SPC maps the Marginal from near Greenville, Mississippi, northeast through Kentucky to near Parkersburg, then east toward Elkins, Charlottesville, and Richmond before dropping south through Raleigh and Athens toward Montgomery and Jackson.

Restoration read: wind first, water second. Last night already put trees on roads and lines in Meigs, Wirt, Calhoun, and Gilmer. Another round of 50–60 mph gusts this afternoon is more of the same — roof, siding, service drops — not a regional derecho. If a cell trains on ground that flooded overnight, treat that ZIP as a water job by evening.

Hotspot 2 — Southeast ahead of the front

The same Marginal Risk covers central Mississippi, Alabama, northern Georgia, and the western Carolinas. Instability can peak in the 2000 to 3000 J/kg range from central Mississippi into western North Carolina, but deep-layer shear is weak. Mode is single cells and disorganized multicells. Sunday evening already produced trees in Anderson and Laurens, South Carolina; Monroe and Walton, Georgia; and the Florida–Alabama line. Today is a repeat isolated-wind desk, not a watch.

Restoration read: stage locally if your county is on the warm side of the front. Do not move a regional crew on a Marginal that SPC itself frames as isolated 50–60 mph gusts.

Hotspot 3 — Texas South Plains, plus leftover High Plains hail

The second Marginal sits from near Clovis and Hobbs across the Caprock toward Childress and Big Spring. Isolated large hail and severe gusts later today are the threat. That is not last night’s Colorado supercell corridor. Last night’s work is already on the books in Cheyenne, Kiowa, Lincoln, Yuma, and Phillips counties — baseball hail, damaged glass, and agricultural hits. Do not send the same crew to Lubbock this afternoon and Eads this morning without checking which county actually has a warning now.

Just hit

Sunday afternoon’s High Plains Slight Risk and Watch 674 are closed. The verified story there is large hail, not a tornado. Southwest Missouri trees, Illinois wind, Ohio–West Virginia overnight trees and flash-flood warnings, and scattered Southeast wind reports are the other closed tickets. Tropical Storm Fay is not a U.S. land story.

Pulse table

What this means for restoration teams

Fifty to sixty miles an hour is roof, siding, gutter, and tree-on-structure work. Last night’s Colorado hail is a glass and roof-inspection desk in a handful of High Plains counties, not a regional CAT. Ohio and West Virginia water from overnight flash-flood warnings is extraction and a 24–48 hour mold clock where water entered. Do not staff today’s Marginal as if Watch 674 were still up.

Property owners should photograph damage in daylight if it is safe, call the carrier, and start extraction the same day if water is inside. Turn around, don’t drown on leftover high water in southeast Ohio and north-central West Virginia.

What this is not

This is not a Slight Risk day, not a live watch, and not a U.S. mainland hurricane landfall. The work today, if it verifies, will be scattered: a wind swath through a Kentucky or West Virginia county, a hailer on the Caprock, leftover trees from Sunday night. That is the local-storm pattern this desk should staff.

Looking ahead

The next Day 1 outlook is scheduled by 1630 UTC. SPC Day 2 is also Marginal. Day 3 is currently no severe thunderstorms. Watch the afternoon Storm Tracker update rather than assuming this morning’s Marginal is the last line of the week.
