This is a live Thursday morning snapshot of local storm-type events across the United States as of the early hours of Thursday, September 10, 2026. Overnight the organized severe pulse from Wednesday’s Slight Risk and Severe Thunderstorm Watch 665 across northern Ohio, northwest Pennsylvania, and western New York has largely expired. The Storm Prediction Center’s Day 1 outlook has settled into a broad Marginal Risk of severe thunderstorms stretching from the southern High Plains to the southern Mid-Atlantic coast. The primary threat language is sporadic damaging wind gusts this afternoon and evening, with isolated large hail possible over south-central Colorado into northeast New Mexico and the Oklahoma–Texas Panhandles.
These remain county- and ZIP-scale thunderstorms. No named tropical cyclone currently threatens U.S. land. Restoration exposure today is residual wind and tree work from last night’s Ohio–Pennsylvania corridor, plus fresh flood and wind potential where the cold front and residual moisture continue to fire cells from the southern Plains eastward. Conditions change fast. Verify with the National Weather Service for the specific county or ZIP before you roll.
What is live this morning
No convective watches are currently valid. Watch 665, the last active severe thunderstorm watch covering the Upper Ohio Valley and Lake Erie counties, has expired. SPC’s 1300 UTC Day 1 Convective Outlook places a Marginal Risk across a long corridor from the southern High Plains through the lower Mississippi Valley and into the Mid-Atlantic. Strong daytime heating is expected south of residual cloud and overnight storms, with temperatures into the 90s to near 100°F over the southern Plains and upper 80s to mid-90s farther east. That buoyancy, coupled with the residual cold front and outflow boundaries, supports thunderstorms that can produce isolated severe gusts.
The Weather Prediction Center’s updated Day 1 Excessive Rainfall Outlook (valid 12Z Thursday–12Z Friday) carries a Slight Risk of rainfall exceeding flash-flood guidance over a focused area from roughly southeast Ohio into central Kentucky and adjacent portions of West Virginia and Indiana. Broader Marginal Risk areas cover parts of the southern Plains, the lower Ohio Valley into the Mid-Atlantic, the Southwest monsoon corridor, and a pocket in the Gulf coastal states.
Hotspot 1 — Residual Ohio–Pennsylvania–western New York wind corridor
Wednesday evening’s Slight Risk and Watch 665 produced a series of severe thunderstorm warnings and local storm reports of tree and power-line damage across northern and central Ohio, northwest Pennsylvania, and adjacent counties. Preliminary LSRs include tree and utility damage near Huron and Hartville, Ohio; Edinboro, Pennsylvania; and Chester, West Virginia, among others. The organized severe threat has moved on, but the restoration desk for those counties is still active: downed trees, service drops, and isolated roof or siding work from 50–70 mph gusts.
Cities and counties still in the aftermath window: Cleveland, Akron, Canton, Mansfield, and surrounding northern Ohio counties; Erie, Crawford, and northwest Pennsylvania; the northern West Virginia panhandle. Stage remaining tree and tarp crews for daylight surveys and carrier documentation.
Hotspot 2 — Southeast Kansas into south-central Missouri flood pulse
Overnight and early this morning, training storms along and south of the cold front have produced locally heavy rainfall across southeast Kansas into portions of western and central Missouri. National Weather Service offices have issued Flood Warnings and Advisories for Allen, Labette, and Montgomery Counties in Kansas (into midday) and adjacent Missouri counties. Radar-estimated amounts of 1–4 inches, with rates of 1–3 inches per hour in stronger cores, have already produced flooding of low-lying roads, creeks, and poor-drainage areas. WPC’s Slight Risk of excessive rainfall for the day is focused farther east into the Ohio Valley, but the Kansas–Missouri corridor remains the live water desk this morning.
Restoration read: extraction and drying work where water entered structures overnight. Photograph damage in daylight, document water lines, and treat any interior water as a same-day priority before the mold clock advances.
Hotspot 3 — Southern Plains to Mid-Atlantic Marginal Risk this afternoon–evening
SPC expects the Marginal Risk corridor to re-fire with daytime heating. The primary hazard is sporadic damaging wind gusts from multicell clusters and short line segments along the residual front and outflow boundaries. Isolated large hail is possible over the higher terrain of south-central Colorado into northeast New Mexico and the Panhandles. Vertical shear is modest overall but sufficient for organized bowing segments farther east where buoyancy is lower but mid-level flow is stronger.
Key population centers under the Marginal Risk umbrella include parts of the Dallas–Fort Worth metroplex, Memphis, Nashville, and the Washington, D.C., corridor, though the risk is scattered rather than continuous. Local Severe Thunderstorm Warnings and Special Weather Statements are the expected mode of action rather than new watches.
Just hit — overnight LSRs
Preliminary Local Storm Reports from the 1200 UTC September 9 – 1159 UTC September 10 window include:
- 1.75-inch hail 8 SE of Colorado City, Huerfano County, Colorado (0600 UTC).
- Wind gusts of 72 mph near Booker, Lipscomb County, Texas; 70 mph SSE of Mayfield, Sumner County, Kansas; 73 mph near Patagonia, Arizona; and multiple 58–78 mph readings in the Arizona–New Mexico border country and western Kansas overnight.
- Numerous tree, limb, and power-line damage reports across northern and central Ohio, northwest Pennsylvania, western West Virginia, and a long swath of eastern Kansas into western Missouri (Baldwin City, Wellington, Clinton, Holden, and surrounding towns).
No tornado reports were received in the preliminary data for this period. All reports remain preliminary and subject to verification.
Pulse table

|---|---|---|---|
| Northern OH / NW PA / western NY | Residual wind / tree / power damage | Watch 665 expired | Aftermath / just-hit |
| SE Kansas / south-central Missouri | Flash flood, training heavy rain | Flood Warnings / Advisories active | Live water desk |
| Southern Plains to Mid-Atlantic | Damaging wind, isolated hail | SPC Marginal Risk | Afternoon–evening re-fire |
| SE Colorado / NE New Mexico / Panhandles | Isolated large hail, strong wind | SPC Marginal (hail-focused) | Afternoon terrain storms |
| Ohio Valley / central KY (WPC) | Excessive rainfall / flash flood | WPC Slight Risk | Day 1 outlook |
| Atlantic / Gulf vs. U.S. mainland | No landfalling tropical cyclone | Quiet | Quiet |
What this means for restoration teams
Wind damage from Wednesday night is already on the books in the Ohio–Pennsylvania corridor—tree removal, roof tarps, and service restoration. Kansas–Missouri flood work is the fresh ticket this morning: extract standing water, document, and start drying before temperatures climb. This afternoon’s Marginal Risk is scattered; the expected mode is isolated warnings rather than a continuous line. Stage for wind and isolated hail in the southern Plains and for additional water if cells train over already-wet ground in the Ohio Valley.
Property owners in just-hit counties should photograph damage in remaining daylight if safe, contact the carrier, and begin extraction the same day if water is inside. Teams working the Kansas–Missouri flood pulse should treat every interior water job as time-sensitive.
What this is not
This is not a regional derecho and not a U.S. mainland hurricane landfall. National Hurricane Center products show no tropical cyclones in the Atlantic basin threatening U.S. land; Tropical Storms Lowell and Norbert remain well offshore in the Pacific. The work today is local: residual wind swaths from Wednesday night, flash-flood pockets in southeast Kansas and western Missouri, and scattered severe gusts under a broad Marginal Risk this afternoon and evening.
Looking ahead
SPC’s Day 2 outlook already carries a Slight Risk of severe thunderstorms for portions of Nebraska into the Upper Midwest on Friday. The cold front will continue to shift east and south, keeping a wet and occasionally strong storm pattern across the Ohio Valley and Mid-Atlantic into the weekend. Watch the next Storm Tracker update rather than assuming today’s Marginal Risk is the end of the corridor.
