The radar

The Charleston,WV radar (KRLX), 40 km from the middle of the area, began a volume at 20:45 UTC, the scan nearest the moment this went out.

The archived warnings, watches and discussions in force at that minute are drawn over the scan, this one among them.

Did it verify

Not verified. The Iowa Environmental Mesonet's Cow found no qualifying storm report inside this flash flood warning while it was in force. That is not proof nothing happened: reports are thin where few people live.

Cow counts a report within 15 km of the polygon while the warning was in force: a tornado for a tornado warning; hail of 1 inch or more, a gust of 58 mph or more or wind damage for a severe thunderstorm warning; a flash flood report for a flash flood warning.

The nearest sounding before it

Cncnati-Daytn, OH (KILN), launched 12:00Z, 8.7 hours before the alert went out and 220 km from the middle of its area. This is the routine balloon launch nearest before it, the air the forecaster had in hand, not a measurement taken for the alert.

What forecasters said that day

The local office's own words before this flash flood warning went out, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.

NWS Charleston, WV wrote its last area forecast discussion before this flash flood warning went out at Sep 23, 2:35 PM EDT, 2 hours 9 minutes earlier. Its key messages:

  • 1.) Continuing to monitor slow-moving showers and thunderstorms churning over the area through this evening for localized flash flooding issues. 2.) Extended stretch of dry weather prevails through next week under the guise of high pressure. Cooler air ushering into the area will yield daytime highs in the 70s and crisp nighttime lows in the 40s and 50s.
Area forecast discussion, Sep 23, 2:35 PM EDT, 2 hours 9 minutes before
Area Forecast Discussion
National Weather Service Charleston WV
235 PM EDT Wed Sep 23 2026

.WHAT HAS CHANGED...
18Z aviation forecast discussion update. Afternoon forecast
package issued with little to no changes from previous cycles.

&&

.KEY MESSAGES...
1.) Continuing to monitor slow-moving showers and thunderstorms
churning over the area through this evening for localized flash
flooding issues.

2.) Extended stretch of dry weather prevails through next week under
the guise of high pressure. Cooler air ushering into the area
will yield daytime highs in the 70s and crisp nighttime lows in
the 40s and 50s.

&&

.DISCUSSION...
KEY MESSAGE 1...

The forecast area remains masked beneath slow moving showers and
embedded thunderstorms this afternoon. These showers, with
cloud tops plateauing around 15-20kft AGL, have little steering
flow aloft to help speed things along and has resulted in very
localized flash flooding thus far today. Rain has fallen over
the same locations for several hours now, primarily across
southwestern and north-central West Virginia, with only meager
observations capturing these higher rainfall accumulations. Some
road closures have been reported throughout the day, and the
risk for flash flooding extends into this evening. Therefore,
will maintain the ongoing Flood Watch through its forecast
expiration of 10 PM tonight.

KEY MESSAGE 2...

Heading into Thursday, precipitation coverage gradually
diminishes from north to south amid building high pressure from
the north and west. Simultaneously, upper level troughing will
shift eastward and a strong coastal low will slither up the
eastern seaboard, which will keep the focus of showers and
storms to the east of the Central Appalachians.

Establishing high pressure and upper level ridging will then set
the stage for an extended period of dry weather from Friday
through at least Monday. Next chance for rain still looks to be
around the middle of next week.

Cooler air advecting into the region beginning Thursday night
could promote patchy frost over the higher ridges of Randolph
and Pocahontas Counties. This was included in this afternoon's
forecast package as a result. Otherwise, expecting Chamber of
Commerce weather through this upcoming weekend into the start of
next week, with daytime highs reaching the 60s/70s, and
overnight low will feel crisp around the 40s/50s.

&&

.AVIATION /18Z WEDNESDAY THROUGH MONDAY/...
Slow moving showers and thunderstorms, scattered in nature,
continue to flourish over our airspace this afternoon. Periodic
MVFR ceilings have been observed at our TAF sites thus far
today, and will remain the trend heading into the evening while
precipitation continues overhead.

Ceilings topple down into IFR late tonight for centralized
terminals of HTS, CRW, and BKW, along with EKN. As high pressure
begins to build in from the north, flight conditions will
gradually improve throughout the day Thursday from north to
south.

Winds will remain out of an east-southeasterly direction
overnight between 5-10 knots into Thursday. Some LLWS was
included at EKN overnight for winds of around 35 knots within
the flight column.
