The radar
The Charleston,WV radar (KRLX), 113 km from the middle of the area, began a volume at 09:47 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
Roanoke, VA (KRNK), launched 00:00Z, 9.7 hours before the alert went out and 149 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.

Area forecast discussion, Sep 20, 2:28 AM EDT, 3 hours 15 minutes before
Area Forecast Discussion National Weather Service Charleston WV 228 AM EDT Sun Sep 20 2026 .WHAT HAS CHANGED... No significant changes were made from the previous forecast package. && .KEY MESSAGES... 1) Unsettled through mid week amid a cooling trend with improving conditions for the end of the week and the weekend. && .DISCUSSION... KEY MESSAGE 1... Active weather will persist through today and past mid week. A frontal boundary will drape across the region and will meander through Monday while pushing slowly south and finally exiting by mid day Monday. This feature will provide chances for shower and storm activity and where a few storms could be strong to severe which should be isolated in nature. The main threat will be damaging wind. Much of the activity will be confined to the northern parts of our Country Warning Area where higher probabilities of precipitation exist. Another aspect is the area will be under an excessive rainfall outlook and the threat of heavy downpours amid thunderstorm activity will likely cause some instances of flash flooding to flood prone or low lying areas if hit repeatedly. This will be supported by anomalously high PWATs for this time of year. Once the feature exits a low pressure system digging and strengthening across the Great Lakes will come into the region and promote synoptic scale ascent to broaden the unsettled weather across our entire area. For much of Monday and Tuesday and even Wednesday will be under the influence of broad low pressure and chances for shower and thunderstorms. This is especially for Tuesday and Wednesday with high probabilities of precipitation especially during the daytime. This activity along with weak cold air advection will promote temperatures below seasonable starting Tuesday and continuing into the weekend promoting comfortable weather amid drier conditions as strong high pressure builds in for the the end of the work week and for the weekend. && .AVIATION /06Z SUNDAY THROUGH THURSDAY/... A very active morning with shower and thunderstorm activity possible at all sites. With calming flow at the surface some sites may endure fog development such as CRW through the morning. Enough cloud coverage, surface flow and convection should depress much development elsewhere, however there may be times at which a site decouples and fog may form temporarily or stay until 13/14Z. Or the other scenario is that shower activity will lower VIS and it may take a short while before lifting back to VFR. Thereafter, any low stratus will lift a few hours after the fog dissipates and VFR should prevail the rest of the TAF period. FORECAST CONFIDENCE AND ALTERNATE SCENARIOS THROUGH 06Z MONDAY... FORECAST CONFIDENCE: Medium. ALTERNATE SCENARIOS: Restrictions and timing associated with fog will likely vary.Timing of showers/storms may vary from the forecast.
