The radar

The Charleston,WV radar (KRLX), 129 km from the middle of the area, began a volume at 03:01 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.

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 Jun 27, 8:04 PM EDT, 2 hours 53 minutes earlier. Its key messages:

  • 1) Flood Watch remains in effect through this evening for parts of Kentucky and West Virginia amid a stalled frontal boundary.
  • 2) Turning hot for this upcoming week into the Fourth of July holiday weekend. Heat exposure concerns will be heightened by multiple days of hot temperatures and humidity.

Area Forecast Discussion
National Weather Service Charleston WV
804 PM EDT Sat Jun 27 2026

.WHAT HAS CHANGED...
As of 803 PM...
Allowed the flood watch to expire.

Previous below...
Flooding potential across portions of southeast Ohio and north-
central West Virginia has lessened, prompting cancellation of
the Flood Watch for our northern zones. The Watch currently
remains in effect until 8 PM for northeast Kentucky and
southwestern West Virginia.

&&

.KEY MESSAGES...
- 1) Flood Watch remains in effect through this evening for
  parts of Kentucky and West Virginia amid a stalled frontal
  boundary.

- 2) Turning hot for this upcoming week into the Fourth of July
  holiday weekend. Heat exposure concerns will be heightened by
  multiple days of hot temperatures and humidity.

&&

.DISCUSSION...
KEY MESSAGE 1...

A stalled frontal boundary will once again prompt hydro and
severe concerns across the country today. At the time of
writing, the axis of heaviest rainfall since yesterday to now
has pierced through the heart of Kentucky and aiming
southeastward based on current radar trends, which has spared
our forecast area. A period of moderate rain pressed through
southern West Virginia earlier this morning, with local weather
stations having measured just over an inch of rain as a result.

Based on the latest guidance for today, opted to cancel parts
of the Flood Watch across our northern zones as very little
additional rainfall is expected. Some ensemble members maintain
a swath of heavy rain still to come through this evening across
the Charleston metro area and southward, so will leave the
remaining Watch as is through 8 PM. If model trends continue to
curtail the remaining rainfall projected for the area, the Watch
could be nixed altogether before this evening.

17Z Mesoanalysis shows less of a cap over the CWA than previous
runs, which may allow for isolated development across the north
over the next few hours. Radar does have renewed showers forming
north of I-64 already this afternoon, which may grow slightly
stronger into a thunderstorm. However, the severe risk has
dropped off amid blanketing cloud coverage today. Greatest risk
now resides from Tennessee into the Carolinas.

Showers continue overnight as the front remains planted
overhead, yielding low stratus and locally dense fog heading
into Sunday morning. Concentration of showers and storms will
become focused along the higher terrain and eastward on Sunday
as the frontal boundary begins a sluggish departure northward
for the end of the weekend.

KEY MESSAGE 2...

A dome of high pressure anchoring over the Tennessee and
Mississippi Valleys for the bulk of the upcoming week will
impose multiple days of dangerous heat across the region.
Daytime highs soar into the low to mid 90s for much of the
lowlands beginning on Tuesday, and with the humidity it will
feel closer to 100 degrees or hotter outside. This upcoming heat
wave spanning consecutive days will exacerbate heat exposure
risks as a result. Conduct smart safety protocols during this
period of major heat risk in the Central Appalachians.

&&

.AVIATION /00Z SUNDAY THROUGH THURSDAY/...
Scattered showers, and isolated thunderstorms will continue to
cause occasional IFR flight restrictions across the area for the
remainder of the TAF period. Otherwise, outside of this
activity, widespread MVFR conditions linger, with widespread
IFR/LIFR or worse ceilings and vsbys expected to take hold
across the area, particularly after 06Z to 09Z Sunday in low
stratus and/or fog. Some improvement to widespread MVFR/local
IFR is anticipated after 16Z Sunday, however, isolated to
scattered showers and storms will continue to be possible, with
brief IFR restrictions.

FORECAST CONFIDENCE AND ALTERNATE SCENARIOS THROUGH 00Z MONDAY...

FORECAST CONFIDENCE: Medium.

ALTERNATE SCENARIOS: Timing of rain/storms and associated
restrictions may vary from the forecast. Extent of restrictions
in fog and low stratus tonight may vary from forecast.

Heavy rain may cause ponding of water on roadways and flooding in
low-lying areas.

In hilly terrain there are hundreds of low water crossings which are
potentially dangerous in heavy rain. Do not attempt to travel across
flooded roads. Find alternate routes. It takes only a few inches of
swiftly flowing water to carry vehicles away.
