Severe Thunderstorm Warning 206, NWS Charleston, WV

AREA FORECAST DISCUSSION
National Weather Service Charleston WV
301 PM EDT Fri May 30 2025

.SYNOPSIS...
A potent low brings stout rainfall Friday, with strong storms
possible across the south. Showers/storms linger Saturday. Dry
next week, turning hot by midweek.

&&

.NEAR TERM /THROUGH SATURDAY/...
As of 300 PM Friday...

Tornado and Flood Watches are in effect for low pressure moving
through northeast WV this afternoon, and its cold front
extending southward from it.

A line of showers and strong to severe thunderstorms was moving
into the Tornado Watch area in and near the central and
northern mountains early this afternoon. The warm front
extending east of the low center had essentially made it all the
way to the northern edge of the forecast area, allowing heating
throughout the watch area, with temperatures in the mid to upper
60s and rising.

The Severe Storms Prediction Center and the latest Warn on
Forecast System runs suggests severe probabilities highest in
this area, although the Tornado Watch does extend far enough
south to catch the southern end of the line, which will be first
to exit. The low will exit the northeast corner of the forecast
area by 6 PM, the trailing cold front also exiting east of the
area by then, ending the threat here on the upstream end of the
Watch.

The cerebral precipitation shield wrapping around from the
north side to the west side of the low was mostly in southeast
Ohio, where some area flooding was materializing, and this
shield will move across northern WV and into the Flood Watch
area in northeast WV. The precipitation shield being on the back
side of the low will be enhanced by upslope flow once in and
near the mountains later this afternoon and this evening.

Another short wave trough in the mid/upper-level northwest flow
behind the exiting system is likely to bring another round of
showers overnight into Saturday morning, with showers lingering
in the mountains into Saturday afternoon, again aided by
northwest upslope flow. This additional rainfall should not be
hydrologically significant nor cause an elevated thunderstorm
concern.

The weather will otherwise improve on Saturday, but the
overnight short wave will re-invigorate the surface low off to
the northeast, and gradient will result in gusty winds across
the forecast area through Saturday.

Cold advection behind the system was taking temperatures down
into the 50s behind it, as observed early this afternoon over
the middle Ohio Valley. However, temperatures do not fall much
further there, and lows Saturday morning will be right around
normal. Highs Saturday though will be about ten degrees below
normal, again restricted to the 60s for much of the lowlands.

&&

.SHORT TERM /SATURDAY NIGHT THROUGH MONDAY NIGHT/...
As of 1224 PM Friday...

The upper-level low responsible for bringing unsettled weather
to our region will pull away into eastern Ontario and Quebec
Sunday, and high pressure will slowly build into the Ohio Valley
behind it. Dry weather is expected across our region Sunday,
But lower heights and cold air aloft will keep temperatures
below normal Sunday afternoon. Highs will only be in the upper
60s to lower 70s Sunday.

Upper-level heights will begin to rise Monday as a ridge shifts into
the eastern U.S. This will allow a period of warm and dry weather to
return with high temperatures expected to rebound into the middle to
upper 70s areawide.

&&

.LONG TERM /TUESDAY THROUGH THURSDAY/...
As of 1224 PM Friday...

The upper-level ridge will center itself over the middle Ohio Valley
Tuesday with temperatures expected to soar into the upper 80s. The
ridge will shift farther to the east Wednesday, with the axis
focused over the East Coast. A south-southwesterly flow will
transport warm, muggy air into the middle Ohio Valley with
temperatures reaching the upper 80s to lower 90s and dew points
rising to the middle 60s.

Model variability increases for the late portion of next week, but
models are suggesting the next low pressure system should approach
by next Thursday, which will reintroduce rain chances into the
region through at least next Friday.

&&

.AVIATION /18Z FRIDAY THROUGH WEDNESDAY/...
As of 300 PM Friday...

Low pressure rolling across central WV early this afternoon will
exit east of the mountains by late afternoon.

A strong thunderstorm is likely at EKN 19-20Z just ahead of the
low, and ending at BKW just ahead of its trailing cold front. A
direct hit of a thunderstorm at either of these locations would
bring LIFR conditions, along with wind gusts to 40-50 kts.

North of the low, low MVFR to IFR conditions will continue
through 00Z-01Z CKB and 20-21Z PKB. Behind the low, CRW and HTS
will have VFR to at times MVFR visibility in showers, but
ceilings low MVFR to IFR will continue this afternoon.

Behind the system, MVFR to IFR ceilings will persist tonight and
Saturday morning, with IFR most persistent across te north and
especially in the mountains. Visibility will be mainly VFR, but
MVFR visibility is still possible in showers, most likely in a
round of showers that comes across overnight and into Saturday
morning. Showers will gradually taper off Saturday, lingering
longest in the mountains, and ceilings will lift into a VFR
cumulus field across much of the lowlands Saturday afternoon.

Strengthening cyclonic surface flow will become northwest and
briefly gusty as the low passes this afternoon, but more
persistently gusty at BKW through the period, tonight and
Saturday EKN, and Saturday elsewhere. Cyclonic flow aloft will
become moderate west this afternoon and persist that way into
Saturday afternoon.
