AREA FORECAST DISCUSSION
National Weather Service Charleston WV
1032 PM EDT Wed Aug 13 2025

.SYNOPSIS...
Showers and storms continue tonight, then becoming more diurnal
and confined to the mountains headed into the weekend. Turning
hotter this weekend as high pressure builds.

&&

.NEAR TERM /THROUGH THURSDAY/...
As of 1031 PM Wednesday...

Updated the PoPs once more with some new shoft-range model data.
Still seeing a chain of showers and thunderstorms across the
Huntington Metro Area and just south of Charleston. Most of the
severe threat has waned, but these slower moving storms are
producing rather efficient rainfall rates due to precipitable
water values between 1.6" and 1.9". Rates have been upwards of
3-4"/hour in quite a few locations. This has prompted the
issuance of new flash flood warnings with cells continuing to
backbuild across the warned areas. Locations in and around
Huntington and Barboursville will likely see some flash flooding
issues for the next hour or so.

As of 446 PM Wednesday...

Deviated from the blend of models to go with widespread likely
PoPs across a bulk of the area this afternoon, especially across
the northern half of the forecast area. Showers and thunderstorms
are scattered in nature this afternoon as a cold front pushes
through the area. CAMs show this activity persisting into the
evening with a final push of precipitation moving through
overnight.

As of 225 PM Wednesday...

Active weather is underway this afternoon amid a typical
summer-like pattern, with seasonable temperatures in the mid to
upper 80s, coupled with excess low level moisture and an
encroaching cold front. This set up will continue to encourage
scattered showers and storms throughout the afternoon and
evening, with some growing strong and tall enough with the
capability of producing gusty winds and small hail. Otherwise,
activity today will mainly be monitored for potential of heavy
downpours that could lead to localized water issues.

SPC Mesoanalysis shows current Precipitable Water values
ranging between 1.8 to 2 inches over the area, depicting above
normal conditions for this time of year. One hour FFG values
remain steady around 2 inches or more for the Middle Ohio Valley
and down into the southern coalfields, but a few spots of 1.75
inches are present for locations around northeast WV. Repetitive
showers and storms will also have to be considered with
activity today as precipitation will continuously stream through
the region out ahead of the cold front, analyzed to still be
back in northwest Ohio at the time of writing.

Precipitation gradually wanes after sunset this evening as the
front is anticipated to slide overhead. A plethora of low level
moisture left behind from today`s activity, coupled with calming
winds along the frontal boundary will encourage a combination of
low stratus and river valley fog overnight into Thursday
morning. Skies will be slow to clear out on Thursday as a result
of the front loitering over the area, but should begin to see a
shift in shower and storm coverage and becoming confined along
the mountains where unstable conditions precede the boundary.

Temperatures could be tempered on Thursday by the presence of
the frontal boundary and lingering cloud coverage, but forecast
highs for both today and tomorrow afternoon advertise readings
in the upper 80s to low 90s across the lowlands and 70s along
the higher terrain. Overnight lows tumble down into the 50s and
60s tonight, with near zero dewpoint depressions also pointing
to a decent signature for river valley fog early Thursday
morning.

.SHORT TERM /THURSDAY NIGHT THROUGH SATURDAY/...
As of 225 PM Wednesday...

Shower and storm potential becomes geared toward diurnally
driven opportunities along the mountains for the end of the week
and into the start of the weekend as high pressure strengthens
off the coast of the Carolinas. The cold front at the forefront
of the near term period will slide further southward on Friday
and Saturday, with lowland areas becoming nestled beneath nearby
high pressure. Strengthening onshore flow will yield an uptick
in moisture over the next several days, encouraging the return
of hot and humid weather on Saturday and beyond into the long
term forecast period. All these fixtures will then result in a
repetitive forecast, advertising heat and humidity for our lower
elevations each afternoon with a splash of a few showers and
storms along our mountain zones.

&&

.LONG TERM /SATURDAY NIGHT THROUGH WEDNESDAY/...
As of 225 PM Wednesday...

Robust ridging aloft will encourage a hindrance to strong
disturbances from reaching the Ohio Valley through the course of
the extended period. However, moisture will continue to be
ushered up into the forecast area along southerly low level flow
and will work in tandem with diurnal heating to produce daily
thunderstorm opportunities, especially along our mountain zones
and eastward into the Mid-Atlantic. A few notable ripples of
mid-level energy could slither down along the ridge to
potentially yield additional showers or storms across the north-
central lowlands early next week with the help of a surface cold
front, but some uncertainty remains in regards to its location
and strength.

The heat wave beginning in the short term will continue to
thrive for the late weekend and into the start of next week.
Afternoon temperatures will soar into the low 90s each day
within the lowlands, which coupled with a plethora of low level
moisture will result in heat indices stretching into the low
100s for some starting on Sunday. Certainly something to be
mindful of in the event headlines for heat could be needed.

&&

.AVIATION /03Z THURSDAY THROUGH MONDAY/...
As of 804 PM Wednesday...

Scattered showers and thunderstorms will continue into evening
and overnight hours. An outflow boundary is crossing the area
ahead of the showers and storms with a few gusts up to 30kts
being possible, which prompted some airport warnings.
Convective-allowing models showing a final line of showers/storms
pushing through between ~04z and ~08z. Heavy rain and some
gusty winds are possible with any storms.

Dense river valley fog and mountain low stratus will be in full
force tonight in the wake of recent rainfall. Formation will
spur rather quickly tonight post-rainfall. IFR or lower is in
the forecast for almost all sites, outside of BKW where MVFR
cigs and vsbys with low stratus are expected.

Improvement to VFR will return by ~14z tomorrow with more
chances for showers and thunderstorms in the afternoon and
evening.

Winds will be light and variable to calm overnight with light
N`rly winds taking over on Thursday.
