AREA FORECAST DISCUSSION
National Weather Service Charleston WV
122 PM EDT Sat Aug 30 2025

.SYNOPSIS...
Dry weather prevails for most for the end of the weekend into
next week. A few afternoon showers/storms possible Sunday across
the Greenbrier Valley. Better rain chances arrive mid week.

&&

.NEAR TERM /THROUGH SUNDAY/...
As of 120 PM Saturday...

Chamber of Commerce weather is underway across the forecast area
today amid a dome of high pressure slipping down from the Great
Lakes region. This feature will continue to yield mostly dry
weather and unseasonably cooler weather for today. Satellite
imagery at the time of writing depicts some cumulus fields
beginning to develop in southeastern West Virginia and streaming
to the southeast as northwesterly winds push them away from the
forecast area. Otherwise, little to no clouds will be observed
here this afternoon. Daytime heating will encourage temperatures
today to crest in the upper 70s across the lowlands and 60s
along the higher terrain.

Quiet weather stretches into the overnight hours, with another
decent night for radiational cooling noted on forecast soundings
amid clear skies and calm surface winds. Went a touch colder
in the sheltered mountain valleys for Sunday in similar fashion
to lows experienced earlier this morning. River valley fog will
also be present once again for the Tygart Valley, Kanawha, and
Ohio River basins.

Weak shortwave energy trekking into the area on Sunday will impose
some afternoon showers and thunderstorms during peak heating
hours. This is anticipated to occur across our southeastern
zones shortly after 1 PM within towering cumulus and will be
strongly dependent upon diurnal heating, resulting in weakening
activity quickly in the evening. Dry weather will continue to
flourish across our northern half of the forecast area on
Sunday, with slightly warmer afternoon temperatures in the low
80s (lowlands) and low 70s (mountains).

.SHORT TERM /SUNDAY NIGHT THROUGH TUESDAY/...
As of 120 PM Saturday...

Afternoon showers and storms along the southeastern West
Virginia mountains wrap up quickly Sunday evening as high
pressure takes center stage over the Great Lakes region.
Leftover moisture from the day will work in tandem with
overnight radiational cooling to once again encourage river
valley fog to open up the work week.

Otherwise, strong subsidence provided by the nearby high will
yield mostly dry weather to hang about on Monday. This feature
does begin to nudge to the east on Tuesday ahead of a
disturbance that will make its appearance in the long term
forecast period. Increased cloudiness and light showers will
first be noted in the southwestern coalfields during the day
Tuesday before growing in earnest heading into midweek.

Daytime high temperatures will topple back into the low 80s
across the Tri-State area for Monday and Tuesday afternoons, but
remain just under normal readings for this time of year as we
kick off the start of Meteorological Fall.

&&

.LONG TERM /TUESDAY NIGHT THROUGH FRIDAY/...
As of 120 PM Saturday...

After a stretch of dry weather, we should begin to see the
forecast enter a more active state around midweek as a series of
frontal boundaries drop down from Canada. This will force the
dome of high pressure that had taken claim over the Ohio Valley
for the start of the week to now shift off the eastern seaboard.
In response, low level flow will begin to veer out of a
southerly direction and will usher in moisture from the Deep
South. Low end chances for precipitation infiltrate our western
flank of the forecast area Tuesday evening and will spread
eastward and increase in potential heading into midweek.

The first cold front is currently slated to slide across the
country on Thursday, which will impose heightened precipitation
chances before its eventual departure diminishes showers and
embedded thunderstorms late Thursday night into Friday. A
secondary frontal boundary sails down from the northwest late
in the long term period, which will bring cooler temperatures
for the end of next week.

.AVIATION /18Z SATURDAY THROUGH THURSDAY/...
As of 120 PM Saturday...

High pressure over the region will continue to yield little to
no flight restrictions during the daytime hours. However, clear
nighttime skies, coupled with decoupling low level winds, will
encourage river valley fog development late tonight into Sunday
morning, primarily for EKN, PKB, and CRW. Fog erosion takes
place after daybreak and will transform into afternoon cumulus
fields. A few afternoon showers and storms will be possible
shortly after the conclusion of the valid TAF period Sunday
afternoon along the mountains, which could sneak into BKW. Winds
will be light and out of the north through the period.
