Area forecast discussion, Dec 11, 10:08 AM EST, 21 minutes before
AREA FORECAST DISCUSSION
National Weather Service Charleston WV
1008 AM EST Sat Dec 11 2021

.SYNOPSIS...
Showers/storms are likely across the region today as a cold
front moves through. High pressure then results in dry weather
through midweek, along with a warming trend starting on Monday.

&&

.NEAR TERM /THROUGH TONIGHT/...
As of 1000 AM Saturday...

Tweaked hourly temperatures this morning as several locations
have cooled under the showers. Otherwise, front still progged
to enter CWA shortly....expected to be in Ohio River vcnty
around 18Z, and east of the CWA by late afternoon/early evening.
Temperatures will fall with arrival/passage of the front. Thus
far, stronger winds aloft associated with morning showers/isold
storms have not transfered to the surface. Will see an
additional round of convective showers/isold thunderstorms later
this afternoon with the front, and mainly in the Mid Ohio
Valley region. As with this morning, small possibility a storm
could end up on the strong side if stronger winds aloft can
make it to the surface.

As of 0550 AM Saturday...

Warm temperatures in the lower 70s were noted around Charleston
and Huntington early this morning with the rest of the region
mainly in the 60s. The front that brought warmer trends pulled
north of the area overnight, with the low center currently
tracking across the Mississippi Valley. Thunderstorms/showers
are expected to shift east toward the mountains through the
morning hours, with the main precipitation band remaining along
the western areas of the state until the cold front advances
east. Once the front picks up momentum mid morning, it will take
a fairly quick track toward the mountains. The frontal boundary
should clear the low lands late afternoon with much cooler
temperatures settling in the wake of the low. The mountains will
likely see rain showers change over to snow as the front moves
across this evening as H850 temperatures cool to 7 degrees below
Celsius. Gusty southerly winds today will shift out of the west
behind the front with gusts tapering off overnight.

&&

.SHORT TERM /SUNDAY THROUGH TUESDAY/...
As of 400 AM Saturday...

Following the passage of the cold front, high pressure builds
into the region beginning on Sunday and will slowly slide to the
east throughout the beginning of the new work week. This will
result in dry weather through Tuesday. High temperatures on
Sunday will be seasonable, with a warming trend beginning on
Monday. Above normal temperatures will be in place for both
Monday and Tuesday. Sunday and Monday should feature plenty of
sunshine.

&&

.LONG TERM /TUESDAY NIGHT THROUGH FRIDAY/...
As of 400 AM Saturday...

Return flow on the backside of high pressure will result in a
chance of showers across portions of the area beginning on
Tuesday night into Wednesday morning. This should primarily be
confined to the northern portions of the CWA. Did trim PoPs
slightly from guidance, limiting northern areas to a slight
chance for now. Dry weather will then follow in advance of
another cold front that is set to impact the region in the late
Thursday timeframe. Given a rather impressive upper level ridge
overhead, high temperatures Wednesday and Thursday will be well
above normal, with 60s both days across the lowlands. Cooler
weather then moves in for Friday following the passage of the
front, but temperatures still look to remain above normal.

&&

.AVIATION /15Z SATURDAY THROUGH WEDNESDAY/...
As of 645 AM Friday...

MVFR ceilings are expected through much of the forecast package
with conditions improving west to east late period. A few
thunderstorms are possible in advance of an approaching front
along with heavier showers expected to reduce visibility. Low
level wind shear will impact all TAF sites through the
afternoon, then the jet moves east with conditions improving in
response. Southerly winds gust through the afternoon shifting
west behind the front which clears the eastern mountains between
06-09Z. Gusts are expected to taper off overnight as a ridge
builds from the west.

FORECAST CONFIDENCE AND ALTERNATE SCENARIOS THROUGH 12Z SUNDAY...

FORECAST CONFIDENCE: Medium to High.

ALTERNATE SCENARIOS: Timing for wind shifts may vary. Winds may
gust higher within stronger developing storms. Timing of VFR
conditions across the mountains could come in later if the front
lags on its eastward track.
