AREA FORECAST DISCUSSION
National Weather Service Charleston WV
621 AM EST Sun Dec 22 2024

.SYNOPSIS...
Dry through Monday under high pressure, with a milder afternoon
on Monday. The next chance for precipitation is Monday night
into Tuesday.

&&

.NEAR TERM /THROUGH TONIGHT/...
As of 620 AM Sunday...

Stratocumulus continues to erode from the top down. Made some minor
tweaks to sky grids to reflect current satellite with no other
changes needed at this time.

As of 1220 AM Sunday...

Lake enhanced stratocumulus on northwesterly flow, any associated
festive flakes, and impacts to radiational cooling will be the only
forecast problems through this forecast period. Weak northwesterly
flow continues to advect low level moisture beneath a rapidly
drying layer associated with subsidence. Will see these factors
continue to battle through daybreak with patches of clearing
before wholesale improvement during the day today. With a rather
dry airmass in place coupled with light surface winds,
locations that clear will radiate quite effectively and tried to
draw this in where clearing is most likely before daybreak
(Southern Coalfields to Metro Valley). With cloud depth
shrinking due to aforementioned drying aloft, any lingering
flurries should become decreasingly common heading into
daybreak.

Once any lingering stratocumulus clears out today, mostly clear
skies with just a few mid-level clouds to interrupt them are
expected. With a continued dry, still air mass in place tonight,
will see more widespread effective radiational cooling down into the
upper teens/lower 20s on lowland ridges and lower to mid teens in
areas favored for cold air drainage. In the mountain valleys, some
single digits could be observed for Monday morning.

.SHORT TERM /MONDAY THROUGH WEDNESDAY NIGHT/...
As of 100 AM Sunday...

High pressure starts this period with a surface high just off
to our east. This feature will slowly drift away from the area
allowing a clipper to graze us on Tuesday. This system looks to
lose most of its energy as it comes into the area with a warm
front lifting north from a developing low out toward the west.
Surface high pressure makes its way back cutting most of the
moisture out of the warm front. There is only a few hundreths of
an inch of QPF expected across the northern half of the CWA.
Rain will be the regime for most of the area, however snow
showers are possible in the northeast mountains with little to
no accumulations expected. As high pressure builds back in along
with reinforcing upper level ridging most activity will be
stiff armed into the next period with only slight chance PoPs in
the forecast. There will be a warming trend starting Monday and
lasting into the next period.

&&

.LONG TERM /THURSDAY THROUGH SATURDAY/...
As of 100 AM Sunday...

High pressure will have an impact to the area in this period
holding off most activity until the end of the period when
models decide on a few disturbances impacting the area directly
with higher chance PoPs on the board for Saturday and Sunday.
The warming trend will continue for this entire period with
temperatures reaching near 60 degrees across the lowlands by
Friday and Saturday.

.AVIATION /12Z SUNDAY THROUGH THURSDAY/...
As of 620 AM Sunday...

Remnant VFR stratocumulus dissipates this morning with mainly clear
skies through the balance of the forecast period.

Light winds through the period.
