AREA FORECAST DISCUSSION
National Weather Service Charleston WV
220 PM EST Fri Feb 21 2025

.SYNOPSIS...
Lingering snow showers dissipate this afternoon. Warming trend
starts Saturday.

&&

.NEAR TERM /THROUGH SATURDAY/...
As of 1220 PM Friday...

Northwesterly flow aloft continues gradually turns more westerly
this afternoon into this evening. Already seeing upstream parcel
trajectories shift south of the Upper Great Lakes for much of the
forecast area, with snow showers largely fading to flurries. Across
the north, snow showers are expected to continue into late this
afternoon/early this evening prior to dissipating. Little, if any
additional snow accumulations are expected.

Initially clearing skies overnight coupled with a dry airmass in
place and broad surface high pressure across much of the eastern
half of the country should yield highly effective radiational
cooling overnight with typical low elevation cold spots and
mountains dipping into the lower teens or upper single digits while
mountain valleys fall into the mid single digits.

Despite the cold start Saturday morning, increasing southwesterly
flow will yield a modest warm-up during the day with highs across
the lower elevations reaching the upper 30s or lower 40s by Saturday
afternoon.

.SHORT TERM /SATURDAY NIGHT THROUGH MONDAY NIGHT/...
As of 220 PM Friday...

Key Points:
* Quiet weather with a moderating trend.

High pressure at the surface and zonal flow aloft transporting
some weak and moisture starved shortwaves across the region. No
precip is expected and temperatures moderate to where even the
higher mountain locations warm above freezing on Monday.

&&

.LONG TERM /TUESDAY THROUGH FRIDAY/...
As of 220 PM Friday...

Key Points:
* Gradual warming trend through midweek.
* Next system late week brings light precipitation.

Pattern amplifies next week as a longwave trough digs in over
the eastern U.S. by the end of the week. A weak shortwave may
bring a few showers Tuesday into Tuesday night but better
chances for rain and then possibly snow arrive late in the
week. This does not look like a major system with generally
light rainfall and snowfall amounts expected at this time and
the gradual warmup expected preceding the system should allow
for a gradual melt of the snow currently on the ground, keeping
river levels in check.

&&

.AVIATION /19Z FRIDAY THROUGH WEDNESDAY/...
As of 1220 PM Friday...


Stratocumulus ceilings dissipate first across the south early this
afternoon and across the north late this afternoon into this
evening. Where clouds remain somewhat thick across the north some
brief dips to IFR visibility are possible in snow showers
through 21Z or so, but otherwise any light snow remains largely
MVFR or better. Skies initially clear overnight with SCT-BKN mid
level clouds moving back in toward daybreak on Saturday.

Winds generally light and favoring a northwesterly/westerly
direction.
