AREA FORECAST DISCUSSION
National Weather Service Charleston WV
159 PM EDT Thu Sep 9 2021

.SYNOPSIS...
A few storms possible today as an upper trough swings through.
High pressure for the remainder of the week. A warming trend is
then slated for late this weekend, and into next week.

&&

.NEAR TERM /THROUGH FRIDAY/...
As of 1135 AM Thursday...

Overall, no significant changes necessary to the near term
forecast. Fog/stratus layer has finally scattered out across the
CWA. Still looking at isolated showers and thunderstorms firing
up this afternoon and early evening due to influence of upper
trough and daytime heating. Any storms should dissipate after
sunset. Fog expected to develop again overnight, burning off
late am. Friday looks to be sunny, dry, and cool, under
influence of high pressure and northwesterly flow aloft.

&&

.SHORT TERM /FRIDAY NIGHT THROUGH SUNDAY NIGHT/...
As of 200 PM Thursday...

Upper ridging will move in for the weekend, pushing out the
upper troughing previously over the area. High pressure and
drier air dominate at the surface allowing for a warm and sunny
weekend. Flow at the upper levels will become more zonal toward
the end of the weekend heading into the new work week.

Saturday will be a bit warmer than the end of this week with
high temperatures right around or just below normal, with upper
70s to low 80s across the lowlands and mid 60s to 70s for the
higher elevations. Sunday will be even warmer with temperatures
up into the upper 80s for the lowlands and 70s to low 80s along
the mountains. A warming trend will continue into the beginning
of the new work week.

&&

.LONG TERM /MONDAY THROUGH WEDNESDAY/...
As of 1250 PM Thursday...

High pressure hangs around at the surface to start the long term
period with dry and warm weather continuing into mid week. At
the upper levels, zonal flow continues to hold over the area,
with the models attempting to build upper level ridging back
into the area for Tuesday ahead of an approaching trough.
Temperatures are expected to peak on Tuesday with much of the
area reaching into the upper 80s to lower 90s across the
lowlands.

Chances for showers and thunderstorms will then likely return on
Wednesday as high pressure is pushed out and upper level
troughing approaches the area, moving in by the end of next
week. Current central guidance has temperatures cooling off a
bit by Thursday, closer to around normal.

&&

.AVIATION /18Z THURSDAY THROUGH TUESDAY/...
As of 125 PM Thursday...

Isolated showers and thunderstorms, mainly across north central
WV and the higher terrain, will create brief MVFR/IFR
restrictions, and brief gusty winds through 23Z. Otherwise,
areas outside of showers/storms will remain VFR with light
surface winds. After 06Z Friday, expecting fog to form again,
particularly in favored river valleys and in spots that receive
precipitation today, with local LIFR and VLIFR conditions.
After 14Z Friday expect a return of VFR with light surface
winds.

FORECAST CONFIDENCE AND ALTERNATE SCENARIOS THROUGH 18Z FRIDAY...

FORECAST CONFIDENCE: High.

ALTERNATE SCENARIOS: Greater coverage of showers/storms this
afternoon and evening may occur than currently forecast. Timing
and restrictions associated with fog overnight may vary from
forecast.
