AREA FORECAST DISCUSSION
National Weather Service Charleston WV
651 AM EDT Sat Oct 4 2025

.SYNOPSIS...
Tranquil weather prevails into the start of next week courtesy
of high pressure. A cold front slated to arrive on Tuesday
brings the next chance of rain.

&&

.NEAR TERM /THROUGH TONIGHT/...
As of 310 AM Saturday...

River valley fog has been forming across portions of the area and
will continue to expand in coverage prior to sunrise. Fog should
then erode from the area by mid-morning.

Another warm, dry day will materialize as high pressure remains
in control of the Mid- Atlantic region beneath a staunch upper
level ridge. After a cool morning, temperatures will rise above
normal during the day with highs projected to reach mid 60s to
low 80s in the mountains and upper 70s to mid 80s in the
lowlands. Temperatures cool back down into the 40s to 50s
overnight, with calm, clear conditions paving the way for more
fog to develop in the river valleys before sunrise on Sunday.

&&

.SHORT TERM /SUNDAY THROUGH MONDAY NIGHT/...
As of 310 AM Saturday...

Quiet and dry weather is expected to continue through the beginning
of the work week despite a gradual eastward shift of upper level
ridging. Moisture then starts to increase as high pressure recedes
from the area late Monday into Monday night.

Temperatures remain warmer than normal for this time of year with
daily highs expected to be in the 80s in the lowlands and upper 60s
to low 80s in the mountains. Overnight lows should range from near
to above normal during the short term forecast period, with 40s to
50s expected for Sunday night and then 50s to low 60s Monday
night.

&&

.LONG TERM /TUESDAY THROUGH FRIDAY/...
As of 310 AM Saturday...

Precipitation chances spread into the area as moisture continues to
increase ahead of a cold front Tuesday morning, then persist as the
front passes across the area Tuesday night into Wednesday.
Thunderstorms are also likely to occur in conjunction with the
frontal passage, with activity quickly tapering off in its wake.

Drier conditions return with high pressure passing to the north
on Thursday; thereafter, the forecast becomes less certain as
some models remain dry while others suggest the arrival of a
shortwave at the end of the work week.

Temperatures return to normal following the departure of the front
and then remain seasonable through the end of the week.

&&

.AVIATION /12Z SATURDAY THROUGH WEDNESDAY/...
As of 650 AM Saturday...

Ceiling and visibility restrictions will improve once river
valley fog dissipates between 12-14Z, then high pressure
promotes VFR conditions for the rest of the day. While fog may
lead to more sub-VFR conditions late tonight into early Sunday,
coverage may be limited to the deeper river valleys by light
flow aloft.

Winds remain light through the majority of the TAF period.

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

FORECAST CONFIDENCE: Medium to high.

ALTERNATE SCENARIOS: Extent of fog tonight may vary from the
forecast.
