.NEAR TERM /THROUGH TONIGHT/...
-- Changed Discussion --
As of 210 AM EDT Thursday...

Key Message:

1) Warm and more humid today.

High pressure holds over the region today, however a short wave
crosses the Appalachians this afternoon and will trigger isolated
showers and thunderstorms along and north of the Blue Ridge
escarpment. Most of the day we will be battling capping aloft
with minimal shear and instability, so not looking like anything
other than brief summertime showers with isolated thunder. Most
people will only notice an increase in humidity under variable
cloudiness.

Temperatures warm into the mid to upper 80s for most of the
area, with some upper 70s to low 80s for parts of the
mountains. Tonight, temperatures remain warm and in the upper
50s to mid 60s.

Confidence in the near term is high.

.SHORT TERM /FRIDAY THROUGH SUNDAY NIGHT/...
-- Changed Discussion --
As of 120 AM EDT Thursday...

Key Message: Warm and mostly dry weather expected.

A cold front will approach the area with a surface trough draped
over the VA/NC piedmont Friday. The front will bring a few
showers and thunderstorms to southeast West Virginia and far
southwest Virginia late in the afternoon into early evening. The
front will then jump to the surface trough in the piedmont
during the evening. Shower activity will follow the same
pattern, falling part moving over the mountains, shadowing the
foothills and then redevelop in the piedmont. Showers in the
piedmont will track into central North Carolina around midnight.
High pressure will wedge south into the Carolinas on Saturday
and linger into Sunday. No rain is expected this weekend.

Warm southwesterly flow will help Friday`s high temperatures
warm into the 80s across the mountains and lower 90s in the
foothills and piedmont. Cool northeasterly flow will be offset
by dry air and abundant sunshine this weekend. High temperatures
will range from the upper 70s to mid 80s west of the Blue Ridge
to mid to upper 80s east.

Key Points:

Key Messages:

1) Hot and humid next week
2) Showers and thunderstorms possible each afternoon and evening

A ridge of high pressure is expected to drift over the area
Monday and Tuesday then move north of the area Wednesday and
Thursday. This system will bring above normal temperatures and
increase humidity through much of next week. High temperatures
each afternoon will range in the mid to upper 80s across the
mountains and low to mid 90s in the foothills and piedmont. Heat
indices values may be 3F to 6F warmer than the actual surface
temperatures. Diurnal thunderstorms are also possible each
afternoon. Storms will likely start over the mountains in the
afternoon then drift into the foothills and piedmont during the
evening.

.AVIATION /06Z THURSDAY THROUGH MONDAY/...
-- Changed Discussion --
As of 200 AM EDT Thursday...

Mainly VFR expected through the 24 hour valid TAF. Brief period
of IFR fog at LWB possible this morning and again Friday
morning. Otherwise patchy fog possible in the mountain and river
valleys. This afternoon we may see VCSH/VCTS mainly at
KBCB/KROA/KLYH, but chances are too low to include in TAFs.
Light SW winds through the TAF cycle.

Forecast confidence is high.

EXTENDED AVIATION OUTLOOK...

VFR anticipated through Monday. Exceptions...chance of storms
Friday afternoon and evening that may bring sub-VFR, especially
for BLF/LWB and then LYH/DAN as storms reform west of the Blue
Ridge. In addition, morning fog will be possible in mountain and
river valleys.
