.SYNOPSIS...
A period of tranquil early autumn weather is in store for the
central Appalachians this week as a strong high-pressure system
settles over the region. This dominant weather feature will
ensure dry conditions and mostly sunny skies persist through
the upcoming weekend. Residents can expect comfortable and mild
afternoon temperatures. However, overnight and early morning
hours will be notably cooler, bringing a crisp feel to the air.
This cooling will also lead to the potential for patchy fog
formation in the deeper mountain valleys each morning, which
should dissipate quickly after sunrise.
&&
.NEAR TERM /THROUGH TUESDAY/...
As of 100 PM EDT Monday...
Key Message:
-Dry conditions with chilly overnights and mild afternoons.
Big bubble no trouble. Expect quiet weather courtesy of strong
area of high pressure. Morning fog is possible in the mountain
valleys, otherwise, dry conditions will prevail. Overnight and
early mornings temperatures will be notably cooler with lows in
the 40s...even some readings in the upper 30s for the colder
mountain valleys. On the flip-side, the afternoons will feature
mild conditions with highs ranging from the 60s mountains to the
lower to mid 70s in the foothills and piedmont.
&&
.SHORT TERM /TUESDAY NIGHT THROUGH THURSDAY NIGHT/...
As of 1200 PM EDT Monday...
Key message:
1) Cool and dry weather continues.
Surface high pressure over the Northeast looks to remain in place
through Thursday night. This will generally keep the weather pattern
unchanged through mid week. A subtle warming trend looks likely to
start on Thursday as 850mb temperatures increase roughly 10 degrees
due to the upper level trough currently in place over the eastern
Conus starting to slightly break down mid-week. Outside of this
subtle warming trend back into the mid to upper 70s west of the Blue
Ridge and low 80s east of the Blue Ridge, no precipitation is
expected Wednesday or Thursday.  Lows each morning will generally
fall into the 40s and 50s areawide. Expect to see valley fog each
morning; however, this should dissipate shortly after sunrise each
day.
&&
.LONG TERM /FRIDAY THROUGH SUNDAY/...
As of 1200 PM EDT Monday...
Key message:
1) Dry, but seasonal weather continues.
An upper level trough looks to dig south across the Northeast on
Thursday and Friday this week, which will then be replaced by an
additional surface high pressure by Friday afternoon. This will lead
to continued dry and cool weather as wedging sets up along the
Appalachians in the Mid-Atlantic states. This high pressure looks to
remain quasi-stationary over the Northeast through the middle of the
weekend, which will keep the chances of precipitation out of the
forecast through at least Sunday for the entire region. While enough
dry air through the atmospheric column looks to remain in place
since our PWATs look to remain around 0.75 to 0.85 inches through
the end of the work week and into the weekend. This will
predominantly prevent the wedge pattern from developing a thick
cloud shield over the region. These PWATs should help maintain
mostly clear skies in this wedge pattern, with early morning fog
still likely across river valleys. Overall, expect a generally calm
and quiet period of weather through the weekend as high pressure
remains the dominating feature across the eastern Conus.
Temperatures will generally run in the low 80s east of the Blue
Ridge, and mid to upper 70s west of the Blue Ridge. Lows look
to climb into the low 50s to mid 50s late in the week, but
should warm back up into the mid 50s west of the Blue Ridge and
upper 50s to low 60s by Monday morning lows.

.AVIATION /18Z MONDAY THROUGH SATURDAY/...
As of 100 PM EDT Monday...
Stable weather pattern will lead to little or no weather
concerns this week.
Expecting mostly VFR through the valid 24 hour TAF period. Some
early morning fog is possible in the mountain valleys, but it
should dissipate quickly after sunrise.
Breezy northeast winds this afternoon, with some gusts possible
around 15-20kts. Winds will become light/calm again tonight.
.EXTENDED AVIATION OUTLOOK...
VFR conditions expected through the coming week, outside any
patchy late night/early morning fog.
