.SYNOPSIS...
In the wake of a departing cold front, broad surface high pressure
will spread over the region and linger through most of the week.
This will bring fair weather and below normal temperatures.
&&
.NEAR TERM /THROUGH MONDAY/...
As of 720 PM EDT Sunday: Still have some lingering low-end wind
gusts across portions of the forecast area this evening. Should see
winds across the mountains gradually taper off through the next few
hours. Some low clouds are also lingering across the area this
evening but should gradually dissipate in a few hours.
That said, guidance is mixed on whether low clouds hold on or
redevelop overnight. Drier air does work in by evening, so show some
clouds early then dissipate them over most of the area. Dry
conditions expected the rest of the near term. Winds will pick back
up across the Upstate and NE GA becoming gusty overnight. Lows
tonight will end up ~5 to 10 degrees below normal.
Any low clouds that manage to develop will dissipate by Monday
afternoon with sunny and dry conditions expected the rest of the day
with mainly thin cirrus streaming overhead. Highs will end up ~5 to
10 degrees below normal. Gusty NE winds will expand across the NC
foothills and Piedmont early Monday as mixing takes place.

.SHORT TERM /MONDAY NIGHT THROUGH WEDNESDAY/...
As of 1:20 PM EDT Sunday: The short-term forecast picks up at 00z on
Tuesday with upper trofing lifting northward with heights rebounding
over our area. Over the next couple of days, the large-scale upper lvl
pattern will gradually amplify again as broad upper trofing digs down
over Ontario and Quebec and upper ridging amplifies over the central
CONUS. At the sfc, broad high pressure will be in place across the
eastern CONUS as the period begins late Monday. Over the next couple
of days the center of the high will gradually migrate NE, yet it will
continue to control our sfc pattern thru the end of the period late
Wednesday. A weak sfc low tries to develop within the baroclinic zone
just off the SE Coast on Wednesday, however most of the latest guidance
keeps any deeper moisture associated with this system to our east. As
for the sensible fcst, we should remain dry with below-normal tempera-
tures each day.
&&
.LONG TERM /WEDNESDAY NIGHT THROUGH SUNDAY/...
As of 1:10 PM EDT Sunday: The extended fcst picks up at 00z on
Thursday with upper trofing amplifying again over New England
as stout upper ridging persists to our west over the central
CONUS. Over the next few days, most of the long-range guidance
has some amount of upper trofing lingering well to our north
as the upper ridge gradually spreads further east and into our
area by the end of the period. At the sfc, broad high pressure
will still be lingering across most of the eastern CONUS as the
period begins late Wednesday. A weak sfc low will develop within
the baroclinic zone just off the Atlantic Coast and track north-
ward on Thursday, eventually moving out over the north Atlantic
by early Friday. At the same time, another robust sfc high will
migrate SE from Canada and spread another round of dry air back
over the eastern CONUS. Overall, the fcst remains largely unchanged
with dry conditions expected thru the period. Temperatures have
trended a bit warmer, but are still fcst to remain just below
climatology for early September.

.AVIATION /00Z MONDAY THROUGH FRIDAY/...
At KCLT and elsewhere: The trickiest part of the forecast will be
wind speeds/gusts, mainly east of the mountains. Some gusts linger
at KAVL and KAND as of 00Z. Gusts at KAVL should gradually taper off
through the early evening hours but gusts may linger through the TAF
period at KAND. Guidance continues to show the potential for gusts
to return overnight into Monday morning east of the mountains,
potentially lingering through the day Monday before diminishing late
Monday afternoon or early Monday evening. Wind speeds should
generally range from ~5-12 kts with gusts from 16-22 kts east of the
mountains. Wind direction will remain N/NE east of the mountains
through the period. Winds at KAVL should range from 2-6 kts through
the TAF period. Could not rule out a few intermittent low-end gusts
on Monday at KAVL but confidence is too low to mention in the TAF.
Winds will remain NW/NNW through daybreak Monday before gradually
toggling SE by late Monday morning. Otherwise, it will be dry and
VFR through the 00Z TAF period outside of the mountain valleys,
where fog and/or low stratus may develop.
Outlook: VFR and dry through much of next week. Fog and/or low
stratus is possible each morning, especially in the mountain valleys.
