.SYNOPSIS...
Warmer temperatures expected Thursday even as rain chances continue.
Fair afternoon skies and exceptionally warm weather end the week. A
cold front brings shower and thunderstorm chances on Sunday, with
drier and cooler conditions through the middle of next week.

.NEAR TERM /THROUGH THURSDAY/...
As of 1000 PM EDT Wednesday: Convection has blossomed over the last
two hours, with scattered showers and thunderstorms noted across the
western Carolinas. Increased PoPs over the next few hours where it`s
currently raining per the latest KGSP radar mosaic loops. Luckily,
storms have remained below severe limits this evening but we have
seen a handful of strong storms that were worth of Special Weather
Statements. This trend should continue for at least the next few
hours as a warm front lifts north over the forecast area. Showers
may linger along the Blue Ridge Escarpment through the overnight
hours.

Tonight, any improvement in low stratus will be wiped out.
Despite the surface low moving far enough offshore that it won`t
really be in position to actively sustain the wedge any longer,
there won`t be a mechanism to erode it; rather, there will be the
usual nighttime inversion and moist southeasterly flow keeping
the boundary layer saturated...which all but guarantees the murky
conditions will persist through the night.  Lows will struggle
to fall below the upper 50s or lower 60s.  The daylight hours on
Thursday will feature slow clearing...as daytime heating very slowly
mixes the residual wedge.  Temps for tomorrow are tricky...since
the temperature trend will be highly dependent on how quickly
the wedge scatters out.  The NBM and a consensus of the 12z CAMs
are forecasting highs in the upper 70s or even lower 80s...but
think actual highs could wind up cooler since these models may be
clearing out the wedge unrealistically fast.

.SHORT TERM /THURSDAY NIGHT THROUGH SATURDAY/...
As of 150 PM Wed: Upper ridge starts out over the area then slowly
moves eastward as a trough digs into the Midwest. The moist upslope/
upglide weakens Thursday evening bringing an end to any showers.
Despite the ridge in place Friday, there looks to be enough moisture
and weak instability for isolated to scattered showers across the
mountains during the afternoon and early evening as a front moves
south toward the area but stalls just to our north. An isolated
ridge top shower can`t be ruled out Saturday afternoon, but overall
chance of precip is low with less in the way of moisture and
instability as the front moves north away from the area and a
surface ridge reasserts itself. Thicknesses and heights remain high
under the ridge. This puts record highs in jeopardy both days. Lows
will be around 20 degrees above normal.

&&

.LONG TERM /SATURDAY NIGHT THROUGH WEDNESDAY/...
As of 210 PM Wed: The upper trough mentioned at the end of the short
range moves east and pushes a cold front into the area Sunday. There
will be plenty of forcing and shear, along with high PW values,
associated with the front. There will be some instability, but the
amount is uncertain. Therefore, there is a low severe and excessive
rainfall threat which we`ll keep an eye on as the event approaches.
A wave forms along the front slowing its eastward progression
Monday. This will keep a chance of lingering showers across the
area, but any severe and flood threat will have moved eastward.

A weak secondary front/clipper type low may cross the area Tuesday,
but the guidance keeps shifting from low chance precip to dry. Have
kept the forecast dry for now. Dry and cooler high pressure moves in
Wednesday.

Temperatures are cooler but still above normal Sunday and falling to
near normal Monday. Temps drip below normal for Tuesday and
Wednesday. This brings a frost concern for the non-mountain areas of
the Upstate and NE GA and the NC southern foothills and Piedmont,
where the growing season has started.

.AVIATION /02Z THURSDAY THROUGH MONDAY/...
At KCLT and elsewhere: Scattered showers and thunderstorms are
tracking across the western Carolinas as of 0200Z. Activity is
expected to linger for at least the next few hours. -SHRA may linger
along the Escarpment, near KAVL and KHKY, through the overnight
hours. KGSP AND KGMU may see -SHRA redevelop overnight into Thursday
morning so have PROB30s at these terminals. Cigs and vsbys are
expected to gradually lower to LIFR to IFR levels by daybreak, with
VLIFR cigs possibly developing everywhere except KAND. Vsbys should
gradually improve after daybreak, returning to VFR by late
morning/early afternoon Thursday. Cigs will be slow to improve
Thursday, with MVFR returning by the early to mid afternoon hours
and VFR returning by late afternoon/early evening. Rain chances
should linger at KAVL through at least the overnight hours so have a
PROB30 for -SHRA at the terminal from 06Z-12Z Thursday. Went with
VCSH from 12Z-15Z as activity may linger near the terminal after
daybreak. KHKY, KGSP, and KGMU may see -SHRA chances return
overnight into Thursday morning so went with PROB30s at these
terminals as well. Winds will generally be S`ly at KAVL through the
TAF period. Winds elsewhere will gradually turn S`ly this evening
into tonight, remaining at this direction through the end of the TAF
period. Low-end wind gusts will be possible through early Thursday
evening.

Outlook: IFR to MVFR cigs may return again late Thursday night into
Friday morning. Drier conditions return Thursday night into Saturday
night before another cold front brings shower and thunderstorm
chances, and associated flight restrictions, back on Sunday.
