.DISCUSSION...
Key message 1: Dry and seasonally warm through Friday, then a strong
cold front brings much cooler temperatures over the weekend. The
risk of any significant weather is low.
Mid/upper anticyclone will gradually slip east from the northwest
Gulf Coast and become elongated across the Deep South and Southeast
through midweek. Height rises and deep insolation from mostly sunny
skies allow temperatures to climb around ten degrees above normal
each afternoon through Friday. Afternoon highs will be in the mid
to upper 80s across the Piedmont and foothills, while the higher
elevations remain in the 70s.
The aforementioned anticyclone will continue to track eastward in
response to a digging shortwave trough that moves southeast from
central Canada. An attendant cold front approaches the region
Friday as a result. However, very little in moisture return
from the Gulf keeps this boundary starved as it pushes across
the CWA Friday without much fanfare. Northwesterly upslope flow
on the backside of the front should develop a few showers along
the immediate Tennessee Border Friday night and early Saturday
morning. A broad continental area of high pressure is expected to
set up shop over the eastern CONUS over the upcoming weekend. In
response, temperatures drop around 20 degrees for afternoon
highs and overnight lows. Overnight lows are forecast to drop
into the 30s across western North Carolina and upper 30s to low
40s across the Upstate and northeast Georgia. There is some frost
potential over the weekend and will have to evaluate throughout
the week. Temperatures will gradually rebound by early next week.

.AVIATION /12Z TUESDAY THROUGH SATURDAY/...
At KCLT and elsewhere: Expect VFR conditions this period outside of
mountain valley and river fog. Mountain valley fog will dissipate by
mid morning but looks to remain away from KAVL. River valley fog is
near KAND and has briefly floated over the terminal. For now, kept
it VFR with a TEMPO MVFR. Light SW wind develops by afternoon, NNW
at KAVL, along with some high based stratocu. Light and variable to
calm wind develops by evening. Mountain valley fog is expected once
again.
Outlook: Expect VFR conditions. The only exception will be the
potential for mtn valley fog overnight/each morning.
