.DISCUSSION...
Key message 1: Mostly dry through Tuesday before rain chances return 
middle of next week as a low pressure system approaches out of the 
west.

A backdoor cold front tracks across the GSP forecast area tonight 
into early Saturday morning but will mainly lead to an increase in 
wind speeds, with low-end gusts developing east of the mountains 
late tonight into Saturday morning. Outside of this, dry high 
pressure will be the dominate surface feature through early next 
week as the southern periphery of the high remains extended over the 
Carolinas. This surface ridge will act to shunt the bulk of the 
moisture west and south of the GSP forecast area Sunday through 
Tuesday. However, cannot entirely rule out some brief rain 
developing across the North Carolina mountains and northeast Georgia 
Sunday into Monday per the 12Z NAMNest, 12Z GFS, and 12Z NAM. The 
00Z Euro also shows some rain developing across these zones, but 
mainly Sunday into Sunday night. NBM slight chance PoPs across 
portions of the North Carolina mountains and extreme northeast 
Georgia look to follow the timing and coverage of the Euro for now. 

Better rain chances still look to return by the middle of next week, 
possibly lingering through early Friday, as a low pressure system 
approaches out of the west. However, confidence on exact timing 
remains low with global models still not in great agreement 
regarding the exact track/evolution of this system.


Key message 2: Highs peak today before much cooler highs return this 
weekend into early next week as cold air damming develops. Warmer 
highs return by Thursday as the low pressure system erodes the 
wedge.

High temperatures peak today, climbing into the upper 70s to lower 
80s in the mountain valleys and east of the mountains thanks to an 
upper ridge over the Southeast. Upper ridging gradually breaks down 
this weekend as a shortwave tracks across the Carolinas and northern 
Georgia. Meanwhile, at the surface, high pressure will center itself 
over the Northeast allowing cold air damming to develop Saturday 
into Sunday. The breaking down of the ridge combined with the 
development of cold air damming will allow much cooler high 
temperatures to return for the weekend. Highs should end up near to 
just above normal Saturday and near to just below normal Sunday. 
With no true erosion mechanism to scour out the wedge early next 
week, cold air damming should remain in locked in place. Thus, 
cooler highs should linger through at least Monday but may continue 
into Tuesday. Right now the NBM has above normal high temperatures 
returning by Tuesday but would not be surprised to see highs trend 
lower with future updates as the NBM accounts for the lingering 
wedge. Warmer high temperatures return mid to late week as the 
aforementioned low pressure system tracks across the region and 
finally scours out the wedge.

.AVIATION /18Z FRIDAY THROUGH WEDNESDAY/...
At KCLT and elsewhere: Dry and VFR through the 18Z TAF period. A 
backdoor cold front brings stronger winds late tonight into Saturday 
morning, with low-end gusts most likely for the SC Upstate 
terminals. Wind direction remains N/NE east of the mountains through 
the period. KAVL should see mainly N/NW winds (VRB at times) through 
this afternoon before going calm overnight. Winds at KAVL should 
pick up out of the S/SE after daybreak. Cirrus gradually increase in 
coverage tonight into Saturday, becoming SCT to BKN. This should act 
to limit, or possibly even prohibit, mountain valley fog 
development overnight. 

Outlook: Mostly dry and VFR through Tuesday. Cannot entirely rule 
out restrictions early next week but confidence is low. Otherwise, 
rain and associated restrictions should return middle of next week. 
With cloud cover expected this weekend into much of next week, 
mountain valley fog formation should remain limited.
