...18Z Aviation Area Forecast Discussion...

.PREV DISCUSSION... /Issued 645 AM EST Mon Nov 30 2020/

SHORT TERM /Today through Tuesday/...
A short wave will continue crossing the southern Appalachians this
morning...moving northeast to the mid Atlantic states. A cold front
was moving through the forecast area this morning also...currently
pushing east of Athens to Macon with some strong gusts along the
boundary. The front was moving steadily and should be out of east
central GA before sunrise. There have been a few gusts to over 45kts
with the front and some strong gusts in its wake...so a wind
advisory has been issued for this morning. The main upper trough
will deepen over the southeast through tonight...then push eastward.
Wrap around moisture will affect much of north GA through tonight. A
mix of rain and snow can be expected today for much of north GA
(north of Atlanta to Athens)...with precipitation becoming mainly
light snow this evening. Snow accumulations should be around an inch
or less except locally higher amounts in the higher elevations and
on west and northwest facing slopes.

Temperatures should be falling during the day and overnight lows
will range below freezing area wide. Gusty northwest winds will
continue tonight into Tuesday with wind chills in the teens and
20s tonight into Tuesday morning.

LONG TERM /Tuesday Night through Sunday/...
The extended periods begin with the coldest temps we`ve seen so
far this season. Low temps Tuesday night/Wed Morning will be in
the 20s for all of north and central GA. Temps do begin to
rebound Wed as they get up into the 50s across the area and then
into the 50s and 60s Thu. These temps begin to warm ahead of the
next frontal system to approach the area by the end of the work
week.

Extended models are in agreement that there will be an end of the
week system but that is all they agree on. Timing, location,
intensity, and movement of the system are all different from
model to model. The only thing I can say for sure is we will be
seeing some precip Thu or Fri but exactly when where or how much
is out of the question. Will continue with low chance pops for
now and I`m sure they will have a better handle on things over
the next few runs. The one thing to mention though is the GFS has
been the most consistent with this system showing a single low
pressure center that weakens as it moves east.

18Z Update...
OVC CIGS continue to hang all across most sites with MVFR
conditions prevailing across the area. Area of precip has
continued to hang on as it moves in from the west, and could
provide some very light showers over the next few hours mainly
across the north, though some of the metro sites could squeeze
something out. Later tonight, some of these could turn into snow
flurries, though no accumulation expected at any of the TAF sites.
Skies will improve tomorrow. Expect winds to remain gusty,
diminishing a little overnight.

//ATL Confidence...18Z Update...
High confidence all elements.
