SHORT TERM /Tonight through Friday Night/...

Surface analysis and GOES-EAST Satellite imagery show an intensifying
low pressure system moving across the Ohio River Valley, with
redevelopment on the lee side of the Appalachians along the
baroclinic coastal zone in the Carolina already well underway. In
the mid-to upper-level of the atmosphere, dry sinking air has
already moved over the region, pushing out the moisture conveyor
belt that has been over the region for the past few days prompting
previous Flash Flood Watches. Now as a dry, cold airmass moves in
this evening, combined with clearing skies and high temperatures
that are already 15-20 degrees below normal. Most of the forecast
area will see temperatures at or below freezing for the first time
this year. See the ongoing Freeze Warning for tonight or more
details. Winds tonight will pick up with gusts as high as 10 to 20
knots tonight across most of our area, but areas of patchy fog
and frost may develop in places where the winds remain lighter.

Tomorrow, surface high pressure returns to the area bringing mostly
sunny skies which will help rebound temperatures to only 10 degrees
below normal with highs in the 50s. With lighter winds tomorrow
night, expect more widespread areas of patchy fog to develop.

LONG TERM /Saturday through Thursday/...

A dry and "seasonal" preiod is in store for north and central
Georgia heading into the Thanksgiving holiday. A weak system within
the broader longwave pattern will approach the area Sunday night
into Monday but aside from increasing clouds, little if any
measurable precipitation is expected at this time. Temperatures
will be near normal for mid November.

AVIATION...
00Z Update...
IFR ceilings, which have been slow to lift, have largely
transitioned to MVFR range this evening. Expect MVFR ceilings to
gradually lift toward 3kft by around 04z at ATL TAF sites and a
bit earlier at CSG/MCN. By 07-09z, ceilings should largely
scatter with skies becoming much clearer through Friday morning.
Winds will remain W to NW through the period, initially at 8-12
kts with gusts as high as 18 kts before slackening to 5-8 kts by
12z Friday.

//ATL Confidence...00Z Update...
Medium confidence on MVFR ceiling clearing timing.
High confidence on all other elements.
