.SHORT TERM...
(This afternoon through Monday)
Issued at 234 PM EDT Sun Apr 21 2024

The light rain and overcast conditions will gradually taper from
west to east through the remainder of the afternoon. Clearing skies
are already widespread just across the border in Alabama as a drier
airmass spreads eastward. This clearing trend should allow the chilly
temperatures across portions of west/northwest Georgia (currently in
the upper 40s to lower 50s) to rebound a bit this afternoon. Still,
temperatures will struggle to approach the 60 degree mark through the
remainder of the day across much of north Georgia. The incoming
drier, cooler airmass will bring much chillier overnight
temperatures, particularly to north Georgia where lows will dip into
the upper 30s for a number of locations by Monday morning. The
coldest temperatures will be in the northeast Georgia mountains where
mid 30s are forecast. While winds will remain fairly elevated and
prevent widespread frost formation, a Frost Advisory covers Fannin,
Union, and Towns counties where winds will taper early Monday morning
and could lead to areas of frost, particularly in protected areas.

Surface high pressure will settle into the region on Monday bringing
mostly sunny skies. High temperatures will remain some 6-10 degrees
below normal, ranging from the mid 60s to near 70 degrees. With high
pressure overhead bringing calm winds and clear skies, temperatures
Monday night will again be on the chilly side, ranging from the upper
30s to mid 40s across the area.

.LONG TERM...
(Tuesday morning through next Saturday)
Issued at 234 PM EDT Sun Apr 21 2024

Quasi-zonal flow in mid mid levels early in the week turns more NW
by late week as ridging builds in the center part of the county. The
ridge will shift eastward and remain overhead through the weekend.
The models are progging two strong pieces of shortwave energy to
impact the CWA in the long term, one late Wednesday/early Thursday
and the second for the weekend. At the surface, high pressure
overhead on Tuesday will begin to shift offshore by early Wednesday
as a weak boundary approaches from the north. The boundary is progged
to sag southward as a back door front through the remainder of the
weekend with a wedge building in from the NE.

Thursday`s surface boundary doesn`t look to have a lot of moisture
associated with it, but it could bring some small potential for
precipitation. Will have to watch the shortwave diving down in the
flow during this period, as it could interact with the front
providing more lift than currently forecast. The models are currently
dry. The shortwave energy for the weekend could also provide just
enough lift within the wedge for very light precip.

.AVIATION...
(06Z TAFS)
Issued at 147 AM EDT Mon Apr 22 2024

VFR conditions are expected for the period. Lingering wrap-around
cloudiness continues to push E, but lowest cig heights are over 3500
feet at AHN, and these clouds will be thinning and lifting over the
next few hours. Remaining mid and upper level clouds will be thinning
as well. Winds will be generally light, although some gusts to
around 18 knots are expected this afternoon at CSG. The wind
direction will be veering to NE around 14Z at most sites before
backing to NW around 19Z.

//ATL Confidence...06Z Update...
Medium for timing of wind shift to NE. High for all other elements.
