.SHORT TERM...
(This afternoon through Wednesday)
Issued at 227 PM EDT Tue Apr 8 2025

No changes to the current frost/freeze headlines.

500mb analysis shows a longwave trough moving through the SE
states this afternoon. This trough will move east overnight with
NW flow aloft setting up through the end of the short term period.
At the surface, a secondary cold front is situated across
portions of north GA. This boundary will continue to push south
through the evening with high pressure building in from the north.
High pressure center will slide off the DELMARVA coast by early
tomorrow with a shallow wedge building in from the NE.

Wind gusts should diminish shortly after sunset this evening and
then go light NW. A wind shift to the NE/E is expected before
sunrise tomorrow as a wedge builds in from the NE. Winds should be
light enough overnight for some frost formation, especially in
areas along the GA/AL state line, where winds will take longer to
shift to the east and pick up in speed. Good radiational cooling
is likely and temperatures near freezing are possible across north
and northwest portions of the state.

.LONG TERM...
(Thursday morning through next Monday)
Issued at 227 PM EDT Tue Apr 8 2025

Key Messages:

 - Isolated strong or severe storms may occur in northwest
   Georgia Thursday afternoon and evening.

 - Freezing or near freezing temperatures may develop in
   north Georgia Friday night and Saturday night.

Next Storm System Thursday & Friday:

Scattered rain showers and thunderstorms should return to Georgia
on Thursday as the next upper level trough deepens over the
Eastern U.S. Ensemble trends favor northern Georgia for the
highest rainfall chances due to greater moisture availability and
proximity to the trough (better upper level support). Though not
spectacular, mid 50s surface dewpoints may be in place across
north Georgia by Thursday afternoon. This may combine with mid-
level lapse rates (700-500 mb) greater than 7 C/km and diurnal
heating to produce 500 to 1250 J/kg of MUCAPE Thursday afternoon
and evening. Note that this degree of instability is heavily
dependent on dewpoints recovering into the 50s. Assuming that the
instability is present, bulk shear (0-500 mb) values near 50 kt
indicate some potential for a couple strong or severe
thunderstorms. At this time the favored storm mode looks to be
isolated cells or small bowing segments, and hail or damaging
winds would be the main concerns. The SPC has highlighted this
risk my placing northwest Georgia in a Marginal Risk (level 1 of
5) for severe weather in the Day 3 outlook. The potential for
storms of any kind should decrease quickly as you move south into
central and southern Georgia.

Breezy northwest winds behind the passage of the cold front
should usher in cooler temperatures on Friday. Light rain showers
and mostly cloudy skies may linger over north Georgia during the
day on Friday due to the regions proximity to the upper level
trough (which will be lingering over the southern Appalachians).
Thunderstorms and severe weather are unlikely on Friday due to
decreased instability.

The Weekend & First Half of Next Week:

As surface high pressure settles into the region on Saturday
lighter winds will develop and temperatures will bottom out.
Afternoon highs should be 7 to 12 degrees below seasonal averages.
This equates to lower 60s in north Georgia and upper 60s in
central Georgia. The potential exists for this forecast to trend
down by several degrees as both the EPS and GEFS means are
slightly below the NBM mean. It is possible that the NBM`s bias
correction is keying on recent warm weather and adjusting temps
upwards to much. Frost and or Freeze products may need to be
considered for portions of north Georgia Saturday night (odds of a
Frost Advisory 45%, Odds of a Freeze Warning < 20%). As we
progress into next week temperatures should gradually warm as the
surface high shifts out into the Atlantic. By Monday widespread
high temperatures in the lower 80s are favored. No precipitation
is expected in the region between Saturday and Tuesday.

.AVIATION...
(00Z TAFS)
Issued at 740 PM EDT Tue Apr 8 2025

VFR conditions will prevail through the period. FEW Cu may
develop across the eastern half or so of the state as a cold air
damming "wedge" moves in from the Carolinas overnight into
tomorrow (Wednesday) morning. Breezy NW winds are abating this
evening and will soon become light (~4 kts or less). Winds will
then shift to the NE at AHN ~07z, at ATL and the other metro sites
between 09z and 11z, at MCN ~12z, and at CSG ~14z. Wind speeds
tomorrow will be 8-13 kts with gusts up to ~20 kts.

//ATL Confidence...00Z Update...
High confidence on all elements.
