.SHORT TERM...
(Today through Thursday)
Issued at 316 AM EST Wed Jan 15 2025

Key Message:

 - Quiet weather will continue in the region today.

 - Breezy westerly winds should develop on Thursday, and a Wind
   Advisory may be considered (50% chance) for a portion of north
   Georgia.

For Today & Tonight:

A weak surface high and westerly flow in the upper levels will
prevail over the Southeast today. Moisture from the Eastern Pacific
will advect over Georgia via the westerly flow, leading to some high
level cloud cover. This cloud cover could inhibit afternoon
temperatures a bit, especially in central Georgia, though for now
our forecast afternoon highs are near seasonal averages. This is a
degree to two warmer than the previous forecast. The benign weather
should continue as temperatures dip into the 20s tonight.

Thursday:

A shortwave trough will track through the Ohio Valley on Thursday.
No precipitation is expected from this feature in Georgia, but it
should bring breezy west winds. Guidance from the HREF suggests a
50% or better chance for wind gusts over 30 mph along and north of
Interstate 20, and this is supported by favorable 850-700 mb flow
and potential boundary layer mixing. Gusts in the 20 to 30 mph range
are more likely in central Georgia. Given these expectations a Wind
Advisory is possible (50% chance) for a portion of north Georgia on
Thursday. The westerly winds and sunny skies should combine to bring
4-8 degrees of warming to the region Thursday afternoon.

.LONG TERM...
(Thursday night through Tuesday)
Issued at 316 AM EST Wed Jan 15 2025

At a glance:

 - Temps will be pleasant this week before the next weekend`s
   rain.

 - Gusty winds will be likely through the week.

High pressure will dominate much of the southeast with it`s center
over the panhandle of FL. This will allow high temperatures to
recover to seasonal or even slightly above with highs in the 40s,
50s and even 60s toward the end of the work week. Wind gusts as high
as 15-20mph will be likely this week.

Toward the end of the week, the next system approaches. Rain is
expected to begin on Saturday morning and push off by Sunday
morning. Rainfall totals have come up some, with amounts ranging
from 1-2".

Sunday afternoon and into Monday will give us a chance to dry out,
but temps drops pretty substantially behind that system. Confidence
in a gulf low is growing as models are coming into agreement with
timing and formation. The system tries to push into southern GA on
Tuesday afternoon and given the cold air in place, at least some
kind of rain snow mix appears likely in the souther portions of our
CWA.
