.SHORT TERM...
(Today through Tuesday)
Issued at 416 AM EDT Mon Apr 29 2024

Expecting another dry day today with highs in the low 80s for much
of the area before the sfc high pressure retreats to the east and a
mid level trough moves into the southeast overnight into Tuesday. The
associated energy with this shortwave brings showers into north GA
as early as 2-4am Tuesday before pushing further into north and
central GA. Currently with the timing, the energy remains cut off
from much of the instability so not expecting anything other than
isolated thunderstorms overnight. As the showers move into central
GA and line up with the better instability, this may be where we see
more thunderstorms activity. Not expecting anything severe, but
could see isolated to scattered strong thunderstorms if the moisture
sticks together through the afternoon. SPC currently has us under a
general thunder risk which goes along with current thinking.

.LONG TERM...
(Tuesday night through Sunday)
Issued at 416 AM EDT Mon Apr 29 2024

At a glance:

- The second half of this week will be hot.

- Chance for thunderstorms on Saturday afternoon across northern
Georgia.

Well, it`s summer. The ridge will settle in over the Atlantic
Georgia will begin to bake until likely the end of the season.
Temperatures are expected to climb into the mid to upper 80s on
Wednesday afternoon and will stay there through the rest of the long
term. Overnight lows will be in the low to mid 60s so the AC will
probably need to work overtime.

A short wave will bring the chance of thunderstorms north of I-20 on
Friday night and into Saturday. This may help moderate temps in
northern Georgia to the mid 50s. While that wave is expected to
clear the area by Sunday, winds will shift to the SSW by the end of
the weekend providing the CWA with enough moisture to kick off pulse
convective season. As a result, most of the CWA has at least a
slight chance for PoPs in the early afternoon beginning Sunday.
