.SHORT TERM...
(Today through Saturday)
Issued at 121 AM EDT Fri Jul 25 2025

Key Messages:

 - Isolated thunderstorms are expected this afternoon, especially
   near the west central Georgia between 2 PM and 8 PM.

 - Heat index values approaching 105 degrees may warrant a Heat
   Advisory for parts of east central Georgia on Saturday (35%
   chance).

Today & Tonight:

Hot and humid weather will prevail in Georgia again today, with the
region stuck between a trough in the Gulf and ridge along the
Carolina Coast. Widespread high temperatures in the lower 90s are
expected, with heat indices peaking 97 to 102 degree range. Diurnal
heating will lead to isolated thunderstorm activity this afternoon.
The highest storm chances are expected in west central Georgia due
to weaker mid level subsidence and weak surface convergence along
and afternoon sea breeze. Any storms may produce frequent lighting,
brief bursts of heavy rain or locally breezy downbursts winds.
Limited shear and poor lapse rates should keep the severe weather
risk very low today. Progressive storm motions should also keep the
flooding risk to a minimum.

Any lingering storm activity should dissipate rapidly after sunset
with the loss of diurnal heating. This will leave the region with
quite weather and lows in the 70s tonight. A couple patches of fog
could occur, but widespread fog is unlikely.

Saturday:

Upper level ridging will drift westwards and establish itself in
Georgia on Saturday. The resulting increase in subsidence will help
temperatures trend upwards and decrease the the potential for
thunderstorms. Afternoon highs should climb by 2 to 4 degrees
compared to today and this will push temperatures closer to Heat
Advisory criteria. This should be especially true in east central
Georgia where afternoon heat index values between 102 and 106
degrees are expected. There is a 35% chance of a Heat Advisory being
issued for counties south of Interstate 20 and east of Macon.

.LONG TERM...
(Saturday night through Thursday)
Issued at 121 AM EDT Fri Jul 25 2025

 - Dangerous heat, in the form of rising temperatures and heat
   index values) remains likely late this weekend through at least
   mid-week.

 - Warm overnight temperatures will do little to provide any
   relief from the heat.

 - Limited daily afternoon and evening thunderstorm chances this
   weekend into early next week are expected, with increasing
   chances by mid-week.

Hot conditions and limited rain chances, at least through
Monday/Tuesday will be the theme to start off the extended period.
Mid and upper level ridging will become centered over the Southeast
through the majority of the period setting the stage for well above-
normal temperatures, rising heat indices, and overall limited rain
and thunder chances through early next week. Strong subsidence
beneath the ridge will keep rain and thunder chances more isolated
in nature than we`ve seen more recently. With the lack of any
steering or notable forcing chances for precip will largely be
determined by local effects (residual or remnant outflows, influence
of sea breezes, etc.). Rain and thunder chances are forecast to
increase starting Tuesday as ridging retrogrades (and somewhat
flattens) in response to troughing across the northeast and low-
level moisture returns to the region. Latest deterministic global
models and ensembles indicate this trend as well as the potential
for a front to slowly sink southward across the TN Valley mid to
late week.

The main story though is the heat. Temperatures are forecast to
steadily climb through the weekend into next week with forecast high
temperatures reaching the upper 90s to low 100s across the majority
of the forecast area (with the exception of the northeast GA
mountains) by Sunday and lasting through Wednesday. Even for mid to
late July, these temperatures are well above normal -- some 7 to 12
degrees above. Heat index values are also forecast to meet or exceed
105 each afternoon across the majority of the area. With some
locations, especially across Central GA reaching or exceeding heat
index values of 110 (Extreme Heat Warning Criteria) from Monday to
Wednesday. Please keep the heat in mind if you (or your family or
pets) plan to spend any amount of time outdoors! Unfortunately, once
the sun goes down, there will be little reprieve from the hot and
humid conditions. Forecast lows will range from the mid 70s to low
80s each night (upper 60s to low 70s in the northeast GA
mountains).

.AVIATION...
(06Z TAFS)
Issued at 142 AM EDT Fri Jul 25 2025

Patchy fog or low ceilings (100-1000 ft AGL) will be possible in
north and central Georgia between 08z and 14Z Friday. The odds of
impacts at any of the regional TAF sites are less than 20%.
Isolated thunderstorms will be possible between 18Z Friday and 01Z
Saturday, with KCSG having the best odds of impacts. Winds will be
from the south or southwest (160-240 degrees) at 3 to 10 kt through
Saturday.


//ATL Confidence...06Z Update...
Very low confidence in the occurrence of ceiling or visibility
restrictions between 09Z and 13Z today.
High confidence in south winds today, but they may waffle around
180 degrees.
Low confidence in the occurrence of storms between 21Z today and
01Z Saturday.
