.SHORT TERM...
(This evening through Monday)
Issued at 301 PM EDT Sun Jul 27 2025

Key Messages:

 - Hot conditions will continue in Georgia through at least
   Monday.

 - A Heat Advisory is in effect for most of the area through
   Monday, with an Extreme Heat Warning along portions of the
   Oconee River on Monday.

 - Isolated thunderstorms, with the potential for strong
   downburst winds, may return to portions of Georgia on Monday.

Hazardous heat will continue to be the primary concern through
at least Monday as a ridge sits over the Southeast U.S. High
temps today will climb into the mid to upper 90s, with heat index
values of up to 109. A Heat Advisory is in effect for most of
east-central GA today where peak heat index values will be above
105. On Monday, the airmass over Georgia will slightly warm as
the ridge starts to shift west over the lower Mississippi Valley.
This will result in temperatures warming a few degrees from today,
prompting another Heat Advisory across most of east-central GA
where afternoon heat index values will be over 105. Portions of
the area along the Oconee River are in an Extreme Heat Warning on
Monday, with heat index values of 110-112 expected. There is some
potential for the area under a Heat Advisory to expand in future
forecast packages based on the latest trends. The other impacts
of the ridge axis sliding west are decreasing subsidence and a
slight increase in mid-level moisture moving in from the north.
This will combine to support isolated afternoon showers and
thunderstorms, some of which may be strong with downburst winds as
the primary threat.

.LONG TERM...
(Tuesday morning through next Saturday)
Issued at 301 PM EDT Sun Jul 27 2025

Key Messages:

 - The heat wave and hotter than normal temperatures will persist
through at least Wednesday. Temperatures will lower late in the week
into next weekend.

 - Warm overnight temperatures will do little to provide any relief
from the heat on Tuesday and Wednesday.

 - Chances for showers and thunderstorms will increase from Tuesday
afternoon through remainder of the week. Thunderstorms capable of
producing 40-50 MPH downburst winds will be possible on Tuesday and
Wednesday.

The 500 mb ridge responsible for the recent run of hotter than
normal conditions will be flattening and retrograding to the west as
the long term period begins on Tuesday. Also, as a surface low
develops to the east-southeast of the forecast area, low level
moisture will also begin to increase over Georgia with easterly flow
on the backside. The coverage of diurnally driven storms is thus
expected to become scattered to numerous across the area on Tuesday
and Wednesday. Ample instability will be present with increasing
moisture and still above normal temperatures across the area. Model
forecast soundings also reveal inverted V soundings, indicating the
potential that some storms on Tuesday and Wednesday afternoon could
become capable of producing strong downburst winds. Locally heavy
rainfall and frequent lightning will also be present with any storms
that develop.

In spite of the slightly "cooler" temperatures (largely in the mid
to upper 90s) due to the increased afternoon PoPs and cloud cover,
the dangerous heat will persist with increasing dewpoints allowing
for heat indices to climb to between 103 and 109 once again on
Tuesday and Wednesday afternoon. Low temperatures will also be
between 5-10 degrees above normal on Tuesday and Wednesday
morning, in the mid upper 70s each both mornings. Unfortunately,
this means that overnight relief from the heat will be difficult
to come by during the early parts of the week. Additional heat
headlines could be needed on Tuesday and Wednesday, and those with
plans to spend time outside on those days should be mindful of
heat stress and signs of heat exhaustion and wear light, loose
fitting clothing, hydrate frequently, and take frequent breaks in
the shade or indoors.

A frontal boundary will sink southward through the Tennessee Valley
region and towards north Georgia late this week, with increased rain
chances expected to continue on Thursday and Friday in the region of
forcing ahead of the front. Following the front, a wedge front is
anticipated to set up the northeast part of the state. The influence
of this wedge will promote noticeably lower temperatures on Friday
and into the weekend.
