.SHORT TERM...
(Today through Saturday)
Issued at 222 AM EDT Fri Sep 4 2026

The ridge that has been responsible for our recent stretch of
relatively hot and humid weather will remain parked over the area
again today. Under mostly sunny skies and light easterly winds,
muggy low temps in the 70s this morning will rise to the 90s by
the afternoon. Heat index values will peak in the 100-105 range,
highest in Northwest GA where a Heat Advisory is in effect through
this evening. Across Central GA, there will be potential for some
relief from the heat this afternoon as some moisture surges in
from the south and supports scattered afternoon showers and
storms. These will be our typical summertime pop-up storms,
capable of producing gusty winds, frequent lightning, and locally
heavy rainfall.

On Saturday, the persistent ridge will finally start to be pinched
westward as broad troughing nudges in from the northeast. Even
with this slight shift in the pattern, it will be another day of
highs in the 90s and heat index values in the triple digits as the
hot and humid airmass persists. Sufficient moisture and
instability will support isolated to scattered afternoon showers
and storms across the area. A few members of the high-resolution
model suite have a weakening line of storms moving from TN into
North GA during the evening to overnight hours associated with a
shortwave, but confidence in this threat is quite low at this
time.

.LONG TERM...
(Saturday night through Thursday)
Issued at 222 AM EDT Fri Sep 4 2026

The long-term pattern begins with the upper-level ridge
temporarily shifting westward allowing for greater influences of
an upper-level through anchored along the eastern seaboard. On
Sunday, a few impulses of instability will move along the trough
and eject into the CWA preceding a weak backdoor `cold` front.
This will contribute to the possibility of more organized showers
and thunderstorms Sunday afternoon through the overnight period.
As such, some of these storms could be strong to isolated severe
with Machine learning (ML) models highlighting some risk over the
CWA. The main consideration is how much instability remains over
our area during the period of increased forcing and that is to be
determined. All that being said, the primary threat from these
storms would be strong to damaging wind gusts, frequent lightning,
and heavy rainfall.

Beyond the weekend, temperatures will start off a little cooler
on Monday with increased cloud cover behind our front as the
upper- level ridge begins to pendulum back toward our area into
the first of next week. Expect temperatures to climb back into the
low to mid 90s through the week along with the isolated to
scattered diurnal thunderstorm chances.

.AVIATION...
(06Z TAFS)
Issued at 156 AM EDT Fri Sep 4 2026

Mostly SKC and VFR conditions across the area early this morning,
except patchy FG and IFR CIGs possible around MCN from 10-14Z. CU
fields of 4-5kft develop this afternoon, with SCT SHRA/TSRA
around the CSG and MCN sites through the evening. There is potential
for an ISO SHRA/TSRA as far north as ATL, but chances are too low
to include. Winds light and variable through the morning,
becoming E-SE at 5-8 kts during the day on Friday.

//ATL Confidence...06Z Update...

High on all elements.
