  and capable of producing gusty to damaging wind gusts up to
  50-60 mph, locally heavy rainfall, and frequent lightning.

.SHORT TERM...
(This afternoon through Sunday)
Issued at 213 PM EDT Sat Jul 11 2026

Heat continues to be the primary concern with another heat advisory
in effect for this afternoon. Apparent temps between 100-105 are
expected in the southeast corner of our CWA and given the pattern in
place, it will likely be needed again tomorrow. The rest of the CWA
falls just short of Heat Advisory criteria, though triple digit heat
index values are still likely.

Across the northern part of the state, temperatures will be less
extreme but that comes with a severe weather risk. Ongoing
thunderstorms across the NE part of the CWA this morning will likely
continue this afternoon and become more widespread along and north
of I-20. The SPC has us in a slight risk and while sheer values
remain on the low side, the proximity to a slow moving front just to
our north combined with afternoon CAPE values coming up on 3k J/kg
are enough to give us the confidence to say that any storm that
forms will have the environment it needs to over achieve. The main
threat will be damaging winds, but small hail will also be possible.

Thunderstorm threat will continue tomorrow afternoon, with the main
focus again across north and eastern Georgia. Like today, storm
motion appears to be quasi-linear with a loose line of storms
expected again tomorrow afternoon that has the potential to bring
with it some wind damage. Given multiple days of possible severe
weather, localized flash flooding is also expected to become more of
a concern over the next 36 hours, especially in low lying areas and
the metro.

.LONG TERM...
(Monday morning through next Friday)
Issued at 213 PM EDT Sat Jul 11 2026

Definitely looks to be a wet front end of the long term forecast
period before settling back into a more typical summertime pattern
across the CWA. Looking aloft, upper level low that is progged to
cut off from the upper level flow slowly progresses into the area on
Monday. Pretty high confidence in the progression of this system
across the ensembles given the cut off shows up in the ensemble
mean, which is good to see provided things aren't underdispersed.
NAM even has a low level reflection of the low clearly stationed
over north Georgia on Monday. This upper level low will provide both
forcing and upper level cooling that will allow for widespread
showers and thunderstorms across the area on Monday. The good news
is that widespread rain and cloud cover will at least provide some
temporary relief to the heat, with highs in the 80s for all but east
central Georgia which will keep heat index values in the 90s. Much
better than our repeated days of 100s.

Tuesday looks to be wet as well as the system appears to pivot over
the area. Ensembles show strong anticyclonic wave break over the
northern portions of the CONUS which reflects on 500 mb pattern as
strong ridge centered over the north. Our little cutoff will likely
be filling in and looks like it should get shunted to the west by
Wednesday into Thursday, which would bring our precipitation chances
back into normal diurnal ranges. Temperatures also slowly rebound
through the week, returning to the 90s and heat indices in the 100s
by the end of week. You know you weren't going to get an extended
break from the heat in July in Georgia.

.AVIATION...
(06Z TAFS)
Issued at 137 AM EDT Sun Jul 12 2026

Primarily VFR conds are expected until late pd, with SCT-BKN cigs
at 3-7kft to linger into the aftn. Coverage of SHRA and TSRA will
be higher than in previous days. Iso SHRA psbl thru 10Z. Best
window for impacts in TSRA for northern TAF sites will be 17-21Z,
with a secondary peak between 01-06Z. Heaviest pcpn may be
accompanied by MVFR vsbys in BR. Winds will remain out of the
W/WSW at 5-10kts. Chcs for BKN IFR cigs will increase following
second round of SHRA/TSRA, generally aft 07Z.

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

High confidence all other elements.
