.KEY MESSAGES...

 - Scattered to numerous thunderstorms this afternoon may pose
   a damaging wind gust threat across Central Georgia. Frequent
   lightning and locally heavy rainfall possible with any storms.

 - Warm and humid again today but slightly `cooler` and more seasonal
   temperatures return this weekend into early next week.

 - Mostly dry this weekend with low daily rain chances returning
   for most by mid-week next week.

.SHORT TERM...
(Today through Saturday)
Issued at 350 AM EDT Fri Aug 21 2026

Currently: Thunderstorms are ongoing across North Georgia early this
morning. Convection pulsed up fairly quickly upon entering the
forecast area given the mostly untapped environment. And storms
initially presented not only a severe wind threat but also a
flash flooding risk due to the slower movement of storms. The most
impressive was noted in Catoosa County in which the northern
parts of the county received well over 3 inches of rainfall in an
hour with a few spots between Ringgold and Boynton having radar
estimates of up to nearly 4" in a little over an hour! While a few
additional severe pulses cannot entirely be ruled out over the
next hour or two, anticipating storms will gradually wane and lose
steam as outflow races out ahead.

Additional Thunderstorms This Afternoon:

Most of North Georgia will be fairly worked over and baring any
recovery, additional thunderstorm development is largely expected
over Central and Eastern Georgia this afternoon into the evening
where the highest moisture and instability will lie. A surface front
will slowly sag south later today and areas along and south of this
feature will be the focus areas for convective development. Storms
may be capable of severe wind gusts in these areas as highlighted by
the Marginal Risk Area (Level 1 of 5) in the Day 1 Severe Outlook by
SPC. Heading into Saturday the surface front should be across our
far southern counties thus, rain and thunder chances will be very
limited and mostly confined to far south-central GA.

Heat Trends:

Less oppressive heat is on the horizon but not before one more day
of hot and muggy conditions. With a warm and humid airmass still in
place, temperatures will climb back into the 90s (except the higher
elevations) this afternoon. Triple digit heat indices are forecast
for most places today and nearing heat advisory criteria for
parts of Central GA. An advisory was considered but the potential
for higher convective coverage this afternoon elected to hold off.
Regardless, continue to take extra care of yourself and others
(including pets!) if you are outdoors today. Drier and less humid
air will begin filtering in behind a frontal boundary tonight into
Saturday. This will stick with us through the weekend.

.LONG TERM...
(Saturday night through Thursday)
Issued at 350 AM EDT Fri Aug 21 2026

The long-term forecast indicates a pronounced ridge centered over
the Four Corners region, with an upper-level trough extending
southward from the Midwest. This setup will push a front through
the area Saturday and usher in drier air through the day, with
dewpoint temperatures dropping into the 50s to mid 60s across our
CWA by Sunday afternoon. As such, expect mostly fair weather with
slightly cooler mornings through the weekend into early next week,
with daytime high temperatures ranging from the upper 80s to low
90s and lower RH values.

A few stray showers or storms will be possible across the southern
portion of our CWA Saturday afternoon; otherwise, the frontal
boundary should come through mostly dry and bring an end to the
precipitation chances through Monday morning. By mid-week, the upper-
level flow becomes more zonal, and conditions begin to favor the
typical diurnal thunderstorm and humid pattern we so often
experience during the month of August. As a result, we will need to
keep an eye on heat index values across the CWA during the second
half of next week.

.AVIATION...
(06Z TAFS)
Issued at 104 AM EDT Fri Aug 21 2026

Mostly VFR through the period. A semi-organized line of tsra has
now formed and is moving ESE into North Georgia. Maintain tsra
wording in the northern terminal TAFs with timing roughly 08-12z.
Confidence is still low give slow movement and current trajectory.
There is still a non- zero chance tsra falls apart or tracks just
to the north of ATL. But we could still see strong VRB winds up
to 35-40kts with the GF. Cu field of 3-5kft will develop in the AM
with additional chances for tsra as early as 17-19z. Largely VRB
wind through the night outside of tsra, but favoring W side less
than 10kts after 15z.

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

Low confidence on overnight tsra forecast.
High confidence on remaining elements.
