.SHORT TERM...
(This afternoon through Saturday)
Issued at 220 PM EDT Fri Aug 21 2026

An upper level longwave trough currently extends from the northern
Great Lakes towards the Deep South, and will continue to amplify as
its axis shifts eastward towards the Atlantic coast. A surface front
associated with this trough has entered far northwest Georgia. The
movement of the trough will help advance the frontal boundary south
and east through the afternoon and evening. Areas along and south of
the front will be the focus for thunderstorm activity amid a warm
and moist environment. Temperatures in portions of central and east
Georgia will climb into the into the mid to upper 90s (compared to
low 90s in areas north of I-85) while dewpoints remain in the low
90s. Robust destabilization within this hot and humid airmass
combined with forcing ahead of the front will allow storms to
develop quickly during the remainder of the afternoon. This will
culminate in high-end chance to low-end likely PoPs in areas
generally south/east of Atlanta from 4 PM to 8 PM, with gradually
diminishing chances during the evening with the loss of daytime
heating.

With SBCAPE values between 2500-3500 J/kg, DCAPE values between 800-
1200 J/kg, and precipitable water values of 1.9-2.2 inches, several
storms this afternoon and evening will be capable of becoming
severe. Downburst winds up to 60 mph will be the primary threat with
any severe storms that occur, which will be capable of damaging
trees and powerlines. Storms over the course of the day will also
contain frequent lightning and be highly efficient rainfall
producers given deep moisture. This could lead to isolated flooding
concerns, especially if stronger storms linger over urban or flood-
prone areas.

On Saturday, the trough axis will clear Georgia to the east, pushing
the frontal boundary through the forecast area. Noticeably drier air
will filter in behind this front, lowering dewpoints into the 60s
across the majority of the area. Though highs will still rise into
the low 90s, it will feel less oppressive given these dewpoints. An
isolated shower or thunderstorm cannot be ruled out in east-central
Georgia closest to the front on Saturday afternoon, while clear
conditions are forecast elsewhere across the forecast area.

.LONG TERM...
(Sunday morning through next Thursday)
Issued at 220 PM EDT Fri Aug 21 2026

By the end of the weekend, temps will have fallen into the upper
80s and low 90s with RH values in the afternoon will drop into the
mid to low 40s bringing heat index values down and making it feel
very dry for this time of year. A welcome relief from the hot an
humid weather that had seem to be stuck over GA for the past
month.

With this dry airmass behind the front, we`ll also get a break from
thunderstorms during the afternoon as well until Wednesday when
winds become more southerly and we start to pull moisture back in
from the Gulf. This weekend and early next week will be a great
opportunity to be outside without hating it.

After Wednesday, the upper level flow becomes more zonal and we`ll
start to see a return to the diurnal pattern that we are used to.
With that pattern, we are also expecting a slow return of triple
digit heat indices for the second half of the work week.

(06Z TAFS)
Issued at 109 AM EDT Sat Aug 22 2026

Mostly VFR though a period of patchy SCT MVFR and IFR cigs may
develop most likely between 08-12z. Patchy low cigs 4-6SM also
possible. Light and VRB wind overnight picking up from the NW for
the northern sites and SW to W at the southern sites. Once the front
clears CSG/MCN winds will veer NW. Speeds 5-8kts. Iso to Sct tsra
Sat aftn mainly south of MCN and CSG. Chances too low to mention in
TAF at this time.

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

Medium confidence on lower cigs tonight.
High confidence on all other elements.
