.SHORT TERM...

(Today through Sunday)

Issued at 233 AM EDT Sat Jun 20 2026



A frontal boundary has stalled out just south of the I-20

corridor, creating a sharp moisture gradient across our area

today. North of the boundary, which includes most of the Atlanta

metro, today will be mostly dry with only a few showers or weak

storms around during the afternoon. Lower dewpoints in this area

will make it feel less humid than recent days, with highs topping

out in the upper 80s. For areas south of the boundary

(central/southern GA), the warm and humid airmass will persist,

supporting scattered to numerous showers and storms from late

morning through the evening hours. A few storms could be strong, 

with gusty winds, frequent lightning, and heavy rainfall. We will

have to watch out for localized flash flooding, especially if 

areas hit hard in recent days are hit again. Temperatures will

rise into the mid to upper 80s, with heat index values peaking in

the mid to upper 90s.



On Sunday, low to mid level winds over the region will increase 

out of the southwest in response to a system over the Midwest,

pushing the frontal boundary back north out of our area. The warm

and humid airmass will spread back north across all of North and

Central GA, resulting in high temps in the upper 80s to low 90s

and heat index values in the mid to upper 90s. Subtle mid-level 

ridging will try to keep a lid on convection, but isolated to

scattered showers and storms will still break through during the

afternoon and evening.

.LONG TERM...

(Sunday night through Friday)

Issued at 233 AM EDT Sat Jun 20 2026



To begin the period, upper level high pressure will be situated 

the south of the region with NW flow aloft. This will set the 

stage for an unsettled weather pattern with summer afternoon 

convection likely most days in the long term period. 



Low end rain chances will be possible each afternoon next week as

ridging builds in to the south. This will promote more humid 

conditions across the state, with a summer-like pattern likely 

this upcoming week. Afternoon convection will be possible each 

day, with afternoon rain chances around 30-40 percent. Coverage 

would not be widespread but more scattered and strong to severe 

storms possible.



Temperatures are expected to be average to slightly above average

as high pressure settles south of the state. Max heat index 

values will return to the upper 90s to near 100 degrees for 

central and southern locations.

.AVIATION...

(18Z TAFS)

Issued at 146 PM EDT Sat Jun 20 2026



Scattered TSRA has begun to develop in portions of central

Georgia, which will persist through the late afternoon. A TEMPO

for TSRA is in place from 19-23Z for CSG/MCN. Isolated storms

could spread as far north as I-20, warranting a PROB30 for TSRA 

at ATL from 20-24Z. SHRA/TSRA coverage will diminish after

sunset. Conditions are largely VFR (aside from lingering MVFR 

ceilings at CSG), with a cu field around 4-5 kft under broken mid-

level clouds. Widespread IFR ceilings are likely to develop after

08Z at CSG/MCN. Scattered IFR could spread as far north as ATL 

after 10Z. Winds have shifted to W at 4-8 kts and will remain so 

until becoming light and variable overnight.



//ATL Confidence...18Z Update...

Medium confidence on TSRA chances this afternoon 

Medium confidence on scattered low clouds at ATL on Sunday 

morning.

High confidence on all other elements.
