.SHORT TERM...
(Today through Sunday)
Issued at 329 AM EDT Sat Sep 19 2026

High pressure wedge/ridge continue to weaken and moisture pushes 
SW down the eastern seaboard. This increased moisture combined 
with high temps in the lower to middle 90s will keep precip 
chances elevated through the weekend. A weak backdoor cold front 
along the NC/SC border will keep moving SW and push into east GA 
this afternoon. A decent amount of low to mid level moisture will 
accompany this boundary as Dewpoints expected in the 70s across 
North and Central GA Today. Combined with an axis of moderate 
instability we will see scattered to numerous showers and 
thunderstorms this afternoon and evening. Low level lapse rates 
expected to become fairly steep again this afternoon so looks like
the greatest threat from any storms that develop will be strong 
gusty winds again. We will also see frequent lightning strikes and
periods of heavy rain. 

Moisture continues to increase from the NE through the beginning
of the work week keeping PoPs in the scattered range (30-50%). 
Temps also stay in the 90s through the short term so a similar 
threat of severe storms also continues. The current general and 
marginal risk areas of severe storms from SPC look good across the
region.

.LONG TERM...
(Sunday night through Friday)
Issued at 329 AM EDT Sat Sep 19 2026

The ridge is finally expected to break down Sunday night into 
Monday as another front approaches from the Mid MS river valley. 
Isolated thunderstorms become more widespread beginning Monday 
afternoon. We'll see storm chances between 50% and 75% through 
Tuesday before another ridge turns the flow more NW and we get cut
off from the Gulf moisture towards late part of the work week. 

This will help to moderate temps down to the upper 80s and low 90s 
by Wednesday and settle into the mid to low 80s towards the end of 
next week as the dry air clears out afternoon convection chances. 
Low Temps will drop back into 60s Wednesday night into Thursday and 
we'll get a pleasant taste of fall.
