.KEY MESSAGES... Issued at 252pm EDT Monday August 3 2026

- The recent anomalously wet pattern is winding down, and the threat of excessive rainfall is ending. Starting Wednesday, we will fully return to a typical coverage and rhythm of summertime thunderstorms, featuring mainly afternoon and early evening storms, plus morning storms over the Gulf and immediate coast.

.SHORT TERM... (This Evening through Tuesday) Issued at 252pm EDT Monday August 3 2026

The recent anomalously wet pattern is winding down, and the threat of excessive rainfall is ending.

Satellite imagery has nicely shown drier mid- level air, which was over Alabama early this morning, spreading southeast across the rest of the region this afternoon. Where the drier air has arrived, convective coverage has been sharply curtailed today. The drier air will spread across the rest of the service area late this afternoon. We have therefore cancelled the Flood Watch for the last few counties where it was in effect.

The upper trough over the Southeast U.S., which brought the unsettled fast westerly flow along the NE Gulf Coast, is cutting off into a vertically stacked closed low over Georgia. It will start to fill on Tuesday. Over the next 24 hours, this will weaken our westerly low-mid level flow and lessen the potential for focusing thunderstorms into slow-moving lines or clusters like the ones that have brought excessive rainfall recently. Plus, the air mass will simply not be as moist. However, we will still be under a cyclonic flow pattern. Plus, destabilizing cold air aloft will be present near the center of the vertically stacked low over Georgia. So there will still be plenty of showers and thunderstorms through Tuesday, especially during peak daytime heating on Tuesday. Convection will be more spotty, and individual cells will be smaller and shorter-lived.

Long Term
(Tuesday night through next Sunday) Issued at 252pm EDT Monday August 3 2026

The vertically stacked low over Georgia will continue to weaken on Tuesday night and nearly dissipate on Wednesday. On Thursday and Friday, a strong subtropical high out near Bermuda will extend a ridge westward across Georgia and into Alabama, putting the region in low-mid level east-southeast flow from from late Thursday through the weekend.

This will put us back into one of our most quintessential summer patterns. Seasonable temperatures (highs in the low-mid 90s), seasonable dewpoints (mid 70s), seasonable Precipitable Water values in the 1.7 to 2.1 inch range, and a seasonable daily rhythm of scattered seabreeze-focused convection will prevail.

Marine
Issued at 252pm EDT Monday August 3 2026

Low pressure over Georgia and Alabama will weaken through Tuesday night and then dissipate on Wednesday, causing southwest breezes to gradually decrease. The subtropical Atlantic ridge axis will then build westward across Georgia and into Alabama from Thursday through Saturday, bringing a turn to gentle and moderate east and southeast breezes across the waters.

Fire Weather
Issued at 252pm EDT Monday August 3 2026

The region has started a transition away from the recent wet pattern featuring heavy rain at any time of the day or night. Instead by Wednesday, we will have fully returned to a more typical coverage and afternoon rhythm of summertime thunderstorms. Westerly flow across the region will weaken on Tuesday, go light on Wednesday, then turn easterly from Thursday through the weekend. Otherwise, a seasonably hot and unstable air mass will prevail.

Hydrology
Issued at 252pm EDT Monday August 3 2026

The threat of excessive rainfall is ending, and the Flood Watch has been cancelled early. No river flooding is expected.

We now transition back into a more typical summertime hydro regime, in which any concerns are of the short-lived nuisance variety, stemming from brief torrential rainfall rates beneath the core of heavier storms.
