A cluster of storms is concentrated over the Gulf of Mexico near New Orleans, moving toward the east with potential impacts along the Gulf Coast, including Mobile and Pensacola. Scattered showers are reaching inland over Jacksonville and extending towards the Savannah area. The rest of the Southeast, including cities like Atlanta and Charlotte, remains dry with clear skies, albeit cloudy conditions may be increasing in some eastern parts. Gulf Coast showers persist in proximity to Houston, keeping coastal areas damp, but away from the immediate path of severe weather.
This evening in Atlanta, expect partly cloudy skies initially, transitioning to mostly clear conditions by midnight.

Further east, Atlanta will hit 90, and Jacksonville is close behind at 91. Coastal regions like New Orleans will be a bit cooler at 87, but still above average for this time of year. Expect a hot and humid day across the region, influenced by a strong ridge of high pressure keeping the heat locked in.
A cold front is set to push through the Southeast tomorrow, with storms expected across areas including Jackson, Montgomery, and Atlanta by morning. Expect intense thunderstorms over New Orleans by midday, potentially leading to heavy rainfall and localized flooding through the region.
