Atlanta temperature will rise sharply Wednesday and Thursday before a very hot and humid stretch arrives Friday afternoon and lasts into early next week. People in the southeastern U.S. can expect highs in the 90s, with heat index values approaching 110°F over the weekend.
Storm Team 3 forecast
Wednesday morning starts mainly sunny and very warm, with lows in the mid to upper 70s. Temperatures then climb into the lower and middle 90s, and heat index values can reach 100-105°F at times.
Thursday turns hotter. Morning lows will sit in the lower to middle 70s, then afternoon highs warm into the middle to upper 90s. Heat index values may rise over 105°F during the day.
Friday and the weekend
Friday afternoon begins the hottest and most humid stretch of the forecast. High temperatures Friday and over the weekend stay in the mid to upper 90s, while heat index values approach 110°F at times.
The pattern is not completely dry. A few scattered showers and isolated storms are possible Friday and over the weekend, and any stronger storm would mainly raise concern for damaging wind gusts.
SAVANNAH and the southeastern U.S.
The broader setup shows high pressure building over the southeastern U.S., which helps keep the region hot before the weekend storm chance returns. That leaves a stretch that starts out mainly dry, then turns more humid just as the heat peaks.
For anyone spending long periods outdoors, the practical shift is the timing: the worst heat arrives after Friday and lasts into early next week, not just for one afternoon. The safer window is earlier in the week, before the heat index pushes toward 110°F and before the scattered storms return.
