Tuesday morning in Atlanta is starting off mostly clear and muggy, with temperatures hovering around 62°F at Hartsfield‑Jackson and a light southwest breeze. A few spotty showers or a stray thunderstorm could pop up through late morning, but the metro area is still on track to warm quickly into the upper 70s. Highs should top out near 78°F this afternoon, and the humidity will keep overnight lows on the mild side.
Forecasters have had their eye on this early March warm spell for several days. Our March 5 coverage, March warmup, flagged both the unseasonable heat and the growing storm threat. Today’s forecast sharpens the timing for a midweek cold front that is expected to push through and flip the pattern to cooler, wetter weather by Thursday, March 12, 2026.
What To Expect
Scattered showers and a 30–40% chance of thunderstorms are in play through Tuesday, with southwest winds around 5 mph and afternoon highs in the upper 70s. According to the National Weather Service in Peachtree City, temperatures will stay well above normal through midweek, roughly 15–20° higher than average, and overnight lows could come close to record‑warm minimums. A cold front sliding through Wednesday night into Thursday, March 12, may trigger more widespread showers and thunderstorms, with some storms strong to severe, wind gusts up to 25 mph, and localized rainfall totals of 0.5–1 inch or more.
Timing And Impacts
The main window for heavier storms is late Wednesday night into early Thursday morning, March 12, which means the Wednesday evening commute could be wet and gusty. Stronger cells may deliver brief damaging wind gusts and knock down a few limbs, so outdoor plans for Thursday morning should come with a backup option. Keep an eye on updated forecasts and be ready to follow any watches or warnings from local officials.
Looking Ahead
Behind the front, highs fall back into the 50s and 60s on Thursday, March 12, with a cooler, drier stretch into Friday and a sunnier weekend on tap. Expect highs near the mid‑60s on Friday and the mid‑70s by Saturday. Another round of afternoon showers is possible Sunday, March 15, as the overall pattern settles down.
