Atlanta is waking to clear skies and temperatures around 57 degrees Sunday, with sunshine pushing the afternoon high to about 81. It is a brief taste of fall before summerlike heat starts creeping back into the forecast.

The day should stay dry from morning through evening, though a light northwest breeze is expected, according to the National Weather Service. Sunday night will be mostly clear with a low around 56 and light winds.

Sunny Stretch Turns Warmer Quickly

Monday will remain sunny with a high near 84, followed by another sunny day Tuesday reaching about 86. Winds should stay light, making for comfortable mornings and increasingly warm afternoons across the Atlanta area.

Wednesday and Thursday are expected to be the warmest days of the stretch, with highs near 89 and overnight lows rising into the mid-to-upper 60s. The air will remain unusually dry, and forecasters say humidity could approach a near-critical threshold for fire weather Tuesday afternoon, so outdoor burning deserves extra caution even without a formal warning.

Rain Chances Return Late In The Week

Friday brings a chance of showers and storms, with highs in the lower 80s to mid-80s. Saturday also looks unsettled, with a chance of showers and storms and temperatures reaching about 85.

No watches, warnings or advisories are in effect for the Atlanta forecast area. For now, Sunday through Thursday look like the window for dry outdoor plans, with umbrellas becoming more useful by Friday afternoon.
