Atlanta woke up to clear skies and about 63°F at Hartsfield-Jackson on Wednesday morning, and the warmup will be quick. Forecasters say sunshine will send temperatures near 83°F on Wednesday, April 22, 2026, setting up a warm and very dry afternoon across the metro.
That warmth is teaming up with unusually low humidity, with readings expected to drop into the 20–30 percent range this afternoon and early evening. Grass, brush, and fallen leaves are already dried out, so even with light winds, the combination of dry fuels and several hours of low humidity has prompted a fire-weather alert for much of metro Atlanta.
Fire Weather And What It Means
The concern is less about how strong the wind blows and more about how quickly a spark can turn into a problem. In a Special Weather Statement, forecasters spelled out the risk clearly: "Relative Humidities of 30 percent or less can be expected for 4 or more hours this afternoon into the evening," the National Weather Service office in Peachtree City noted. That product warns of high fire danger while fuels remain dry and urges residents to check local burn permits and avoid open burning. For the official statement see National Weather Service Peachtree City.
When Rain Returns
The dry stretch is expected to hold through Friday, so the fire risk will not vanish overnight. Showers and thunderstorms are likely on Saturday, April 25, with the highest chance of rain that day and a forecast high near 78°F. The unsettled pattern hangs around into Sunday and Monday, and another round of more widespread showers and storms is possible Monday night into Tuesday, April 28, so outdoor plans may need a backup option.
What To Do
If you have yard work, land clearing, or evening hangouts planned today, put off any open burning and keep grills and fire pits under close watch. Outdoor workers and athletes should be ready for the heat while avoiding any activities that could kick off a spark, and everyone should keep a hose, bucket of water, or fire extinguisher nearby in case a small fire starts.
Legal Implications
Some Georgia counties enforce an annual ban on open burning that typically begins May 1. Even where that seasonal ban is not yet in effect, local governments can issue temporary burn restrictions during periods of high fire danger. Before lighting anything, check state guidance along with your county permitting office. For details and a list of affected counties, see the Georgia Environmental Protection Division.
