The National Weather Service (NWS) in Peachtree City has issued a hazardous weather outlook for north and central Georgia, warning that while actual air temperatures will hover around 91°F to 93°F, the high moisture content in the air will make it feel as hot as 102°F during the peak hours of Saturday and Sunday afternoon.

Inside the jail’s oldest housing towers, internal temperatures reportedly soared past 90 degrees, prompting emergency mitigation efforts from the Sheriff’s Office and sharp condemnation from local advocacy groups.

The rainfall recharged topsoil moisture, greened up parched lawns, and provided meaningful relief to farmers in south Georgia who had been drawing heavily on irrigation wells.
