A heat advisory is in effect today for some Georgia counties.
The National Weather Service in Tallahassee says today through Friday will offer record or near-record triple digit heat. Thursday will generally be the hottest day, and the highest heat index values will occur Friday.
Today will be the first day of three days with 100-plus degree heat. The forecast high of 104 for Tallahassee on Thursday is just one degree from the all-time record high.
In most places through Thursday, the air will be dry enough to preclude a boost from heat index. Nonetheless, air temperatures this hot will pose the risk of heat-related illness.
According to the NWS, high fire danger conditions are expected to develop under full sunshine, scorching heat, and unseasonably dry relative humidity. Dead fuels will dry quickly, while live fuels will become stressed and wilty. If wildfires develop, the atmosphere will certainly support active fire behavior.
The initial return of thunderstorms is expected late Friday, at first mainly east of a Tallahassee-Albany line. The first thunderstorms on the back edge of the hot, dry air mass will come with strong and possibly severe wind gusts.
