Residents across Northwest Georgia are advised to prepare for scattered to numerous thunderstorms expected this afternoon and evening. Forecasters warn that some of these storms may produce damaging wind gusts, heavy rainfall, and frequent lightning. The severe weather threat comes as the region is experiencing sweltering conditions, with heat index values expected to reach as high as 102 degrees Fahrenheit today.

The National Weather Service forecasts a 40 percent chance of showers and thunderstorms, mainly after 2 p.m. today. The primary concerns from these storms include localized damaging wind gusts that could bring down trees or power lines, periods of heavy rainfall leading to localized flooding, and frequent cloud-to-ground lightning.

The combination of high temperatures, with a forecast high near 93 degrees, and extreme humidity will push heat index values into the triple digits, making outdoor activities dangerous. Patchy fog was also reported this morning between 7 a.m. and 8 a.m. Winds today will be calm, becoming north around 5 mph in the afternoon.

Looking ahead, the chance of showers and thunderstorms tonight drops to 30 percent, primarily before 8 p.m., under partly cloudy skies with a low around 73 degrees.

The pattern of afternoon and evening thunderstorms is expected to persist through Wednesday and Thursday. On both days, there’s a 40 percent chance of storms after 2 p.m., with highs around 91 degrees. Overnight lows will be in the low 70s. Winds will generally remain light, around 5 mph.

Residents are urged to take precautions against the heat, including drinking plenty of fluids, staying in air-conditioned rooms, staying out of the sun, and checking on relatives and neighbors. During thunderstorms, remember the phrase “When thunder roars, go indoors” and avoid seeking shelter under trees. Never drive through flooded roads.
