Chattooga County and all of Northwest Georgia are currently under a Heat Advisory, effective until 8 PM this evening, as dangerously high heat index values are expected to persist through Thursday. Residents are urged to take precautions against the excessive heat.

Forecasters warn that while actual air temperatures will pull back slightly from previous days, the combination of high temperatures and oppressive dewpoints in the 70s will lead to widespread heat indices nearing 105 degrees this afternoon. These challenging conditions are forecasted to persist into Thursday.

Today’s Forecast: Today will be mostly sunny with a high near 93 degrees. However, the heat index values are expected to feel as high as 100 degrees. There is a 30 percent chance of showers and thunderstorms, mainly developing after 5 PM. Winds will remain calm.

Tonight, the chance of showers and thunderstorms continues, primarily before 11 PM, followed by a slight chance of thunderstorms after 4 AM. Patchy fog is also possible after 2 AM. Mostly cloudy skies are expected, with a low around 74 degrees. The chance of precipitation is 40 percent.

Thursday’s Outlook: Thursday will see partly sunny skies with a high near 91 degrees, but heat index values could still reach 97 degrees. Patchy fog is possible before 9 AM. Showers and thunderstorms are more likely, primarily after 4 PM, with a 60 percent chance of precipitation. New rainfall amounts are expected to be between a tenth and a quarter of an inch, with higher amounts possible in thunderstorms. Winds will be calm, becoming west around 5 mph in the afternoon.

Thursday night brings a chance of showers and thunderstorms before 11 PM, then a slight chance between 11 PM and 2 AM. Skies will be partly cloudy, with a low around 73 degrees. The chance of precipitation is 30 percent.

Friday: Severe Storm Potential: The weather pattern shifts on Friday, bringing a heightened risk of severe weather. Showers and thunderstorms are highly likely, particularly between 2 PM and 5 PM, with probabilities reaching 70 percent. Forecasters warn that these storms could become strong to severe as they develop along a slowly moving cold front expected to drape across the Southeast. The high on Friday is anticipated to be near 93 degrees.

Weekend Relief Ahead: By Saturday, the cold front is expected to stall across Middle Georgia, leading to elevated chances of afternoon precipitation in that region. However, for Northwest Georgia, the stalled front, combined with cold air damming down the Appalachians, promises a much-needed break from both storms and the oppressive heat. Cooler temperatures are anticipated for Northwest Georgia heading into the first full week of August, offering significant relief from the current heatwave.
