Northwest Georgia and Chattooga County residents can expect a continued stretch of summer-like weather from Sunday, September 21st, to Wednesday, September 24th, 2025. A robust high-pressure system will maintain above-average temperatures and largely keep significant rainfall at bay, though moisture from the Gulf of Mexico will contribute to noticeable humidity and bring slight chances of afternoon showers.

The region remains in the grip of a prolonged dry spell. While isolated rain chances are in the forecast, they are not expected to provide substantial relief.

Temperatures will continue to be warmer than typical for late September. Following highs in the low 90s at the start of the weekend (September 20-21), daily highs are forecast to settle into the mid-80s through the period. A gradual, subtle easing of these above-normal temperatures is anticipated to begin early in the coming week, aligning with predictions for a “warm, dry start” to the fall season in Georgia, a state where September and October are historically drier months.  Tomorrow, September 22, 2025 is the first day of autumn.
