A Dense Fog Advisory is in effect early Sunday for Chattooga County and surrounding counties across Northwest Georgia as widespread patchy dense fog reduces visibility in many areas. Patchy dense fog is expected between 4 a.m. and 10 a.m. Sunday, with the thickest fog producing visibility as low as one-quarter mile or less.

Drivers are urged to use caution on area roads, especially in low-lying spots and near waterways. Slow down, use low-beam headlights, and allow extra distance between vehicles.

Fog should gradually lift by mid-morning, improving travel conditions and giving way to mostly clear skies for Sunday afternoon and evening with light winds. High temperatures today are expected to reach the low 60s, then fall to the low 40s overnight.

Mild and mostly dry weather is expected to continue into Monday as high pressure settles in. Highs are forecast to reach the low 60s again, with a weak, dry disturbance possibly bringing some increased cloud cover Monday morning into the afternoon.

Looking ahead through the week, forecasters expect an unusually warm pattern to set up across Chattooga County and Northwest Georgia, with temperatures running well above normal — generally 15 to 20+ degrees above average. Highs could reach around 70 degrees across parts of the region during the first half of the week as ridging across the Gulf states influences local weather.

A weak system passing to the north late Tuesday may slightly weaken the ridge and could trigger a few spotty showers, but rainfall amounts are expected to be light and scattered due to weak forcing.

The next better opportunity for rain arrives late week into the weekend (Friday through Saturday) as the ridge shifts east and a western trough approaches. While nothing is definitive yet, the developing pattern is one to monitor because it could support a severe weather setup if storms organize and timing lines up with daytime heating. Forecast signals suggest dewpoints near 60 and temperatures in the 70s could provide enough moisture and energy for thunderstorms. Any stronger line of storms would still depend on how the system evolves, and confidence remains low at this time.
