A Dense Fog Advisory remains in effect until 11 a.m. Monday for parts of Northwest Georgia, including Chattooga County, with visibility falling to one-quarter mile or less in some locations.

The fog is expected to create hazardous driving conditions through the morning hours, especially on back roads and in low-lying areas. Drivers are urged to slow down, use headlights, and leave extra distance between vehicles.

After the fog lifts, the region will remain well above normal temperature-wise, with afternoon highs reaching the upper 70s and lower 80s. That spring-like warmth is expected to continue through midweek before a cold front brings cooler air later in the week.

Forecasters are also watching the potential for strong to severe thunderstorms. A round of storms is possible Monday night into early Tuesday, mainly across western Georgia, with the risk of damaging winds and small hail.

A second and potentially more widespread round of thunderstorms could develop Wednesday afternoon and continue into Thursday. At this point, far Northwest Georgia appears to have the greatest risk for stronger storms, though that could change as the system gets closer. Some areas could also see localized flash flooding where heavier rain develops.

Behind the front, cooler and drier weather is expected to move into the area by Thursday and continue into the weekend. Temperatures will drop sharply, with highs falling back into the upper 50s and lower 60s across North Georgia and overnight lows dipping into the 30s by Friday morning.

Residents in Chattooga County and across Northwest Georgia should remain weather aware through the week as conditions shift from dense fog and unusual warmth to possible severe storms and a late-week cool down.
