Northwest Georgia will experience another hot day today before showers and thunderstorms become more widespread later this week.

Today will be mostly sunny with a high near 94 degrees. Heat index values could reach 100 during the afternoon. Winds will be calm early before becoming southerly at around 5 mph. Tonight will be mostly cloudy with a low near 75.

A cold front approaching from the north will bring a return to more active weather on Wednesday. The day will be partly sunny with a high near 91 and heat index values again approaching 100. There is a 30 percent chance of showers and thunderstorms, mainly after 5 p.m.

Rain and storm chances increase to 60 percent Wednesday night as the front settles into north Georgia. Some storms could produce heavy rainfall, frequent lightning and strong wind gusts. Localized flash flooding could become a concern where storms repeatedly move across the same areas.

Temperatures will become slightly cooler Thursday and Friday, with highs in the middle to upper 80s. Scattered showers and thunderstorms will remain possible both days.

Saturday currently has the highest chance of rain, with showers and thunderstorms likely and a 70 percent chance of precipitation. Highs will remain in the upper 80s before warming back to around 90 Sunday and the lower 90s by Monday.

Tropical Storm Bertha will continue moving slowly westward across the northern Gulf of Mexico. The storm is not expected to bring any direct impacts to Northwest Georgia, though increasing moisture and the approaching front will contribute to higher rain chances later this week.
