Heavy rain likely by Thursday night, slight chance of weekend snow

A low-pressure system developing in the Gulf of Mexico will bring heavy rain to metro Atlanta by late in the day on Thursday, the National Weather Service said.

Forecasters are predicting  1 to 3 inches of rain through Friday, with isolated higher amounts possible. The Weather Service warned that the heavy rain could result in "widespread minor to isolated moderate flooding across the area."

The rain could begin as a wintry mix of precipitation in extreme north Georgia on Thursday, the Weather Service said.

There's also a chance in the far northern counties for a freezing rain/drizzle mix Friday night, and there could be a few snow flurries as far south as the northern suburbs of Atlanta as the precipitation ends Saturday night.

The forecast for metro Atlanta calls for sunny skies today, with highs in the mid-50s, followed by overnight lows in the low 30s.

A slight chance of rain is forecast for Thursday morning, increasing to 70 percent during the afternoon, when highs will be in the upper 40s.

The chance of rain is near 100 percent Thursday night and 90 percent on Friday, along with lows in the mid-30s and highs in the low 40s.

Friday night will be mostly cloudy, with a 40 percent chance of rain and lows again in the mid-30s.

Partly sunny skies are forecast for Saturday, with a 20 percent chance of rain and highs in the upper 40s.

Saturday night will be mostly cloudy, with a 20 percent chance of rain and snow showers and lows in the upper 20s.

Sunday and Monday will be mostly sunny, but there's a 30 percent chance of rain or snow Monday night, when lows will dip to near 30 degrees, forecasters said.
