Rain and brisk winds swept into metro Atlanta at mid-day Monday, threatening a messy afternoon commute.

Parts of west Georgia, meanwhile, were under a severe thunderstorm warning as a cluster of strong storms moved into the state from Alabama.

The storm warning was posted just before noon Monday for Haralson and Carroll counties.

Several metro Atlanta counties were also under a significant weather advisory for the risk of brief, weak tornadoes as storms approached.

Counties under that advisory included Cobb, Cherokee, Forsyth, Gwinnett, Douglas, Coweta, Fulton and DeKalb.

A half-inch of rain had already fallen in west Cobb County by 12:30 p.m., while just west in Paulding County, the rainfall total was .79 inch south of Dallas.

Rain should continue through late afternoon, which could mean wet roads for the drive home Monday afternoon, said Channel 2 Action News meteorologist Karen Minton. Skies should begin clearing after 8 p.m., Minton said.

Monday’s high should reach the mid- to upper 60s, but cooler weather is just around the corner.

“The cold front should start pushing into Georgia around noon today with rain just ahead of it,” Minton said Monday morning. “Rain can pop up at any time ahead of the front, but metro Atlanta will get the rain and cold front starting on the northwest side moving in to Atlanta from noon through early evening” she said.

On Tuesday, much colder weather will arrive, Minton said. “Lows will drop to the 30s in the morning, and stay in the 50s during the day for the rest of the week,” she said.

The Georgia mountains are under a wind advisory until 7 p.m. with gusts to 40 mph possible above 1,500 feet.

Monday’s rain won’t put much of a dent in the rainfall deficit, which is more than 15 inches so far this year.

Area lakes could use the rain as well. Lakes Lanier and Allatoona are more than 14 feet below full pool.
