Monday is going to be the transition day between the warm air that we had today in the 60s, to the winter storm moving in Tuesday. We will have a good coverage of clouds Monday with highs up to 49. The moisture begins to move in overnight Monday into Tuesday morning. That will come in as snow and a rain/snow mix depending on your location.
The Winter Storm Watch has now been extended into Wednesday morning. There are 2 waves of moisture that we are watching moving in late Monday night into Tuesday then another one Tuesday into Wednesday. The extension of the watch includes that second wave that comes in through Wednesday morning.
We have a Winter Storm Watch in effect for North Georgia along a line from Carroll county to Fulton to DeKalb to Hall counties and all north of that line. This DOES include the cities of Atlanta. The second watch extends down into the south metro area for Tuesday night into Wednesday. See the maps for a look at the 2 watch areas for the 2 waves of moisture coming in.
For now, the models are indicating that we will start off with rain late Monday, then gradually transitioning into a rain/snow mix late Monday night into Tuesday morning. Right now, the predictions for accumulations of 3 inches or more will be more likely in the higher elevations of north Georgia. Metro Atlanta northward could see 1-2 inches of snow during the day Tuesday.

Then comes the second round. This next round will occur overnight Tuesday into Wednesday morning. This will start off as rain and transition into a mix of rain/snow/sleet.
This second punch may contain more icy conditions than snow. Temperatures Wednesday morning will start off in the upper 20s.
Because temperatures are in flux, and the models vary on timing, we will continue to update you as more information becomes available.
