First warmer then colder then... rinse repeat the roller coaster ride. Dramatic temperature drop over the weekend as first of multiple Polar air masses come down from Canada this month and next.

Coldest air of the season to date by Monday.

In the transition another big snowstorm in the Midwest to New England. Could Atlanta see a few snow flakes? Yes not out of the question but I would not hold your breath. As of now at least, it looks like even if we did it would be brief and not last or matter with no accumulation outside of NE mountains and most of us won’t see any snow.

The sharp change to sharply colder is the real story. As I’ve said repeatedly in past blogs since Fall, the prospect for snow or ice looks alive before we warm up in April. As in the rest of life, the meeting of cold and moisture is all about the timing. The pattern looks to turn ripe but we have to wait till we have an actual system to watch.
