As forecast for weeks now a chill returns to the air the next couple nights, with light frost possible the next couple mornings, mainly in the usual colder low spots in the Northern suburbs.

Long time followers on Twitter and regular readers of this blog know I’ve been warning of the potential for another significant cold snap in early March for a couple months now, thanks to non-computer model methods.

Well now the computer models are seeing it as well.

These are just snap shots from a single model for now, specific minimum temperature forecasts will be fine-tuned next week using all data as we get closer to the cold snap.

The European Ensemble model projects snow by next weekend in the North Carolina mountains, flurries not out of the question for the Georgia mountains.

I do not currently expect it for Metro Atlanta, but at this distance it’s worth keeping an eye on it for any changes.
