Snow not likely Tuesday night

Snow flurries* are possible Tuesday night to sunrise Wednesday, possible but not likely.

At least no significant accumulation is expected for THE METRO ATLANTA area, some accumulation for the mountains.

We may see flakes falling in some areas mainly north of Hartsfield but not accumulating thanks to such light amounts.

At least that’s the way it looks to me as of this posting.

There is NOT a winter storm, just an arctic cold front coming:

The “Skew-T” thermodynamic diagram forecast chart below shows very little moisture and very limited lift or upward motion in the atmosphere:

The light gray areas indicate something falling from the sky but not really accumulating on the ground IMO. And the majority of models that I use (not all shown) and the ensembles agree this is no big deal for Metro Atlanta.

As of now I think its more likely the ‘S’ word is removed from the forecast rather than amounts increased.

Obviously I could be wrong, things can and do change so stay up to date with my reports on the radio and online and Follow me on Twitter @MellishMeterWSB.

The TEMPERATURES are a bigger story (Wed/Thur brutal):

* PRO TIP… “snow flurries” by definition, implies either no accumulation or insignificant accumulation. Usually just passing flakes that come and go, but periodically can sometimes fall in a brief burst.
