Snowflakes don’t matter, but another killing freeze does

Yesterday a spot or two around Atlanta saw a few flurries briefly, and again today a few snow flakes have been seen even in the metro area, mixed simultaneously with big patches of blue sky.

This is being caused by the cold air advection (CAA) stratocumulus clouds, as channeled vorticity in the Northwest to Southeast jet stream flow squeezes out what little moisture is left in the air mass.

You can see those cloud streaks/streets clearly on the visible GOES Satellite image:

Sunshine will increase as the day wears on, and most of us will not see any flurries and for those that do it will not last nor matter.

This is a VERY COMMON phenomenon whenever Atlanta gets a serious cold snap. I ‘ve been an eye-witness at my home in Kennesaw, where it happens at least once almost every winter.

HERE IS THE NATIONAL SNOW COVER AS OF THIS MORNING:

By the way, the latest official snowfall in Atlanta was 8 inches on March 24, 1983.

Another Freeze Warning tonight, as cold or colder than last night. The killing freeze this morning and again tomorrow morning bad enough to damage sensitive early blooming plants and crops.

Take precautions to protect plants, pets, pipes, people and vehicles.

Wind chill factor tomorrow at the school bus stop in the upper teens to low 20s again.

Record low for Atlanta is 20 set in 1993 so that looks safe . Record lows (circled) in south Georgia and deep into Florida:
