Spring to winter in a blink of an eye

Impactful weather today through the next 5 days, stay weather aware and expect forecast changes and updates today through next Wednesday.

Temperatures today may drop around 20 degrees in just an hour to 90 minutes as the strong cold front moves through this afternoon, falling into the 30s early this evening to a low of 28 by morning.

35 degree temperature plunge from our high today to the low tomorrow morning.

Gusty winds will make a wind chill factor in the teens and 20s tonight, and any residual moisture on the roads from runoff will freeze although the wind should dry MOST roads.

Any sleet (ice pellets) or snow flurries you may see should be meaningless for the Metro Atlanta area I-20/I-85 Northward and most of us won’t see it.

However, some minor accumulation possible in the mountains, MAYBE down to a Rome to Pickens County line.

JUST TO PLAY IT SAFE, avoid non-essential travel in Atlanta area after 8pm:

As cold as this cold snap will be, even colder air arrives Tuesday and Wednesday behind an “Alberta Clipper” system that could produce some snow flurries Tuesday or Tuesday night.

We may have trouble getting out of the 30s for highs Tue./Wed. and have lows in the teens.

The January Thaw expected to return by late month before another turn to colder possible second week of February give or take. AHH, the La Nina Pacific pattern with low solar cycle and a negative QBO, what fun.
