Wintry February 19-21, 2020 Winter Storm

For you guys worried about timing (when is it going to end), the HRRR should be pretty good for that. The only thing you need to remember is, if it shows the back edge over MBY at 00Z, It could have actually ended up to an hour before that point in time.

I ended up with very light snow for about an hour. Did not even dampen the deck. You guys enjoy!!!!
 
Apparantly there is a low chance of lake-effect snow in the Atlanta metro area.

...Black Ice Possible Overnight...

Across the far northern tier including Dade, Walker, Catoosa, and
Whitfield, a transition to a mix of rain and snow remains possible
before the precipitation exits late this afternoon. Initially
temperatures will be too warm for any accumulations except the
highest peaks where a dusting to up to a half an inch is possible.

Colder air will rush in behind the precipitation with temperatures
dropping below freezing shortly after midnight for the far
northern sections and the Atlanta metro sections a few hours
later. Winds will aid in drying roads but any residual water on
area roadways could result in black ice. With the abundant
rainfall over the last few weeks, there will be a higher than
normal chance of black ice conditions especially where water flows
through the higher elevations and across roadways. This will
create hazardous driving conditions where it does occur through
the rush hour Friday morning. Temperatures are expected to rise
above freezing after 10AM for most areas.

Finally, there are a few weather model solutions that suggest some
light snow is possible overnight in the Atlanta metro due to cold
air rushing over the warmer Lake Lanier. There is low chance of
this occurring and any accumulations if at all would be very
light.
