This will be really interesting. My guess is that when you turn on the 10PM news tonight there will be NOTHING on radar in the mid south!
However, all indications are that between midnight and sunrise the atmosphere will moisten to near 100% from around 2,000 to 10,000 ft. above the surface.
And with temps aloft warm enough to form light rain, it will fall into surface temperatures that will run from 28-31°.
This will result in freezing rain and sleet that could cause slick roads, especially bridges and overpasses.
The graphics to the right show the NAM/WRF model's precip type with yellow=freezing rain, red=sleet (PL or ice pellets), green=rain, lt. blue=snow.
As I said yesterday, the good news is that it should change to all rain during the mid morning hours with temperatures rising above freezing, alleviating road problems.
Also, the quick movement should help avoid the situation of ice bringing down trees and power lines.
The biggest impact will be slick bridges and overpasses during the early morning hours.
Now, let's watch and see if that super quick moistening of the atmosphere occurs overnight!
