A Cold, Wet Mess Followed by Light Snow
This is one of those forecasts in which you’ll find the devil in the details! There are some key things to remember up front here:
(1) This will not be a major, shut-down winter storm for the Tennessee Valley region.
(2) The majority of precipitation will fall as rain tonight through Tuesday evening; some of us will get more than 2 inches of rain.
(3) As the rain ends, it will taper off as light snow for a few hours Tuesday night through early Wednesday morning. No major accumulations are expected; however, it is certainly possible that a light dusting up to an inch of snow is possible in some of the higher terrain of Northeast and East Alabama as well as Southern Tennessee.
(4) If you are going to the Smokies or traveling to the Mid-Atlantic or points north for Thanksgiving, you will want to check conditions ahead of you. This will be much more significant up that way.
Here’s the latest RPM model guidance showing the changeover from rain to snow starting around 8 to 9 PM Tuesday in Tennessee and Northwest Alabama. This loop runs through 5 AM Wednesday:
Here’s the specific chance of getting at least one inch of snow between 6 PM Tuesday and 6 AM Wednesday and between 6 AM and 6 PM on Wednesday:
Could there be a few slick roads where heavier snow showers develop? Yes, but it will be a temporary situation early Wednesday. The ground is still warm enough that in spite of the cold air temperatures, most roads will just be wet. Under heavier snow showers, the road may temporarily get slushy or icy before 10 AM Wednesday; after that, it should melt away quickly. That would only occur in isolated spots as it looks right now!Submit Your Photo
