Good evening Tennessee Valley and a very happy Monday! An exceptionally warm day across the Tennessee Valley with most folks finishing in the mid and upper 50s. It almost comes as a shock that we now turn our attention to winter precipitation.
A cold front is drawing ever closer to the Tennessee Valley with the parent low sitting well to our north over the Great Lakes. This cold front will move through during the late evening and early overnight first bringing a few rain showers, but then bringing a quick transition to snow. That transition will occur as some much colder air filters in behind the cold front. I expect the first folks to see snow will be those across NW Alabama and that could happen anywhere between 11:00 PM and 1:00 AM. From there snow will encompass the entire Tennessee Valley before exiting the area late in the morning.
Behind the snow the sun will actually make a return and we’ll see mostly sunny skies through the rest of the afternoon. That will be good and bad all at the same time. The good will come where the snow will begin to melt despite the fact that we will not be above freezing on Tuesday. The bad because the snow that melted Tuesday afternoon will refreeze Tuesday night as temperatures plummet into the teens and 20s overnight. I believe this could make for a messy commute Wednesday morning as well.
