Cloudy this afternoon with only a few glimpses of sunshine. The clouds move back in this evening ahead of our next system.
Rain lifts north tonight as a boundary sitting to our south also attempts to lift north. It’ll run into an area of high pressure that will eventually dive south and really fail to lift much further north than the Gulf Coast. Still, the rain will move in and maybe even some frozen precipitation.
By the time we get to Thursday morning we’ll be talking about widespread rain across the Tennessee Valley, but also notice that futurecast is trying to bring in a little snow. I also want you to pay close attention to the hour-by-hour. Pay close attention to the fact that our air temperature never really drops lower than the upper 30s. This will keep accumulation to an extreme minimum.
While the snow may fall it will warm before it actually makes it to the surface and transition back to rain.
If we see any accumulation (and that’s a big if) then it would occur in the higher elevations of Southern Middle Tennessee. This model does try and bring some minor accumulation as far south as Florence, or Killen but that would be on the roofs and maybe on the grass.
Driving concerns will be non-existent because pavement temperatures will remain warm in the 40s.
The aforementioned area of high pressure will usher in some very cold air to the Tennessee Valley. That shot of cold air will be aided by the clearing sky Thursday evening and through the overnight. That clearing allows radiational cooling to take hold and lows to bottom out in the mid-20s.
