It is looking more and more likely that the TN Valley will see the white stuff falling from the sky to start the weekend. Models are coming into agreement about more moisture to work with.
We'll start with a few sprinkles, light rain showers late in the day Friday.
As temperatures quickly bottom out in the 20s Friday evening into Saturday morning, the precipation will change over to snow flurries and snow showers.
We'll see off and on light snow showers and flurries through the Saturday morning hours.
At this time, light accumulations will be possible. Most spots will see a spotty dusting on grassy areas at best while the higher elevations and some spots in southern middle TN could see near 1 inch.
Unless something changes, no major snowfall is expected, and no widespread travel problems are expected. Some slick/slushy spots could be possible on the side roads. We will monitor road conditions very closely and provide frequent updates.
I really like this image (below) and think it accurately depicts what we'll see...This shows the Hydrometeorological Prediction Center's (HPC) probability of accumulating snow > 1 inch. Extreme NE Alabama and some of southern middle TN have about a 20-40% chance of seeing 1" of snow through Saturday afternoon.
The bigger story is most definitely the cold. We are in the mid 50s right now in Huntsville while spots in southern middle TN have already fallen into the mid 40s. Cloudy skies and breezy west winds, it will stay in the 40s all day tomorrow and Friday. Temperatures will struggle to break out of the 30s Saturday afternoon. Wind chills could be in the teens early Saturday and Sunday morning.
We'll finally rebound back into the 50s for the work week but the 60s don't look like they'll return until late next week/weekend.
