Much colder air across the Midwest and the Great Lakes this afternoon.
A challenging forecast lies ahead for the Tennessee Valley. Another shot of Arctic air will move in behind a cold front late Wednesday evening. Highs will return to the middle and upper 40s Wednesday afternoon.
Ahead of this front is looks like the clouds will return along with some spotty showers and perhaps some drizzle. Temperatures will remain above freezing while the rain and drizzle are falling Wednesday evening. For tonight it will remain clear and dry with lows in the middle to upper 20s.
Thursday will be partly cloudy with more clouds late in the day. A few scattered showers possible late Thursday afternoon with highs in the middle 40s. Forecast guidance is generous with a quick moisture return overnight Thursday into Friday morning. At the same time a northeast wind will continue to bring in cold air at the surface. It is now looking possible for us to see a period of light rain mixed with freezing rain and sleet in some areas of the Tennessee Valley early Friday morning.
At this point it looks like everything will change over to just rain late Friday morning. I expect more changes to the timing and the precipitation type over the coming days. Stay tuned for possible changes.
Over the weekend expect some sunshine Saturday and a few showers on Sunday with increasing clouds. Highs will be in the 40s.
Have a great night and stay warm.
