Winter Wx Thoughts.. Wednesday Update – 10:30pm #alwx @wvua23

Good Wednesday evening! Here’s a quick update on the winter weather threat to portions of Alabama. Before you get too excited about snow across our area, above is some of our latest computer models snow output for Tuscaloosa. The GFS is the only model at this time that has accumulating snow in Tuscaloosa. The NAM, RPM and EURO have no accumulating snow.
Aside from the GFS, some models hint at some light snow accumulations north of I-20, but little to no snow in the winter storm watch area as shown below. Counties in blue are under a winter storm watch for Friday, roughly in counties near I-20 and I-59. However, I have noticed a northward trend in the precipitation shield in the latest runs of our forecast data. If this trend continues, the risk of wintry weather will increase in areas generally near the I-20 corridor. Please understand, this is an incredible complicated setup. There is a fine line forecasting winter weather in the deep south such as where is the best uplift, cold air and moisture combination. A 50 mile error in placement of the precipitation could mean the difference between a cold/dry day and a snow storm. There is also a distinct possibility of a mixture of freezing rain and sleet for areas south of I-20 and maybe as far south as the US HWY 80 corridor. Wintry weather that falls in our area would cause some travel issues on Friday and Friday night.
I want to encourage you to keep checking back for updates on the weather blog and, on facebook & twitter and live on WVUA at 5, 6 and 10pm. This is a fluid situation and small changes could cause or prevent travel issues.
