Oh the weather outside is frightful etc. A little holiday music to start us off on this snowy forecast as we await our first measurable snow of the season!!!
1. The models have had an interesting turn for the weekend going from only a light snowfall to now a decent snow event or two this weekend.
2. Highs should be near 40 Thursday and Friday across the mid south with increasing clouds Friday.
3. Friday afternoon rain should develop and change to snow quickly Friday evening in response to a low moving up the east coast and a strengthening upper level disturbance moving from the plains across the lower Ohio valley. The upper level disturbance will continue the likely chances for snow through Saturday. Right now I see the potential for a 1-3 inch snow across the mid-south. This could create some slick spots and travel issues with temps near or below freezing. GFS model image for sat am 850 mb temps, GFS image of upper level disturbance 500 mb over northern Tenn sat am.
4. Sunday should be sunny in the day though a clipper system will dive into the region with clouds and a band of snow Sunday night. With nw flow continuing highs should only be near 30 and lows near 20 Sunday night which also may lead to higher snow ratios perhaps closing in on 15:1. With that factored in we may see another inch or so across the mid south Sunday night. GFS image of Sun night clipper and surface temps.
5. Heading toward Christmas another system should be moving the region leaving open the potential of a white Christmas.
6. I’ll be doing the majority of posts between now and the end of winter break which is the end of January. This site will be updated about 3 times a week with bonus comments. However Christmas week may only feature two updates at the start of the week.
