Believe it or not, across the southeast there is some potential for thunderstorms and even “thundersnow” (lightning and thunder while snowing … here’s an article on it) as these air masses collide.

  1. Your report is as always full and understandable. Best in the world.
    It would be a nice treat if you could arrange a gentle snow, maybe an inch, with no
    ice. Kids here grow up never seeing snow. I’m from Beaufort…and had to go to
    college to see more than a touch of snow.
    Thanks…Arnold Young

  2. I have only experienced thundersnow twice, both times when I lived in north Atlanta. It was confusing at first, but pretty cool.

  3. My daughter and family live in Richmond VA and your forecasts were completely accurate about their area
