Meteorologist Mark’s Snow Scale

On This Day in Wx History

1998- An ice storm strikes much of northern Middle Tennessee and the Cumberland Plateau. Damage in some areas eclipses that from the 1994 ice storm. Warren and Coffee Counties are the hardest hit. Eighty percent of Coffee County residents are without electricity.


Yesterday’s National Temperature Extremes

High: 82° at McAllen & Pharr, Texas 

Low: -7° at Gunnison, Colorado

Today’s National Wx Hazards

Severe storms threaten the northern Gulf Coast, while wintry weather threatens areas farther north. Expect rain and snow mix for much of the Midwest, with snowfall accumulating across the Upper Midwest. In fact, heavy snow is likely for much of Minnesota and eastern South Dakota. More snow will accumulate across much of western Colorado and eastern Utah.

Tomorrow’s National Wx Hazards

Christmas Eve will be a very active weather day in the eastern US, with severe storms across the Carolinas, flooding rainfall from the Smoky Mountains to New England, and very heavy snowfall for eastern Kentucky, southwest Virginia, and West Virginia. Another area of very heavy snow can be found across the Cleveland, Ohio area (mostly lake-effect snow there). Farther west, accumulating snowfall can be expected from Tennessee to Wisconsin and Michigan, though amounts should be on the lighter side, especially into Tennessee.
