Winter Storm Cleon Impacts The Rockies, Upper Midwest

Update: 12/4/13. Winter Storm Cleon is currently disturbing parts of the northern Plains and Upper Midwest with a combination of significant snow, wind and bitter cold temperatures.

Northern Plains Through Upper Midwest

Lighter snow (generally 4 inches or less) from eastern North Dakota into northwest Minnesota. Heavier snow across northern/northeastern Minnesota. Duluth likely to see another foot or more (with wind gusts over 25 mph coming in from Lake Superior). Twin Cities could see up to a 4 inch event today.

Rockies

Snow from southeast Utah through Colorado to southern Wyoming. Favored ski centers could see 4″-8″ of additional snow. Wind chill down to -10 at Denver but only a couple of inches of snow is likely

Southern/Central Plains Through Ohio Valley

As cold air works its way south and east through the Plains to the Ohio Valley it will be overrun by warmer air from the south. This combination will likely produce a swath of sleet and freezing rain from central Texas through Arkansas to Ohio in the Thursday through Friday timeframe. We are still a way out on trying to time the exact location and amount of icing that could develop but icing could be significant leading to major travel delays and even power outages. Looks like sleet/snow for Oklahoma City/Tulsa Thursday and these conditions should move toward St. Louis/Indianapolis and Columbus by late Thursday night/Friday. Cities that should be on the alert for icing include Dallas, Little Rock and Memphis from late Thursday night through Friday.

Northeast

A mixture of wintry precipitation should move into parts of northwest PA/Upstate NY and northern New England Friday.
