The National Weather Service upgraded the Nashville area's winter storm watch to a winter storm warning on Tuesday. Here's what to expect.

The National Weather Service Offices in Paducah & Louisville have much of the Tri-state under a Winter Storm Warning, meaning heavy snow is expected with a winter storm moving into the Tri-state later today into the overnight hours.

Storm conditions clear from Western Colorado this morning. Heavy snowfall fell over portions of the high country. The winter storm has moved to the eastern plains and will exit Colorado through the eastern border.
