Warmer air is boosting temperatures across much of the South, but winter weather is still affecting northern parts of the U.S. Light snow and a risk of ice may create travel issues from the Ohio Valley into the Appalachians and parts of the mid-Atlantic, with additional snow and some ice possible later this week in the Northeast and New England.

A cold front is moving through the D.C. region, sending temperatures back below freezing and bringing a chance of light snow and a wintry mix early in the week.
