The week of December 21, 2014, could be problematic for some travelers as winter weather moves out of the west and through the Plains states and into the east. Although not a severe storm, precipitation could bring travel delays, with the heaviest downfall in eastern Plains and Great Lakes region. The good news: those wishing for one have a good chance of seeing a white Christmas across much of the country’s northern latitudes.

More southern latitudes will see rain or a rain-snow mix, and the southeastern United States will be wet both pre- and post-Christmas.

If you’re looking for sunny skies, the southwest and southern and central California will be precipitation-free.
