Is a storm brewing for Christmas?

Christmas is now just about a week away, and many are already thinking about holiday travel plans, as well as if it will be a white Christmas.

More importantly, however, millions will hit the roads and the skies for the Christmas holiday beginning this weekend. Any snow or rain could disrupt travel plans ahead of the holidays. That would be big news for the record-breaking 98.6 million people AAA expects to travel 50 miles or more for Christmas this year. That total is the highest ever, up four percent from last year.

This far out in the forecast there is typically a lot of uncertainty, and this case is no different.

However, forecast guidance is becoming more in sync on the overall weather pattern in place Christmas week. In short, it looks to be quite active, including a pair of storms around the Christmas holiday across the Lower 48 states. This could make for challenging travel.

Weather.com explains what we know right now.

Monday: Rain may soak parts of the East Coast from southern New England to Florida. Some snow may fall in parts of Upstate New York and northern New England. A swath of light snow may dig its way into the northern Plains and Upper Mississippi Valley, while mountain snow is expected in the northern/central Rockies and adjacent High Plains.

Tuesday: Low pressure may wrap-up in the Mississippi Valley, with snow in the Upper Midwest and possibly parts of the Plains. On the southern end of this system, rain and perhaps some thunderstorms may rumble across parts of the Lower Mississippi Valley, Gulf Coast and Southeast, including Florida. Some snow may linger in the northern Rockies, and Cascades, as more low-elevation rain soaks western Washington.

Christmas Eve: It's still roughly a week away, so pinpointed forecasts are difficult. Strong low pressure should be spinning somewhere over the Great Lakes, driving a cold front into the East Coast. For now, wind-driven snow is possible in at least the western Great Lakes, and possibly in parts of the Ohio Valley, Tennessee Valley and Appalachians. A soaking rain may move into the Northeast, including the I-95 corridor. Significant flight delays are possible in the major Northeast hubs, as well as Chicago O'Hare and Midway. Some leftover showers and storms are possible in South Florida before the cold front clears. Snow in the northern Rockies and lowering snow levels in the Pacific Northwest.

Christmas Day: Locally heavy, wind-driven snow in the lake snowbelts from the U.P. of Michigan and northern Lower Michigan to northeast Ohio, northwest Pennsylvania, western, central and Upstate New York. Snow may spread out of the northern/central Rockies into the northern Plains. Mainly dry in the southern tier of states.
