A white Christmas surprise? Flakes could fly along the East Coast on Thursday.
An Arctic cold front could sweep through Christmas Eve into Christmas Day.
Its beginning to look a lot like Christmas, and the atmosphere may have a holiday gift lined up for parts of the Northeast and Mid-Atlantic next week. There is a chance that parts of the East Coast could wind up with a dusting or more of snowfall right in time for Christmas.
There are indications that an Arctic cold front may swing east across the Lower 48, rendezvousing with moisture from the Gulf of Mexico by late Tuesday into Wednesday. Rain is a guarantee on the warm side of the front, but as colder air blasts east, precipitation could switch over to snow.
That means places such as Boston, New York City, Philadelphia, Baltimore and perhaps even the nations capital could enjoy some festive Christmas Eve snow though uncertainty abounds in whether the yet-to-develop storm will come to full fruition.'>>>
