The East and Southeast will be warming up for the Dec 27-Jan 3 period, then the pattern will again turn colder...like Keith says, winter isn't over...hell, it's only just begun. This is going to be a wild week for a lot of the nation, just not here on the East Coast.
The absolute MONSTAH storm about to slam into the West Coast is chock full of Pacific moisture, and when all is said and done, parts of California could see 4-8", setting off mudslides. Winds (gusts) could reach hurricane force with this bad boy. Mountain areas could easily see one-two feet or more of the white stuff. That's all gonna slide eastward as the week progresses. The jet will split on Tuesday, and this storm is gonna ride the southern split all the way up into the Dakota's later in the week. This split jet will keep the cold air locked away in Canada, so there will be few areas of the country that will see any snow through the end of the week.
Look for cold to begin returning to the nation's heartland towards the end of the week as another vat of cold will be poised to spill out of Canada and we start the warm-cold-warm-cold pattern all over again.
