PM Update: A slick then sloppy Christmas

By Jason Samenow

Tranquil, cold conditions this evening

If you're commuting or traveling locally this evening, the weather should not impede your plans. Though clouds will gradually increase and it will be cold, no precipitation is likely until much later tonight or early tomorrow morning. Unfortunately, Christmas Day looks to be one big mess.

Through Tonight: Afternoon highs in the mid-30s will drop back below freezing after dark as clouds increase. Temperatures will bottom out in the mid-to-upper 20s before the possibility (40% chance) of some light freezing rain and drizzle towards dawn.

Christmas Day (Friday): A period of light freezing rain is likely in the morning, starting from southwest to northeast between about 5 and 9 a.m., especially in the colder north and west suburbs where it may take until noon to get above freezing. In the immediate metro area, any freezing rain should change to plain rain by mid-morning. Steadier rain is likely in the afternoon with highs in the mid-to-upper 30s. Localized flooding is possibe especially tomorrow night as rain picks up and temps rise to near 40 or into the 40s, accelerating snow melt.

Travel trouble spots: A huge storm in the Great Plains and parts of the Upper Midwest will make travel difficult or impossible today into tomorrow. Record, historic snowfall is possible from central Kansas to eastern Nebraska to the eastern Dakotas into central Minnesota with 1 to 2 feet of snow. Sound familiar?

Closer to home, travel conditions will deteriorate tomorrow, especially as you head north and west. Portions of western Virginia, western Maryland, the eastern panhandle of West Virginia, and then the interior portions of Pennsylvania and New York will be in for a long-duration ice storm.

Some areas, especially the I81 corridor could be an icy mess for at least several hrs. tomorrow.

I finally got shoveled out from 24 inches of snow last Sat.

Happy Holiday to everyone!

I'm in a good mood now... got the UPS packages in the nick of time. Brown did it for me.

Any chance of a period of snow/sleet before the freezing rain... kind of like the Dec 9th event?

Sitting at 22.8F on an east facing slope in the Blue Ridge Mtns...

Merry Christmas!

You may run into some rain, but probably not too heavy and shouldn't have any iciness to worry about on that route at that time.
