December Blows In

The storm that dumped 5-15″ of snow in the Chicago area pumped some record setting warmth up the eastern seaboard. A sampling of the December 1st records that fell on Friday:

BWI-Marshall: 75, old record= 73 in 2001
Reagan National: 75, old record= 71 in 2001
Dulles Airport: 75, old record= 72 in 2001
Salisbury: 73, old record= 72 in 2001
Richmond: 77, old record= 74 in 2001

The 75 at BWI-Marshall just missed the all-time warmest for December, which is 77 set on 3 occasions: December 6th and December 7th of 1998 and December 29th of 1984.

Big changes are on the way for the weekend and into next week. A cold front swept through with wind gusts to 40mph at BWI-Marshall and 53 mph at Dulles, and that front continues to move farther off the coast. As of 10:00 p.m. Friday evening, temperatures have already fallen nearly 30 degrees from those balmy record highs!

When the cold air settles in we’ll have to keep an eye on the coast. Computer models are indicating an area of low pressure will form near the South Carolina coast Sunday afternoon and track toward the outer banks late Sunday. This storm could brush the lower eastern shore of Maryland with a chilly rain. If it moves a little farther west, parts of the eastern shore or even central Maryland would have a chance for a little wet snow, sleet or cold rain Sunday night into Monday morning. As of Friday evening our in-house computer model runs are showing the storm remaining far enough off shore to miss the Baltimore metro area, but this storm will have to be watched over the weekend.
