Seasonably Cool Weather for Mid Week

Matt Ross @ 7:45 AM

The coldest air of the season (to date) will descend upon DC over the next several days. Temperatures will be the coldest with respect to normal since mid September with highs 5-10 averaging degrees below seasonal norms. Far western Maryland will likely see its first accumulating snowfall of the season with some flakes possible as far east as the higher elevations of the Blue Ridge tonight.

November Snow

As some colder air moves in this week, with it comes increased thoughts of snow. While we only average 0.7" of snow in November, snow isn't a terribly rare event, with measurable snow occurring about 1 in every 4 Novembers. Additionally we have had some memorable November snowstorms as outlined below.

November 24-25, 1938: This Thanksgiving storm came on the heels of a very warm November to that point. A 6-10" snowstorm with greater amounts to the north and east of town, this storm left thousands of cars stranded on the highways during holiday travel.

November 6-7, 1953: This storm, our earliest significant one on record, was a slow moving storm with near blizzard conditions in many places causing significant blowing and drifting. This was another 6-10" storm, with the greater amounts in the eastern and northern suburbs.

November 30, 1967: Just barely squeaking into the month, this storm followed a Thanksgiving period mostly with high temperatures in the 60s. This was generally an 8-12" snowfall with the greatest snows in the northern and western suburbs. In the days after the snowstorm, low temperatures plummeted into the single digits at night including Dulles Airport's earliest zero reading on record.

November 11, 1987: Many readers might remember this storm which occurred on Veteran's Day, a Wednesday that year. Catching most forecasters by surprise, heavy wet snow fell throughout the day accompanied by thunder, stranding many motorists on the beltway. A foot or more of snow fell over much of the region, especially east of town, and the 11.5" at National Airport was the biggest November snowstorm on record and November 1987, the snowiest month on record.

November 22-23, 1989: Falling the night before Thanksgiving, a general 2-4" blanketed the DC area. The morning after Thanksgiving, Dulles Airport fell to 9 degrees, the only single digit reading on record there in November. This was a precursor to a December that would be the coldest in Washington since 1876.
