While it doesn't look like much snow, if any, will fall this Christmas...let's take a look back at some of the biggest December 25 snows...
The largest storm on Dec. 24 or 25 was one which ended, and dropped most of its snow on, Christmas Eve in 1966. This storm was among a select group in a case study done by Paul Kocin and Louis Uccellini for their book Northeast Snowstorms. The storm center tracked from central Texas and across the Southern United States along the southern edge of an Artic high pressure dipping into the northern tier.
As the storm neared the East Coast, the center "jumped" or re-formed off the Carolina coast before rapidly deepening as it headed toward New England. Though the total in Washington was only marginally above that of Christmas Day 1962, this storm impacted a larger portion of the East Coast and dropped 6-12"+ from D.C. to New York City. Amounts near of past 2 feet were reported in parts of Pennsylvania and New York.
A more recent major snowstorm, ending Dec. 26 in 1969 dropped between a few inches and a foot or more across the area and was a "near miss" for the big cities on the East Coast. Washington recorded less than 5" on the 25th and 26th, but Dulles picked up over a foot. This storm dropped between 10" and 20" across much of western Va. through central Pa., with even more further north.
The National Weather Service has a great page it released this week summarizing weather history on Christmas in Washington. Here's the link:
