Overnight, two quick rounds of snow – mixed with some sleet and snow pellets – deposited a quick coating to a couple inches across the Washington and Baltimore metro regions.
The heaviest amounts fell in D.C.’s northern suburbs (up to 2-2.5 inches in northern Maryland), with little or no snow to the south and southwest.
Officially, Reagan National Airport picked up 0.3″, Dulles 0.5″, and BWI 0.9″.
Our forecast of a coating to a few inches was in the ballpark in most areas – though snow totals tended towards the low end of our projected ranges (which we noted would likely be the case in a 9 p.m. update). We correctly predicted the heaviest snow would fall north of the District. Generally, somewhat less snow than forecast fell west and southwest of the District, with amounts falling in our “bust” range.
Overall, we accurately captured the overall timing of the event and its impacts.
Storms which track north of D.C. rarely put down big snow amounts, and this system was another example of that.
Overall, I’d give us a B grade for this event.
