Fort Belvoir low of 15. Surprised how low that station gets being close to river and often colder than IAD. Open field/lack of surrounding concrete perhaps?
BWI: 5.3
DCA: 1.3
IAD: 7.2
RIC: 6.4
SBY: 4.6
Methodology: Fringed by several Miller B's and one southern slider + one fantastic storm track but BL temp issues = minimal accumulation
Agree with weighing seasonal trends. This is looking very familiar to the 1st storm of the winter (way back in mid-December) for my backyard. 1-2 inches of snow then a mess. Probably less rain this time which would be an improvement.
