Nearby stations @dailylurkerand @MillvilleWx have correctly summarized our swamps-of-Anne-Arundel winter with scores of A and B+ respectively. But, I am going to agree with the B+, based on the lack of, (or maybe near miss), of a KU style MECS. An A grade winter requires the KU and maybe a white Christmas. 18.4" snowfall is a bit above average here.
Also, in our back yard, we had plenty of frozen waterways for most of Jan/Feb. Good indicator of true winter.
Also, not IMBY, but worthy of note, is the widespread snow deep into the Gulf states.
