Longitude. I don’t think it’s proximity to the coast as much as proximity t the warmer lowers and mids. I measured 9 inches but 5 miles west got 14+. Conversely 5 mikes East...indeed 3 miles east got slop. This is wet snow...snow blew twice and the shoveling just now of the 2 inches since 11:30 pm was backbreaking. NAM did well. Forget snow maps..they aren’t produced by the model. However their progs for bl were pretty good.
