There was a storm like this back in February sometime in the early 90s. It was supposed to just be a frontal passage with rain changing to snow and ending, well it ended up snowing all day with temps of between 33-34 and it only stuck on grass but then it snowed all night too and got heavier and we got 8 inches in a narrow band from Newark to NYC through Long Island and it snowed for 36 hours straight! One of my all time favorite storms and a complete surprise, as no accumulation was expected. A low formed along the front and stalled SE of the Hamptons.
