Why is 1993 an analog for March? That was a totally historic March pattern back then and I see no parallels at all to this winter, it was an entirely, completely different climate regime back then to boot. Even assuming we “flip” in early March, you have about the first 15 days of the month, then you have to hope for a very anomalous pattern, thread the needle, to get major snowstorms along the east coast south of New England (i.e.1993), even southern New England gets shaky at that point. Post 3/15, you are really fighting climo, sun angle and length of day
