Even early April... it depends on what you mean by snowstorm lol.
Realistically throwing out the colder winters like 81-82 and 02-03 and 17-18 which had big snowstorms we can look at milder winters which ended with a snowfall, then there are analogs like 83-84, 89-90, 96-97, 97-98, 98-99, 99-00.
All of these had a late season snowfall after a warm February and/or March
March 1984
April 1990 (after a historically warm Mid March.)
April 1997
March 1998 (after a nearly snowless winter)
March 1999
April 2000
None of these were really big snowfalls (I think March 1998 might have been the biggest with 5 inches, so that probably represents the top end of what we can expect.) Outside of that and March 1984 (which was more of a mixed precip mess), the others were all 1-3 inches.
