definitely cyclical because I was looking at other data from another station further away a bit, with longer data history and prior to when the one closest began recording and the almost sinewave like pattern is present, goes up comes down, and some anomalies in between, but overall, peaks and valleys, sun activity perhaps, interesting read about the winter of 55-56, where there were like three big noreasters within two weeks, that year was the biggest here with 177", I obviously didn't take that data but that began the period of over 100" winters until like 71-72 where it tapered off some, interesting stuff
