Grew up in the upstate. We had a snow drought from the March 73 storm - 77 record January with no measurable. From 77 on, the late 70’s rocked. Otherwise, you are correct. 80/81, 83/84, 84/85, 85/86 had smaller events but measurable snow. Otherwise, the other years were epic snow years. Really started to decline in regularity after 88 IMO.
