We were apparently a bit more fortunate over here in the '70's irt November Snowfall. 8" Thanksgiving 1971. 2" early November '74, 4" Nov.12-13, 76. 11" (12" Pennington gap, 16" Big Stone) Nov.26,77. The '80's had no major November Snowfalls other than Higher Elevations in 1987. A few inch or less events ; 1981, 85, 87, 89.
As you alluded to, the '60's had measurable Snow nearly every November.
