Thanks for all this information!. Nothing like true eyewitness accounting!!
I live too far east for lake effect upslope. My area is downslope for west or northwest winds. We do well with southern systems or noreaasters, being upslope for those.
My first experience with lake effect upslope was late October of 1968. I drove from a partly sunny 53 degrees at Harrisonburg to pouring snow and 26 degrees at the summit of Spruce Knob with 4 - 6 inches acc. and drifting.
Many times during the 70's and 80's, when I wanted lake effect, I drove to the state line on Rt. 250 which is the highest elevation of any primary highway in Virginia at 4332 ft.. The old timers at Monterey have told me that legend has snow flurries falling there in July many years ago. People who have never experienced lake effect snow have no idea how much difference can exist 50 or 60 miles northwest of Staunton or Harrisonburg on an invading northwest wind, especially late fall and early winter when the waters of Erie or Michigan are still warm. Truly, another world.
