How about Groundhog Day in 1976? Do you remember that. That was on a school day. Woke up to blinding heavy snow, wind gusts estimated to 40 to 60 mph (estimated as my wind instruments were frozen solid) continuous thunder and lightning, and my barometer dropping past 28.60”. No one ever talks about that one and it was not forecasted either. Low pressure unexpectedly bombed on an arctic front.
