Thanks Don, did JFK also have single digit highs and below zero lows on these dates (or in 1977)?
I lived in Park Slope, Brooklyn in the 70s and early 80s up until November 1982 (I saw the April 1982 blizzard there!) and we moved to Long Island's south shore after that so I saw February 1983 there. Normally I use NYC as my "location" up through Veteran's Day 1982 (the day we moved) and JFK after that. JFK got over 20" in February 1983 (I think-- they always do better in strong el nino snowstorms-- same thing happened in PD2 and January 2016!) so that works for me!
