Wow thanks I am saving this. This is one of my very first weather memories. I have very dim memories of the late 70s and early 80s.....like a dim memory of the Feb 1978 blizzard from when I was 4 what I remember is giant icicles hanging outside the window, from the Christmas 1980 arctic outbreak, very windy conditions and brutal cold, and then it's the January 1982 snowstorm with the plane going down in the Potomac and then the epic April 1982 blizzard and another snow event a week later. My next big memory after that is the February 1983 blizzard and then more regular memories after that (next one after that is Hurricane Gloria but I was already in 7th grade in September 1985 so the memories are more continuous by then.)
So -9 was the low there on Christmas and 1" of new snow!
I wonder if this is the lowest temperature at which 1.0" or more of snow has fallen in our region (although I'm sure it was snowing when it was warmer than that-- just after the arctic front moved in?)
