growing up in the late 50's 60's NYC would be cold or have snow on the ground Christmas morning...1959-1963 Newark NJ had at least 2" of snow on the ground Christmas morning...then in 1964 NYC had a warm Christmas for the first time in years and it was a shock to me...it snowed 3" on Dec 20th 1964 and it looked like another white Christmas coming up...But a warm front on Christmas eve sent temperatures to near 50's by midnight and near 70 in Newark Christmas day...1965 was another warm depressing Christmas...1966 made up for the previous two years with a snowstorm Christmas eve...
