A very warm spell was just ending here on the eve of the bombing of Pearl Harbor on this date in 1941. Burlington set its December record of 67 on the 5th, while St. Johnsbury was 52 on the 6th. Light rain fell, and was remembered by a local WWII veteran, who told me he ruined a new pair of shoes as he waited outside to enlist. In spite of that warmth, and even a thaw at Christmas, there was snow on the ground for Christmas Day.
