On this date 26 years ago, in 1998, people were walking around in t-shirts as the warmest December weather of the 20th century sent thermometers into the 60s. Burlington tied its December record at 67, while St. Johnsbury and Montpelier also reached 67 to establish a new monthly record for both stations. Other December records included 65 in Massena, NY, and a toasty 73 in Concord, NH. All of these records came in the morning as a sharp cold front ended the warmth with scattered snow squalls.
