A late-season heat-wave from the 15th to the 17th produced mid-summer heat across New England on this date in 1939. East Barnet, VT was baked by afternoon temperatures of 96, St. Johnsbury topped out at 95, while Burlington’s record of 92 is also the latest it has reached 90 degrees there. In spite of such late-season heat, the following winter was cold and snowy.
