The second hot May in a row was setting records on this date in 1978. Burlington reached 89 or better from the 26th through the end of the month, including records of 92 on the 28th and 89 on the 29th. Chelsea topped out at 93, while Rochester hit 91 degrees. The winter had been a hard one, and Mt. Mansfield had 100 inches of snow to start May, and still 2 feet at the beginning of this heat wave. By the 31st, it was all gone.
