Summer is the wettest season in northern New England thanks to the higher humidity available to thunderstorms. On this date in 1913 St. Johnsbury recorded its wettest 24 hours, as thunderstorms with torrential downpours filled the rain gauges with 4.99 inches of rain. The bulk of this came in just 5 hours, and no doubt caused rapid rises in rivers and streams, and road washouts, though no mention of any serious consequences was noted in the official weather records.
