Mansfield sits among the wooded hills of Tolland County in eastern Connecticut, and the tornadoes that have touched the surrounding area cluster heavily in the humid heart of summer, when July and August thunderstorms turn severe.
That summer pattern has produced intense storms: on August 21, 1951, an F2 tornado carved a 43.9-mile track roughly 100 yards wide through the region, injuring 9 people, and an F3 touched down the same day, injuring 8.
Autumn has brought violent weather as well. On October 3, 1979, an F4 tornado tore an 11.3-mile path as much as 1,400 yards wide, killing 3 people, injuring 500, and causing $275 million in property damage. Decades later, on June 1, 2011, an EF3 tracked 37.58 miles with a width up to 880 yards through the region, killing 3, injuring 200, and inflicting $227.6 million in damage.
Recent seasons have stayed active in gentler form. EF0 tornadoes touched down on July 18 and November 13, 2021, and EF1 tornadoes followed on August 18 and September 13, 2023 — the November and September dates underscoring how the local tornado season can stretch well past midsummer and into the fall.
