The 2021 New England Tornado Outbreak was a severe weather event that produced tornadoes, hail, and high winds across the Northeast United States and Ontario. The event raised what would become the second recorded high risk of severe thunderstorms in an outlook in New England's history, the first being in 1985. Large hail up to 3.5 inches was seen as far north as Montreal, Quebec. The outbreak was one of the most violent west of the Mississippi River, as multiple intense (EF3 +) tornadoes occurred as a result of the outbreak happening in a moderately to densely populated area.
