A vigorous storm system that has produced tornadoes in the Midwest will move through New England late Sunday night into Monday morning. Tornadoes are not a threat for Southern New England, but the potential exists for damaging wind gusts in any heavy showers early Monday morning. The Storm Prediction Center has placed Southeastern New England in a 15% risk of severe weather – primarily strong winds of 58 mph or greater. The primary storm threat is from 5 am to 11 am from west to east in New England.
