Autumn is the secondary severe weather season across the United States, and AccuWeather meteorologists expect multiple rounds of damaging thunderstorms to impact millions through the end of the weekend. The risk of damaging thunderstorms will extend across part of the Atlantic Seaboard on Sunday afternoon.

The middle to late parts of autumn typically feature a strengthening jet stream, sharp temperature contrasts and surges of Gulf moisture — all classic ingredients for severe autumn weather. Upcoming surges of cold air from Canada will help to set off the storms.
