In fact, Alex Sosnowski, Expert Senior Meteorologist for AccuWeather.com, says there is a secondary severe weather season that occurs during October and November, which favors the Deep South. The primary season, nationwide, is in the spring. (See link below.)
While rare, he adds, tornadoes reaching as far north as the Midwest and mid-Atlantic are not unheard of during November. Occasionally, a small number of the tornadoes can be rather strong.
In the last 40 years, northeast Georgia and other parts of the Deep South have been struck by late-season tornadoes at least twice.
