September through November brings what is known to storm chasers as the second season or the fall season. This period can sometimes see a secondary peak of severe weather as the jet stream makes its move back south in preparation for the winter months.
This dramatic changing of the seasons can oftentimes result in big cold fronts crashing south bringing the rise of conditions favorable for severe weather events. As the charts above show, a large portion of the country can expect at least some tornado risk throughout the fall months with the threat moving relatively to the south and east as the weeks pass by.
It must be stressed though: the fall peak is usually less robust than the Spring peak. …Usually. Yeah.
This isn’t always the case though, as sometimes you get big severe weather events during the Fall months. Check out one of those events in a storm chase case video about the November 16, 2015 tornado outbreak on the High Plains here:
As we always say: storm season never ends, it just hibernates.
