April, May and June may be known as “tornado season,” but there’s a second, smaller peak in tornadoes for states across the Gulf Coast and Deep South driven by the clash of warm, moist air from the Gulf and strong cold fronts dragging dry air southward from Canada.

Tornado activity in the United States is not limited to the well-known spring season. A second, smaller peak in tornadoes occurs during the later months of the year, particularly in October, November, and December. This secondary season primarily affects states along the Gulf Coast and Deep South, including Texas, Louisiana, Alabama, and Mississippi.

The late-year tornado activity is fueled by the interaction between warm, moist air moving north from the Gulf of Mexico and strong, cold fronts sweeping down from Canada. When these air masses collide, they can generate severe thunderstorms and tornadoes, especially when a strong jet stream is present to sustain the storms.

There’s a second, mini tornado season late in the year

So really there are kind of two tornado seasons. There's the classic one we think of, April, May, into June, but there's a second peak in tornadoes that comes later in the year, talking October, November, and December, for a few states mostly across the Gulf Coast and deep south. Really Texas, Louisiana, Alabama, and Mississippi. Those states where there's a lot of access to warm, moist air from the Gulf. That warm, moist air from the Gulf starts to kind of funnel northward, but then you have these strong, cold fronts with very cold air from Canada sweeping across the country. So when you have that clash of cold air and warm, moist air, that can fuel convective activity and severe thunderstorms. And then when you have a jet stream that's very strong across the region, and that's talking about that upper level, very fast-moving river of air, that can allow storms to survive for longer amounts of time and to potentially be even more catastrophic or severe.
