( – It may sound surprising, but tornadoes in November are actually not all that uncommon. The month has averaged 54 tornadoes per year during the 20-year period ending in 2014, but as many as 150 tornadoes have occurred in two separate years, 2004 and 2005.

According to our severe weather expert Dr. Greg Forbes, the second half of October, and especially November, can often be a second season for tornadoes and severe thunderstorms.

“In many ways, this is the counterpart to spring, when strong fronts and upper-air systems march across the United States,” Forbes said.

“When enough warm, moist air accompanies these weather systems, the unstable conditions yield severe thunderstorms and sometimes tornadoes.”
