The reason why tornadoes are more common in spring compared to other months is because the required atmospheric ingredients come together more often this time of year. Tornado outbreaks occur when a storm system propelled by a strong, southward dip in the jet stream punches into the Plains, Midwest or South.
Why do tornadoes happen more in the summer?
Any time there is a surge in temperature and humidity levels, combined with the approach of cooler and drier air thunderstorms can erupt. The most dramatic time of the year for this is in the spring to early summer. “Traditionally, severe weather and tornado season peak from April through June,” Edwards said.
Why is tornado season in spring?
This is due to the jet stream migrating northward, along with ample moisture surging farther north at times. Warm, humid air then combines with jet stream winds that are still strong as spring begins. Tornadoes typically form during March from the Southern Plains into the Ohio Valley and Deep South.

That’s four times as many twisters as the rest of the world combined. The Great Plains are home to Tornado Alley where winds from the Gulf of Mexico and the Rocky Mountains come together to create the perfect conditions for making twisters right in the middle of America.
Why does severe weather happen in spring?
Spring is the time of year when many things change—including the weather. … Thunderstorms cause most of the severe spring weather. They can bring lightning, tornadoes, and flooding. Whenever warm, moist air collides with cool, dry air, thunderstorms can occur.
How are tornadoes formed?
The Short Answer: A tornado forms from a large thunderstorm. Inside thunderclouds, warm, humid air rises, while cool air falls–along with rain or hail. These conditions can cause spinning air currents inside the cloud.
Why does may have the most tornadoes?
In May, as the temperatures rise, the collision of that air moves north into the Plains states of the central U.S. The area that sees the most activity in May has popularly become known as “tornado alley.” During this period, most active areas are north Texas, Oklahoma, and Kansas.
