As April arrives, the severe weather season intensifies in the South, with the jet stream and interacting air masses creating an environment ripe for tornado development. While April may see the most tornadic activity on average, March, May, and June also see significant storm activity.

Why it matters

Tornado season poses a serious threat to communities in the South, with the potential for widespread damage, power outages, and loss of life. Understanding the meteorological factors that drive this seasonal spike in severe weather is crucial for residents to stay prepared and take appropriate safety precautions.

The details

The jet stream, a high-altitude conveyor belt of fast-moving air, plays a key role in April's tornado activity. As the jet stream travels northward during the spring months, it allows warmer air from the Gulf to advance northward, creating an unstable environment. When a low-pressure system develops, the interaction between the warm, moist air and the cold, dry air behind the system leads to the formation of severe storms and tornadoes.

• April marks the peak of tornado season in the South.
• March, May, and June also see significant tornado activity.
• In 2025, March and April were the most active months for tornadoes.

What’s next

Residents in the South should stay vigilant and monitor weather forecasts closely throughout the spring months, as the potential for severe storms and tornadoes remains high.
