Severe weather is a possibility around the Southeast in any month of the year, but April is right in the middle of the climatologically most-favored time period for large-scale severe weather and tornado outbreaks. 

In recent memory, the April 2011 outbreaks are still fresh in the minds of many. April 16, 2011 produced the greatest number of tornadoes on record in a single day in North Carolina. That was followed only 11 days later by one of the worst, largest, and most tragic tornado outbreaks in the nation's history: the April 27, 2011 outbreak. 

In general, April marks the time of the year when the warm, moist, and unstable air from an increasingly warm Gulf of Mexico has some of its most intense battles with shots of cold, dry, arctic air that are still trying to make a push southward across the Lower 48. 

The polar branch of the jet stream is still fairly active, but it will weaken and retreat northward to its typical high-latitude summer locations into May and June. As that polar branch of the jet stream, along with its embedded disturbances, interact with the warm and moist air from the Gulf of Mexico, April marks prime tornado season for much of the Deep South and Carolinas. It spreads westward into the Plains and Midwest with time.

Below are the severe weather probabilities, based on a 30-year climate average, for April 1, April 15, and April 30.

Later, into May and June, the greater historical odds will continue to develop farther north and west through the Plains and Midwest states as the polar jet continues it northward trek. 

While tornadoes can happen during any month of the year, for the Deep South and Carolinas, April is the heart of the season that can produce severe weather outbreaks and tornadoes.
