With the start of April also comes the start of the severe weather season.  

Leftover cold winter air dipping down from Canada clashes with warm, moist spring air moving north off the Gulf of Mexico to rev up the storms this time of year. 

The next three months account for over half of the average tornadoes reported each year in the United States.

From 1991 to 2010, on average there were 1253 tornadoes reported each year.  

April, May, and June accounts for 674 of those tornadoes. That is nearly 54% of the total.
