During the spring the lower atmosphere warms up faster than the upper atmosphere, and a warm lower atmosphere under a cold upper atmosphere is unstable as warm air is less dense and will tend to rise. Also during this time of year, even though the weather is warming up blasts of cold air regularly come through the U.S. These cold fronts combined with the unstable atmosphere can trigger strong thunderstorms. At the same time the jet stream, which remains strong at this time of year, provides plenty of wind shear to set these thunderstorms rotating. This rotation allows the storms to produce tornadoes.
Its because its the hot month for some places for tornadoes it also depends were you are !
Tornadoes are most likely to occur in Tennessee during the spring and early summer months, especially in April and May. These months typically have the right conditions for severe weather to form, increasing the likelihood of tornadoes.

Tornadoes are not given names like hurricanes are. However some are given informal "names" for where they hit. Hundreds of tornadoes have occurred in the past 3 weeks, and many reports are still being verified. Here are some of the towns hit by some of the most notable tornadoes. Mapleton Iowa (April 9); Merill, Wisconsin (April 10); Tushka, Oklahoma (April 14); Clinton, Mississippi (April 15); Leakesville, Mississippi (April 15); Raleigh, North Carolina (April 16); Askewville, North Carolina (April 16), Clopton, Virginia (April 16); St. Louis, Missouri (April 22); and Vilonia, Arkansas (April 25). These were the sites of only a few of the worst tornadoes. Even as I type this more tornadoes are occurring. The final count will likely be over 300.

Some of the tornadoes that hit North Carolina include the Raleigh tornado in April 2011, the Greensboro tornado in April 2018, and the Nashville-Knightdale tornado in March 2020.
In Mississippi, the month of April typically has the highest number of tornadoes. This is due to the combination of warm, moist air from the Gulf of Mexico colliding with cooler, drier air from the north, creating conditions favorable for tornado formation.
April May and June.
The United States averages about 1,250 tornadoes per year, which works out to an average of 104 tornadoes per month. However, the average number of tornadoes is not the same for each month. The months are as follows.
