This April has been active in terms of tornadoes. So far, there have been 217 tornadoes across the United States. On average, April brings around 200 tornadoes across the country.

Rainfall compared to average

With the heavy rain from the severe thunderstorms, some places for the Mid-South and Mississippi River Valley for the month of April are running over a half foot above the average for precipitation.
