After a severe weather outbreak Tuesday in the Great Plains that pounded several areas with damaging winds and large hail larger than softballs, the storm system will progress east, putting those living along and near the Mississippi River at risk for severe weather Wednesday.

Those on the northern end of the risk area, such as Iowa, Illinois, Missouri (including St. Louis), western Kentucky and western Tennessee (including Memphis) will have storms capable of producing large hail and damaging winds, and possibly a couple of tornadoes Wednesday afternoon into the evening hours. Farther south into Mississippi and northwest Arkansas, the primary threat from storms will be destructive straight line winds.

Stronger storms across the Plains are likely to produce large hail, high winds, and tornadoes.  For a more in-depth look into the causes of the outbreak, read the technical discussion below.

It’s been five years now since the largest tornado outbreak in American history began unfolding. A total of 363 tornadoes touched down between April 25 and April 28, 2011, leaving destruction across 21 states. Four tornadoes even reached EF5 strength, the strongest on the Enhanced Fujita Scale with winds greater than 200 miles per hour.

MORECAST meteorologists recap what remains the deadliest outbreak since 1925, as well as some of science behind what caused it.
