This threat comes as an active weather pattern takes hold of the Central U.S., as spring severe weather season intensifies across the Heartland following an active March which saw deadly tornadoes in Illinois, Indiana and Michigan.
Thunderstorms are expected to develop and intensify by late Thursday over the Central Plains and shift over the Midwest and Great Lakes through the afternoon and into the evening.

According to the FOX Forecast Center, damaging wind gusts of 75 mph or stronger and tornadoes are the primary severe weather hazards expected.
“Some limitations in instability may prevent storms from becoming widespread. However, storms that do form are likely to be discrete supercells, which increases the tornado threat,” the Forecast Center said.
The risk of strong (EF-2+) tornadoes spans a corridor more than 700 miles long, from Missouri to Michigan.

The Storm Prediction Center has issued a Level 3 out of 5 risk of severe thunderstorms for southern Wisconsin, just south of Milwaukee; northern Illinois, including Chicago; and eastern Iowa.
Storms are expected to form over Iowa by late Thursday morning, reaching Illinois and Wisconsin by noon and St. Louis and Chicago shortly after, with the threat lasting through the first half of the evening.

As storms weaken, heavy rain will remain, creating a localized flash flood threat late Thursday across Wisconsin, Michigan, and northern Illinois. A widespread 1-2 inches of rain is expected across the Midwest and parts of the Great Lakes through Thursday.

A second severe weather system will move out of the Rockies and into the Plains by Friday afternoon.

Parts of the Midwest are once again in the bull’s-eye, where southern Iowa and northern Missouri are under a Level 3 threat and are under the greatest threat of seeing discrete supercells capable of producing tornadoes.
Heavy rain will persist overnight Saturday, creating another flash flood threat from northern Texas into southwestern Missouri.
This active severe weather pattern comes right on cue, as April is historically when spring severe weather season begins to intensify across the middle of the country.
