Illinois, Indiana face Level 4 of 5 severe storm risk Wednesday; strong tornadoes possible
CHICAGO - Severe storms are set to slam portions of the Midwest and Northeast through Wednesday, raising concerns for another major outbreak coming just days after tornadoes, destructive winds and large hail battered many of the same areas.
This pattern isn’t unusual for Illinois, which has led the nation in tornado reports, with more expected this week.

FOX Chicago's Mike Caplan breaks down why he thinks Illinois has been seeing so many tornadoes in recent years.
Severe weather will begin Tuesday in Illinois, Indiana and Michigan, sparking thunderstorms with gusty winds and hail. However, an isolated tornado cannot be ruled out, the FOX Forecast Center said.
With that, the Storm Prediction Center has issued a Level 2 out of 5 risk for areas in the Midwest, including the metros of Chicago, Indianapolis and Detroit.

According to the FOX Forecast Center, a strong area of low pressure is expected to develop across parts of the Plains on Tuesday and race eastward.
Ahead of it, a strong upper-level jet stream will drive southerly winds, pulling Gulf moisture northward to interact with a cold front—setting the stage for severe weather.
By Wednesday, the severe weather threat will increase as the area of low pressure moves from the Midwest into the Great Lakes.
Ahead of the risks, a Level 4 out of 5 severe storm threat was added Tuesday morning for areas across north-central Illinois and western Indiana.

Meanwhile, a Level 3 out of 5 severe storm risk has been issued from Kansas City to St. Louis, and northward into Chicago, with a broader Level 2 threat stretching from Kansas to Kentucky, including Louisville, Indianapolis, and Columbus.
The FOX Forecast Center said there could be two distinct rounds of severe storms: One in the morning to afternoon hours bringing damaging winds and large hail, followed by a second round as atmospheric conditions rapidly destabilize by Wednesday afternoon.
With a significant amount of wind shear in place, discrete supercells capable of producing intense, long-track tornadoes are expected to develop initially.

Through the evening hours, these storms will develop into an intense line of severe storms bringing a widespread threat of destructive, straight-line winds through the region.
A flash flood threat is in place across the Midwest as storms move through. Since much of this area is already saturated from previous weeks of storms, it will take only some additional rainfall to spark flash flooding.

The FOX Forecast Center said widespread rainfall totals of 1 to 2 inches are expected across Wisconsin, Illinois, Michigan, and Indiana, with localized amounts exceeding 2 to 3 inches.
