Kansas, Oklahoma, Illinois, Indiana and Wisconsin Face Marginal Severe Storm Risk Tuesday May 12 Into Wednesday May 13

KANSAS CITY, Kansas — A Marginal Risk of severe storms is in place for parts of Kansas, Oklahoma, Illinois, Indiana and Wisconsin beginning Tuesday, May 12 and running through Wednesday, May 13.

The Storm Prediction Center issued this outlook at 12:55 AM CDT on Monday, May 11, covering a corridor from southeast Kansas and far northeastern Oklahoma northeastward into northern Illinois, northwest Indiana and far southeast Wisconsin.

What Is a Marginal Risk

A Marginal Risk is the lowest level on the severe weather outlook scale. It means isolated severe storms are possible, but widespread or major severe weather outbreaks are not expected.

Residents in the highlighted zones should still monitor forecasts closely, as even isolated storms can produce damaging winds, hail or brief tornadoes.

When and Where

The outlook is valid from 12:00 PM CDT Tuesday, May 12 through 12:00 PM CDT Wednesday, May 13. The risk corridor runs from southeast Kansas and far northeastern Oklahoma northeastward into northern Illinois, northwest Indiana and far southeast Wisconsin.

Who Should Pay Attention

• Residents across southeast Kansas and far northeastern Oklahoma should be aware that storm chances increase Tuesday afternoon and evening as the threat moves northeastward.
• Northern Illinois and northwest Indiana residents fall within the highest concentration of the Marginal Risk zone and should have a weather alert plan in place before Tuesday afternoon.
• Far southeast Wisconsin is on the northern fringe of the outlook and faces the lowest storm coverage within the risk area.

What To Do Before Tuesday

Residents across all five states should take steps now ahead of this system:

• Download a weather alert app and enable severe thunderstorm and tornado notifications before Tuesday, May 12.
• Identify a safe interior room on the lowest floor of your home away from windows.
• Stay weather-aware throughout Tuesday afternoon and evening as storms may develop quickly.
