CHICAGO, IL — Monday’s severe weather threat over Ohio, Illinois, and Indiana has been bumped up to a Level 2, one step higher than the early call made the previous day. The Storm Prediction Center’s Day 3 outlook, updated August 8 at 5:04 a.m. ET, highlights the increased risk stretching across the region.
Stalled Front Expected to Touch Off Storms
The Storm Prediction Center expects a stalled front to touch off thunderstorms near northern Illinois by early afternoon Monday. With plenty of warm, humid air waiting to the south, forecasters expect those storms to organize into clusters or short lines capable of producing damaging wind gusts.
The highlighted Level 2 risk zone stretches from northern Iowa and southern Minnesota eastward across northern Illinois, northern Indiana, and northern Ohio, with a broader Level 1 risk extending from Montana through the Great Lakes region.
Risk Could Extend Into Evening Hours
If the developing storm activity holds together as it tracks eastward, forecasters say the risk could stretch into the evening hours before conditions gradually wind down. The stalled front is expected to remain the key focus for storm development throughout the day.
Threat Levels Vary Across the Region
The SPC outlook shows the highest risk category for Monday reaching Level 2 of 5, concentrated across parts of Iowa, Illinois, Indiana, and Ohio, while surrounding areas including Michigan, Wisconsin, and Missouri fall within the lower Level 1 risk category.
Residents across Ohio, Illinois, and Indiana are encouraged to monitor forecast updates as Monday approaches, given the increased severe weather threat and potential for damaging wind gusts from organized storm clusters…
