A dangerous weather system is unleashing severe storms across the Midwest, with forecasters warning of the potential for tornadoes, damaging winds, hail, and flash flooding from Texas to Wisconsin. Tornado watches are in effect for nearly 14 million people, and the threat is considered highest in parts of Iowa, Illinois, and Wisconsin during the late afternoon and evening hours on Friday.

Why it matters

The Midwest has already endured disastrous tornado outbreaks earlier this week, and this latest round of severe weather threatens to compound the damage and disruption to communities across the region. Extreme weather events like these are becoming more frequent and intense due to climate change, underscoring the need for improved disaster preparedness and resilience.

The details

The National Weather Service has issued tornado watches for a 220-mile-wide corridor stretching from the Des Moines area to the Madison area. All of eastern Iowa is under a tornado watch until 8 p.m. Friday, and Chicago could see damaging winds, large hail, and even tornadoes as storms develop between 5 p.m. and midnight. Several counties in Wisconsin are also under tornado watch, with the highest chance of a tornado between 4 p.m. and 8 p.m. Friday. In addition to the tornado threat, the storms are expected to bring hurricane-force wind gusts, hailstones larger than 3.5 inches in diameter, and heavy rain that could lead to flash flooding. Rivers in Michigan and Wisconsin have already reached record flood levels.
