The severe weather poses significant risks to millions of residents across the Midwest and Northeast. The primary threats include destructive straight-line winds, large hail, and the potential for strong, long-track tornadoes. Urban areas like Chicago and Springfield are particularly vulnerable to wind damage and power outages. Additionally, the storms could disrupt transportation and infrastructure, with localized flooding possible in areas experiencing heavy rainfall. The combination of high winds and hail also poses risks to agriculture and property.
