Millions of Americans are under tornado watches as potent storms traverse the Midwest on Thursday. The National Weather Service (NWS) has issued alerts for dozens of counties across Illinois, Iowa, and Missouri, effective until 3 p.m. CT.
The Chicago metropolitan area is identified as a focal point of the potential threat. Meteorologists note that while tornadoes are relatively infrequent in this region, severe weather outbreaks have become more common in recent years. AccuWeather Expert Meteorologist Brandon Buckingham stated that the necessary conditions for severe thunderstorms are aligned across the Plains and Midwest for a significant outbreak.
Abundant moisture, an unstable atmosphere, and strong storm systems emerging from the Rocky Mountains are expected to fuel widespread thunderstorms. These storms could generate wind gusts approaching 100 mph, softball-sized hail, and numerous tornadoes, potentially leading to hundreds of severe weather reports.
AccuWeather is advising residents to prepare a tornado safety plan, identifying interior, ground-floor locations away from windows, such as bathrooms or basements, as safe spaces. They also recommend keeping an emergency kit and sturdy shoes readily accessible for navigating post-storm debris and potential power outages.
The NWS alert encompasses a heavily populated region of the Midwest, including cities like Chicago, Rockford, and Peoria in Illinois; Milwaukee and Madison in Wisconsin; Grand Rapids and Kalamazoo in Michigan; Burlington, Dubuque, and Davenport in Iowa; and South Bend, Indiana. Widespread severe weather is anticipated within this zone.
Individuals outdoors are urged to seek shelter in enclosed buildings and avoid standing under trees, as high winds could cause them to fall unexpectedly. The storms also carry the risk of causing widespread power outages.
While the current tornado watch is limited to three states, the risk of severe weather extends over a broader area, potentially impacting nearly 50 million people from southern Canada down to Texas, and including parts of Michigan and Ontario.
Separately, a storm system moving toward the East Coast may cause flight delays and cancellations. AccuWeather warned that torrential downpours could reduce visibility for drivers and lead to flash flooding in urban areas, capable of swamping vehicles quickly. Thunderstorms are forecast for Thursday and Friday in parts of North Carolina, New York, and New England, with a concentrated area of greater severe weather risk likely from northern Virginia to southeastern New York and southwestern New England.
