Forecasters are warning that a severe weather outbreak is expected to impact nearly 80 million people across the central United States on Tuesday, with the potential for powerful thunderstorms, large hail, damaging winds, and possible nighttime tornadoes. The threat stretches from the southern Plains through the southern Great Lakes, including major cities like Chicago, Dallas, St. Louis, Oklahoma City, Indianapolis, and Kansas City.

Why it matters

This severe weather outbreak comes just days after tornadoes killed eight people in Oklahoma and Michigan, highlighting the ongoing threat of extreme weather events in the region. Nighttime tornadoes are particularly dangerous, being roughly twice as deadly as daytime storms, and the forecast conditions could lead to a significant severe weather event.

The details

The Storm Prediction Center has warned that the setup "could be the largest outbreak of severe weather so far this year," with the greatest risk for strong to intense tornadoes and hail larger than 2 inches in diameter stretching across Missouri, Illinois, Indiana, and Texas. Meteorologists are urging people in the target area to be prepared, identify safe shelter locations, and have multiple ways to receive weather warnings.
