St. Louis, Missouri – Severe storms are expected to intensify rapidly Monday afternoon, threatening major travel corridors across the mid-Mississippi Valley with damaging winds, large hail, and possible tornadoes that could disrupt traffic on I-70, I-55, and I-44 within hours.
According to the National Weather Service Storm Prediction Center, storms will develop across Missouri, Iowa, and Illinois during the morning, then strengthen into organized supercells by mid to late afternoon. The highest risk zone stretches from Kansas City through St. Louis into central Illinois, with tornado potential increasing after 3 p.m. and continuing into the evening.
Cities including St. Louis, Springfield, Quincy, and Peoria sit in an enhanced risk area where wind gusts may exceed 75 mph and hail could reach 2 inches in diameter. Farther south, Memphis and Little Rock face storms by late afternoon, while Chicago and Indianapolis could see impacts between 6 p.m. and 10 p.m. as the system pushes east into the lower Ohio Valley. Downed trees and power lines may lead to scattered outages affecting thousands of customers.
Drivers should avoid unnecessary travel during peak storm hours and monitor conditions along I-55, I-64, and I-65. Charge devices and secure outdoor items ahead of the storms.
The severe threat will continue into late Monday night as storms shift east. Additional
