Springfield, Illinois – Evening travel and outdoor plans across central Illinois and into western Indiana could quickly turn dangerous Thursday as severe storms ramp up with increasing tornado potential and damaging winds after 5 p.m.
According to the National Weather Service in Lincoln, most of central and southeast Illinois is under a Level 2 severe storm risk, with the most intense activity expected late afternoon through the evening. Storms may initially form as isolated cells near and north of I-74 before organizing into a line pushing east at 45 to 50 mph.
Communities including Springfield, Champaign, Decatur, Bloomington, and Terre Haute face the greatest threat window, where wind gusts could reach 60 to 70 mph and hail may exceed golf ball size. Forecasters warn that any discrete storms ahead of the main line could produce brief tornadoes, especially in east central Illinois.
As storms consolidate into a line, the primary hazard will shift toward widespread wind damage capable of downing trees and power lines, with scattered outages possible. Heavy rain may also trigger localized flooding on secondary roads and low-lying areas.
Drivers along I-55, I-57, I-72, and I-74 should be prepared for sudden visibility drops and strong crosswinds during the evening commute.
Residents are urged to review severe weather plans, enable alerts, and be ready to move indoors quickly if warnings are issued.
Storms are expected to push into Indiana later Thursday night, with additional watches or warnings possible as conditions evolve.
