Springfield, Illinois – Drivers across Illinois should brace for a rough overnight as strong thunderstorms roll in after midnight, bringing 60 mph wind gusts, quarter-sized hail, and a slight risk of tornadoes north and west of I-55.
According to the U.S. National Weather Service Central Illinois, storms are expected to develop late tonight as a cold front sweeps through the state. The severe threat will continue into Tuesday morning, gradually exiting the area by early Tuesday afternoon. Areas including Peoria, Bloomington, Springfield, and Decatur are under a Level 1 to Level 2 severe risk, with isolated flash flooding also possible during heavier downpours.
Cities like Lincoln, Jacksonville, and Pontiac could see brief but intense bursts of damaging winds and hail early Tuesday, particularly during the morning commute.

Residents are urged to secure loose outdoor items, charge mobile devices overnight, and avoid flooded roads during morning travel.
The severe weather window is expected to close by early afternoon Tuesday, but officials warn that additional advisories could be issued if the storm system lingers longer than expected. Stay tuned to local alerts for updates through Tuesday morning.
