I-70 through central Illinois – Travel conditions across central Illinois are expected to worsen this weekend as an arctic front brings dangerous cold followed by accumulating snow, particularly south of Interstate 70.
According to the National Weather Service in central Illinois, an arctic front is pushing through the region tonight, dropping wind chill values to between -5 and -30 degrees. The extreme cold is expected to persist through the weekend, increasing the risk of frostbite and creating hazardous conditions for anyone stranded on roadways.
A winter storm is forecast to impact the region Saturday into Sunday, with accumulating snow most likely south of I-70. Snow may fall heavily at times Saturday, before tapering on Sunday. Even lighter snowfall combined with bitter cold can quickly lead to snow- and ice-covered pavement, reduced visibility, and stalled traffic.
Major travel corridors including Interstate 70, Interstate 55, Interstate 57, and U.S. Route 51 are expected to see deteriorating conditions, especially Saturday night when snowfall chances peak and temperatures fall into the single digits. Wind chills near or below zero will make road treatment and recovery slower.
The Weather Service warns that travel impacts could extend into Sunday night, as cold temperatures will limit melting and allow slick conditions to persist. Motorists experiencing vehicle trouble could face life-threatening cold exposure in a short period of time.
Drivers are urged to avoid unnecessary travel, carry winter survival supplies, keep fuel tanks full, and check road conditions before heading out.
Commuters, students, and weekend travelers across central Illinois should prepare for dangerous winter driving conditions and prolonged cold exposure risks.
