Holiday vacations are coming to an abrupt end.
The snow has made Chicagoland roads more challenging for commuters.
Both O'Hare Airport and Midway Airport reported delays, and 235 flights out of O'Hare had been cancelled Sunday as of 8:30 p.m., according to the Chicago Department of Aviation.
Disruptions continued Monday, with more than 60 cancellations at O'Hare and about 235 delays.
Metra reported delays on many of its lines, including the Union Pacific Northwest, Milwaukee District, Burlington Northern Sante Fe, Rock island and Metra Electric.
Metra Spokeswoman Meg Reilly says the morning rush went “pretty well.” There were some mechanical problems that led to delays that were “more than likely weather-related.”
This evening, they will be amping up the snow plan which they started this weekend. That means additional staffing at outlying points and at key switching points, signal maintenance crews will now be working 24/7 until we get a break in temperatures and locomotives will be running overnight to stay warm.
Metra is also asking its customers to head to the agency's website, metrarail.com, and sign up for e-alerts to get the most current information about schedule changes and possible delays.
We are currently under a Wind Chill Advisory - and a Winter Weather Advisory begins this evening for several inches of snow.
The worst may be yet to come; with high winds and low temperatures, plows may have trouble keeping up with the snowfall.
Come Wednesday, we’ll be lucky to see temperatures climb above zero.
