With more than 1200 flights canceled at O'Hare and Midway on Sunday, the snowstorm made getting in and out of Chicago difficult, to say the least.
Among the frustrated travelers? The members of pop rock band OneRepublic.
The group was forced to cancel their concert scheduled for Sunday evening in Las Vegas, Nevada, delivering the bad news via Twitter around 1:45 p.m.
"To all our fans in Vegas- we are stuck in Chicago from the snow storm, we are so so sorry," the band tweeted. "Winter weather is wrecked our plans. This sucks."
They followed that post with another about an hour later, letting fans know that the opening acts for the "Not So Silent Night" concert would continue to perform as scheduled.
"But for the listeners, the fans and partners, the show will go on. The Fray, Lindsey Stirling and We The Kinds will still perform and the concert will now be free, and open to all who would like to come out for a great night of music," the band tweeted, adding that refunds would be issued to all who bought tickets.
OneRepublic was in Chicago to perform at Saturday night's "B96 Pepsi Jingle Bash" at the Allstate Arena in Rosemont, alongside Britney Spears, Shawn Mendes, Fifth Harmony and more.
Several inches of snow fell across the Chicago area beginning Saturday evening, as most counties remained under a Winter Storm Warning through late Sunday night.
