The arrival of March brings a weird milestone to Chicago this year: The city recorded no snow on the ground in January and February for the first time in at least 146 years, reports the Weather Channel. In fact, the last snowfall of more than an inch occurred on Dec. 17, days ahead of the official start of winter, which means the city has been virtually snow-free all season. The Chicago Tribune notes that flurries were seen on a few days, but not enough to register when the official morning tally was taken at O'Hare International Airport. It's possible the streak goes back longer, but the 146-year mark reflects the start of National Weather Service data. Forecasts called for possible snow this week. Winter wraps up on March 20.
