The National Weather Service Chicago has provided a wonderful recap that puts our recent Active Stretch of Winter Weather in Perspective, while at the same time forecasting more snow on Sunday.
First, the look ahead, then the recap of our three weeks of winter’s “greatest hits.”
Snow on Sunday
A period of accumulating wet snow is expected primarily Sunday (Feb. 21) afternoon and evening, with a window of higher snowfall rates late afternoon into the evening.
Snowfall amounts of 2 inches or more are possible, mainly north of I-80, with the potential for localized amounts up to 4 inches. The precipitation will diminish by around midnight for most of the area, but light snow may continue through the overnight hours.
Continue to monitor for forecast updates this weekend!
