Rare Late-Season Snowstorm Blankets Upper Midwest

Though it has been astronomical spring for over one month, winter still made its presence felt over much of the Upper Midwest last weekend. A rare, late-season snowstorm blanketed parts of Illinois, Wisconsin, and Michigan last Saturday, with the heaviest snowfall occurring in northern Illinois. St. Charles, IL measured 6.0 inches of snow by early Sunday morning for the highest snow total in the region. Officially at Rockford International Airport, 3.7 inches of snow fell, which is Rockford’s largest snowstorm this late in the season and its latest measurable snowfall since 1994.

Even Chicago couldn’t escape the spring snowfall, as O’Hare Airport officially recorded 2.5 inches of snow. This was O’Hare’s latest single-day snowfall of 2” or greater and its latest measurable snowfall since 1989.

No more snow is expected over northern Illinois. However, multiple rounds of rain are expected over the next week, which has the potential to lead to flooding across much of the region.
