Do the suburbs get more snow than the city of Chicago?
Why do Chicago’s suburbs get more snow in the winter than Chicago itself?
— Matt, Palatine
I do not believe that to be the case. For example, the annual snowfall at Midway Airport is 39.3 inches (Midway being closer to the lake than O’Hare); at O’Hare International Airport, it’s 37.6 inches; at Rockford, 38.3 inches. The differences aren’t large, but they are significant nonetheless. Lake Michigan enhancement of snowfall totals and the occurrence of lake-effect snows in locations closer to the lake all argue that more snow will fall with some regularity at lakeside locations.
Please note that these are generalized statements. Individual snow events will not necessarily conform to the “more snow near the lake” phenomenon. However, averaged over a period of many years, lakeside locations receive more snow than inland locations.
