Measured official snowfall from Jan 15 to Feb 15 on Chicago's northside (O'Hare Airport) was 38" in 30 days. On the city's southside (Midway Airport) it was 40" of snow during the same 30 day period. There is no "official" snowfall amount for rural Lake County, IN where I live but I have to suspect it is in the same range as those Chicago measurements. There were a few snowfalls where we got more than the city, a few when we got less than the city.Looks like you have more snow than us.
