Does the fact we’re way above average for rain fall this summer mean we are likely to have more than normal snow fall this winter?
It certainly has been wet in the Chicago area in recent months. We had Chicago climatologist Frank Wachowski check the records and he found that this year’s May 1- mid October period has logged more than 31 inches of rain, the city’s third largest precipitation total dating back to 1871. Wachowski highlighted the 10 wettest similar periods and checked the snowfall totals for the winter that followed. Based on the city’s current average snowfall of 36.3 inches, the 10 winters averaged about 42 inches of snow. Three winters were below normal, one about normal and six above normal . The extremes ranged from 82.3 inches in the winter of 1977-78 to 19.8 inches in the winter of 2011-12.
