How many Halloweens has the Chicago area received snowfall?
— William J. Ooms Jr., Alsip
Halloween snow is extremely rare in Chicago, having occurred in only eight years since 1871, most recently in 1993. All of the occurrences were quite light, generally traces, a result of a chilly rain mixed with snow or just some passing flurries.
In 1994, Halloween brought just awful weather, with 2.26 inches of wind-driven rain soaking the city. Though it never snowed in Chicago, some western suburbs experienced a changeover to snow that coated grassy areas just before midnight.
Some readers have told us they remember trick-or-treating in snow in 1954, but that year Halloween fell on a Sunday and many areas delayed festivities until Nov. 1, when about an inch of snow fell.
