Does Chicago get snow in May?

Dear Tom,
Chicago gets snow in April, but what about May?

Paul Witterberg,
Chicago

Dear Paul,
Snowfall in May is not that unusual in Chicago, having occurred in nearly 23 percent (30 out of 133) of the Mays here since 1885. In most instances the snow has not been measurable, falling either as flurries or as rain mixed with snow. Only eight Mays have produced measurable snow, most recently 0.5 inch May 6, 1989. May’s greatest snowfall was 2.2 inches on May 1-2, 1940; the city’s latest measurable snow was 0.2 inches on May 11, 1966. The last time it snowed here in May was a trace on May 2, 2005. Snowfall beyond May has only happened once in Chicago: In 1910 when a trace was observed on June 2. Autumn’s earliest snowflakes have been logged twice, traces on Sept. 25, in 1928 and again in 1942.
