Late May 1947 Snowstorm

Dear Tom,
In late May 1947, Wisconsin was hit by a snowstorm. What was the weather
like in Chicago?

Dear Bruce,
It seems incredible, but an unprecedented late-spring snowstorm did strike
portions of the Midwest from northern Iowa to eastern Upper Michigan with as
much as 10 inches of snow on May 28-29, 1947. Hardest-hit Wisconsin areas
were in the southwest portion of the state where 10 inches of snow fell just
south of La Crosse. The weight of the heavy snow caused severe damage to
power and telephone lines and the already-leafed-out vegetation. The
responsible storm center passed south of Chicago, bringing the city a cold
rain and some thunderstorms, highs in the 50s and strong winds. The storm
produced high swells and high waves on Lake Michigan from Kenosha to
Milwaukee, damaging waterfront property. Chicago did set a record low of 38
degrees on May 29, 1947, but that was eclipsed by a 37 degree low in 1984.
