Dear Tom,
How often has it been 90 degrees or higher on Memorial Day? Has the temperature ever failed to reach 70 degrees?

Dear Nick,
Memorial Day, originally known as Decoration Day, is a national day of remembrance of U.S. men and women who died while in military service. Until 1970, Memorial Day was always observed on May 30, but since 1971 it has been observed on the last Monday of May (and the date varies from May 25 through May 31).
On average, the Memorial Day temperature climbs to 90 degrees or higher on one day out of eight. However, Lake Michigan, whose water temperature off Chicago is often in the 40s in late May, greatly reduces the occurrence of 90-degree days to about one in 70 at the lakeshore. High temperatures fail to reach 70 degrees quite often: one day in three inland, and one day in two at the lakeshore.
