Dear Tom,
I remember a June 11 back in the late 60s or early 70s with a killing frost that wiped out most of my garden. Details?

Dear Jim,
The very cold morning in the Chicago area that you remember was on June 11, 1972. In the city, the then official Midway Airport site logged a record low of 41 degrees (since tied in 1980), but the real chill was out in the suburbs where readings dropped into the lower and middle 30s. The morning's coldest temperature was logged in northwest suburban Marengo, a frosty 29 degrees. Other suburban lows that morning included Antioch, 33; Aurora 35; Barrington 30; Waukegan 34; Joliet 35; and Park Forest. 36.
The warming effect of the city's heat island and Lake Michigan was evident from the 46 degrees registered at the site in Grant Park near Buckingham Fountain.
