Like Illinois and Wisconsin. Recruit training in Illinois, but drinking age was still 18 in Kenosha and Milwaukee in 1982 and 1983, so I have a fondness in my heart. 82-83 was actually a fairly low snowfall year, but I do remember June and July temps in excess of 100ºF while Lake Michigan still felt like ice water. Gives me appreciation for the mid 80s water at Galveston. Upper 70s now, still comfortable, except beach season has obviously ended.

GFS output suggests surface temps near 40ºF, a tad warm for snow, but I think GFS has a feature that trends it towards climatology.
