I spent far more time in the upper part of 'the Mitten' and Hemingway's stomping grounds of the U.P. of Mich. Even more in the Dakotas, than Minn./Wisc for length vs travel., but thought the woodlands more similar except colder; but I guess by winter temp reputation alone.
I always packed for extremes as rare as they are, they happen. Jacket and long johns, water, matches, heat pads, are in the truck year round anyhow.
U.P,; overnight, creek ice, heavy a.m. frost in every and any month is possible. Superior sends some cold wet crap down sometimes.
Mid-Mich, north of Saginaw to Mackinaw; does lowland July am frost on sleeping bags count? A few times, n.e. & n. w. Mich. both.
Off the Straights of Macknaw can be bitter out of the blue. s.W. to Cheboygan/Mullet Lake area treated me to crunchy hailish ice snows a couple of times.
Maybe 2 min long lake effect flurries around/over small water, no accumulation, gone in the sunlight if it lands on land.
June 3rd Detroit, 1990's. Nice early a.m. Started moving about 6o'clk. I wore shorts as it had been nice weather recently.
At 10:30a.m. it began snowing lightly and it lasted for about 40 min, no real accumulation except on cars that had run air conditioning vs heat that a.m..
I don't recall July-Aug snow in lower E. Michigan.
If you don't like Michigan weather
Wait an hour for the next front 😉
Ya know that white crap has followed me all the way to Florida once. I couldn't ditch it all week and Detroit was nicer the whole time. "The Feb. heat blast" two to 5 days each year it gets too nice to be "winter"... before it whomps you with a mystery finale 😒
