Correction

I just checked. This is from the Minnesota Climatological Working Group:

As it stands right now the latest recorded measurable snow in Minnesota remains at 1.5 inches at Mizpah in Koochiching County on June 4, 1935 and the earliest documented snow in Minnesota is a trace that fell at the Duluth Airport on August 31, 1949.

Assuming this is correct, I probably have not seen snow in June; and it has never snowed in July.
