Any evidence of the latter?
Let's see, June 2. Sort of a summer date, I suppose for most. And Fargo Forum is reporting:
It's June now, but residents in Minnesota's Northland area were waking up to sub-freezing temperatures.
A Duluth News Tribune report says the mercury dipped below 30 degrees in some areas Sunday morning.And so it goes. Even the Fargo Forum folks have noted it was June.
