Rare July frost: Record cold this morning up north

We’re used to seeing chilly temperatures up north even on the fringes of summer. But frost in July is actually pretty rare in northern Minnesota.

A cold and very dry air mass this morning produced low temperatures in the 30s across much of northeast Minnesota away from the protective warmth of Lake Superior’s waters. Temperatures plunged to 34 at Hibbing, a record low. It got as cold as 30 degrees at Brimson this morning.

Here’s a list of low temperatures around northeast Minnesota and northwest Wisconsin from this morning.

Friday brings another cool morning, but temperatures should be about 10 degrees milder with lows mostly in the 40s to lower 50s.

I hope campers brought the down sleeping bags up north this week.
