DULUTH — Parts of the Northland away from Lake Superior saw their first frost of the season and a few areas even saw a hard freeze Tuesday morning as temperatures fell into the upper 20s and lower 30s.

Cook appeared to be the coldest spot in Minnesota with a temperature of 28 degrees at 7:30 a.m., according to data from the National Weather Service in Duluth.

Other cold spots this morning included 29 in Bemidji, 30 degrees at Orr and Aitkin and 32 in Bigfork, Hibbing, Walker and also Grand Forks, North Dakota. International Falls saw a low of 36 degrees and Ely dropped to 34.

Duluth International Airport dropped as low as 34 degrees while it was a balmy 41 at Sky Harbor Airport on Park Point.

Siren appeared to be the cold spot in Northwestern Wisconsin with a low of 31 degrees with 36 degrees in Superior and 34 in Solon Springs.


Frost is possible again Wednesday morning before a gradual warmup later in the week, with highs in the 60s and lows in the 40s by Thursday and Friday.

Frost can occur even in the mid-30s depending on meteorological conditions and this year’s first of the season will be a little later than average for some areas of the Northland.

The National Weather Service in Duluth says the average first hard freeze, when temperatures dip to 32 degrees or colder, occurs Sept. 8 in Hibbing and Sept. 11 in International Falls, among the earliest in the state, with the average first freeze Sept. 14 in Mellen, Wisconsin, Sept. 21 in Brainerd and Sept. 30 at Duluth International Airport and Two Harbors.
