Frosty first day of school in Northland

Those warm summer days felt far, far away Tuesday morning as many Northland students headed back to school.

Low temperatures reported by the Weather Service and its spotters included 31 at Brimson, 32 at Togo, 33 at Embarrass and 34 at Hibbing and Crane Lake.

Ely, Moose Lake and Hayward each dropped to 36; Floodwood fell to 37, International Falls 38 and Cloquet 39. The Duluth airport reported a low of 46.

It’s all a sign of things to come, of course. The Weather Service reports Duluth’s average highs in September tumble from the low 70s at the start to the upper 50s by month’s end. Overnight lows drop from the low 50s to about 40. And, on average, Duluth sees a tenth of an inch of snow in September.
