Temps dip to as low as 30 degrees in northern Minnesota Thursday

July 8, 2021 morning low temperatures  (NWS Duluth / FOX 9)

Thursday got off to a chilly start with many areas of northern Minnesota and northwestern Wisconsin seeing early morning temperatures in the 30s and lower 40s. 

Hibbing set a new record low of 34 degrees for July 8. Ashland, Wisconsin tied their record with a low of 36 degrees. 

The coldest spot was Brimson, a township in St. Louis County, which recorded an early morning temperature of 30 degrees. 

The chilly start Thursday morning was caused by a clear sky and very dry air brought on by a Canadian high pressure system moving over Lake Superior. The good "summer" news is that although dry air leads to cooler morning low temperatures, it also allows for rapid warm-ups. So the cool morning quickly leads to a mild and pleasant afternoon in the sunny 60s and 70s statewide.
