Parts of northern Minnesota dropped into the 30s and 40s below zero early Saturday.
The National Weather Service relayed a report of 42 degrees below zero at Kabetogama in northern St. Louis County. A weather station in Togo reported a low of 40 below.
Other low temperature reports included:
Bemidji — which is hosting outdoor hockey games on Saturday as part of the annual Hockey Day Minnesota celebration — dropped to 31 below zero to start the day.
To the south, the Minneapolis-St. Paul International Airport reported a low of 1 below zero on Saturday morning — the first time the airport has recorded a subzero temperature this winter. That sets a record for the latest first subzero reading in a winter — beating the previous record of Jan. 18, set in the winters of 1888-89, 2001-02 and 2011-12.
A wind chill advisory is in effect through midday Saturday for northern and far western Minnesota.
