Duluth, MN (KDAL) - The coldest temperatures of the year are here for the start of February.  Double digit cold has invaded the Northland, dropping down from Canada.  That means some school closings and delays.

Running two hours late today are the Northwood's school district in Minong and classes in Blackduck.  Closed because of the cold are the Hurley School District and Chief Bug-O-nay-ge-shig near Walker in Northern Minnesota.

Please take it easy in the outdoors and bundle up.
