MINNEAPOLIS (AP) - Minnesota just can't seem to shake off the polar plunge.

The National Weather Service says International Falls reports a low of 26 below zero. Grand Marais dropped to 20 below, Hibbing dipped to 19 below and Alexandria bottomed out at 18 below.

By late Sunday morning, temperatures ranged from the mid-teens below zero in northern Minnesota to near zero in the far southwest and far southeast. Some wind chills readings were as low as 40 below in northern and western Minnesota.

Winds will increase across Minnesota on Monday. Temperatures will remain below normal but will be warmer than Sunday, with highs in the low teens in the northeast and southeast and upper 20s west.

A wind chill warning is out through Monday morning except for northwest and southwest Minnesota.
