Arctic high pressure will build into the northern plains Saturday night into Sunday morning, with the coldest air of the season flooding into the state.Wind speeds of 10 to 20-mph will combine with low temperatures from zero to almost 12 below to produce dangerously cold wind chills overnight.

Dangerous wind chill temperatures are expected tonight through Sunday morning, and likely again Sunday night into Monday morning. Wind chill temperatures tonight will fall through the evening hitting warning criteria between 9pm and midnight and remaining in warning criteria through Sunday morning.

Air temperatures will fall into the teens below zero, with wind chills of 30 to 40 below, with only slight moderation on Sunday.  Frostbite can occur to exposed skin within 15 minutes or less.

A wind chill warning means the combination of very cold air and strong winds will create dangerously low wind chill values. This will result in frost bite and lead to hypothermia or death if precautions are not taken.
