MINNEAPOLIS (WCCO) – An Arctic air mass is upon us, and according to WCCO meteorologist Lauren Casey, the cold will stick around for a while.

Temperatures have plummeted throughout the state, and winds are making matters worse – with speeds as fast as 61 miles per hour reported in Jordan. The winds will wane overnight, dropping to around 10-20 miles per hour.

Early Sunday morning, the temperature will dip down to -4 degrees. Factoring in wind chill, the late morning will feel like 10 below, with Grand Marais feeling like 40 below.

Potentially dangerous wind chills pick up for Sunday night into Monday for all metro counties. With the air feeling like 40-45 degrees below zero, frost bite is a real danger – sinking in after just 10 minutes of exposure. Keep your pets indoors as well during these brutally cold days and nights.

Monday will bring our first below-zero high in four years. Monday’s low is a harsh 14 below.

Expect winds to peter out by Tuesday, with the cold slightly retreating by next weekend.
