It may seem cold this morning but conditions will worsen with the passage of another cold front today. This will drop overnight lows from the single digits above and below zero south to -5 to -12 north. Winds will not be too strong but sufficient to produce widespread wind chills of 10 to 20 below and even 20 to 25 below zero north. This cold spell will be prolonged with similar conditions into Wednesday morning and then again over the weekend. In western Iowa, expect overnight lows ranging from -14 to -20.

With temperatures that cold, frostbite and hypothermia can occur if you are exposed to the elements if precautions are not taken. Wear multiple layers of loose-fitting clothing to stay warm.

Snow is also likely across northern Iowa Wednesday Night into early Thursday with accumulations of 1 to 3 inches possible.
