The National Weather Service is warning of life-threatening cold weather in Iowa over the next few days.
Temperatures could plunge to minus 30 and wind chills could reach 60 below. Forecasters warn it will be the coldest air mass across the Midwest in nearly 20 years.
Illinois Governor Pat Quinn says more than 100 warming centers will be available for
people who need shelter. Some cities
will use libraries, community centers and park district buildings.
