Thermometer showing temperature in Des Moines. Iowans are waking up to more bitter cold weather, with some of the coldest temperatures in years. A Wind Chill Warning blankets a dozen states, from the Dakotas to New York — and 79 of Iowa’s 99 counties.

National Weather Service meteorologist Craig Cogil says the warning’s in effect at least until noon, as wind chill levels may reach as low as 50-degrees below zero. Cogil says the regular air temperatures, without the wind chill factor, are extreme as well. Air temps are 10-below in southern Iowa and 25-below in the north.

Cogil says it’s still too early to say anything about record lows in the state, but he says there is some good news in the forecast.

A warm-up into the 30s is expected for the weekend.
