DAVENPORT, Iowa (AP) — Several schools, businesses and agencies are remaining closed as Iowa’s record-breaking and dangerous deep freeze continues. The National Weather Service has posted wind chill advisories or warnings for Iowa, but they’re expected to expire later this (Thursday) morning. The bitter cold that beset the nation’s midsection broke records in several Iowa cities Wednesday, including Des Moines. The minus 20 handily broke the 1965 low of minus 17. The Wednesday wind child hit minus 40.

The minus 25 degrees in Waterloo broke the Jan. 30 record of minus 24 set in 1951. Estherville, Lamoni, Mason City and Ottumwa also had record low temperatures. Here in southwest Iowa, many schools are running two-hours late this morning, due to the chilly weather.
