SIOUX FALLS, S.D. (AP) — Record-setting cold weather continues to blanket South Dakota as the new year begins.

The National Weather Service says Aberdeen, Mobridge and Pierre set or tied record-cold temperatures for the date on Monday. The mercury plunged to minus 21 in Pierre, minus 30 at Mobridge and minus 32 in Aberdeen.

Aberdeen's previous record-low temperature for New Year's Day had stood for 99 years.

Several South Dakota cities also set cold-weather records over the weekend. Wind chill reports around the state early Monday were in the minus 30s, minus 40s and even minus 50s.

Nearly 1,000 people in Mitchell were without power for a couple of hours Monday morning before Northwestern Energy fixed the problem. The local fairgrounds and the Corn Palace were opened as emergency shelters but it wasn't clear if anyone used them.
