SIOUX FALLS, S.D. (AP) — A lingering snowstorm over the northern Plains is setting records.

The National Weather Service says 8.7 inches of snow fell in Sioux Falls Monday, breaking the city's record for the date of 7.6 inches in 1954.

Mitchell set a record with 7.2 inches, along with Sioux City, Iowa, with 6.6 inches.

Aberdeen didn't set a snow record, but the American News reports that conditions Monday afternoon were so poor that an incoming flight was unable to land and instead returned to Minneapolis.

Winter weather warnings and advisories remain in place for much of the Dakotas, with several more inches of snow expected by Tuesday evening. Several South Dakota schools announced late starts or canceled classes. Roads are reported in poor driving condition throughout much of the Dakotas.
