Early frost hits parts of Minnesota

Temp in Tower dips to 25

From staff and wire reports

Frost in August? In Minnesota this summer, you better believe it.

Early morning temperatures Thursday were low enough for scattered light frost in parts of central and northeastern Minnesota, the National Weather Service said.

Tower in northeastern Minnesota had an overnight low of 25 degrees while Embarrass dipped to 27, the weather service said.


In southern Minnesota, the mercury fell to 40 degrees in Austin just before 6 a.m., within 2 degrees of tying a 37-year-old record. The low temperature Thursday in Rochester was 41 degrees.

Climatologist Greg Spoden said the low temperatures in Tower and Embarrass were daily records. In Tower, the old record was 27 degrees set in 1997, while the previous record in Embarrass was 29 degrees set in 2000.

The two northeastern Minnesota towns are in low valleys where cold air tends to pour in and settle, he said. They traditionally are two of the coldest places in Minnesota.

International Falls and Duluth reported record lows.

International Falls fell to 36 degrees, breaking the old record of 37 set in 2002, while Duluth bottomed out at 37, breaking that city's record low of 39 set in 1991.

In western Minnesota, Morris reported a record overnight low of 38, breaking the old record of 40 set in 1985. Hutchinson in central Minnesota tied the record low of 42 set in 1967.

Below normal low temperatures were reported again this morning. In Rochester, the temperature at 7 a.m. was 48.9 degrees at the airport. The normal low for today is 58 degrees. The record low, set in 1950, is 35 degrees.
