MARSHALL — The hot spell that arrived in Minnesota over the weekend set new temperature records in Marshall, National Weather Service data said.

On Sunday, Marshall broke records with a daytime high temperature of 93 degrees. At the same time, the low temperature for that date was also the warmest it had been in 70 years.

“The normal highs for this time of year are in the upper 60s,” said Samantha Trellinger, a meteorologist at the National Weather Service office in Sioux Falls.

Sunday’s high temperature of 93 degrees broke a previous record for Oct. 1, that was set in 1997. The previous record high was 92 degrees, Trellinger said. However, that wasn’t the only new record set for that date.

“We had a warm low,” she said. The low temperature on Sunday was 68 degrees. The next warmest low temperature for Oct. 1, at 65 degrees, was recorded in 1953, Trellinger said.

Data on Monday’s high and low temperatures wouldn’t be in until the following day, Trellinger said. However, weather forecasts Monday predicted another day where temperatures would get into the 90s.

Trellinger said a few different factors, including the dry weather the region has had this summer, and an upper ridge high pressure system, contributed to the unusual heat.

Temperatures in the 80s and 90s were reported all across Minnesota on Sunday. The National Weather Service reported a record-breaking high temperature of 92 degrees in the Twin Cities. According to the Minnesota State Climatology Office, it was the highest temperature ever recorded in the Twin Cities this late in the season. Due to heat risks on Sunday, organizers of the Twin Cities Marathon canceled the event.

The State Climatology Office said the highest temperatures recorded in Minnesota on Oct. 1 were 96 degrees at Theilman, and 95 degrees at Milan and Lamberton.

Trellinger said a cold front will move in this week, bringing along more seasonal temperatures in the 60s and 50s.

There will be a chance of rain today. “After (Monday), it should go back into fall-like conditions,” Trellinger said. “It should hopefully be a little more persistent,” she said.
