Butte and Anaconda set new records for low temperatures over the weekend, and weather this week will be “like a roller coaster,” according to the National Weather Service.
The mercury in Butte dropped to 1 degree Fahrenheit Sunday, beating a 1927 record of 10 degrees. The high of 19 degrees was also the coldest high temperature ever recorded for the day, breaking the record of 26 degrees in 1951.
“(The cold weather) doesn’t look like it will go away anytime soon,” said Gene Petrescu, a meteorologist with the NWS in Missoula.
In Anaconda, a low of 5 degrees Sunday broke a previous record of 11 degrees in 1927. The high that day, 18 degrees, also broke the mark for lowest high temperature for the day, which was 20 degrees in 1951.
“Anaconda probably also broke records (Monday) morning,” Petrescu said. “We haven’t gotten official numbers yet.” The cool weather, blowing down from Canada will stick around until the weekend.
“We will have periods of cooler shots coming down from Canada from time to time,” Petrescu said. “But it will warm up, and be warmer (Tuesday).” There may be some more cold air arriving in Butte Wednesday, but it won’t be as cold as last weekend, he said.
Sunday also broke the record for coldest temperature recorded so late in the season, but only held that title until Monday’s low of 2 degrees broke the record again.
Monday’s low also broke the cold temperature record for the day, which was 7 degrees in 1951.
