Weather turns with cold snap

Graham Jaehnig/Daily Mining Gazette The Copper Country weather turned from mild to severe overnight on Tuesday, but a warmup is expected later in the week.

HOUGHTON — A stretch of mild weather in the western Upper Peninsula came to an abrupt end Tuesday night. Cold temperatures will return starting today, according to Matt Zika.

Zika, a meteorologist with the National Weather Service in Negaunee Township, said the cold is the result of air coming down from Canada.

“There’s a huge mass of low pressure over northern Ontario,” he said.

That low-pressure system brought in strong winds overnight from the west of up to 50 mph, Zika said. The cold air moving over Lake Superior also produced a few inches of lake-effect snow over much of the Keweenaw Peninsula on Wednesday and should continue Thursday, when things will calm down a bit.

“As we head into Thursday, the winds will diminish some,” he said. “The prospect of snow showers should diminish through the day into Friday.”

The high temperatures Wednesday and Thursday will be about 20 degrees, Zika said, but more extremely cold air will move into the area on Friday, with highs only in the teens and wind chills below 0 degrees.

There should be a warmup early next week, Zika said.

“By Tuesday, we should see temperatures around 30 into the lower 30s,” he said.

The normal high temperature for this time of year is about 40 degrees, Zika said.

Despite the cold, Zika said there are no large storms expected into next week.
