NEGAUNEE - It's a bit nippy out there, but temperatures should warm up to a relatively balmy 22 degrees by Saturday, according to the National Weather Service.
Kevin Crupi, meteorologist with the NWS Negaunee Township office, said a trough system is allowing cold air from Canada to drop down to the south.
"That northeast flow is funneling a lot of cold air into the United States," he said. "The whole northeast United States is turning cold."
Cold weather forced the closures of all Copper Country K-12 schools today.
Crupi said the cold is even reaching into the Deep South, where temperatures are in the teens and 20s in Arkansas and Alabama.
The trough allowing the cold air to drop down from Canada is stationary, Crupi said, and isn't expected to move for a while.
"We're going to see cold the next several days," he said.
Today, Crupi said temperatures at 8 a.m. were: minus 8 at the Houghton County Memorial Airport with a wind chill of minus 28, minus 4 at Copper Harbor with a wind chill of minus 27, minus 8 for Baraga and minus 8 for Pelkie.
There will be a warming trend toward the end of the week, Crupi said, with temperatures above normal, which for this time of year is highs of 22 degrees and lows of 5 degrees.
Crupi said until 7 a.m. Wednesday there will also be a moderate lake effect snowfall with up to 6 inches in some areas south of Houghton and into Ontonagon. There will be wind chills ranging from minus 20 to minus 35, so being properly covered outside is important.
"Dress in layers and cover any exposed skin," he said.
Throughout the state, at least 30 school districts have canceled classes as sub-zero temperatures continue gripping parts of Michigan.
Downstate utility DTE Energy said most power outages caused by high winds over the weekend have been restored. The utility said about 3,000 customers in southeast Michigan remained without power at 9 p.m. Monday, down from a peak of more than 120,000.
DTE said crews were working 16-hour shifts.
