HOUGHTON – The winter storm that hit the Keweenaw on Monday was set to leave early Wednesday, but not before dumping more than a foot of snow across the region.
The storm began when a flow of moisture moved over a southerly frontal boundary into cooler air over the region, said National Weather Service meteorologist Don Rolfson. in Negaunee.
“We haven’t seen much this winter” he said. “That has led to this prolonged period of snow that we are seeing now.”
This morning there had been 10.5 inches of snow in Keweenaw County, according to the county highways commission. In general, most of the Copper Country had recorded between 4 and 8 inches as of Tuesday morning.
More heavy snowfall was on the way. A winter storm warning from the NWS issued late Tuesday morning predicted another 5 to 10 inches before the end of the warning at 7 a.m. Wednesday. The heaviest snow is expected to fall from Tuesday evening.
Gusts of up to 25 to 35 mph were expected on Tuesday evening. On the Keweenaw County shoreline, gusts could reach up to 40 mph, Rolfson said.
Blowing snow significantly reduced visibility, which affected nighttime travel, the NWS said. If people have to travel in such conditions, the NWS said, they should keep an extra flashlight, food and water in your vehicle for emergencies.
Being outside a vehicle couldn’t be better. With wind chills as low as 20 below zero, people can get frostbite on exposed skin in as little as 30 minutes, the NWS said.
We expected there to be a “decent clip” of snow overnight, Rolfson said, easing in the morning once drier air entered.
The storm won’t leave a tropical paradise in its wake. But aside from light lake effect snow, the weekend period should be calm.
“In general, it will be a quieter period,” Rolfson said.
Another blow of cold air over the weekend could cause a slight increase in lake-effect snowfall, but nothing comparable to the current storm, Rolfson said.
