Lake Michigan Ice Mounds by Mark Swanson

The Lansing State Journal reports the National Weather Service says that a triple threat of subzero temperatures, high winds and ice-free Great Lakes really piled up the lake effect snow last week:

“This snowy week is nearly at an end, including a visit from real Arctic air, and many towns near Lake Michigan and Lake Superior got a foot or two of fresh snow as a result,” the NWS said. “Clearly, the vast majority of snow was a result of lake effect, as plenty of other parts of Michigan only saw an inch or two at best.”

Air temperatures in Michigan fell below zero Jan. 18-22. In some cases, the thermometer didn’t read above zero for two days. The coldest reading in the state came Monday night when Stambaugh, in the western UP, registered minus 30 — before wind chill. The town also saw minus 28 on Tuesday night while Ironwood’s NWS observer recorded minus 27.

You can see that the conditions have also piled up shoreline ice in these pictures that Mark took over the weekend at Lincoln Township Beach just north of Grand Mere State Park. Here are some more recent ones and a shot from summer of 2016 below. More in Mark’s 2025 gallery on Flickr!
