Michigan Braces for Arctic Cold and Lake-Effect Snow Through Weekend

Michigan is preparing for a significant drop in temperatures as an Arctic air mass moves into the region starting Thursday night. The National Weather Service forecasts that temperatures will fall well below zero across most of the Upper Peninsula and northern Lower Michigan by Friday morning, with some areas reaching minus 15 degrees or colder. Wind chills are expected to plummet to minus 35 degrees or lower, posing a risk of frostbite and hypothermia within minutes.

In addition to the extreme cold, lake-effect snow is anticipated to impact areas along Lake Superior, particularly the Keweenaw Peninsula and higher terrain, with accumulations of three to six inches. Winter Weather Advisories are in effect for northern Houghton and Keweenaw counties, where blowing snow and reduced visibility will create hazardous travel conditions, especially from Thursday night through Friday afternoon when winds of 20 mph combine with fine, powdery snow.

The Michigan State Police Emergency Management and Homeland Security Division urges residents to take precautions during this period of extreme cold. "With temperatures dropping below zero and dangerously cold wind chills on the way, it’s important to take extra steps to keep yourself and your loved ones safe," said Capt. Kevin Sweeney, deputy state director of Emergency Management and commander of MSP/EMHSD. "Dress in layers, limit time outdoors, and check on your neighbors who might need extra help. Staying informed and prepared can make all the difference during extreme weather like this."

Residents are advised to limit time outdoors, dress in layers, and check on vulnerable individuals. The bitter cold is expected to persist through at least Sunday morning, with single-digit highs and overnight lows dropping below zero in many interior locations of southern Lower Michigan. Lake-effect snow will continue intermittently through the weekend, though accumulations will be limited by the extremely cold air, which produces very fine snowflakes.
