After most of the Northland's first snow flurry of the season Thursday, the National Weather Service in Duluth is forecasting the season's first widespread accumulating snow event Saturday.
The weather service adjusted some its estimated snowfall totals in a Friday afternoon updated report and issued a winter weather advisory for much of Northeastern Minnesota. Southern St. Louis, Carlton and Aitkin counties were excluded from the advisory.
Between 2-6 inches of snow is possible across the Iron Range. Higher elevations along the North Shore could receive 4-6 inches. The weather service predicts less snowfall closer to the shore of Lake Superior. The shoreline and Twin Ports area is not forecast to receive more than two or three inches.
Up to 1 inch could fall in Northwestern Wisconsin and no more than 1 inch is expected to fall within 1 mile of Lake Superior's north and south shores.
The snow fall will begin early Saturday morning. The heaviest snow fall will occur late Saturday morning into early Saturday afternoon before turning into a mix of rain and snow showers later in the afternoon, according to the weather service.
Some roads will become slippery, especially in areas around the Iron Range and higher elevations of the North Shore where more snow is expected.
The weather service's confidence has "high confidence" that at least 1-3 inches will fall across the Iron Range and higher elevations of the North Shore and reported less confidence in the potential for the higher snowfall totals across a small area of higher terrain North Shore and northern Itasca County.
The weather service reported the Northland's first known snow flurry of the season north of Grand Marais on Oct. 1. The rest of the Northland's first dusting occurred Thursday night into early Friday morning, meteorologist Linda Engebretson said. Many Northlanders woke up Friday to a light dusting, but no real snow accumulation.
