Marquette, MI — Another round of accumulating snow is on the way for Michigan’s Upper Peninsula as a developing system spreads widespread snowfall across the region today and into Sunday. The National Weather Service in Marquette reports that isolated morning snow showers will quickly transition to steadier snowfall by this afternoon, impacting nearly the entire U.P.
Snowfall totals of 3 to 6 inches are expected for most communities, with pockets of higher amounts possible—particularly in areas favored by lake effect snow off Lake Superior. Forecasters say northwest wind snowbelts will see lingering lake effect snow well into Sunday, creating locally heavier, more persistent bands.
A Winter Weather Advisory is in effect through Sunday for all of the Upper Peninsula.
Temperatures will remain cold with highs today in the mid-20s to lower 30s. Tonight, readings drop into the teens as snowfall continues, with wind chills dipping even lower. On Sunday, lake effect snow showers will continue, especially along the northwest shoreline, though coverage will gradually decrease late in the day.
Roads are expected to become snow-covered and slick as the steadier snowfall develops this afternoon. Visibility may deteriorate quickly under heavier bursts, especially in lake effect zones. Travelers should be prepared for slow travel, quickly changing conditions, and reduced visibility through Sunday.
The heaviest snowfall is expected between 1 p.m. Saturday and 1 p.m. Sunday, with plowable amounts likely for nearly the entire U.P.
Forecasters advise residents to monitor updates, as localized lake effect bands could push totals higher in favored zones. Cold temperatures will ensure snow remains powdery and easily blown around by gusty winds.
More weather updates are expected as forecasters track lingering snow showers and early-week conditions.
