Michigan’s Upper Peninsula is bracing for a powerful blast of winter, and conditions will deteriorate quickly after sunset. Snow bands are lining up west of Marquette, and gusty winds will soon whip that snow into whiteout bursts.
Temperatures sit near 19 degrees this morning at Sawyer International Airport. Patchy fog lingers early, but skies turn mostly sunny with highs near 35 degrees. That quiet stretch will not last long.
According to the National Weather Service in Marquette, a Winter Storm Warning takes effect at 7 p.m. and continues through 7 p.m. Wednesday for Marquette, Baraga, Keweenaw, and northern Houghton counties. Heavy mixed precipitation is expected, with total snow accumulations between 5 and 11 inches. Ice accumulations could reach one-tenth of an inch. Wind gusts may peak near 50 mph, especially over the Keweenaw Peninsula.
Snow develops this evening and intensifies late. By daybreak Wednesday, roads along US-41 and M-28 will likely be snow-covered and slick. Blowing snow will sharply reduce visibility. Travel could become very difficult during both the morning and evening commutes.
Winds stay brisk Wednesday with additional snow and highs near 31 degrees. Prepare for possible power outages where ice and wind combine.
Snow showers linger Wednesday night, then scattered snow continues Thursday with highs near 35. Another round of snow is possible Friday, reinforcing a cold, wintry pattern into the weekend. Highs hover in the upper 20s to near 30 Saturday.
Flash freezing is possible later this week as slush refreezes after sunset.
Looking ahead, the 6–10 day outlook hints at moderating temperatures by early next week. A gradual warming trend from Monday into late February may bring subtle spring warmth back to Upper Michigan. Are you ready for this round of winter vengeance?
