Marquette, Michigan – Rain showers and possible thunderstorms will move across Upper Michigan Friday before colder air brings snow early Saturday.
According to the National Weather Service in Marquette, morning fog and drizzle may develop Friday before showers increase during the afternoon as a storm system moves through the region.
A few rumbles of thunder are also possible later Friday, with additional showers continuing overnight across much of the Upper Peninsula.
Rainfall totals across parts of the region could reach around one-half inch, with some areas possibly seeing locally higher amounts.
Forecasters warn that rain combined with melting snowpack could lead to localized flooding on low-lying roads, especially in areas where drainage is poor.
Cities including Marquette, Houghton, Ironwood, Escanaba, and Sault Ste. Marie may see periods of steady rain through Friday evening.
Late Friday night into Saturday morning, colder air moving into the region may cause rain to change to snow, especially across the central and western Upper Peninsula.
Snowfall totals are expected to remain relatively light, with around 1 to 2 inches possible in parts of western Upper Michigan before precipitation tapers off Saturday.
Temperatures Friday will reach the low to mid-40s across much of the region, while overnight lows may drop into the upper 20s to near 30 degrees by Saturday morning.
Conditions are expected to improve later Saturday, followed by a gradual warming trend heading into Sunday.
By Sunday, highs across the Upper Peninsula could climb into the mid-40s to mid-50s, bringing milder conditions after the brief return to snow.
Drivers across Upper Michigan should remain alert for wet roads, reduced visibility in heavier showers, and potential slick spots early Saturday if snow develops.
