Duluth starts Monday under a relatively calm pattern, but forecasters are closely watching another clipper system set to move across the Northland late Wednesday into Thursday, bringing a complicated mix of precipitation before colder air fully takes control.
According to the National Weather Service, warmer air in place Wednesday will initially support rain or a rain/snow mix, especially during the afternoon and evening. As the system strengthens and colder air sweeps south overnight, precipitation is expected to transition to snow by early Thursday morning. This type of setup raises concerns for slippery roads, changing travel conditions, and reduced visibility, particularly during the overnight and morning commute.
Forecast guidance shows several phases to the system. Wednesday afternoon may feature mainly rain or a rain/snow mix in and around Duluth, while areas farther north could see more snow. By midnight, colder air begins to push in, increasing the likelihood of snow mixing in across the region. By Thursday morning, temperatures should be cold enough for all snow, with the potential for accumulating snowfall.
While exact snowfall totals remain uncertain, the transition period is often the most hazardous, as rain falling on colder surfaces or rapidly changing precipitation types can lead to icy patches. Gusty winds may also contribute to reduced visibility at times once snow becomes more widespread.
Residents are encouraged to use Monday and Tuesday to prepare, especially if travel is planned late Wednesday night or Thursday morning. Keep vehicles winter-ready, allow extra travel time, and stay updated on forecast changes, as even small temperature shifts can significantly impact precipitation type.
This system may not be a classic heavy snowstorm, but its messy nature makes it impactful. Duluth residents should be ready for rapidly changing conditions as winter reminds the Northland it still has plenty to offer this season.
