by Duluth, Minnesota — Duluth residents are waking up to clear skies and sharply cold air rolling off Lake Superior, a calm start that belies an approaching weather system set to complicate early Thanksgiving travel.
With the holiday rush beginning midweek, forecasters say conditions are expected to shift quickly, bringing rain, gusty winds, and a slight chance of a rain-snow mix Wednesday night. For travelers planning to hit the highways or the airport, timing will matter.
Cold but Quiet Conditions Hold Through Today
A high-pressure pattern continues to dominate the early week, keeping skies mostly sunny and temperatures steady in the upper 30s Tuesday. The east wind adds a crisp bite, but roadways across Duluth and surrounding communities are dry and clear, supporting trouble-free visibility from the Blatnik Bridge to the shorefront.
Overnight, clouds begin sliding into the region, and temperatures dip into the mid-20s, keeping frost concerns in play. The chilly overnight setup is part of the broader shift forecasters have been tracking for the next 48 hours.
“Conditions remain stable through Tuesday, but changes arrive fast once southwest flow pulls in deeper moisture,” local meteorologists noted in the National Weather Service Duluth update.
Moisture Increases Wednesday as Clouds Take Over
Wednesday brings a noticeable shift as skies turn mostly cloudy and temperatures hover near 40 degrees. Winds strengthen out of the southwest, carrying moisture into the region. While the day’s travel window remains manageable, the atmosphere becomes primed for deterioration after sunset.
By late Wednesday night, rain becomes likely, particularly after midnight. Temperatures stay just warm enough to keep most precipitation liquid, forecasters say. Still, Duluth’s lake-cooled microclimate introduces a small but real possibility of wet snow mixing in on higher terrain along the hill.
“Any rain-snow mix would be brief, localized, and unlikely to accumulate, but travelers should remain alert to sudden changes,” meteorologists cautioned.
Thanksgiving Morning Could See Lingering Showers
The incoming system is poised to impact early Thanksgiving plans. Rain remains possible Thursday morning, especially before noon, although widespread cold-weather hazards are not expected.
Visibility may reduce temporarily along I-35, the North Shore, and bluff-top neighborhoods as light rain and gusty winds sweep through. Drivers heading to early gatherings should allow extra travel time and prepare for wet road spray.
By midday, conditions begin to improve, with clouds breaking into a partly sunny sky. However, stiff west winds up to 20 mph, with higher gusts at exposed elevations, could still challenge high-profile vehicles.
Travel Impacts for the Holiday Week
Wednesday afternoon through Thursday morning represents the highest-impact window for travel in and around Duluth. Air travelers may see minor delays due to the moisture-rich pattern, although major disruptions are not anticipated.
Road commuters should monitor Minnesota 511, which provides real-time mapping tools, reports, and advisories for interstate and regional travel. The combination of wet pavement, reduced visibility, and lake-driven winds could present brief but meaningful hazards.
Meanwhile, those traveling later in the weekend will encounter calmer conditions.
Quieter Weather Returns Friday Through Sunday
By Friday, high pressure builds back over the region, restoring stable skies and temperatures near 39 degrees. This will likely be the smoothest travel day of the extended holiday weekend.
Saturday stays partly sunny and seasonably cool with a high near 41, offering another solid window for shoppers, return travelers, and anyone tackling pre-winter tasks like yard cleanup or holiday decorating.

Sunday slips slightly warmer into the low 40s, with mostly sunny skies returning. This final stretch before December provides a welcome break after the midweek system, with weather broadly favorable across the Arrowhead.
