Marine Weather and Tide Forecast for Marinette, WI

DISCUSSION
Issued at 229 AM CST Fri Feb 6 2026

Snow will continue across the area this morning,. focused mainly along the leading edge of the cold air advection. Lift from the LFQ of an upper jet has helped make for some higher rates despite the fast movement of the snow showers, with visibility dropping to around a mile at times for much of the area. Would expect the overall accumulations to be between half an inch to an inch for most, with areas in east-central Wisconsin likely getting towards the higher end closer to an inch. This will likely make for some slick spots again for the morning commute, but the highest snowfall rates are expected to move off by the mid morning hours, which should help reduce the impacts. Still, some light flurries and snow will likely stick around behind the higher amounts, only ending as we get closer to noon. This later period will be one to watch as some light mixed precipitation could mix in at times as ice crystals aloft become scarce due to drier air pushing in.

Quiet conditions are then expected for the rest of the Friday into Saturday morning as colder air arrives. Expect low temperatures to drop below zero for portions of central and north-central Wisconsin while lingering only a few above in east-central, which will make for a cold start to the day on Saturday. High temperatures will be in the teens during the day. The cold will not be around for too long however as warm air advection returns to the region aloft during the afternoon and evening. Coupled with a shortwave aloft, would expect another round of light snow to move over the region late Saturday into Sunday, very similar to yesterday and this morning. Snow totals will again be on the lighter side, sitting around an inch or less for most (probabilistic guidance paints out 20-30% chance of exceeding an inch at any one location).

Warmer air then continues into next week, which will bring some above normal temperatures into the region. High temperatures will get into the 30s for most of the region and a few of the warmest spots may even get to around 40. Another shot for some light precipitation will be possible around the middle of next week but the details such as p-type remain uncertain at this time.
