Green Bay, Wisconsin – Drivers across northeast Wisconsin have a narrow window to prepare before a Thursday morning rain-snow mix creates slick stretches on major routes like I-41 and Highway 29, with temperatures falling sharply by early Friday.
According to the National Weather Service in Green Bay, the only precipitation chance arrives Thursday morning, with light rain possibly mixing with snow in northern areas between 6 a.m. and noon. While accumulation remains limited, surface temperatures near freezing in outlying counties could lead to patchy slick spots, especially on bridges and untreated roads.
By Thursday afternoon, colder air begins pushing in, dropping highs into the upper 30s to near 60 before plunging overnight. Friday brings a noticeable shift, with highs only reaching the low to mid-40s, marking a 10 to 20 degree drop statewide. Brown, Outagamie, and Oconto counties will feel the sharpest change during the morning commute.
Drivers should allow extra travel time Thursday morning, watch for reduced traction on elevated roadways, and keep devices charged in case of minor delays. No widespread power issues are expected, but gusty conditions could develop behind the front.
A rebound begins Saturday, with temperatures climbing back into the 50s and reaching the low 60s by Sunday. Additional updates may be issued if Thursday’s mix trends colder.
