Green Bay, Wis. – A bitter, hazy glow hovers over the Fox River this Saturday morning as dense freezing fog settles across Brown County, coating parked cars and neighborhood mailboxes in a thin silver crust. The cold air bites at exposed skin, and visibility shrinks to a few hundred feet at times, creating slowdowns on I-43, Highway 41, and local bridges. Travelers beginning early Thanksgiving trips should drive with low beams, widen following distance, and expect shifting pockets of near-zero visibility.
According to the National Weather Service Green Bay office, the Dense Fog Advisory lasts through 9 a.m., with the lowest visibility where recent snow lies. Once the fog lifts, mostly cloudy skies hold temperatures near the lower 40s. According to WisDOT, slippery ramps and frost-prone bridges could complicate travel through midmorning. Residents should clear windshields thoroughly, charge phones, and prepare for minor delays as traffic gradually increases heading into the holiday week.
A calmer pattern emerges Thursday with highs near the upper 40s, though clouds linger. Models hint at a small “Winter Tease” early Friday if colder air briefly dips south, but the day trends sunnier with improving travel conditions across northeast Wisconsin. To be fair, any flurry risk stays minimal, yet the sharp morning chill still warrants layers for shoppers and early travelers.
Saturday and Sunday appear brighter and quieter, offering comfortable time for yard cleanup or outdoor decorating before Thanksgiving’s final rush. After all, November weather often flips quickly, and residents should monitor any late-week adjustments as regional patterns shift.
