Wisconsin starts the day locked in deep winter. Porch lights glow over frozen driveways, and the air bites hard with every breath.
Temperatures hover near 1 below zero early this morning in Green Bay. Northwest winds drive wind chills down to 15 below, with colder pockets nearing 20 to 25 below zero across north-central Wisconsin. Frostbite can develop quickly on exposed skin. Limit time outside and cover all skin.
Skies remain mostly clear to partly sunny through the day, but sunshine offers little relief. Highs struggle to reach 12 degrees. Winds stay light, yet the cold feels relentless. Pavement remains dry, though shaded areas stay slick from lingering ice. Drivers should watch ramps and bridges, especially along I-41.
Tonight turns sharply colder again. Temperatures dip to around zero, allowing refreeze on untreated surfaces. Flash freezing becomes a concern where daytime melting occurred. Walk carefully during evening errands.
Friday brings modest improvement. Mostly sunny skies help temperatures climb near 14 degrees. Conditions feel calmer, but it remains solidly wintry. Friday night lows fall back near 9 degrees, keeping cold stress elevated.
Saturday offers the best break. Sunshine pushes highs toward 22 degrees, though snowpack keeps mornings icy. Sunday stays mostly sunny with highs near 25 degrees. Attention then shifts to Sunday night, when a 50 percent chance of snow develops. While totals appear light, timing matters. Snow falling after dark could quickly freeze and create slick roads into Monday.
Meteorologists continue monitoring Arctic air locked over the Upper Midwest. With Lake Michigan nearby and cold ground in place, even minor snow can cause outsized impacts.
Dress in layers today. Keep emergency winter gear in vehicles. Check on vulnerable neighbors and pets.
