Wisconsin greets the morning wrapped in a hard, unforgiving freeze. Streetlights glow over frosted rooftops, and the air burns with every breath near the Mississippi River.

Temperatures sit near 4 below zero early this morning in La Crosse. Calm winds help slightly, yet it still feels punishing outside. Exposed skin numbs quickly, and frostbite remains a concern during early commutes or school drop-offs.

Skies turn bright and sunny today, but the sunshine offers little warmth. Afternoon highs only reach around 12 degrees. Sidewalks and untreated roads stay icy, especially in shaded areas and along riverfront routes. Drivers should watch bridges and ramps where refreezing lingers.

Tonight stays cold but quieter. Temperatures dip near 4 below, allowing any daytime melt to refreeze fast. Flash freezing becomes a real issue after sunset. Walk carefully during evening errands.

Friday brings a modest improvement. Mostly sunny skies push highs near 13 degrees, though the cold remains sharp in the morning. Friday night lows hover near 1 below, keeping winter firmly in control.

Saturday looks calmer and brighter. Sunshine helps temperatures climb toward 20 degrees, offering the best outdoor window of the stretch. Still, snowpack keeps mornings slick and cold.

Attention turns to Sunday. Clouds increase by afternoon, and snow becomes likely later in the day, with chances near 60 percent. Accumulations appear light for now, but timing matters. Snow falling late Sunday could create slippery travel into early Monday.

Meteorologists continue tracking persistent Arctic air across the Upper Midwest. With frozen ground and cold nights, even light snow can quickly turn roads icy.

Limit outdoor exposure today. Dress in layers. Keep emergency winter gear nearby.
