LA CROSSE, Wis. – Drivers across western Wisconsin face dangerous visibility this morning as dense fog grips I-90 and surrounding highways. The National Weather Service warns that fog may reduce visibility to just a quarter mile or less until 9 a.m., creating hazardous travel conditions. Motorists are urged to slow down, use headlights, and leave extra distance on the road.
According to the National Weather Service in La Crosse, the Dense Fog Advisory includes portions of southeast Minnesota, northeast Iowa, and central to southwest Wisconsin. Cities like Black River Falls, Sparta, and Viroqua are waking up to near-zero visibility. By late morning, fog should lift, giving way to sunshine and warmer air.
Thursday afternoon will climb into the upper 70s under mostly sunny skies. Friday turns hotter, with highs near 82 degrees, before heat builds further into the weekend. Saturday and Sunday will push into the mid-80s, with a mix of sun and some clouds. A shift arrives Monday as scattered showers and thunderstorms return.
Travelers and outdoor planners should note the transition: calm, foggy mornings give way to hot afternoons, then a wetter start to next week. Stay alert for updated advisories, especially if thunderstorms strengthen Monday.
