La Crosse, WI – Drivers across La Crosse and western Wisconsin are urged to use caution Thursday as rapidly falling temperatures and snow showers could create dangerous flash-freeze conditions on roadways.
According to the National Weather Service in La Crosse, confidence is increasing that a flash freeze could develop Thursday afternoon and evening as temperatures tumble from the upper 30s into the teens behind a strong cold front. Even brief snow showers may quickly freeze on contact with wet pavement, leading to slick and icy roads with little warning.
Forecasters say snow showers combined with gusty winds could also produce localized snow squalls Thursday afternoon. While snowfall totals are expected to remain light, these fast-moving squalls can dramatically reduce visibility in a matter of minutes, creating sudden whiteout conditions for motorists.
The National Weather Service estimates a 30 to 50 percent chance of flash-freeze conditions developing Thursday afternoon, with a 30 to 40 percent chance of snow squall activity in spots. The greatest impacts are expected during the Thursday evening commute, when temperatures will be falling most rapidly.
One key uncertainty remains how wet road surfaces will be when temperatures drop below freezing. If pavement remains damp from earlier precipitation, icing could become widespread very quickly, especially on bridges, overpasses, and untreated roads.
Officials warn that flash freezes are especially dangerous because they often occur without heavy snowfall or major winter storms, catching drivers off guard. Motorists are advised to slow down, avoid cruise control, and leave extra distance between vehicles.
Residents are encouraged to check road conditions before heading out Thursday by visiting 511wi.gov or calling 511. Conditions can vary significantly over short distances, particularly during snow squalls.
Temperatures are expected to remain cold into Thursday night, allowing icy conditions to persist even after precipitation ends. Additional forecast updates may be issued as confidence increases.
