Milwaukee, WI – Wisconsin drivers are being warned of a flash freeze threat this Sunday morning as temperatures dip sharply following Saturday’s snowfall. Meteorologists say melting snow from the day before could quickly refreeze overnight, creating invisible ice on highways such as I-94, I-43, and Highway 41.
According to the National Weather Service, a flash freeze occurs when wet roads freeze within minutes as temperatures plunge below 32°F, often behind a passing cold front. The result can be slick, glassy conditions that catch early-morning travelers by surprise.
Experts warn that on icy roads, a car traveling 35 mph may need up to 600 feet or more to come to a complete stop — nearly the length of two football fields. For comparison, the same vehicle would only need 60–100 feet on dry pavement.
“Even when it’s not snowing, roads can become dangerously icy as temperatures drop,” the NWS said in a Sunday advisory. “Slow down, leave extra space, and avoid cruise control.”
Drivers across southern Wisconsin are urged to give themselves extra time, keep headlights on, and stay alert for black ice on bridges, ramps, and shaded stretches through late morning.
