Iowa – Snow bursts race across open fields as strong winds whip loose powder into the air, turning highways white in seconds. The danger comes fast, with visibility dropping sharply during brief but intense snow squalls that can catch drivers off guard.
According to the National Weather Service in Des Moines, a Winter Weather Advisory takes effect from early Friday morning through Friday night across much of central and northern Iowa. Snow showers and snow squalls are expected, with accumulations up to one inch. Wind gusts may reach 40 to 45 mph, strong enough to cause blowing snow and rapid visibility loss.
The biggest concern centers on travel. Snow squalls can create localized whiteout conditions, even where little snow falls. Roads such as Interstate 35, Interstate 80, U.S. Highway 20, and Highway 30 may turn hazardous with little warning. Both the Friday morning and evening commutes are at risk, especially in open rural areas where winds funnel across farmland.
Temperatures hover near freezing, which increases the threat of flash freezing. Melted snow can refreeze quickly, leaving slick pavement behind after squalls pass. Gusty winds may also bring down tree limbs, creating isolated road obstructions or brief power interruptions.
Cities including Des Moines, Ames, Fort Dodge, Mason City, Waterloo, Marshalltown, Carroll, and Algona all fall within the advisory area. Conditions may vary mile by mile, making it hard to judge road safety by appearance alone. Slow down immediately if visibility drops and avoid sudden braking.
Travelers are urged to check road conditions before leaving and monitor updates throughout the day. Conditions may deteriorate quickly during heavier squalls.
