Iowa – Near-blizzard conditions may develop across parts of Iowa Wednesday afternoon, as strong winds combine with fresh snowfall, potentially creating dangerous travel conditions.
According to the National Weather Service in Des Moines, light to moderate snowfall will move across the state tonight, followed by another round Wednesday afternoon. Accumulating snow is most likely in northern and northeastern Iowa, where totals of 1 to 3 inches are expected tonight, with up to an additional inch possible Wednesday afternoon.
The primary concern is wind. Forecasts show wind gusts reaching 35 to 50 mph, with locally higher gusts possible Wednesday afternoon and evening. These winds are expected to cause blowing and drifting snow, significantly reducing visibility even where snowfall amounts are relatively light.
Near-blizzard conditions are most likely north of Highway 30, particularly in open and rural areas where powdery snow is already on the ground. Visibility may rapidly drop below safe driving levels during peak wind periods.
Snow is expected to begin this afternoon in northern Iowa, with the first round peaking between 6 p.m. and 9 p.m., ending late tonight. A second round of snow and stronger winds is forecast Wednesday afternoon into the evening.
Commuters, students, and young workers traveling Wednesday afternoon should be prepared for sudden whiteout conditions, especially on north-south roadways prone to crosswinds.
The National Weather Service notes that the blizzard potential for Wednesday has increased, and additional advisories or warnings may be issued as conditions evolve.
