Des Moines, Iowa – Drivers across central Iowa dealt with dense fog early Saturday, with visibility dropping to under a quarter-mile on major highways including I-80. The National Weather Service advised motorists to slow down, use low beam headlights, and prepare for sudden changes in visibility until conditions improved shortly after sunrise.
According to the National Weather Service in Des Moines, the fog lifted by around 6 a.m. as a cold front moved through from north to south. While patchy fog could still form in low-lying areas early, sunshine is expected to dominate by late morning, with highs near 76 degrees.
Road conditions should improve quickly, but commuters are encouraged to remain cautious on rural highways and near river valleys, where fog tends to settle most persistently. With the front clearing the state, quiet weather will settle in across Iowa through the weekend, offering clear skies and mild air.
Sunday looks especially pleasant, with abundant sunshine and highs in the mid-70s, creating favorable conditions for outdoor activities. Light northwest winds will add to the comfortable stretch. Dry, seasonably mild weather is expected to persist into next week, with highs ranging from the low 70s to upper 70s through Wednesday.
No hazardous weather is expected beyond the morning’s fog, though forecasters caution that early autumn often brings sudden drops in visibility near dawn.
