Des Moines, IA – A Dense Fog Advisory remains in effect until 9 a.m. Monday, as visibility drops to less than a quarter mile across portions of Iowa. Drivers should use caution on roadways, particularly on highways such as I-80 and I-35, where reduced visibility could cause hazardous travel conditions during the morning commute.
According to the National Weather Service, dense fog will clear west to east by mid-morning as skies gradually turn partly sunny. Winds will increase throughout the day, becoming breezy from the west at 15 to 30 mph, with gusts adding an extra chill to the 40–50°F highs expected by the afternoon.
The rest of the week brings fluctuating temperatures and potential for rain and snow, particularly on Tuesday and Thursday. On Tuesday, a 30–40% chance of light rain or snow mix will develop, mainly across northern Iowa, as highs climb to a milder 32–45°F. By Wednesday, colder conditions will take hold, with highs dipping into the 20s to low 30s and lows dropping to the teens.
Thursday brings renewed precipitation chances as a stronger weather system moves through the state. Rain or snow is possible across portions of Iowa, requiring close monitoring for potential travel impacts later in the week. Highs on Thursday could range from 34–46°F before colder air returns Friday, with temperatures falling to 20–30°F under partly cloudy skies and windy conditions.
Residents are urged to stay weather-aware and check for updates, especially regarding dense fog, freezing precipitation, and changing road conditions. Motorists should slow down, use headlights, and allow for extra stopping distance when visibility is reduced.
