Iowa and Illinois wake to a curtain of thick fog drifting across fields and highways, softening headlights and dampening pavement as early Thanksgiving travel begins picking up. Visibility drops under a half mile in several counties, and the hazy start encourages drivers to slow down, especially on Highway 30 where pockets of dense fog linger.
According to the National Weather Service, the fog may shift quickly through mid-morning, creating sudden low-visibility zones that challenge commuters. Travelers heading out early should allow extra time and keep low beams on. The air feels crisp but mild for late November, and to be fair, the quiet conditions hide a more active pattern developing for next week.
Models hint at a Winter Tease as colder air pushes into the northern tier before Thanksgiving. Early signs point to the possibility of heavy snow somewhere across the northern U.S. between November 25 and early December. That could affect larger regional travel hubs, and residents in Iowa and Illinois should watch for any change in track or timing. For now, temperatures stay above freezing, keeping any precipitation light and non-wintry.
Saturday brings calmer weather with sunny spells and seasonable highs in the 50s. Light breezes carry a late-fall feel, perfect for outdoor leaf cleanup or early Christmas decorating before colder air returns next week. Sunday stays mild with filtered sun and a touch of warmth ahead of a slight rain chance Monday. Cooler air later next week may open the door to early flakes, though nothing is locked in yet.
