Patchy areas of dense fog may develop this morning across parts of eastern Iowa and northwest Illinois, especially north of Highway 30.
Visibility could drop to a half mile or less at times, creating potentially hazardous travel conditions for the morning commute.
Drivers in and around communities such as Independence, Manchester, Dubuque, Vinton, Cedar Rapids, Anamosa, Maquoketa, Marengo, Sigourney, Galena, and Freeport should be prepared for sudden changes in visibility over short distances.
Use extra caution on the roads, allow for additional travel time, and keep headlights on low beam to help navigate through any foggy areas.
