Areas of fog has developed over areas that saw heavier rainfall this past evening. Reduced visibility from fog with some areas seeing 1-3 miles at times will continue into early morning hours. Also cannot rule out isolated pockets of visibility below 1 mile and even patchy dense fog (1/4 mile or less) at times, especially for low-lying areas. May see fog coverage expand overnight. Use caution if traveling in these areas, leaving plenty of space between vehicles and using low-beam headlights as conditions can change quickly.
* AFFECTED AREAS: SAUK ... IOWA ... LAFAYETTE
