If driving, slow down, use your headlights, and leave plenty of distance ahead of you.

Areas of fog have developed across portions of southeastern Iowa into west-central Illinois and could be locally dense with visibilities under a half mile at times. If you are traveling early this morning, be prepared for rapid changes in visibility over short distances and use your low-beam headlights. The fog will dissipate by the mid morning hours.
