...Patchy Dense Fog Possible Early This Morning...
Areas of fog are developing into far northeast Illinois early this
morning from Wisconsin. Patchy dense fog, with visibilities less
than a half mile, will persist through sunrise across portions of
Lake and McHenry counties, especially north of Route 120. Fog
should gradually lift after sunrise, with improving visibilities.
If heading out early this morning, be alert for rapid changes in
visibility. If you encounter dense fog, slow down, use your low
beam headlights and exercise caution.
