Areas of fog, some locally dense with visibilities under one half mile, can be expected through the morning commute. The fog is in a narrow band roughly 20 miles either side of a line from Genoa Bluff, Iowa to Lanark, Illinois. This band is generally along the Interstate 80 and Highway 30 corridors.
Motorists should exercise caution this morning, especially during the morning commute, as visibilities may change suddenly over very short distances.
This fog is expected to burn off between 9 and 10 AM.
