Special Weather Statement

Light winds and humid conditions have resulted in areas of fog along the Highway 20 corridor west of Dubuque. The fog could be locally dense at times with visibilities down to a quarter mile, especially in low-lying areas. Expect conditions to quickly improve by 8 AM and afterwards.

Motorists should exercise caution as visibilities may change suddenly over short distances. Use low-beam headlights and leave plenty of distance between you and the vehicle ahead.
