Patchy fog has developed across portions of eastern Iowa and northwest Illinois. The fog could become locally dense with visibilities briefly down to a quarter mile, mainly in river valleys and other low lying locations. Visibilities will quickly improve after 8 AM as temperatures warm up and the fog dissipates. Motorists should exercise caution early this morning as visibilities may change suddenly over very short distances. Slow down and keep plenty of stopping distance in front of you.
