Areas of fog reducing visibility to 1 to 3 miles will blanket the
Bi-state region early this morning. At times, motorists may
experience pockets of dense fog with visibility less than 1/2 mile
at times.
When encountering the fog, especially when observing rapidly
changing visibilities, immediately SLOW down, use your low beam
headlights and allow extra braking distance between you and the
vehicle ahead.
