...PATCHY DENSE FOG WILL AFFECT TRAVEL OVER WEST CENTRAL ILLINOIS
EARLY THIS MORNING...

Patchy dense fog has formed across west central Illinois in the last
couple of hours. Visibility may fall below one-quarter mile at times
through early morning, leading to potentially hazardous travel
conditions.

Expect rapid changes in visibility over short distances, with visibility
possibly even near zero at times.

Be sure to slow down if you encounter dense fog. Use low beam headlights if
driving, and leave plenty of distance between you and the vehicle ahead.
