WIDESPREAD LIGHT FOG WAS ACROSS NORTH CENTRAL AND NORTHEAST
ILLINOIS THIS EVENING. WHILE VISIBILITY WILL MAINLY BE IN THE ONE
AND ONE HALF TO THREE MILE RANGE...THERE WILL LIKELY BE SOME
LOCALIZED SPOTS OF DENSE FOG WITH VISIBILITY OF ONE HALF MILE OR
LESS.
VISIBILITY OVERALL IS EXPECTED TO IMPROVE OVERNIGHT WITH THE
POTENTIAL FOR LOCALIZED DENSE FOG DECREASING.
BE PREPARED IN CASE YOU HAPPEN TO DRIVE INTO ONE OF THESE DENSE
FOG BANKS. DO NOT FOLLOW THE VEHICLE AHEAD OF YOU TOO CLOSELY AS
YOUR VISIBILITY CAN DROP DRAMATICALLY IN ALMOST AN INSTANT AS YOU
ENCOUNTER THE DENSE FOG PATCH.
