NOW...
A DENSE AREA OF FOG HAS MOVED ACROSS PORTIONS OF NORTHERN
ILLINOIS EARLY THIS MORNING...WITH AREAS ALONG AND JUST NORTH OF
INTERSTATE 88 MOST LIKELY TO OBSERVE THE LOWEST VISIBILITIES. MOST
AREAS ARE CURRENTLY OBSERVING VISIBILITIES OF AROUND ONE MILE WITH
SOME LOCALIZED AREAS OBSERVING A HALF MILE OR LESS. TRAVELERS ARE
URGED TO USE CAUTION AS THESE CONDITIONS ARE EXPECTED TO PERSIST
EARLY THIS MORNING BEFORE THEY GRADUALLY IMPROVE LATER TODAY.
