…PATCHY FOG THIS MORNING THROUGH 8 AM CDT…

SOME PATCHY FOG IS BEING REPORTED EARLY THIS MORNING
THROUGHOUT PORTIONS OF CENTRAL AND SOUTHERN IOWA. MANY SITES
ARE REPORTING VISIBILITIES IN THE 2 TO 5 MILES RANGE WITH LIGHT
FOG. HOWEVER A FEW SITES HAVE VISIBILITIES REDUCED TO LESS THAN
ONE MILE AND EVEN NEAR ZERO. THEREFORE BE PREPARED FOR
VISIBILITIES TO BE QUICKLY REDUCED TO NEAR ZERO AT TIMES IN THE
PATCHY FOG…ESPECIALLY IN VALLEYS AND NEAR STREAMS AND OTHER LOW LYING AREAS.
