EARLY MORNING SATELLITE IMAGERY SHOWS MOSTLY CLEAR SKIES ACROSS THE
REGION. A FEW MID-LEVEL CLOUDS WERE MOVING THROUGH SOUTHERN INDIANA
AND FAR NORTHERN KENTUCKY. GOES NIGHT-TIME FOG PRODUCT IS SHOWING
WIDESPREAD VALLEY FOG ACROSS OUR SOUTHEAST SECTIONS. CURRENT
TEMPERATURES ACROSS THE REGION WERE IN THE UPPER 40S TO THE LOWER
50S.
WHILE NO SIGNIFICANT WEATHER IS EXPECTED THROUGH DAWN, LOCALLY DENSE
FOG WILL BE POSSIBLE IN AREAS ALONG AND SOUTHEAST OF A LINE FROM
ROUGHLY BOWLING GREEN TO WINCHESTER. THE FOG WILL BE MOST DENSE IN
THE RIVER VALLEYS, LOW-LYING AREAS, AND OVER BODIES OF WATER. A
DENSE FOG ADVISORY WILL BE FORTHCOMING WITH THE FORECAST ACROSS OUR
SOUTHEASTERN SECTIONS. OVERNIGHT LOWS WILL BE IN THE UPPER 40S/LOWER
50S. LEXINGTON STILL LOOKS TO TIE OR POSSIBLY BREAK THEIR RECORD
