KEY MESSAGE 1)
A STEADY NORTH-NORTHEASTERLY WIND IS STILL NOTICEABLE THIS MORNING AS
THE AREA REMAINS IN BETWEEN THE LOW PRESSURE OFF THE EAST COAST AND
THE BUILDING HIGH PRESSURE OVER THE CENTRAL PLAINS. LOW LEVEL
MOISTURE TRAPPED WITHIN THE COOLER LOW-LEVEL FLOW SUPPORTS A BAND OF
CLOUDS FROM CENTRAL OHIO INTO SOUTHERN OHIO AND NORTHERN KENTUCKY,
DEVELOPING THROUGH MID MORNING AND REMAINING INTO THE AFTERNOON.
OTHERWISE, MOSTLY CLEAR SKIES ARE FORECAST FOR EASTERN INDIANA AND
WESTERN OHIO. TEMPERATURES, WHICH START IN THE 30S AND 40S THIS
MORNING, WILL ONLY CLIMB INTO THE MID 50S, ABOUT 10 TO 15 DEGREES
BELOW NORMAL.
INTO THE LATE AFTERNOON AND EVENING, CLOUDS BEGIN TO CLEAR WITH HIGH
PRESSURE BUILDING IN DIRECTLY OVER THE OHIO VALLEY. CALMING WINDS AND
CLEAR SKIES SUPPORT QUICKLY FALLING TEMPERATURES IN THE EVENING.

AREA. UPPER 20S ARE LIKELY IN THE MORE SHELTERED LOCATIONS. A FREEZE
WARNING IS NOW IN EFFECT. ADDITIONAL FROST IS POSSIBLE SUNDAY NIGHT
