DISCUSSION
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.
TEMPERATURES DROP INTO THE LOWER 30S OVER A LARGE PORTION OF THE
AREA. UPPER 20S ARE LIKELY IN THE MORE SHELTERED LOCATIONS. A FREEZE
WARNING IS NOW IN EFFECT. ADDITIONAL FROST IS POSSIBLE SUNDAY NIGHT
INTO MONDAY MORNING WITH LOWS IN THE MID 30S.
TEMPERATURES BEGIN TO MODERATE EARLY NEXT WEEK AS HIGH TEMPERATURES
CLIMB BACK TO SEASONAL NORMALS ON MONDAY. HIGH PRESSURE CONTINUES TO
DOMINATE THROUGH THE REST OF THE WEEK, PROVIDING DRY CONDITIONS AND
TEMPERATURES SLIGHTLY ABOVE NORMAL (GENERALLY IN THE LOWER 70S).
AVIATION /18Z SATURDAY THROUGH THURSDAY/
A BAND OF MVFR CIGS ASSOCIATED WITH MOISTURE OFF LAKE ERIE CONTINUES
TO SLOWLY SCATTER OUT THIS AFTERNOON. MOST SITES HAVE CLEARED OUT TO
VFR, BUT CAN'T RULE OUT AN OCCASIONAL MVFR CIG THROUGH THE REMAINDER
OF THE AFTERNOON. HIGH PRESSURE WILL LEAD TO CLEAR SKIES AND LIGHT
WINDS OVERNIGHT. THIS COULD RESULT IN SOME RIVER VALLEY FOG POTENTIAL
AT KLUK LATE TONIGHT INTO EARLY SUNDAY MORNING. OTHERWISE, EXPECT
VFR CONDITIONS TO PREVAIL.
AN EXTENDED PERIOD OF LIGHT WINDS AND VFR CONDITIONS FOLLOWS THROUGH
THE REST OF THE WEEKEND AND ALL OF NEXT WEEK.
OUTLOOK...NO SIGNIFICANT WEATHER EXPECTED.
