SHORT TERM /THURSDAY NIGHT/
SURFACE HIGH PRESSURE OVER THE GREAT LAKES REMAINS IN PLACE THURSDAY

ABUNDANT CLOUD COVER WHICH LIMITS HIGHS TO THE UPPER 70S FOR MOST
LOCATIONS OUTSIDE OF SOUTHERN OHIO AND NORTHERN KENTUCKY. DEW POINTS
DO NOT DRY OUT MUCH AND STAY IN THE MIDDLE 60S DESPITE NORTHERLY
WINDS. SKIES MAY FINALLY START TO SCATTER MORE LATE THURSDAY
AFTERNOON ALTHOUGH THIS REMAINS FAIRLY UNCERTAIN DUE TO MOISTURE
BEING IN PLACE. WITH WINDS RELAXING THURSDAY NIGHT AND SOME CLEARING
BEING POSSIBLE, FORECAST LOWS DROP A FEW DEGREES COOLER INTO THE
MIDDLE TO LOWER 60S.
LONG TERM /FRIDAY THROUGH WEDNESDAY/
A WEST TO EAST ORIENTED MID LEVEL RIDGE AXIS NOSING INTO THE OHIO
VALLEY WILL WEAKEN THROUGH THE DAY ON FRIDAY. TEMPERATURES WILL BE
SEASONABLE WITH HIGHS IN THE MID TO POSSIBLY UPPER 80S.
AN UPPER LEVEL LOW PRESSURE SYSTEM WILL MOVE ACROSS THE NORTHERN
GREAT LAKES THROUGH THE WEEKEND, HELPING TO CARVE OUT A BROADER
TROUGH ACROSS THE CENTRAL AND EASTERN CONUS HEADING INTO NEXT WEEK.
HIGHS ON SATURDAY WILL RANGE FROM THE MID 80S IN THE NORTHWEST TO
AROUND 90 DEGREES IN OUR FAR SOUTHEAST.
A COLD FRONT ASSOCIATED WITH THE UPPER LEVEL TROUGH WILL MOVE
THROUGH THE AREA SATURDAY NIGHT INTO SUNDAY. MOISTURE IS FAIRLY
LIMITED SO EXPECT ANY SHOWER ACTIVITY TO BE MINIMAL. BEHIND THE COLD
FRONT, A MUCH COOLER AIRMASS WILL SETTLE INTO THE REGION WITH BELOW
NORMAL TEMPERATURES EXPECTED THROUGH THE FIRST PART OF THE WEEK.
HIGHS ON SUNDAY WILL RANGE FROM THE MID 70S NORTHWEST TO THE MID 80S
SOUTHEAST WITH HIGHS MONDAY THROUGH WEDNESDAY ONLY IN THE 70S ACROSS
THE ENTIRE AREA.
AVIATION /00Z THURSDAY THROUGH MONDAY/
COLD ADVECTION AND MVFR CIGS WILL BE THE DOMINANT FEATURE FOR
TERMINALS THIS FORECAST PERIOD. SOME CIGS COULD DROP TO IFR BEFORE
DAYBREAK BUT THIS IS CURRENTLY ONLY NOTED IN THE LUK FORECAST, ALONG
WITH VSBYS BELOW 3SM. IF WINDS ARE STRONGER THAN EXPECTED HERE, THERE
SHOULDN'T BE ANY VSBY RESTRICTIONS BUT ATTM SPEEDS ARE EXPECTED TO BE
UNDER 3KT FOR A FEW HOURS BEFORE DAYBREAK.
A SOLID OVERCAST WILL GIVE WAY TO SOME BREAKS TOMORROW AFTERNOON, AND
THERE COULD BE SOME CLEARING NOTED TOWARDS NIGHTFALL. H8 TEMPS LOOK
TO BE SIMILAR TOMORROW SO MVFR LIFTING TO VFR IS EXPECTED TOWARDS
22-23Z, A LITTLE EARLIER AT CVG/LUK WHERE SLIGHTLY WARMER AIR COULD
BE PRESENT. NORTH WINDS 8-10KT WILL BE FAIRLY UNIFORM THROUGH
TOMORROW, THOUGH CVG AND MORESO LUK STAND TO DROP TO 5-6KT OVERNIGHT.
