WHAT HAS CHANGED
ADDED RIVER VALLEY FOG FOR TONIGHT, OTHERWISE NOTHING SIGNIFICANT.
KEY MESSAGES
1) A STRETCH OF DRY WEATHER AND SEASONABLY COOL TEMPERATURES CAN BE
EXPECTED THROUGH THE WEEKEND BEFORE TEMPERATURES START TO WARM BACK
UP NEXT WEEK.
DISCUSSION
KEY MESSAGE 1)
DRIER MID LEVEL AIR WILL ADVECT INTO THE REGION FROM EAST TO WEST AND
BREAK UP CLOUD COVER THIS AFTERNOON, STARTING AT THE ISSUANCE OF THIS
PRODUCT IN CENTRAL OHIO AND THEN WORKING ITS WAY WESTWARD, REACHING
THE OH/IN/KY BORDER BY EARLY EVENING. THIS WILL BE THE START OF A
PROLONGED STRETCH OF DRIER WEATHER.
WHILE T/TD SPREAD LOOKS TO BE UNFAVORABLE FOR FOG OVERNIGHT TONIGHT,
THE DRY AIR THAT WILL BE IN PLACE WILL PERMIT RADIATIONAL COOLING
OVER SHELTERED AREAS, IN PARTICULAR RIVER VALLEYS. DO NOT SEE THIS
LASTING LONG OR BEING OVERLY DENSE ATTM, BUT FUTURE SHIFTS WILL NEED
TO LOOK CLOSER AT LATER MODELS TO DISCERN THIS THREAT.
SYNOPTICALLY, THE OHIO VALLEY REMAINS ON THE WESTERN PERIPHERY OF AN
UPPER LEVEL TROUGH, WHICH IS DRIVING THE COOLER/CLOUDIER PATTERN. WE
WILL BEGIN TO SEE A LARGE CUT OFF LOW DEVELOP ALONG THE ATLANTIC
COAST, CREATING A BLOCKING PATTERN THROUGH THE WEEKEND. THIS WILL
RESULT IN A FAIRLY STAGNANT WEATHER PATTERN THROUGH THE NEXT SEVERAL
DAYS, WITH A CONSTANT ADVECTION OF SOME DRIER AIR OUT OF THE NE.
THUS, A MUCH NEEDED STRETCH OF DRIER WEATHER CONDITIONS ARE EXPECTED,
ALONG WITH TEMPERATURES THAT WILL TREND BELOW SEASONAL NORMALS.
AVIATION /13Z THURSDAY THROUGH MONDAY/
VFR CONDITIONS WILL BE FOUND IN CENTRAL OHIO AND CMH/LCK THROUGH THE
FORECAST. LOW MVFR STRATUS IS A FAR CRY BETTER THAN THE IFR CIGS SEEN
THIS MORNING. THIS STRATUS WILL BREAK UP FROM EAST TO WEST, REACHING
ILN/DAY BY NIGHTFALL, AND SHORTLY AFTER NIGHTFALL AT CVG/LUK. ALL
TERMINALS WILL HAVE CLEAR SKIES FOR THE OVERNIGHT PERIOD, TOMORROW,
AND THE NEAR FUTURE.
SURFACE WINDS REMAIN OUT OF THE ENE THROUGH THE TAF PERIOD, GENERALLY
BETWEEN UNDER 8 KTS, LIGHTEST OVERNIGHT.
SOME RIVER VALLEY FOG PRIMARILY IMPACTING KLUK IS POSSIBLE.
