AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE WILMINGTON OH
358 PM EDT TUE JUL 12 2011
.SYNOPSIS...
HIGH PRESSURE WILL BUILD INTO THE REGION THROUGH WEDNESDAY...USHERING
IN A COOLER AND DRIER AIRMASS.
&&
.NEAR TERM /UNTIL 6 AM WEDNESDAY MORNING/...
DRIER MID LEVEL AIR/BOUNDARY EVIDENT ON VISIBLE SATELLITE IMAGERY
PUSHING DOWN THROUGH NORTHERN KENTUCKY. THUNDERSTORMS HAVE
DEVELOPED ALONG THIS BOUNDARY JUST SOUTH OF OUR FA THIS AFTERNOON.
WOULD EXPECT ANY REMAINING ACTIVITY TO REMAIN GENERALLY SOUTH OF
OUR AREA ALTHOUGH SUPPOSE A FEW STORMS COULD STILL BRUSH OUR FAR
SOUTHEAST WHERE CU DEVELOPMENT STILL LOOKS A LITTLE MORE IMPRESSIVE
ON SATELLITE. DRIER AIR AT THE SURFACE IS ALSO FILTERING SOUTHWARD
WITH DEWPOINTS NOW DOWN INTO THE 60S ACROSS OUR NORTHERN AREAS.
COMBINATION OF THESE LOWER DEWPOINTS CONTINUING TO PUSH SOUTH AND
SOME OF THE DRIER AIR ALOFT ALSO POSSIBLY MIXING DOWN...SHOULD
ALLOW FOR HEAT INDICES TO SLOWLY DECREASE THROUGH LATE AFTERNOON
AND EARLY EVENING. IN FACT...ADVISORY ACROSS OUR NORTHERN TIER OF
COUNTIES IS MARGINAL AT THIS TIME AND MAY HAVE TO DROP IT EARLY IF
DEWPOINTS CONTINUE TO DECREASE. EXPECT DIURNAL CU TO DISSIPATE THIS
EVENING LEAVING MAINLY CLEAR SKIES. MODELS ARE SHOWING SOME MID
LEVEL MOISTURE OFF TO OUR NORTHWEST WORKING INTO OUR AREA
OVERNIGHT. THIS MAY LEAD TO SOME INCREASE IN CLOUDS LATER
TONIGHT. DRIER AIRMASS FILTERING IN FROM THE NORTH SHOULD ALLOW
FOR OVERNIGHT LOWS RANGING FROM THE LOW 60S NORTHWEST TO LOWER 70S
ACROSS THE FAR SOUTH.
&&
.SHORT TERM /6 AM WEDNESDAY MORNING THROUGH WEDNESDAY NIGHT/...
MID/UPPER LEVEL RIDGING WILL TRY TO PUSH IN FROM THE WEST THROUGH
WEDNESDAY AS SURFACE HIGH PRESSURE MOVES EAST ACROSS THE GREAT
LAKES REGION. THE AIRMASS ACROSS THE AREA WILL REMAIN DRY SO
DESPITE NORTHWEST FLOW PATTERN ALOFT...WILL MAINTAIN A DRY FORECAST
THROUGH WEDNESDAY NIGHT. LOW LEVEL THICKNESS ARE SUPPORTING HIGHS
IN THE UPPER 70S TO LOWER 80S NORTH TO MID 80S ACROSS THE SOUTH
FOR WEDNESDAY.
&&
.LONG TERM /THURSDAY THROUGH TUESDAY/...
HIGH PRESSURE IN THE GREAT LAKES AT THE BEGINNING OF THE PERIOD WILL
SETTLE IN THE MID ATLANTIC AND THEN GET HUNG UP OFF OF THE EAST
COAST NEXT WEEK. THIS WILL LIMIT THE AMOUNT OF CHANGE THAT CAN BE
EXPECTED IN OUR NECK OF THE OHIO VALLEY FOR THIS TIME FRAME OF THE
FORECAST.
STARTING OFF DRY ON THURSDAY...A WEAK INVERTED TROUGH WILL TRY TO
NOSE ITS WAY INTO THE IMMEDIATE OHIO RIVER VALLEY AND NORTHERN
KENTUCKY ON FRIDAY INTO SATURDAY. CANNOT RULE OUT MOISTURE POOLING
ON THE SOUTHEAST SIDE TO POP SOME STORMS...MAINLY LATER FRIDAY INTO
SATURDAY. INITIAL THOUGHT WITH A SOMEWHAT STAGNANT AIRMASS AND
SOUTHERLY COMPONENT TO THE WIND WOULD BE TO SLIGHTLY INCREASE THE
CHANCE OF RAIN EACH DAY BUT SEEING A GENERALLY DRY FORECAST COME
FROM HPC DECIDED TO RUN WITH HPC GUIDANCE AND LEAVE SHOWERS OUT
UNTIL A DISTINCT WEATHER MAKING FEATURE COULD BE FORECAST WITH
SOMEWHAT BETTER CERTAINTY LATER.
&&
.AVIATION /20Z TUESDAY THROUGH SUNDAY/...
SCATTERED TO BROKEN CU HAS DEVELOPED ACROSS THE AREA. A FRONTAL
BOUNDARY IS CURRENTLY BISECTING OHIO FROM SOUTHWEST TO NORTHEAST...
AND MOST OF THE CONVECTIVE ACTIVITY THIS AFTERNOON SHOULD REMAIN
SOUTH OF THE OHIO RIVER. TAF SITES ARE EXPECTED TO REMAIN DRY...
BUT INCLUDED MENTION OF CB FOR KCVG/KLUK AS THUNDERSTORMS MAY PASS
BY JUST SOUTH OF THE AREA.
EXPECTING SCATTERED MID/HIGH CLOUDS TO MOVE IN TONIGHT WITH LIGHT
WINDS. MAY SEE MORE MIST/FOG DEVELOP AROUND 09Z AT MAINLY THE
SOUTHERN TAF SITES. EXPECT GENERALLY MVFR VISIBILITIES WITH
LOCALLY IFR CONDITIONS POSSIBLE AT KLUK. HOWEVER...NORTHERLY WIND
DIRECTION TONIGHT COULD HAMPER MIST/FOG DEVELOPMENT...AS WOULD AN
INCREASE IN CLOUD COVER. QUIET WEATHER IS EXPECTED FOR THE
REMAINDER OF THE TAF PERIOD AS HIGH PRESSURE BRINGS DRIER AIR IN
FROM THE NORTH.
OUTLOOK...NO SIGNIFICANT WEATHER EXPECTED.
