AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE WILMINGTON OH
205 PM EDT THU AUG 9 2012

.SYNOPSIS...
A FRONTAL BOUNDARY WILL BE STALLED OVER THE OHIO VALLEY FROM
SOUTHWEST TO NORTHEAST TODAY AND TONIGHT. SURFACE LOW PRESSURE
WILL RIDE ALONG THIS BOUNDARY TONIGHT AND STRENGTHEN AS AN
ENERGETIC UPPER LEVEL LOW CLOSES IN FROM THE NORTHWEST.
SIGNIFICANTLY COOLER AIR WILL BE PULLED IN ON THE NORTHWEST FLOW
AS THE SYSTEM SPINS OVER THE GREAT LAKES REGION FRIDAY AND EXIT
ON SATURDAY.

&&

.NEAR TERM /UNTIL 10 PM THIS EVENING/...
SHOWERS AND THUNDERSTORMS ACROSS THE AREA HAVE BEEN ON A DOWNWARD
TREND THROUGH THE MID MORNING HOURS AS SHORT WAVE ENERGY LIFTS OFF
TO THE NORTHEAST. BASED ON CURRENT TRENDS...WE MAY END UP WITH A
FEW HOUR PERIOD OF LITTLE OF NO PCPN ACROSS OUR AREA. WE ARE
SEEING A FAIR AMOUNT OF BREAKS IN THE CLOUDS THOUGH...ESPECIALLY
ACROSS SOUTHERN PORTIONS OF OUR AREA. THIS SHOULD ALLOW FOR
TEMPERATURES TO REBOUND FAIRLY QUICKLY WITH THE AIRMASS
DESTABILIZING THROUGH THE AFTERNOON HOURS AS ML CAPES PUSH INTO
THE 1500-2000 J/KG RANGE. DEEPENING MID LEVEL TROUGH THROUGH THIS
AFTERNOON AND THE APPROACHING SURFACE LOW SHOULD PROVIDE ENOUGH
FORCING FOR SOME FAIRLY WIDESPREAD REDEVELOPMENT THROUGH THE MID TO
LATE AFTERNOON HOURS...PERSISTING INTO THE EARLY EVENING. BEST
INSTABILITIES SHOULD BE ACROSS THE SOUTH LATER THIS AFTERNOON INTO
THE EARLY EVENING...WHILE THE BETTER DEEP LAYER AND LOWER LAYER
SHEAR WILL BE ACROSS OUR NORTH. WOULD EXPECT THE BEST CHANCE FOR
SEVERE STORMS TO BE NEAR THE NORTHERN GRADIENT OF THE BETTER
INSTABILITY AS THE BETTER SHEAR WORKS SOUTH LATER TODAY...WHICH
LOOKS LIKE IT MAY END UP BEING SOMEWHERE OVER CENTRAL PORTIONS OF
OUR FA. HOWEVER...GIVEN THE DECENT DYNAMICS FOR THIS TIME OF
YEAR...WILL INCLUDE SEVERE WORDING ACROSS THE ENTIRE AREA LATER
THIS AFTERNOON AND EVENING. THE PRIMARY THREAT WILL BE DAMAGING
WINDS...WITH HAIL A SOMEWHAT LESSER THREAT DUE TO THE MOIST
AIRMASS. A FEW ROTATORS WILL ALSO BE POSSIBLE...ESPECIALLY CLOSER
TO THE LOW TRACK ACROSS OUR NORTH.

&&

.SHORT TERM /10 PM THIS EVENING THROUGH SATURDAY NIGHT/...
FORECAST IS EVOLVING AS EXPECTED WITH A SHARPLY AMPLIFYING SURFACE
LOW THIS EVENING AND OVERNIGHT AS THE UPPER LOW STRENGTHENS WHILE
CROSSING EAST THROUGH THE LOWER GREAT LAKES. THE RESULTANT STORMS
ALONG THE SURFACE BOUNDARY WILL MOVE EAST WITH THE ONRUSH OF MUCH
COLDER AIR ON FRIDAY MORNING. HAVE LOWERED THE CHANCE OF RAIN
SIGNIFICANTLY AND QUICKLY WITH THE COMING OF DAYLIGHT ON FRIDAY.
WRAP AROUND SHOWERS ARE A POSSIBILITY WITH THIS SYSTEM...BUT WILL
LACK ANY DEPTH TO PRODUCE THUNDER AND I HAVE REMOVED THUNDER FROM
THE FORECAST BEYOND FRIDAY EVENING AND EXPECT IT WILL BE EVEN
EARLIER IN THE DAY THAT THE NECESSARY INGREDIENTS FOR DEEP
CONVECTION PULL TO THE NORTHEAST.

AN UNUSUALLY - AT LEAST FOR THIS SUMMER - COOL AIRMASS WILL BE
PULLED INTO THE REGION AS THE SYSTEM EXITS. HIGHS WILL BE HARD
PRESSED TO REACH TOO FAR INTO THE 70S ON FRIDAY WITH THE RAINFALL
AND COLD AIR. FRIDAY NIGHTS LOWS IN THE UPPER 50S WILL ALSO BE A
WELCOME RELIEF.

&&

.LONG TERM /SUNDAY THROUGH WEDNESDAY/...
ONLY OTHER FEATURES OF CONCERN FOR THE EXTENDED PERIOD WILL
ARRIVE MONDAY INTO MONDAY NIGHT AS THE GFS BRINGS A DECENT
SHORTWAVE AND SURFACE LOW THROUGH THE REGION. NEITHER FEATURE HAS
BEEN QUITE AS DEVELOPED IN THE PAST TWO ECMWF RUNS AND THUS THE
ECMWF HAS BEEN TRENDING DRY. WENT AHEAD AND INTRODUCED SLIGHT POPS
FOR THIS PERIOD AS THE PAST FEW GFS RUNS HAVE BEEN CONSISTENT AND
THE FEATURES ARE AT LEAST EVIDENT IN THE ECMWF...BUT CONFIDENCE IN
PRECIP IS NOT VERY HIGH AT THIS TIME.

&&

.AVIATION /18Z THURSDAY THROUGH TUESDAY/...
A SPOTTY LINE OF THUNDERSTORMS IS TRYING TO GET GOING ATTM FROM
THE MIAMI VALLEY DOWN INTO SOUTHEAST INDIANA. THIS IS ALONG THE
DEVELOPING INSTABILITY GRADIENT AND WOULD EXPECT THESE
THUNDERSTORMS TO BECOME AT LEAST SOMEWHAT MORE WIDESPREAD THROUGH
MID AFTERNOON AS THEY PROGRESS EAST INTO SOME BETTER INSTABILITY.
IT LOOKS LIKE A BETTER CHANCE OF SHOWERS AND THUNDERSTORMS WILL
THEN MOVE IN FROM THE WEST THROUGH THIS EVENING AHEAD OF THE NEXT
SHORT WAVE. HAVE TRIED TO PINPOINT A FEW HOUR TEMPO GROUP FOR THE
BEST CHANCE OF THUNDERSTORMS. HOWEVER...THE SHOWER AND THUNDERSTORM
THREAT WILL PERSIST THROUGH MUCH OF THE NIGHT...UNTIL THE COLD
FRONT PUSHES EAST OF THE TAF SITES. ON THE BACK SIDE OF THE
FRONT...EXPECT A PERIOD OF MVFR CIGS TO HANG IN THROUGH AT LEAST
MID MORNING FRIDAY. WE COULD ALSO SEE A FEW SHOWERS DEVELOP IN THE
WRAP AROUND MOISTURE FROM LATE MORNING INTO THE AFTERNOON...ESPECIALLY
AT THE NORTHERN TAF SITES.

.OUTLOOK...NO SIGNIFICANT WEATHER EXPECTED.
