AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE WILMINGTON OH
201 PM EDT THU AUG 20 2009

.SYNOPSIS...
AN UPPER LEVEL LOW IN THE GREAT LAKES WILL SEE MID LEVEL
DISTURBANCES ROTATE AROUND IT THROUGH THE OHIO VALLEY TODAY AND
TONIGHT. THE LOW TRACKS NORTHEAST AND OUT OF THE AREA LATE
TONIGHT. A SURFACE COLD FRONT WILL CROSS THE OHIO VALLEY FROM
NORTHWEST TO SOUTHEAST ON FRIDAY.

&&

.NEAR TERM /UNTIL 6 PM THIS EVENING/...
REMNANTS FROM OVERNIGHT CONVECTION CONTINUING TO WEAKEN AS IT
PUSHES EAST ACROSS OUR AREA THIS MORNING. HOWEVER...A FAIR AMOUNT
OF CLOUD COVER ASSOCIATED WITH IT HAS ALSO OVERSPREAD THE AREA. THE
EXCEPTION AT THIS POINT IS ACROSS OUR SOUTHEAST WHERE SATELLITE
IMAGES ARE INDICATING A SIGNIFICANT AREA OF CLEAR SKIES. AS A
RESULT...WOULD NOT BE SURPRISED TO SEE A LITTLE BIT OF RE-INTENSIFICATION
IN THE SHOWERS AND THUNDERSTORMS AS THEY MOVE INTO OUR SOUTHEAST
THROUGH EARLY AFTERNOON. BIG QUESTION WILL THEN BE WHETHER OR NOT
WE WILL BE ABLE TO DESTABILIZE LATER THIS AFTERNOON AS WE LOSE SOME
OF THE CLOUDS FROM CURRENT CONVENTION ACROSS THE AREA. EVEN IF
THIS HAPPENS THOUGH...THINK BEST CHANCE FOR ANY REDEVELOPMENT WILL
BE MORE TOWARD THIS EVENING. WILL THEREFORE TRIM BACK POPS SOME
FOR THE TODAY PERIOD...PARTICULARLY IN THE GRIDS.

&&

.SHORT TERM /6 PM THIS EVENING THROUGH SUNDAY NIGHT/...
THERE SHOULD BE AN ACTIVE SYSTEM WORKING NORTHEAST INTO THE
REGION OVERNIGHT...RIDING ALONG THE SW- NE ORIENTED COLD FRONT.
MID LEVEL S/W WILL BE THE PREVAILING INDICATOR OF THE STRONG
STORMS...BUT THE GFS HAS BEEN INDICATING A SURFACE CIRCULATION
UNDERNEATH THE UPPER S/W. IT QUICKLY EXITS NORTHEAST THIS
AFTERNOON WITH RELATIVELY DRY AIR BEHIND IT BY THE LATE DAY AND
EARLY EVENING.

COLD AIR DOES NOT REALLY MAKE IT INTO THE CWA UNTIL OVERNIGHT
FRIDAY...AND COULD SPARK SOME INSTABILITY SHOWERS ON SATURDAY
AFTERNOON WITH THE PASSAGE OF THE UPPER TROUGH. ANY ACTIVITY HERE
SHOULD BE VERY LIGHT AND SCATTERED IN NATURE. TEMPS WILL SEE A
SLIGHT REBOUND ON SUNDAY AS THE HIGH SETTLES OVER THE REGION AND
SUNSHINE SHOULD BE ABUNDANT.

PREVIOUS FORECAST TEMPS AND LATEST GUIDANCE WERE CLOSE TO ONE
ANOTHER AND FIT IN WITH CURRENT THOUGHTS OF UPCOMING SYSTEMS.

&&

.LONG TERM /MONDAY THROUGH WEDNESDAY/...
A COLD FRONT WILL BE CROSSING THE CWA EARLY ON FRI WITH AN UPPER
LEVEL LOW CENTERED NORTH OF THE GREAT LAKES. THE 12Z RUNS OF THE
NAM12/GFS ARE TRENDING SLIGHTLY SLOWER WITH FROPA ON FRI...THUS HAVE
SLOWED THE PROGRESSION OF LIKELY POPS A FEW HRS AT THE BEGINNING
EARLY FRIDAY. WITH GFS ENSEMBLE AND ECMWF IN FAIRLY GOOD
AGREEMENT...FCST IS PRIMARILY BASED OFF THE GFS. BEHIND THE
FRONT...HIGH PRESSURE WILL BUILD IN FROM THE WEST ON SATURDAY. WITH
AN H5 TROF CROSSING THE CWA SAT AFTN...SCHC POPS WERE ADDED ACROSS
THE SERN TWO THIRDS OF THE CWA. THE CWA WILL BE IN A NNWRLY FLOW BY
SUNDAY ON THE ERN PERIPHERY OF A DEEP RIDGE CENTERED ACROSS THE
CNTRL CONUS. RIDGING WILL BUILD IN FROM THE WEST EARLY NEXT
WEEK...ALLOWING FOR DRY AND WARM CONDITIONS TO CONTINUE INTO THE
MIDDLE OF NEXT WEEK. A BROAD AREA OF HIGH PRESSURE WILL BE CENTERED
ACROSS THE MID-ATLANTIC BY TUESDAY...WITH MORE OF A SRLY FLOW
BECOMING DOMINANT AT THE SFC.

FOR TEMPS...CLOUD COVERAGE AND WEAK CAA BEHIND THE FRONT WILL LIMIT
HIGH TEMPS ON FRI TO THE U70S TO L80S. AS THE H5 TROF MOVES EAST OF
THE OH VLY...THE OH VLY WILL MOVE INTO MORE OF A NWRLY FLOW...WITH
HIGHS IN THE MID TO UPPER 70S ON SATURDAY...WITH A FEW LOCATIONS
WARMING INTO THE L80S ACROSS NRN KY AND SW OH ON SUN. AS THE HIGH
MOVES EAST OF THE AREA...TEMPS WILL BECOME PROGRESSIVELY WARMER NEXT
WEEK...IN THE LOW TO MID 80S ON TUES AND WED. OVERNIGHT LOWS WILL BE
COOLER THIS WEEKEND WITH DRIER AIR BUILDING IN AND ALLOW FOR DECENT
RADIATIONAL COOLING...WITH LOWS IN THE MID TO UPPER 50S FRI NIGHT
INTO MON NIGHT. WITH A SRLY FLOW BY MID-WEEK...LOWS WILL BE IN THE
LOWER TO MID 60S TUES AND WED NIGHT.

&&

.AVIATION /18Z THURSDAY THROUGH TUESDAY/...
ISOLATED THUNDERSTORMS BEGINNING TO REDEVELOP ACROSS PARTS OF THE
AREA EARLY THIS AFTERNOON. AS WE CONTINUE TO DESTABILIZE...COVERAGE
SHOULD BECOME MORE WIDESPREAD THROUGH LATE AFTERNOON INTO EARLY
EVENING SO WILL ALLOW FOR A TEMPO TSRA DURING THAT TIME FRAME. WE
COULD THEN SEE A BIT OF A LULL IN PCPN THROUGH THE REST OF THE
EVENING BUT PCPN SHOULD THEN FILL BACK IN AS ACTUAL FRONT MOVES IN
OVERNIGHT. THERE IS STILL SOME LINGERING INSTABILITY OVERNIGHT SO A
FEW THUNDERSTORMS WILL STILL BE POSSIBLE. WILL JUST COVER THAT
THREAT WITH A CB FOR LATER TONIGHT. WIDESPREAD PCPN SHOULD THEN TAPER
OFF LATE TONIGHT INTO FRIDAY MORNING FROM THE NORTHWEST.

OUTLOOK...NO SIGNIFICANT WEATHER EXPECTED.

&&
