400 AM EDT WED AUG 11 2004 DISCUSSION

.SHORT TERM (TODAY THROUGH THURSDAY NIGHT)...
SHOWERS AND THUNDERSTORMS FORMED IN THE UNSTABLE AIRMASS ALONG AND
AHEAD OF THE SURFACE FRONT TUESDAY AFTERNOON AND NIGHT. THIS
ACTIVITY WAS EXITING STAGE NORTHEAST AT 330 AM, BUT MORE WILL
REDEVELOP AS WE ENTER ANOTHER DIURNAL CYCLE. WE WILL HAVE A SLIGHT
CHANCE OF SHOWERS AND THUNDERSTORMS OVER THE NORTHWESTERN ZONES
CLIMBING TO LIKELY THIS AFTERNOON INTO EARLY TONIGHT, WITH CHANCE
POPS EVERYWHERE ELSE THIS AFTERNOON AND TONIGHT. SPC PLACES OUR AREA
IN A SLIGHT RISK AND A SEVERE WEATHER OUTLOOK SPSPHI WILL BE ISSUED
TO ADDRESS THIS. OTHERWISE THE FRONT STALLS AS ADVERTISED TONIGHT
AND THURSDAY, SO WE WILL HAVE HIGH CHANCE POPS UNTIL EARLY THURSDAY
NIGHT. SPC ALSO HAS US IN SLIGHT RISK FOR THURSDAY FOR THE SOUTHERN
HALF OF OUR AREA. THIS WILL BE MENTIONED IN THE HAZARDOUS WEATHER
OUTLOOK. IT SEEMS THAT WE WILL HAVE THE SEVERE WEATHER THREAT
COINCIDING WITH A LOCALIZED HEAVY RAIN EVENT FOR A PERIOD OR TWO AS
WE HOOK UP WITH A TROPICAL CONNECTION TO THE DEEP SOUTH. FROM NOW
THROUGH THURSDAY, WE LOOK TO SEGUE INTO A HEAVY RAIN EVENT AS A
CLIMATOLOGICALLY PRIME-TIME LATE SUMMER POTENTIAL FLOOD EVENT
MATERIALIZES, WITH PARALLEL LOW- AND UPPER-LEVEL FLOW WITH GOOD
DYNAMICS AND HIGH MOISTURE CONTENT. SEE THE HYDROLOGY SECTION BELOW
FOR A FEW MORE DETAILS.

&&

.LONG TERM (FRIDAY THROUGH TUESDAY)...
WE START OFF WITH THE HEAVY RAIN THREAT FRIDAY, BUT ANOTHER ROUND IS
POSSIBLE DEPENDING ON WHAT HAPPENS TO THE REMNANTS OF BONNIE LATER
SATURDAY INTO SUNDAY. WE WILL HAVE 50 POPS FOR NOW FOR SATURDAY
INTO SUNDAY, UP FROM DRY, SINCE CONFIDENCE IS NOT THAT HIGH THIS FAR
OUT IN TIME ON TIMING AND TRACK LATER FORECASTERS CAN ADJUST POPS
AS NECESSARY. WILL CONTINUE WITH SHOWER CHANCES INTO EARLY PART OF
THE WEEK, THEN DRY TUESDAY.

&&

.MARINE...
SMALL CRAFT UP THIS PACKAGE FOR SEAS AND INCREASING WINDS FROM LATE
MORNING ON ESPECIALLY CLOSER TO THE BEACH. SCA COULD BE UP FOR
SEVERAL DAYS ESP IF REMNANTS OF BONNIE AND LATER CHARLEY ARE IN THE
VICINITY OF THE COASTAL WATERS. ANY CANYON FISHERMAN MAY WANT TO
CHECK THE WEATHER REAL CLOSE BEFORE HEADING OUT FROM FRIDAY AND OVER
THE WEEKEND. WATER TEMPERATURES CONTINUE TO RUN HIGH. IN FACT FROM
JUNE 1-AUG 9TH CHALLENGING THE TOP SPOT FOR SSTS FOR THE SEASON
SINCE 1912 WITH AN AVERAGE OF 76.1 DEG.

&&

.AVIATION...
LO LVL CAP WILL EXIST THROUGH 8 AM WITH SOME NEAR IFR CONDITIONS BUT
CAP BREAKS SHORTLY AFTER SUNUP AND SKIES W/B PS-SUNNY. ALL AIRPORTS
W/B IN SLGT RISK TODAY WITH THE BEST TIME IN THE AFTERNOON AND
EVENING HOURS. TOPS OF THE HAZE ON TUE WAS 8-9000 FT AND SHUD BE THE
CASE AGAIN TODAY WITH SRNLY WINDS AND NOT QUITE INTO THE TROP AIR
THAT WILL BE SPREADING NORTH TOWARD THE END OF THE WEEKEND.

&&

.HYDROLOGY...
GFS AND ETA AGREE ON TIMING AND STRENGTH OF THE WAVE MOVING
NORTHEAST ALONG THE STATIONARY FRONT WITH LARGE UPPER SUPPORT FROM A
FULL LATITUDE EASTERN TROUGH, WHICH TAPS RICH TROPICAL MOISTURE.
LATER THURSDAY NIGHT AND FRIDAY APPEAR TO BE THE TIME FOR
SIGNIFICANT HEAVY RAIN...PERHAPS 1 TO 3 INCHES ON AVERAGE. WE WILL
ISSUE A HYDROLOGIC OUTLOOK ESFPHI WITH THIS PACKAGE TO ADDRESS THESE
CONCERNS, WHICH SLOSH OVER (PUN INTENDED) INTO THE LONG RANGE. WE
WILL ALSO MENTION THAT MORE HEAVY RAIN IS POSSIBLE OVER THE WEEKEND,
AND INCLUDE THAT IN THE HAZARDOUS WEATHER OUTLOOK FOR GOOD MEASURE
AS WELL.

...SEVERE THUNDERSTORMS POSSIBLE TODAY...

THE STORM PREDICTION CENTER IN NORMAN OKLAHOMA HAS PLACED CHOOSE THE
AREA IN A SLIGHT/MODERATE/HIGH RISK OF SEVERE THUNDERSTORMS FOR LATER
TODAY.

...SCATTERED TO NUMEROUS SHOWERS AND THUNDERSTORMS ARE POSSIBLE THIS
AFTERNOON AND SOME MAY BECOME SEVERE...

THE STORM PREDICTION CENTER IN NORMAN OKLAHOMA HAS FORECAST A SLIGHT
RISK OF SEVERE THUNDERSTORMS FOR OUR AREA FOR TODAY AND TONIGHT,
INCLUDING EASTERN PENNSYLVANIA, NEW JERSEY, THE NORTHEAST MARYLAND
SHORE, AND DELAWARE.

A COLD FRONT WILL MOVE SLOWLY TO THE COAST FROM EASTERN PENNSYLVANIA
TODAY.  SCATTERED TO NUMEROUS THUNDERSTORMS ARE EXPECTED TO FORM IN
THE VERY WARM, HUMID, AND UNSTABLE AIRMASS AHEAD OF THE FRONT.  THE
STORMS ARE ALREADY BEGINNING TO DEVELOP OVER EASTERN PENNSYLVANIA
AND WILL SPREAD EAST AND SOUTH DURING THE AFTERNOON AND EVENING.
ITS ALSO POSSIBLE THAT SOME THUNDERSTORMS COULD FORM CLOSER TO THE
COAST ALONG SEABREEZE BOUNDARIES THIS AFTERNOON.

THE PRIMARY THREATS FROM THESE STORMS ARE DAMAGING WINDS AND LARGE
HAIL. THUNDERSTORMS COULD FORM IN LINES AND CLUSTERS. IN ADDITION,
DUE TO THE CHANGE OF WIND DIRECTION WITH HEIGHT, AN ISOLATED
THUNDERSTORM OR TWO COULD PRODUCE A TORNADO, ESPECIALLY OVER THE
LEHIGH VALLEY AND SOUTHERN POCONOS OF EAST-CENTRAL AND NORTHEASTERN
PENNSYLVANIA, AS WELL AS OVER NORTHWESTERN NEW JERSEY.

ANY OF THE THUNDERSTORMS COULD PRODUCE LOTS OF DANGEROUS LIGHTNING.
AND, DUE TO THE INCREASING HUMIDITY OF THE ATMOSPHERE THROUGH A
DEEP LAYER, SOME THUNDERSTORMS WILL PRODUCE HEAVY RAIN IN A SHORT
PERIOD OF TIME, POSSIBLY AT THE RATE OF ONE OR TWO INCHES IN AN
HOUR, CAUSING STREET AND HIGHWAY FLOODING AS WELL AS FLOODING ON
SOME SMALL CREEKS AND STREAMS.

MOVE INSIDE AT THE FIRST SIGN OF THREATENING WEATHER. THIS COULD BE
AN ACTIVE DAY FOR SEVERE WEATHER IN PARTS OF OUR AREA.

STAY TUNED TO NOAA WEATHER RADIO, YOUR LOCAL RADIO OR TELEVISION
STATIONS OR YOUR CABLE TELEVISION OUTLET FOR FURTHER DETAILS OR
UPDATES. ADDITIONAL WEATHER INFORMATION CAN BE FOUND ON THE INTERNET
AT WWW.WEATHER.GOV/ER/PHI.
