Special Weather Statement, NWS Philadelphia/Mount Holly

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE MOUNT HOLLY NJ
458 AM EDT SAT JUL 10 2010

.SYNOPSIS...
A COLD FRONT WILL SLOWLY APPROACH THE REGION TODAY...ACCOMPANIED BY
SHOWERS AND THUNDERSTORMS WITH HEAVY RAIN POSSIBLE. LOW PRESSURE
FORMING ON THE FRONT ACROSS THE DELMARVA WILL MOVE NORTHEAST OFF THE
COAST TONIGHT. WEAK HIGH PRESSURE WILL CROSS THE REGION SUNDAY INTO
MONDAY NIGHT. A WARM FRONT WILL APPROACH THE REGION TUESDAY...
BRINGING MORE HOT AND HUMID WEATHER FOR THE MIDDLE OF NEXT WEEK.

&&

.NEAR TERM /UNTIL 6 PM THIS EVENING/...
THE MAIN FORECAST PROBLEM FOR TODAY IS COVERAGE OF CONVECTION AND
THE POTENTIAL FOR FLOODING.

THE AREA OF LOW TOPPED CONVECTION IS FILLING IN AHEAD OF THE
SURFACE COLD FRONT THROUGH THE AXIS OF BEST LOW LEVEL THETA E
EARLY THIS MORNING. STARTING TO SEE A FEW LIGHTNING STRIKES WITH
THE ACTIVITY...MEANING TOPS ARE PROBABLY NOW EXCEEDING 25000 FEET
WITH THE TALLER STORMS. WITH PRECIPITABLE WATER VALUES NEAR 1.8
INCHES IN THIS AREA...THE AIRMASS IS CAPABLE OF PRODUCING
STORMS WITH VERY HEAVY RAINS...AND THE POTENTIAL FOR LOCALIZED
FLOODING.

SHORT TERM GUIDANCE SUGGESTS THAT THE LOW LEVEL THETA E RIDGING
WILL BREAK DOWN TOWARD 1100 UTC...AND START TO BECOME NORTHEAST
SOUTHWEST ORIENTED ACROSS THE NORTHERN ZONES. THROUGH THAT
PERIOD...WILL WATCH FOR THE PRECIPITATION AMOUNTS (WHICH APPEAR TO
BE OVERESTIMATED BY THE KDIX RADAR EARLY THIS MORNING). IF THE
COVERAGE BECOMES LARGE ENOUGH...MAY HAVE TO CONSIDER A SHORT FUSED
FLASH FLOOD WATCH FOR WHAT COMES LATER.

AFTER THIS...THE AIRMASS CHANGE WILL MOVE VERY SLOWLY TO THE EAST
THIS AFTERNOON AND EVENING. AHEAD OF THE COLD FRONT...THE AIRMASS
WILL REMAIN TROPICAL WITH HIGH PRECIPITABLE WATER VALUES AND WARM
CORE SHOWERS AND THUNDERSTORMS. IF THERE IS A BREAK IN THE ACTIVITY
THIS MORNING (IT APPEARS AS THOUGH THERE WILL BE)...WOULD EXPECT
SHOWERS AND LOW TOPPED THUNDERSTORMS TO FILL BACK IN LATER THIS
MORNING AND THIS AFTERNOON.

THE SURFACE FRONT SHOULD ACT AS A FOCUS FOR THE INSTABILITY IN
PLACE. THE EFFECTIVE SHEAR SHOULD REMAIN FAIRLY LOW FOR ALL BUT THE
SOUTHERNMOST ZONES TODAY (AS A MID LEVEL SHORT WAVE MOVES THROUGH
THE FLOW). COUPLE THAT WITH WEAK MID LEVEL LAPSE RATES...AND
ORGANIZED CONVECTION APPEARS TO BE LIMITED. HAVING SAID THAT...A
TROPICAL AIRMASS WITH MOISTURE WELL INTO THE COLUMN COULD LEAD TO
WET MICROBURSTS. HOWEVER...IT IS DIFFICULT TO TELL WHERE THIS MIGHT
BE...SO WILL NOT MENTION ANY SEVERE WEATHER IN THE FORECASTS FOR
TODAY.

THE MAIN CONVECTIVE THREAT WILL BE THE POTENTIAL FOR FLOODING. MORE
ON THIS IN INCLUDED IN THE HYDROLOGY SECTION BELOW. WITH THE AIRMASS
CHANGE SLOW TO OCCUR...WOULD EXPECT HIGHS TO BE CLOSE TO A BLEND OF
MOS NUMBERS FOR TODAY.

&&

.SHORT TERM /6 PM THIS EVENING THROUGH MONDAY/...
ALL MODELS SPIN UP A SURFACE LOW ON THE COLD FRONT ACROSS THE
DELMARVA LATE THIA AFTERNOON AND THIS EVENING. THIS SHOULD HELP THE
FRONT "JUMP" TO THE COAST THIS EVENING. THIS SHOULD ALSO BRING THE
BEST INSTABILITY TO THE COAST AS WELL. NOT AS MUCH FORCING BEHIND
THE FRONT...AND THE LOW LEVELS SHOULD STABILIZE. WILL TRY TO LIMIT
THE MENTION OF SHOWERS AND THUNDERSTORMS TO THE EVENING HOURS...
ESPECIALLY ACROSS THE WEST. CLEARING MAY TAKE SOME TIME AS THE MID
LEVEL REMAIN MOIST MUCH OF THE NIGHT.

COULD BE SOME PATCHY FOG LATE TONIGHT AS THE LOW LEVEL WINDS BECOME
LIGHT AND THE AIRMASS CHANGE TAKES TIME. MAY NOT MENTION IT YET...
SINCE IT IS NOT CLEAR WHERE THE HEAVIEST RAIN WILL FALL TODAY. IN
ANY EVENT...BASED ON THE SLOW AIRMASS CHANGE...WILL SIDE WITH THE
WARMER GFS MOS NUMBERS FOR LOWS.

THE AIRMASS CHANGE WILL BE UNDERWAY SUNDAY MORNING...THEN MAY COME
TO A HALT. ALL MODELS ARE SHOWING POOLING OF PRECIPITABLE WATER
VALUES ACROSS EASTERN ZONES...AS WELL AS A STRIPE OF INSTABILITY
ACROSS CENTRAL ZONES. MODEL SOUNDINGS SUGGEST THAT MID LEVEL CAPPING
SHOULD HOLD DOWN CONVECTIVE POTENTIAL SUNDAY...BUT SINCE THE AIRMASS
CHANGE MAY NEVER ACTUALLY COMPLETE...NOT TOTALLY BUYING THIS. MAY
LEAVE A SLIGHT CHANGE OF SHOWERS AND THUNDERSTORMS ACROSS CENTRAL
ZONES WITH INSTABILITY AND LOW LEVEL CONVERGENCE.

WEAK MID LEVEL WINDS AND WEAKER MID LEVEL LAPSE RATES SUGGEST THAT
CONVECTIVE DEVELOPMENT WOULD ONCE AGAIN BE LOW TOPPED AND HEAVY RAIN
WOULD BE THE MAIN THREAT. SINCE THE CHANCES ARE NOT HIGH ENOUGH...
WILL NOT MENTION ANY ENHANCED POTENTIAL FOR RAIN SUNDAY AFTERNOON.

AT THIS POINT...WITH SOME CONVECTIVE CLOUD COVER POSSIBLE...WILL
SPLIT THE DIFFERENCE BETWEEN MOS NUMBERS FOR HIGHS. 850 MB
TEMPERATURES OF 15 CELSIUS SUGGEST THAT 90 DEGREE IS POSSIBLE AWAY
FROM THE COAST...SO THIS WAS THE TOP NUMBER IN THE GRIDDED FORECAST.

MODEL SOUNDINGS SUGGEST THAT THE MID LEVELS WILL BE CAPPED MONDAY
AFTERNOON (WITH A STRONGER CAP SOUTH AND WEAKER NORTH). WHILE THERE
APPEARS TO BE A STRIPE OF INSTABILITY STRETCHING FROM NORTHEAST
PENNSYLVANIA THROUGH CENTRAL NEW JERSEY...NOT SEEING ENOUGH OF A
FOCUS (OUTSIDE OF A SEA BREEZE) TO RELEASE THE INSTABILITY. SO FOR
NOW...WILL KEEP MONDAY DRY.

850 MB TEMPERATURES ARE A TAD WARMER FOR MONDAY...AND THERE SHOULD
BE LESS IN THE WAY OF CONVECTIVE CLOUDS. SO...THE HIGHER GFS MOS
NUMBERS WERE FAVORED FOR HIGHS.

&&

.LONG TERM /MONDAY NIGHT THROUGH FRIDAY/...
PATTERN FOR THE PHI COUNTY WARNING AREA /CWA/ CONTINUES TO FAVOR
WARMER THAN NORMAL AND HUMID WITHIN THIS PERIOD AND WELL BEYOND /SEE
NAEFS 46 MEMBER GFS/GGEM ENSEMBLE GROUP/.

THE DIFFERENCE FROM EARLIER THIS WEEK IS THAT THE GENERAL FLOW IS
SOUTHWEST THROUGH MOST OF THE COLUMN /INSTEAD OF DRY NORTHERLY/ WHICH
NEGATES THE POTENTIAL FOR DRY EXCESSIVE HEAT BUT DOES OPEN THE DOOR
FOR POCKETS OF HEAVY SHOWERS AND THUNDERSTORMS FOR SHORT PERIODS OF
TIME WITHIN THE OVERALL LONG RANGE PERIOD.

POPULATED THE DATABASE WITH THE 12Z/9 HPC GRIDS AND IN SUMMER...ITS
NOT EASY TO FOCUS THE TIMING WHICH MANY TIMES CAN BE DRIVEN BY
MESOSCALE PROCESSES.

MONDAY NIGHT IS PROBABLY THE MOST NORMAL OF ALL THE NIGHTS WITH
DEWPOINTS JUST STARTING TO RISE FROM THE COMFORTABLE VALUES OF
SUNDAY AND MONDAY AFTERNOONS.

AS THE WEEK MOVES ALONG...DEWPOINTS COULD PERSISTENTLY BE 70 OR
ABOVE FOR THE ENTIRE CALENDER DAY. DID NOT ADD LATE NIGHT-EARLY
MORNING HAZE AND PATCHY FOG IN THE FORECAST /GRIDS ETC/ DURING THE
MIDDLE AND END OF NEXT WEEK BUT ITS SUMMER AND WE SEEM TO BE MOVING
INTO A MORE HUMID PERIOD.

OTHERWISE...DAYTIME HIGHS ARE GOVERNED BY CLOUD COVER AND
OCCURRENCE OF RAIN.  FOR NOW...WITHIN 3 DEGREES OF 90 EACH AFTERNOON
IS FORECAST...80S IN THE HILLY TERRAIN ALONG OUR NW EDGE OF THE
CWA.

&&

.AVIATION /09Z SATURDAY THROUGH WEDNESDAY/...
THE FOLLOWING DISCUSSION IS FOR KPHL, KPNE, KTTN, KABE, KRDG, KILG,
KMIV, KACY AND SURROUNDING AREAS.

A SLOW MOVING FRONTAL SYSTEM AND A WEAK AREA OF LOW PRESSURE MOVING
ALONG IT WILL KEEP VARYING CONDITIONS ACROSS THE AREA TODAY THROUGH
EARLY TONIGHT. AN AREA OF SHOWERS/ISO TSTMS APPROACHING FROM THE
WEST WITH THE FRONT IS WEAKENING...BUT WILL STILL BRING THE CHC FOR
SHOWERS TO THE TAF SITES THIS MORNING. MORE ACTIVITY IS EXPECTED
THIS AFTERNOON ALSO...BUT LOCATION AND TIMING MORE PROBLEMATIC. A
GENERIC 6SM -SHRA VFR/MVFR CIG GROUP WAS USED FOR THE AFTERNOON FOR
NOW. THE LOWER CIGS LIKELY ACROSS THE SRN AREAS...CLOSER TO THE
DEVELOPING WEAK LOW. SLOW TO IMPROVE CONDITIONS THIS EVENING WITH
WINDS SWITCHING AROUND TO N BEHIND THE LOW. LOWER VSBYS AND FOG
EXPECTED IN MOST AREAS...WITH THE DRY AIR NOT EXPECTED TO MIX DOWN
UNTIL SUN.

OUTLOOK...
DRY WEATHER IS EXPECTED TO RETURN FOR THE PERIOD FROM LATER SATURDAY
NIGHT THROUGH MONDAY, WITH A CHANCE OF SHOWERS AND THUNDERSTORMS ON
TUESDAY AND WEDNESDAY. THERE COULD BE SOME LATE NIGHT AND EARLY
MORNING VISIBILITY RESTRICTIONS DURING THE PERIOD.

&&

.MARINE...
A FRONTAL ZONE AND A WEAK LOW WILL KEEP WEAK PRESSURE GRADIENTS ON
THE WATERS TODAY. WINDS WILL GENERALLY BE SOUTH OR SOUTHEAST EARLY
TODAY THEN SLOWLY BACK TO NE THEN NW BY EARLY TONIGHT AS THE LOW
MOVES OFFSHORE. SEAS WILL REMAIN MODEST AROUND 3 OR 4 ON THE OCEAN
FRONT AND 1 TO 2 FT IN THE BAY. NUMEROUS SHOWERS WITH SCATTERED
THUNDERSTORMS ARE EXPECTED. LOCAL HIGHER WINDS AND WAVES...AS
USUAL...WITH ANY THUNDERSTORM.

HIGH PRESSURE MOVES IN FOR SUN AND THEN MOVES EAST MON. ANOTHER
LOW/FRONT APPROACH TUE AND REMAINS FOR WED. THE FEATURES DO NOT LOOK
STRONG ENOUGH AT THIS POINT TO CAUSE ANY SCA CONDITIONS...BUT THINGS
MAY CHANGE BEFORE THEN. MORE SHOWERS/TSTMS WILL ACCOMPANY THE NEXT
SYSTEM...SO PLAN ACCORDINGLY.

&&

.HYDROLOGY...
RAINFALL DURING THE EVENING AND EARLY OVERNIGHT HOURS HAS BEEN
MAINLY CONFINED TO THE WESTERN ZONES AND NORTHWEST NEW JERSEY. TO
THIS POINT...RAINFALL AMOUNTS HAVE GENERALLY BEEN LESS THAN AN INCH.

THERE ARE MIXED SIGNALS AS TO WHETHER THE AREA WILL NEED A FLASH
FLOOD WATCH FOR TODAY. A SLOW MOVING FRONT (ACTING AS A FOCUS) AND
WARM...LOW TOPPED CONVECTION WITH PRECIPITABLE WATER VALUES TWO
STANDARD DEVIATIONS ABOVE NORMAL FOR JULY SUGGEST THAT 1 TO 3 INCHES
OF RAIN IS POSSIBLE WITH SLOW MOVING SHOWERS AND THUNDERSTORMS.

THE PROBLEM WILL BE COVERAGE. GETTING A LULL SO FAR THIS MORNING...
WITH THE BEST ACTIVITY ACROSS EAST CENTRAL PENNSYLVANIA MOVING
NORTHEAST. IT APPEARS AS THOUGH THIS ACTIVITY WILL REMAIN NORTH AND
WEST OF THE AREA THROUGH 1200 UTC. AFTER THIS...THE FOCUS APPEARS TO
SPLIT BETWEEN NORTHERN AREAS (WHERE THE BEST MID LEVEL FORCING SHOULD
BE) AND THE SOUTHERN AREAS (WHERE THE BEST INSTABILITY SHOULD BE).

AT THIS POINT...IT APPEARS AS THOUGH SOUTHERN AREAS MAY END UP WITH
THE GREATER THREAT...AS LOW LEVEL THETA E RIDGING POINTS TO EASTERN
MARYLAND...DELAWARE AND SOUTHERN NEW JERSEY. THIS IS ROUGHLY THE
PATH OF A SURFACE WAVE RIDING UP THE SURFACE COLD FRONT THIS
AFTERNOON AND EVENING. THESE AREAS ARE MOSTLY SANDY SOIL WITH HIGH
FLASH FLOOD GUIDANCE NUMBERS. WHILE THE THREAT FOR LOCALIZED
FLOODING IS THERE WITH INSTABILITY AND HIGH PRECIPITABLE WATER
VALUES...ANTECEDENT DRY CONDITIONS LEAVE CONFIDENCE BELOW THAT
NEEDED FOR A FLASH FLOOD WATCH. THUS...WILL HOLD OFF ON A WATCH FOR
NOW AND CONTINUE TO MONITOR TRENDS.

&&

.TIDES/COASTAL FLOODING...
THE PREVIOUS HIGH TIDE ALONG THE DEL BAY AND RIVER ENDED UP JUST
SHORT OF MINOR TIDAL FLOODING. DEPARTURES WILL REMAIN ELEVATED WITH
THE UPCOMING NEW MOON...SO WE WILL KEEP AN EYE ON THE TIDES OVER THE
WEEKEND WITH THE ASTRONOMICAL HIGH TIDES BEING QUITE HIGH.
DEPARTURES OF LESS THAN A HALF FOOT WILL PRODUCE MINOR TIDAL
FLOODING ON THE OCEANFRONT AND ON DELAWARE BAY. THE HIGH TIDES OF
CONCERN ARE THOSE IN THE EVENING ON SUNDAY, MONDAY AND TUESDAY, WITH
MONDAY BEING THE HIGHEST OF THE THREE.

&&

.RIP CURRENTS...
LOCAL FCST SCHEME PRODUCES LOW RISK FOR RIP CURRENTS TODAY WITH
WAVES IN THE SURF ZONE 3 TO 4 FT.

&&

.PHI WATCHES/WARNINGS/ADVISORIES...
PA...NONE.
NJ...NONE.
