Special Weather Statement, NWS Philadelphia/Mount Holly

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE MOUNT HOLLY NJ
845 PM EDT TUE APR 12 2011

.SYNOPSIS...
LOW PRESSURE OVER VIRGINIA TONIGHT WILL TRACK SLOWLY NORTHEASTWARD
AND REACH THE NEW JERSEY COAST LATER WEDNESDAY BEFORE HEADING
TOWARD NEW ENGLAND. HIGH PRESSURE WILL BUILD IN BEHIND THE LOW FOR
THE END OF THE WEEK. LOW PRESSURE OVER THE GREAT LAKES WILL MOVE
INTO NEW ENGLAND THIS WEEKEND, FOLLOWED BY A HIGH PRESSURE SYSTEM
FOR MONDAY. A WEAK COLD FRONT SHOULD MOVE THROUGH THE AREA ABOUT
TUESDAY.

&&

.NEAR TERM /UNTIL 6 AM WEDNESDAY MORNING/...
THE CONVECTION WAS JUST ABOUT OUT OF OUR NORTHEASTERN AREAS AT
00Z...AND RAIN HAD TAPERED DOWN. HOWEVER, MORE RAIN IS EXPECTED
LATER THIS EVENING AND INTO THE OVERNIGHT PERIOD...MINUS MOST OF
THE CONVECTION...AS MORE MOISTURE WILL BE CIRCULATING NORTHWARD IN
ADVANCE OF THE APPROACHING LOW PRESSURE SYSTEM. ISOLATED
CONVECTION WAS LIMITED IN THE GRIDS TO OUR SOUTHEASTERN ZONES
EARLY TONIGHT...CLOSER TO THE WEAK CAPE AND INSTABILITY ALOFT.

THE INCREASING ONSHORE FLOW WILL TAKE THE PLACE OF THE CONVECTION
TONIGHT. THE FAVORED FORCING TONIGHT IS MORE OVER NEW JERSEY AND
POSSIBLY THE POCONOS THAT HAD LESS RAIN AND A BIGGER BREAK. MORE
IN THE HYDRO SECTION BELOW, BUT WE ARE NOT ENVISIONING ANY STREAM
FLOODING.

AS FAR AS THE WINDS GO, THE WRF-NMM HAS COOLED ITSELF SLIGHTLY
FROM YESTERDAY AS NONE OF ITS MOMENTUM TRANSFER WINDS REACH WIND
ADVISORY CRITERIA TONIGHT. PART OF THE REASON IS THE FCST SFC LOW
PRESSURE IS WEAKER THAN YESTERDAY AND THE LOW ITSELF IS FORECAST
TO WEAKEN AS IT APPROACHES THE COAST. THIS DOES SEEM LOGICAL AS
THE DRY AIR HAS WRAPPED PRETTY DEEPLY AROUND THE 500MB LOW. THE
GFS HAS BEEN MORE SUBDUED ALL ALONG. NOT A TEXTBOOK CASE, BUT A
LOCAL DEVELOPED NOR'EASTER CHECK LIST BASED ON THE FCST PRESSURE
GRADIENT FALLS JUST SHORT OF ADVISORY CRITERIA.

STAT GUIDANCE TEMPS ARE PRETTY CLOSE AND SEEMED REASONABLE.

&&

.SHORT TERM /6 AM WEDNESDAY MORNING THROUGH FRIDAY/...
WHILE THE SYNOPTIC SCALE FORCING WILL BE DONE COME WEDNESDAY
MORNING, THE CLOSED LOW WILL STILL HAVE TO MOVE THROUGH OUR CWA.
SELF DESTRUCT SUNSHINE, IF IT CAN OCCUR AT ALL FOR US, HAPPENED
TODAY IN WV/KY AND TN. THIS SHOULD BE OUR WED OUTCOME. THE GFS
GOES AS FAR AS TO FORECAST SOME SFC BASED CAPES, BUT ITS SFC DEW
POINT FCSTS PRE PRECIPITATION APPEAR 5 TO 10F TOO HIGH. WITH THE
LOW FREEZING LEVEL IN SPITE OF THE LACK OF ELECTRIFICATION WOULD
NOT BE SHOCKING TO MAYBE HAVE SOME SMALL HAIL. NOT TOO MANY
CHANGES WERE MADE TO THE FORECAST WITH THE HIGHEST POPS IN THE
NORTHERN HALF OF OUR CWA. MAX TEMPS WERE A STAT GUIDANCE BLEND
WHICH TAKES INTO ACCOUNT SOME UPSIDE TEMP POTENTIAL BETWEEN THE
SHRAS.

WE FOLLOWED THE FASTER GFS/UKMET SOLUTION VS THE NAM TO END SHRAS
CHANCES ON WEDNESDAY NIGHT. THIS FOLLOWS THE GENERAL TREND OF THE
PREVIOUS FORECAST WITH HIGHEST POPS NE CLOSEST TO THE CLOSED LOW AND
NOT MUCH OF A CHANCE AFTER MIDNIGHT. STAT GUIDANCE WAS CLOSE AGAIN
AND WAS USED. NOT SURE IF SKIES WILL CLEAR IN TIME SOUTH FOR SOME
RADIATIONAL COOLING, ALTHOUGH WE DID HEDGE IT THAT WAY.

IMPROVING CONDITIONS ON THURSDAY WITH STRONG RIDGING FORECAST TO
OCCUR. CLOUDS SHOULD CLEAR QUICKLY IF NOT GONE BY MORNING. WE
WENT WITH THE HIGHER STAT GUIDANCE FOR MAX TEMPS BECAUSE OF THE
EXPECTED SUNSHINE.

A WEAK FRONTAL BOUNDARY/TROF SHOULD PASS THROUGH OUR CWA ON THURSDAY
NIGHT. THIS MARKS THE DIFFERENCE IN AIR MASSES BETWEEN THE CANADIAN
HIGH PRESSURE SYSTEM AND THURSDAY'S HIGH TO THE SOUTH. IT ALSO
SHOULD BRING SOME MID TO HIGH LEVEL CLOUDS MAINLY ACROSS THE
NORTHERN PART OF OUR CWA THURSDAY NIGHT. A SLIGHTLY COOLER DAY
(NOT AS COOL AS MEX MOS WHICH GIVES TOO MUCH CREDIT TO ONSHORE
FLOW WRN HALF OF OUR CWA) IS FORECAST FRIDAY BECAUSE OF THIS
CANADIAN HIGH AND THE ONSHORE FLOW. THE 500MB RIDGING IS FORECAST
TO BE WEST OF OUR CWA THRU 00Z, SO NO PCPN IS EXPECTED TO REACH US
ON FRIDAY DAY.

&&

.LONG TERM /FRIDAY NIGHT THROUGH TUESDAY/...
THERE WILL BE ANOTHER PRECIPITATION EVENT THIS WEEKEND...PROBABLY
SATURDAY AFTERNOON AND NIGHT AND THEREAFTER STILL SOME UNCERTAINTY
IN THE THERMAL ADVECTION PATTERNS EARLY NEXT WEEK HERE.

THE 12Z/12 HPC GUIDANCE WAS USED AS THE BASELINE FOR THIS FORECAST.

THE 12Z GEFS WAS SIGNIFICANTLY FASTER THAN THE 12Z ECMWF. SLOWED
THE GEFS ONSET OF THE QPF...TILL SOMETIME SATURDAY MORNING. THE
18Z GFS OP RUN SLOWED DOWN AS WELL.

POPS CONTINUE HIGH /NOW RAISED TO CATEGORICAL/ FOR AN EVENT SATURDAY
AFTERNOON/EVENING DUE TO THE GENERAL MODEL MESSAGE OF A SE INFLOW
EVENT AS A STRONG TROUGH ALOFT WEAKENS EASTWARD INTO THE NORTHEAST
USA.

THE ECMWF STILL LOOKS RATHER COLD SATURDAY BUT AM TOSSING THE IDEA
OF SNOW AT THE START. NOT IMPOSSIBLE BUT NOT REALLY WORTH THE
MENTION.

THE ESSENCE OF THE DAILIES BELOW...

SATURDAY...LOOKS RAINY AT LEAST PART OF THE DAY WITH A BRISK IF
NOT VERY WINDY ESE INFLOW ALONG THE COAST. COULD BE A COLD RAW
DAMP AFTERNOON. CONFIDENCE ABOVE AVERAGE. GUST MAY REACH 45 MPH
ALONG THE COAST IN THE AFTERNOON. CONFIDENCE ON TEMPS AND WIND AS
FORECAST IS BELOW AVERAGE.

SUNDAY...DRIES OUT AND SHOULD BE A DECENT DAY HERE.  FORECAST
TEMPERATURE SPREAD IS TIGHTLY CLUSTERED AND CONFIDENCE ON THE
TEMPERATURE OUTCOME IS ABOVE AVERAGE.

MONDAY/TUESDAY...NO BIG STORM BUT THERE COULD BE A DECENT FRONTAL
SYSTEM FORMING IN THE AREA. DIFFERING SOLUTIONS AND CONFIDENCE ON
THE OUTCOME OF THESE TWO DAYS IS LESS THAN AVERAGE.  SMALL CHANCE OF
SHOWERS AND TEMPERATURE SOLUTIONS SEEM TO HAVE LARGE SPREAD.

SUPPORT FOR THIS CONFIDENCE INFORMATION IS LINKED TO

&&

.AVIATION /01Z WEDNESDAY THROUGH SUNDAY/...
THE FOLLOWING DISCUSSION IS FOR KPHL, KPNE, KTTN, KABE, KRDG, KILG,
KMIV, KACY AND SURROUNDING AREAS.

TONIGHT...VFR/MVFR CIGS PREVAIL GENERALLY BETWEEN 1100-5000 FT.
NE GUSTS 20-30KTS...MAINLY NJ AND DEL. AS LOW PRES ARRIVES IN THE
AREA...WINDS WILL EASE FROM SOUTH TO NORTH DURING THE NIGHT AND
CIGS/VSBY SHOULD LOWER TO IFR AS SOMEWHAT WARMER AIR JUST ABOVE
THE GROUND ARRIVES TOWARD MORNING.

WEDNESDAY...CONDS GRADUALLY IMPROVE TO MVFR CIGS FORENOON WITH POSSIBLE
SLOW MOVING HEAVY CONVECTION MIDDAY INTO MID AFTERNOON. LESS WIND THAN
THAT OF LATE THIS PAST TUESDAY AFTERNOON.

.OUTLOOK...
WEDNESDAY THROUGH FRIDAY...VFR CONDITIONS TO RETURN WEDNESDAY NIGHT AND
PERSIST THROUGH FRIDAY AS HIGH PRESSURE MOVES INTO OUR REGION.

SATURDAY...CONDITIONS SHOULD LOWER TO MVFR IN SHOWERS DURING THE
AFTERNOON/EVENING WITH LLWS POTENTIAL ASSOCIATED WITH A STRENGTHENING
SOUTHEASTERLY LOW LEVEL JET.

&&

.MARINE...
8 PM MARINE UPDATE WAS WITH VERY LITTLE CHANGE. WE MAY CANCEL THE
DEL BAY OF THE SCA A LITTLE SOONER THAN 6 AM WED.

LOW PRESSURE OVER VIRGINIA WILL SLOWLY TO THE COAST TONIGHT AND
THEN UP ALONG OUR WATERS WEDNESDAY. IT WILL BRING INCREASING WINDS
AND CHOPPY SEAS TO THE WATERS. GUSTS WILL LIKELY REMAIN AROUND 30
TO 35 KNOTS FOR THE MOST PART...SO THE SCA FLAG WILL BE KEPT WITH
THE PACKAGE WITH A MENTION OF A FEW GUSTS TO 35 KNOTS.

THERE IS ONLY LOW CONFIDENCE IN CONSISTENT GALE CONDITIONS ON THE
WATERS TONIGHT. WINDS ON THE BAY WILL SUBSIDE BY WED MORNING...SO
THE SCA FLAG WILL COME DOWN THERE FIRST. THE SCA FOR THE OCEAN
WILL GO LONGER SINCE THE SEAS WILL SUBSIDE SLOWER.

HIGH PRESSURE WILL BE IN CONTROL OF THE WEATHER WED NIGHT THROUGH
FRI NIGHT. ANOTHER LOW WILL MOVE WELL WEST OF THE REGION SAT AND
SUN. A FRONT ASSOCIATED WITH THIS LOW WILL CROSS THE WATERS...WITH
POSSIBLE WAVE DEVELOPMENT ALONG IT SAT AND SUN. MORE SCA CONDITIONS
ARE POSSIBLE THEN.

&&

.HYDROLOGY...
RAINFALL TODAY THROUGH 8 PM...AMOUNTS IN EXCESS OF 1 INCH BELOW.
NO ASOS/AWOS EXCEEDED 1 INCH SO FAR IN OUR CWA.

FEDERALSBURG IN CAROLINA COUNTY MD RECORDED 1.5 INCHES LATE TODAY.
NEWPORT IN CUMBERLAND COUNTY NJ 1.1 INCHES LATE TODAY AND
POTTERSVILLE IN SOMERSET COUNTY NJ 1.18
STOCKTON IN HUNTERDON COUNTY NJ 1.06
IRONIA IN MORRIS COUNTY NJ 1.02

THE BIG CONCERN FOR HEAVY RAIN INTO EARLY TONIGHT HAS
EVAPORATED...AS THE MAIN THRUST OF CONVECTION HAS MOVED TO THE
NORTHEAST. RAIN AMOUNTS WERE A HALF TO ONE INCH THIS AFTERNOON
INTO THIS EVENING...WITH LOCAL AMOUNTS BETWEEN 1 AND 1.75 INCHES
IN THE CONVECTIVE BANDS. OTHER THAN SOME STREAM RISES AND LIKELY
LOCALIZED PONDING ON ROADS...NO HYDROLOGIC PROBLEMS HAVE BEEN
OBSERVED OR REPORTED.

RAIN HAD BECOME SPOTTY AS OF 00Z...BUT MORE RAIN OVERNIGHT WILL
ADD TO THE ANTECEDENT PRECIPITATION. AT THIS TIMES ADDITIONAL
AMOUNTS OF 1/3 TO 2/3 INCHES...LOCALLY 1 INCH...WOULD APPEAR TO
REMAIN JUST BELOW THE LOWER END OF THE HEADWATER GUIDANCE NUMBERS
FOR THIS AREA. THERE WAS NOT MUCH OF A HYDROLOGIC RESPONSE TO THE
RAIN ON THE 8TH IN MUCH OF THE AREA...SO WE DO NOT APPEAR TO BE
OVERLY SUSCEPTIBLE TO FLOODING. THE RAINFALL AMOUNTS ABOVE SUGGEST
POOR DRAINAGE AND NUISANCE FLOODING...AND GIVEN THE REASONING
ABOVE WILL HOLD OFF ON A FLOOD WATCH. NONE OF THE 00Z MMEFS
ENSEMBLE MEMBERS BRING FORECAST RIVER POINT GAGES TO FLOOD STAGE.

&&

.TIDES/COASTAL FLOODING...
A MINOR COASTAL INUNDATION FLOOD EVENT IS POSSIBLE WITH THE SATURDAY
EARLY EVENING HIGH TIDE CYCLE...ESP NJ AND POSSIBLY UPPER DEL BAY
REEDY PT TO PHL WITH THE SAT NIGHT AROUND MIDNIGHT HIGH TIDE CYCLE.

&&

.PHI WATCHES/WARNINGS/ADVISORIES...
PA...NONE.
NJ...NONE.
DE...NONE.
MD...NONE.
MARINE...SMALL CRAFT ADVISORY UNTIL 6 AM EDT THURSDAY FOR ANZ450>455.
     SMALL CRAFT ADVISORY UNTIL 6 AM EDT WEDNESDAY FOR ANZ430-431.
