The local office's own words before this special weather statement went out, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.
NWS Philadelphia/Mount Holly wrote its last area forecast discussion before this special weather statement went out at Jul 23, 9:26 PM EDT, 1 hour 13 minutes earlier.
Area forecast discussion, Jul 23, 9:26 PM EDT, 1 hour 13 minutes before
AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE MOUNT HOLLY NJ
926 PM EDT FRI JUL 23 2010
.SYNOPSIS...
BERMUDA HIGH PRESSURE TO THE SOUTHEAST WILL CONTINUE TO BRING HOT
AND HUMID AIR INTO THE REGION THROUGH THE FIRST PART OF THE
WEEKEND, WHILE MID LEVEL TROUGHS MOVE BY TO THE NORTH. A COLD
FRONT WILL DROP INTO THE REGION ON SUNDAY, AND HIGH PRESSURE WILL
BUILD IN FOR THE NEW WEEK.
&&
.NEAR TERM /UNTIL 6 AM SATURDAY MORNING/...
THE SUPERCELL THAT PROMPTED THE SEVERE THUNDERSTORM AND TORNADO
WARNINGS HAS EXITED THE AREA...SO THE TORNADO WATCH HAS BEEN
DROPPED. STILL SEEING SOME ACTIVITY UPSTREAM...BUT MORE IMPRESSIVE
ACTION ACROSS LAKE ERIE AND NORTHWEST PENNSYLVANIA. THIS WOULD
TAKE A WHILE TO REACH OUR AREA...SO WILL KEEP A MENTION OF SHOWERS
AND THUNDERSTORMS OVER.
OTHERWISE...LITTLE CHANGE IN LOW TEMPERATURES OVERNIGHT AS THE
AIRMASS WILL COOL VERY SLOWLY WITH THE AMOUNT OF MOISTURE IN THE
AREA.
&&
.SHORT TERM /6 AM SATURDAY MORNING THROUGH MONDAY/...
PER THE MODELS, A MID LEVEL VORT MAX EXITS TO THE NORTHEAST
TOMORROW MORNING, THEN ANOTHER ONE APPROACHES FROM THE NORTHWEST
TOMORROW AFTERNOON, THEN ANOTHER ONE APPROACHES TOMORROW NIGHT. ON
SUNDAY, THE AXIS OF THE MID LEVEL TROUGH EMANATING FROM THE VORTEX
OVER EASTERN CANADA FINALLY PUSHES INTO THE AREA AND THE
ASSOCIATED SURFACE COLD FRONT FOLLOWS SUIT. NORMALLY, WE WOULD
BE FOCUSING THE CHANCES OF CONVECTION AROUND THE AFTERNOON AND
EVENING, BUT THE POSSIBLE TIMING OF THE IMPULSES MAKE US SHY AWAY
FROM THAT. THERE IS PLENTY OF MOISTURE AND INSTABILITY AVAILABLE
FOR CONVECTION AT ANY TIME /AT NIGHT, WE NEED THE FORCING TO TAP
INSTABILITY ABOVE THE SURFACE, BUT THE IMPULSES MAY PROVIDE THAT/.
WE THINK THE SURFACE FRONT WILL BE FAR ENOUGH THROUGH OUR AREA TO
CHANGE THE AIR MASS BY SUNDAY NIGHT, WHEN WE DROP THE CHANCES OF
CONVECTION FOR THE REST OF THE SHORT TERM.
FROM SATURDAY THROUGH SATURDAY NIGHT, WE EXPECT NO CHANGE IN THE
AIR MASS WITH AN OPPRESSIVE SATURDAY AND A VERY UNCOMFORTABLE
SATURDAY NIGHT. THE ADVISORY AND WARNING RUN THROUGH SATURDAY FOR
NOW, AND MAY BE EXTENDED SUBSEQUENTLY. WE EXPECT SOME RELIEF TO
BEGIN TO MOVE IN FROM THE NORTHWEST STARTING SUNDAY, WITH
TEMPERATURES CLOSER TO NORMAL ON SUNDAY NIGHT AND MONDAY. WE HAVE
GONE FOR THE HIGHER STAT GUIDANCE TEMPERATURES THROUGH SATURDAY
NIGHT PER CONTINUITY AND H925 TEMPERATURES, THEN WE HAVE MOVED
TOWARD A COMPROMISE FROM SUNDAY ONWARD.
&&
.LONG TERM /MONDAY NIGHT THROUGH FRIDAY/...
THE MID LEVEL NORTHWEST FLOW SHOULD KEEP CONDITIONS DRY MONDAY NIGHT
AND TUESDAY AS WEAK HIGH PRESSURE CROSSES THE REGION. DEW POINTS
SHOULD REMAIN FAIRLY LOW THROUGH THE PERIOD AS THE COLD FRONT THAT
CROSSES THE AREA SUNDAY BECOMES STATIONARY SOUTHWEST OF THE AREA.
MOISTURE WILL TRY TO OVERRUN THAT BOUNDARY TUESDAY NIGHT INTO
WEDNESDAY AS WARMER AIR IN THE LOW TO MID LEVEL TRIES TO COME BACK
INTO THE REGION. AT THIS POINT...IT APPEARS AS THOUGH THE WARM FRONT
WILL WAIT UNTIL WEDNESDAY EVENING TO COMES THROUGH THE REGION...SO
WE ARE PROBABLY LOOKING LIKE A PRE WARM FRONTAL SHOWERS AND
THUNDERSTORMS WEDNESDAY INTO WEDNESDAY EVENING. WHILE IT IS EARLY...
THIS COULD BE THE TIME FOR AN INCREASING THREAT OF LOCALLY HEAVY
RAIN AS PRECIPITABLE WATER VALUES INCREASE TO NEAR 1.75 INCHES.
AFTER WEDNESDAY EVENING...FORECAST CONFIDENCE GOES DOWN. THIS IS NOT
BECAUSE OF MODEL DIFFERENCES...SINCE THE 1200 UTC GFS AND ECMWF ARE
NO THAT FAR APART WITH RESPECT TO MASS FIELDS. THE PROBLEM IS THE
POSITIONING OF THE WARM FRONT THAT BECOMES A QUASI STATIONARY FRONT
NEAR THE SOUTHERN PART OF THE FORECAST AREA. BECAUSE OF THE POSITION
OF THE FRONT...WILL TRY TO PAINT A PICTURE SHOWING A BETTER CHANCE
OF SHOWERS AND THUNDERSTORMS SOUTH AND A LESSER CHANCE TO THE NORTH.
AGAIN...THE FORECAST CONFIDENCE HERE IS BELOW NORMAL...SO A CHANCE
OF SHOWERS AND THUNDERSTORMS WAS INSERTED INTO THE FORECAST FOR
WEDNESDAY INTO FRIDAY. AT THIS DISTANCE...IT DOES NOT APPEAR THIS
PERIOD WILL BE A WASHOUT...BUT TIMING AND PLACEMENT PROBLEMS REQUIRE
USING A BROAD STROKE WHEN PAINTING THE SHOWER AND THUNDERSTORM
PICTURE. WILL TRY TO KEEP THE CHANCES BELOW 30 PERCENT FOR
FRIDAY...AS THE FRONT MAY BE JUST SOUTH OF THE AREA.
850 MB TEMPERATURES FOR THE WEDNESDAY THROUGH FRIDAY PERIOD (NEAR 16
CELSIUS) WOULD SUGGEST THAT 90 DEGREE HIGHS ARE NOT OUT OF THE
QUESTION FOR THIS PERIOD. BECAUSE OF UNCERTAINTY IN CLOUD COVER...
WILL KEEP TEMPERATURES JUST BELOW THIS LEVEL. HOWEVER...IF THE
FRONTAL BOUNDARY ENDS UP A BIT FURTHER NORTH...SOUTHERN AREAS MAY BE
ABLE TO BREAK AND HIGHS COULD REACH 90 DEGREES.
&&
.AVIATION /01Z SATURDAY THROUGH WEDNESDAY/...
FOR THE MOST PART...TERMINALS ARE VFR THIS EVENING. THERE ARE
STILL CONVECTIVE ELEMENTS ACROSS PORTIONS OF EAST CENTRAL
PENNSYLVANIA...AS THE AIRMASS REMAINS UNSTABLE WITH ENOUGH SHEAR
FOR SOME ORGANIZATION. RIGHT NOW...THE CONVECTION IS NORTH OF KABE
AND KRDG...SO THERE IS NOT PRECIPITATION IN THE TERMINALS NOW.
WILL CONTINUE TO INCLUDE A CB REMARK FOR THE NEXT THREE HOURS FOR
THE TERMINAL FORECASTS NORTH OF KPNE...AS THIS AREA STANDS THE
BEST CHANCE OF SEEING CONVECTION. SOUTH OF THIS...WITHOUT A FOCUS
FOR THUNDERSTORMS...THEY HAVE BEEN LEFT OUT.
JUST SOME BLOW OFF CIRRUS FOR THE REST OF THE TERMINALS. THE
GRADIENT HAS DROPPED OFF OVER LAND AS DECOUPLING IS STARTING TO
OCCUR. CONTINUED THE MENTION OF HAZE FOR A FEW OF THE TERMINALS...
AND MAY HAVE TO HI THE FOG HARDER AT KABE AS THEY DID SEE SOME
RAIN AND MAY SATURATE AFTER 0800 UTC.
A VERY HOT AND HUMID DAY IS FORECAST FOR SATURDAY, BUT WITH
BASICALLY VFR CONDITIONS. SOME SCATTERED TO WIDELY SCATTERED SHOWERS
AND THUNDERSTORMS ARE FORECAST, BUT THE CHANCES AND CONFIDENCE OF
ONE AT THIS FORECAST JUNCTURE AFFECTING ANY TERMINAL IS TOO LOW TO
CARRY OR MENTION A CB CLOUD GROUP. THE GENERAL WIND FLOW IS EXPECTED
TO BE MORE OUT OF THE WEST AND IN SPITE OF HIGHER TEMPERATURES, THE
SEA BREEZE FRONT SHOULD REMAIN EAST OF ALL OF THE TERMINALS.
OUTLOOK...
SOME MARGINAL VFR TO BRIEFLY IFR CONDITIONS ARE POSSIBLE AS
SCATTERED SHOWERS AND THUNDERSTORMS ASSOCIATED WITH THE COLD FRONT
MOVE THROUGH OUR AREA LATER SATURDAY INTO SUNDAY. GOOD VFR
CONDITIONS ARE EXPECTED SUNDAY NIGHT INTO TUESDAY. THE NEXT CHANCE
FOR MVFR OR BRIEFLY IFR CONDITIONS WILL BE WITH AN APPROACHING WARM
FRONT LATE TUESDAY NIGHT INTO WEDNESDAY.
&&
.MARINE...
WE KEPT FORECAST CONDITIONS BELOW SCA CRITERIA THROUGHOUT THIS
FORECAST PACKAGE ALTHOUGH WE SHOULD COME CLOSE WITH RESPECT TO SEAS
BOTH TONIGHT AND AGAIN SATURDAY NIGHT.
FOR TONIGHT...THE SOUTHWEST GRADIENT...WHICH CONTINUES OVER THE
WATERS...IS PRODUCING GUSTS NEAR 20 KNOTS AT THE BUOYS. IT APPEARS
AS THOUGH WINDS WILL REMAIN BELOW 25 KNOTS...AS THE BEST SURFACE
GRADIENT SHOULD BE OVER THE REGION DURING THE NEXT 2 TO 4 HOURS.
HOWEVER...SEAS MAY BE ANOTHER STORY. RIGHT NOW...SEAS ARE RUNNING
3 TO 4 FEET ACROSS THE WATERS WITH A SHORT 4 SECOND CHOP. FOR
NOW...WILL LEAVE THE FORECAST AS IS (NO SMALL CRAFT ADVISORY FOR
SEAS)...AS THE BEST FETCH REMAINS NORTH OF THE WATERS. WILL
CONTINUE TO MONITOR TO SEE IF NORTHERN WATERS CAN INDEED TOUCH 5
FEET WITH A SHORT PERIOD TONIGHT.
WAVE WATCH GUIDANCE CONTINUES TO BE TRIMMED BY ABOUT 1 FOOT UNTIL
THE COLD FRONTAL PASSAGE ON SUNDAY. SO FAR TODAY SEAS ARE VERIFYING
EITHER AT OR ABOUT A FOOT BELOW WAVE WATCH GUIDANCE. THE WRF-NMM
FORECAST SOUNDINGS ARE VERIFYING PRETTY WELL WITH RESPECT TO SURFACE
WINDS OFFSHORE. GIVEN THIS IS A VERY HOT AIR MASS PASSING OVER
RELATIVELY COOLER WATERS, WE ARE NOT EXPECTING THOROUGH MIXING TO
OCCUR. SCA WINDS ARE NOT FORECAST TO OCCUR TONIGHT AS THE STRONGER
WIND ALOFT PASSES OVER THE MARINE AREA. THE SAME CAN BE SAID FOR
SATURDAY NIGHT.
HOWEVER, LOWER CONFIDENCE EXISTS AS TO WHETHER SWELLS ASSOCIATED
WITH THE SOUTHERLY WIND FLOW WILL BANK FAR ENOUGH TO THE WEST TO
AFFECT OUR MARINE OCEANIC AREA. GIVEN THE GFS TENDENCY TO
OVERFORECAST SURFACE WINDS WHEN THE AIR TEMPERATURE IS GREATER THAN
THE WATER, WE LOWERED WAVE WATCH GUIDANCE SLIGHTLY INTO SATURDAY
NIGHT. WHILE WE WILL CARRY THE MENTION OF 5 FT SEAS FOR SATURDAY
NIGHT INTO EARLY SUNDAY, CONFIDENCE IS TOO LOW TO ISSUE A SMALL
CRAFT ADVISORY.
ON SUNDAY, THE STRONGER WESTERLY FLOW WILL OCCUR INTO THE EVENING,
BUT BEFORE AIR TEMPERATURES ARE FORECAST TO DROP BELOW THE WATER
TEMPS. AFTER THAT, A HIGH PRESSURE SYSTEM WILL BUILD EAST AND WINDS
WILL DECREASE INTO TUESDAY WHEN THE HIGH IS EXPECTED TO REACH OUR
AREA WATERS. EVEN AFTER IT SLIDES FARTHER OFFSHORE ON WEDNESDAY, THE
OVERALL PRESSURE GRADIENT IS FORECAST TO REMAIN FAIRLY WEAK AND WE
SHOULD REMAIN BELOW SMALL CRAFT ADVISORY CRITERIA.
