Special Weather Statement, NWS Philadelphia/Mount Holly

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE MOUNT HOLLY NJ
852 PM EDT TUE JUL 13 2010

.SYNOPSIS...
WEAK LOW PRESSURE OVER OUR REGION WILL SHIFT OFF THE COAST MIDDAY
WEDNESDAY BUT WILL SERVE TO FOCUS RENEWED HEAVY RAINFALL FROM
THUNDERSTORMS LATE TONIGHT AND WEDNESDAY MORNING IN PORTIONS OF
OUR AREA. HIGH PRESSURE FROM THE WEST SHOULD INFLUENCE OUR REGION
FROM WEDNESDAY INTO FRIDAY. A FRONTAL BOUNDARY IS FORECAST TO
APPROACH FROM THE NORTHWEST LATE ON FRIDAY AND IT MAY STALL OVER
OUR REGION DURING THE WEEKEND. THE BOUNDARY IS EXPECTED TO LIFT TO
THE NORTH ON MONDAY, WITH ANOTHER FRONT APPROACHING FROM THE
NORTHWEST ON TUESDAY.

&&

.NEAR TERM /UNTIL 8 AM WEDNESDAY MORNING/...
FLOOD WATCH EXPANDED SLIGHTLY NE AT 845 PM PER LATE AFTN HEAVY
DOUSING AS SEEN ON DIX STP.

SURFACE BOUNDARY REFORMING IN OUR CWA DURING THE NIGHT...POSSIBLY
FROM VICINITY OF NEWARK NJ TO HARRISBURG PA THEN GRADUALLY SHIFT
SE AS WEAK LOW PRES ORGANIZES ACROSS CENTRAL OR SOUTHERN NEW
JERSEY. 730 PM ANALYSIS SUGGESTS CONVERGENCE ZONE SETTING UP AS
INDICATED VCNTY EWR-ABE CXY. OVER SB CAPE 1000J ALONG AND S OF
THE THE BOUNDARY WITH PLENTY OF INSTAB.

TWO STATIONS IN N VA AT 7PM EDT WITH HRLY AMOUNTS NEAR 1 INCH.

THE FAIRLY DEEP ORGANIZED CYCLONIC CIRCULATION SYSTEM DEVELOPING
OVERNIGHT SHOULD FIND ITS HEAVIEST RAIN PRODUCING THUNDERSTORMS
AND SLOWEST MOVING SOMEWHERE ALONG THAT FRONTAL BOUNDARY. SHOWERS
OVER AND S OF PHL SHOULD BE FASTER MOVING TO THE NE OR ENE BUT
TRAINING MAY OCCUR THERE AS WELL DURING THE DAYBREAK HOURS WED AND
RESULT IN RENEWED FLOODING.

NAM HAS HAD TWO SUCCESSIVE RUNS OF 6.9 TO 8.1 INCHES OF RAIN IN
FAR SE PA OVERNIGHT...SMALL REGION. WONT BE SURPRISED AT NEW RFALL
BETWEEN 03Z AND 15Z WED OF ISO NEAR 6 OR 7 INCHES BUT WHERE?

FLASH FLOOD WATCH FOR THE URBAN CORRIDOR FROM EXTREME NORTHEASTERN
MARYLAND UP TO THE TRENTON AREA. MUCH OF THAT STRETCH RECEIVED ONE
OR TWO INCHES OF RAIN THIS MORNING, WITH LOCALLY HIGHER AMOUNTS
NEAR 3.5 INCHES. A SIMILAR SCENARIO IS ANTICIPATED FOR TONIGHT,
WHICH WOULD RESULT IN SOME FLASH FLOODING.

THE 18Z/13 GFS IS NOT MY FAVORITE CHOICE AMONG THE 12Z EC/12ZUK AND
18Z NAM BUT EVEN THAT HAS DECENT FGEN PHL NEWD TOMORROW MORNING
12Z. SO THERE IS UNCERTAINTY ON PLACEMENT BUT SOMETHING QUITE
LARGE 4+ QPF SHOULD OCCUR EARLY WED IN OUR CWA.

PWAT PREDICTED TO BE NEAR 2.3 INCHES DCA TO PHL BEFORE DAWN.

TO THE SOUTH OF THE PHILADELPHIA METROPOLITAN AREA, CONDITIONS
HAVE BEEN A BIT DRIER THAN THOSE TO THE NORTH OVER THE PAST FEW
DAYS. WITH THE SANDY SOIL, THOSE LOCATIONS CAN HANDLE A BIT MORE
RAIN. ALSO DOWN THERE...DEL NE MD AND FAR SNJ...STRONGER
UNIDIRECTION SHEAR MAY PLAY A ROLE IN STG SW GUST 40 KTS TWD
DAWN.

IT WILL REMAIN VERY WARM AND HUMID OVERNIGHT.

THERE MAY BE AN INTERNET PRODUCT POSTING PROBLEM ON THE FRONT PAGE
OF KPHI THAT WE CANNOT IMMEDIATELY RESOLVE.

&&

.SHORT TERM /8 AM WEDNESDAY MORNING THROUGH FRIDAY/...
THE MAIN AREA OF HEAVY RAIN SHOULD PASS OFF THE COAST EARLY ON
WEDNESDAY MORNING. HOWEVER, THE MID LEVEL SHORT WAVE WILL LAG
BEHIND IT. AS A RESULT, WE MAY SEE SCATTERED SHOWERS AND
THUNDERSTORMS ON WEDNESDAY. NEVERTHELESS, WE ARE EXPECTING SOME
SUNSHINE, ESPECIALLY DURING THE AFTERNOON. WE HAVE FAVORED THE
HIGHER MAV MAXIMUM TEMPERATURE NUMBERS OVER THOSE OF THE MET.

AN UPPER LEVEL RIDGE SHOULD POKE UP FROM THE SOUTHWEST FOR
THURSDAY INTO FRIDAY. IT WILL BRING VERY WARM CONDITIONS ALONG
WITH A CONTINUATION OF THE HIGH HUMIDITY. WE ARE COMING UP WITH
HEAT INDEX VALUES NEAR OR ABOVE 100 FOR THE PHILADELPHIA
METROPOLITAN AREA FOR THURSDAY AFTERNOON AND FRIDAY AFTERNOON. AS
A RESULT, AN EXCESSIVE HEAT WATCH HAS BEEN ISSUED FOR OUR HIGHLY
URBANIZED AREAS FROM NOON THURSDAY UNTIL FRIDAY EVENING.

A FRONTAL BOUNDARY MAY BEGIN TO APPROACH FROM THE NORTHWEST LATE
ON FRIDAY. WE HAVE MENTIONED CHANCE POPS FOR OUR NORTHWESTERN
COUNTIES AT THAT TIME.

&&

.LONG TERM /FRIDAY NIGHT THROUGH TUESDAY/...
HEAT ADVISORY PRODUCTS MAY STILL BE NECESSARY SATURDAY AND MAYBE
AGAIN MONDAY WHERE THRESHOLDS ARE 100 OR HIGHER. CONVECTIVE DEBRIS
CLOUDINESS MAY BE A LIMITING FACTOR ON WHETHER 100 CAN BE ATTAINED
ON SATURDAY.

NO CHANGE IN THE OVERALL PATTERN OF ABOVE NORMAL TEMPERATURES IN
THIS EXTENDED PORTION OF THE LONG TERM FORECAST OR BEYOND PER THE
12Z/13 NAEFS.

THIS MONTH IS ALREADY AVERAGING 4 DEGREES ABOVE NORMAL IN PHILADELPHIA
FOR THE FIRST 12 DAYS. PLEASE SEE CLIMATE SECTION.

THIS LONG TERM PERIOD SHOULD BE PART OF ANOTHER 4 TO 6 EXTENDED HEAT
WAVE IN PORTIONS OF OUR KPHI FORECAST AREA THAT MAY END AROUND
TUESDAY.

HPC GUIDANCE IS THE BASIS OF THIS FCST FRIDAY NIGHT THROUGH
TUESDAY WITH MINIMAL ADJUSTMENT IN THE GUIDANCE. 12Z GEFS POPS
AND MEAN QPF WERE REVIEWED AS WELL 12Z LOW RES GRAPHICS.

SUNDAY...MODEL SIGNALS CONTINUE TO DRY OUT SFC TD'S BUT STILL
HOT...BUT THE EC HAS DEWPOINTS COMING BACK UP SUBSTANTIALLY AT
LEAST ON MONDAY!

CONFIDENCE ON THE HEAT WAVE AND AT LEAST 1 DAY OF MARGINAL HEAT
ADVISORY CRITERIA PHL TO CENTRAL NJ IS ABOVE AVERAGE.

CONFIDENCE ON CONVECTION OCCURRING SATURDAY IS BELOW AVG.

12Z ECMWF HAS CONSIDERABLE SIGNAL FOR STRONG STORMS NEXT MONDAY
BUT THATS DAY6 AND MUCH CAN CHANGE /SHEAR KI TT SBLI/.

&&

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

TONIGHT THROUGH 14Z WED...VFR CIGS WILL BECOME IFR CONDS IN SHOWERS
AND HEAVY THUNDERSTORMS OVERNIGHT OR EARLY WED MORNING.

WE ARE AWARE OF TTN OBSERVED WX PROBLEM.

THE 12Z/13 NAM MOS WAS THE USUALLY MORE PESSIMISTIC PARTNER TO THE
GFS MOS WITH RESPECT TO CEILINGS OVERNIGHT.

WITH FRONTAL PASSAGE TOWARD MORNING...CONDITIONS ARE FORECAST TO
GRADUALLY IMPROVE DURING WEDNESDAY MORNING...BECOMING VFR BY MID
TO LATE MORNING.

OUTLOOK...
SCATTERED SHOWERS AND THUNDERSTORMS WILL REMAIN OVER THE REGION
THROUGH THE REMAINDER OF THE WEEK UNDER A HOT AND HUMID AIRMASS.
CONDITIONS SHOULD REMAIN VFR FROM WEDNESDAY AFTERNOON
ONWARD...WITH WINDS MAINLY FROM A SOUTHWESTERLY DIRECTION.
EXCEPTIONS WOULD BE VISIBILITY RESTRICTIONS IN PATCHY LATE NIGHT
AND EARLY MORNING FOG.

&&

.MARINE...
MARINE CONDITIONS ARE EXPECTED TO REMAIN JUST BELOW SMALL CRAFT
ADVISORY CRITERIA TONIGHT...AS A COLD FRONT APPROACHES FROM THE
WEST AND PASSES THROUGH THE AREA WEDNESDAY MORNING. SCATTERED
SHOWERS AND THUNDERSTORMS THIS AFTERNOON AND THIS EVENING WILL
BECOME WIDESPREAD LATER TONIGHT...AND WINDS AND WAVES WILL BE
HIGHER AROUND THUNDERSTORMS. WAVEWATCH GUIDANCE APPEARS TO BE
ABOUT ONE FOOT HIGHER THAN FORECAST CONDITIONS JUST AHEAD OF THE
COLD FRONT OVERNIGHT.

HIGH PRESSURE WILL BUILD IN WEDNESDAY NIGHT AND REMAIN THROUGH
FRIDAY...BUT ANOTHER REASONABLY STRONG COLD FRONT WILL CROSS THE
AREA WATERS SATURDAY WITH ADDITIONAL CONVECTION EXPECTED.

&&

.HYDROLOGY...
ANOTHER SLUG OF HEAVY RAIN IS FORECAST LATE TONIGHT AND WED
MORNING. A FLASH FLOOD WATCH HAS BEEN ISSUED FOR OUR URBAN
CORRIDOR FROM CECIL COUNTY IN MARYLAND UP TO THE TRENTON AREA.

WE ADDED A PTN OF CENTRAL NJ PER CURRENT TRAINING AND ANTICIPATED
REINFORCING SURGE SLY INFLOW WED MORNING AND THE PREV LATE TUE
AFTN DOUSING.

&&

.TIDES/COASTAL FLOODING...
A COASTAL FLOOD ADVISORY FOR MINOR TIDAL FLOODING WILL BE ISSUED
FOR THE NEW JERSEY OCEAN FRONT FOR THIS EVENING UNTIL ABOUT
MIDNIGHT... AS TIDAL ANOMALIES ARE ABOUT PLUS ONE-HALF FOOT THIS
AFTERNOON. MINOR FLOOD LEVELS MAY BE REACHED...ALTHOUGH AS WE
SEPARATE FROM THE NEW MOON OF SUNDAY...ASTRONOMICAL TIDES WILL BE
A TENTH OF A FOOT LESS THIS EVENING AS COMPARED WITH TUESDAY
EVENING. TIMING ISSUES AND PRESENT ANOMALIES INDICATED THAT THE
DELAWARE OCEAN FRONT...THE LOWER DELAWARE RIVER...AS WELL AS
DELAWARE BAY AND CHESAPEAKE BAY... WOULD NOT BE AFFECTED. HOWEVER
THE EVENING SHIFT IS URGED TO MONITOR THE DELAWARE SHORE...THE
LOWER DELAWARE RIVER...AND THE BAYS REGARDLESS.

&&

.CLIMATE...
THROUGH THE FIRST TWELVE DAYS OF JULY PHILADELPHIA HAS SEEN AN
AVERAGE TEMPERATURE OF 81.2 DEGREES. THE WARMEST JULY ON RECORD IN
TERMS OF AVERAGE TEMPERATURE OCCURRED IN 1994 WITH AN AVERAGE
TEMPERATURE OF 82.1 DEGREES. WE ARE NOT NECESSARILY SAYING THAT
WE'RE HEADING FOR THE TOP 5 WARMEST JULY'S ON RECORD...BUT IT
SHOULD BE NOTED THAT THE EXCESSES OF THE PAST FEW MONTHS ARE
DOCUMENTED INTO EARLY JULY AND WE'RE CERTAINLY GOING TO HEAT UP
AGAIN THIS WEEKEND INTO THE BEGINNING OF NEXT WEEK.

THERE MAY BE A BRIEF RETREAT TO NEAR NORMAL TEMPERATURES MIDDLE OF
NEXT WEEK BUT ITS NOT SOMETHING THAT I AM COUNTING ON SINCE NAEFS
IS RATHER WARM AND RECENT MONTHLY TRENDS HAVE BEEN WARM.

EIGHT OF THE FIRST 12 DAYS OF JULY IN PHILADELPHIA HAVE HAD HIGH
TEMPERATURES AT OR ABOVE 90 DEGREES. THE AVERAGE NUMBER OF 90
DEGREE DAYS IN JULY HERE IS 8.3 AND WE'RE BASICALLY THERE!

THE RECORD NUMBER OF DAYS WITH MAXIMUM TEMPERATURES EQUAL TO OR
EXCEEDING 90 DEGREES IS 21...THIS OCCURRED IN THREE DIFFERENT
YEARS: 1952, 1988, 1995.
