What forecasters said that day

The local office's own words before this areal flood warning 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 areal flood warning went out at Aug 15, 5:09 AM EDT, 22 minutes earlier.

Area forecast discussion, Aug 15, 5:09 AM EDT, 22 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE MOUNT HOLLY NJ
509 AM EDT MON AUG 15 2011

.SYNOPSIS...
LOW PRESSURE NEAR JUST EAST OF DELAWARE WILL PASS CLOSE TO CAPE
COD LATE TONIGHT OR TUESDAY MORNING. HIGH PRESSURE FOLLOWING FROM
THE OHIO VALLEY WEDNESDAY WILL BECOME ABSORBED INTO LARGER HIGH
PRESSURE ANCHORED OVER THE WEST CENTRAL ATLANTIC. THIS SHOULD
RESULT IN A PERSISTENTLY MOIST SOUTHERLY FLOW AT THE END OF THE
COMING WORK WEEK.

&&

.NEAR TERM /UNTIL 6 PM THIS EVENING/...
CANCELLED REMAINDER OF FFA DUE TO LACK OF ORGANIZED HEAVY CONVECTION
AT 5 AM AND NONE EXPECTED PRIOR TO THIS AFTN.

AM EXPECTING RENEWED HEAVY CONVECTION THIS AFTN BUT PROBABLY IN
SMALLER CLUSTERS WITH SMALLER YIELDS DUE TO LOWER PWAT OF AROUND
1.5 INCHES.

HOWEVER...IF THESE PASS OVER REGION THAT EXPERIENCED 3+ INCH RAINS
THIS WEEKEND...THEN NEW ADVISORIES OR SHORT FUSE FLASH FLOOD WARNINGS
WOULD BE NEEDED. CAN SEE THIS OCCURRING BUT DIDNT WANT TO KEEP A
FFA GOING FOR A PROBABLE SMALL FRACTION OF COVERAGE OF NEW AFTERNOON
POOR DRAINAGE FLOODING RAINS THAT WILL SLOW TRAFFIC.

THE TT ARE LARGE AND BULK SHEAR IS MINIMAL...THE IDEA BEING THAT
HAIL MAY OCCUR IN SEVERAL STORMS THIS AFTN WITH MAX GUST EXPECTED
UNDER 40 KTS.

BLENDED 00Z/15 GUIDANCE TEMPS-WINDS LOOKED REASONABLE.

&&

.SHORT TERM /6 PM THIS EVENING THROUGH WEDNESDAY NIGHT/...
THIS EVENING...LEFTOVER HEAVY SHOWERS AND ISOLATED TSTMS SHOULD
DIMINISH DURING THE NIGHT.

TUESDAY...A RENEWAL OF SHOWERS EXPECTED...ESPECIALLY NJ WITH A
SMALLER CHC OF OF TSTMS DUE TO A SOMEWHAT MORE STABLE ENVIRONMENT
AND SWD ROTATING BAND OF HIGH RH AS THE TROF ALOFT N-S AXIS EDGES E
OF THE NJ COAST.

TUES NIGHT...SHOWERS SHOULD GRADUALLY END FOLLOWED BY CLEARING.
PATCHY FOG POSSIBLE LATE.

WEDNESDAY...LOOKS LIKE A GOOD DAY WITH WARMER TEMPS DURING THE
DAY WITH HIGH PRES THE PRIMARY INFLUENCE. PATCHY FOG POSSIBLE
LATE THAT NIGHT.

&&

.LONG TERM /THURSDAY THROUGH SUNDAY/...
THIS PORTION OF THE DISCUSSION WAS GENERATED 3 PM SUNDAY
AFTERNOON.

THIS TIME FRAME STILL HAS SOME UNCERTAINTY WITH IT DUE TO SOME
VARIATIONS IN THE MODEL GUIDANCE WITH THE OVERALL SYNOPTIC FLOW.
THIS IS PARTICULARLY TRUE ACROSS WESTERN AND SOUTHERN CANADA AND
ALSO ALONG THE NORTHERN TIER OF THE U.S. THIS THEN HAS SOME
DOWNSTREAM AFFECTS WITH TIME. HPC GUIDANCE WAS FOLLOWED.

BASED ON THE ABOVE, HIGH PRESSURE SETTLES OVER THE AREA WEDNESDAY
NIGHT BEFORE SHIFTING TO OUR EAST THURSDAY. AS THE SURFACE HIGH
SLIDES TO OUR EAST, THE RETURN FLOW WILL ALLOW MOISTURE TO INCREASE
THURSDAY AND FRIDAY AND A COLD FRONT TO APPROACH FROM THE WEST. WE
ALSO MAY HAVE LEE SIDE TROUGH DEVELOPMENT DURING FRIDAY. THE FRONT
MAY EITHER STALL JUST TO OUR WEST OR TEND TO REORGANIZE TO OUR
SOUTHEAST AS UPPER-LEVEL ENERGY MAY TRY TO SHARPEN UP A BIT
SATURDAY. THIS CARRIES LOWER CONFIDENCE ESPECIALLY WITH THE TIMING
OF ADDITIONAL ENERGY SLIDING ACROSS THE NORTHERN TIER OF STATES
FRIDAY THROUGH SUNDAY. THEREFORE, WILL GO WITH SLIGHT CHC TO LOW CHC
POPS THURSDAY THROUGH SUNDAY. AS FOR TEMPERATURES, WE FOLLOWED HPC
GUIDANCE RATHER CLOSELY ATTM.

&&

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

HIGHLY VARYING CONDITIONS AT THE TAF SITES EARLY TODAY...THE TREND
TOWARD LOWER CIGS/VSBYS LOOK GOOD WITH ABUNDANT LOW LEVEL MOISTURE
AND OCNL SHOWERS ROTATING ACROSS THE REGION EARLY TODAY. THE LOW
RESPONSIBLE FOR THE POOR CONDITIONS WILL MOVE SLOWLY NE ACROSS THE
AREA TODAY. CONDITIONS WILL ONLY IMPROVE SLOWLY TODAY. WINDS WILL
MOSTLY BE LIGHT FROM THE E OR NE THIS MORNING AND THEN N OR NW THIS
AFTERNOON.

OUTLOOK...
GRADUAL IMPROVEMENT EXPECTED TUESDAY WITH MORE OPPORTUNITIES FOR VFR
CONDITIONS...BUT STILL SCATTERED SHOWERS WITH LOWER CONDITIONS AT
TIMES. MOSTLY VFR WED-THU.

&&

.MARINE...
MARGINAL SCA CONDITIONS (SEAS) ON THE OCEAN WATERS EARLY THIS
MORNING WILL LINGER INTO THE LATER MORNING HOURS AS LOW PRESSURE
CROSSES SOUTH OF THE AREA. WE WILL CONTINUE THE SCA FLAG FOR ALL
WATERS THRU 15Z FOR NOW AND RE-EVALUATE LATER. THE LOW WILL CONTINUE
NE AWAY FOR THE WATERS TONIGHT AND THEN HIGH PRESSURE WILL MOVE IN.
SUB-SCA CONDITIONS ARE EXPECTED FROM TONIGHT THRU THE NEXT SEVERAL
DAYS. SCAT SHOWERS/TSTMS MAY STILL PRODUCE LOCALIZED HIGHER WINDS
AND WAVES.

&&

.HYDROLOGY...
PLEASE SEE THE NEAR TERM SECTION FOR HYDRO UPDATES NOW THAT THE
FFA IS COMPLETELY DISCONTINUED.
