Damaging Wind in Delaware, September 2, 2013

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE MOUNT HOLLY NJ
708 PM EDT MON SEP 2 2013

.SYNOPSIS...
A COLD FRONT APPROACHING FROM THE NORTHWEST WILL MOVE THROUGH THE
AREA ON TUESDAY MORNING. A HIGH PRESSURE SYSTEM WILL BRIEFLY BUILD
OVER THE REGION ON WEDNESDAY. A RE-ENFORCING COLD FRONT SHOULD
MOVE ACROSS THE AREA ON THURSDAY FOLLOWED BY A CENTRAL CANADIAN
HIGH PRESSURE SYSTEM FOR THE END OF THE WEEK. ANOTHER COLD FRONT
IS EXPECTED TO PASS THROUGH THE NORTHEAST ON SUNDAY WITH ANOTHER
CANADIAN HIGH PRESSURE SYSTEM FOLLOWING ON MONDAY.

&&

.NEAR TERM /UNTIL 6 AM TUESDAY MORNING/...
SCATTERED SHOWERS AND THUNDERSTORMS EXTENDED FROM THE MIDDLE AND
LOWER PARTS OF THE SUSQUEHANNA RIVER VALLEY IN PENNSYLVANIA TO THE
LEHIGH VALLEY REGION AROUND 700 PM. THE CONVECTION WAS LOCATED IN
AN AREA OF INSTABILITY THAT WAS OUT AHEAD OF AN APPROACHING COLD
FRONT. THE SHOWERS AND THUNDERSTORMS ARE EXPECTED TO DISSIPATE
GRADUALLY WITH THE LOSS OF DAYTIME HEATING. WE HAVE LOWERED THE
CHANCES FOR PRECIPITATION IN MUCH OF OUR REGION FOR THIS EVENING
AND OVERNIGHT BASED ON THE TREND AND THE PRECIPITATION COVERAGE AT
700 PM.

THE COLD FRONT EXTENDED ACROSS WESTERN NEW YORK, WESTERN
PENNSYLVANIA AND DOWN THE OHIO RIVER VALLEY EARLY THIS EVENING. IT
WILL CONTINUE TO PROGRESS TO THE EAST AND IT SHOULD BEGIN TO MOVE
INTO OUR REGION TOWARD MORNING. THE CONVECTION ALONG THE FRONT
SHOULD ALSO WEAKEN THIS EVENING WITH PERHAPS SCATTERED SHOWERS
REACHING OUR FORECAST AREA LATE TONIGHT.

EVEN WITH THE COLD FRONT NEARING US, THE WIND IS EXPECTED TO
REMAIN RATHER LIGHT DURING THE NIGHTTIME HOURS. THERE WILL BE
ABUNDANT LOW LEVEL MOISTURE, ESPECIALLY AT THOSE LOCATIONS THAT
RECEIVED HEAVY RAINFALL TODAY. AS A RESULT, WE HAVE MENTIONED
PATCHY FOG FOR LATE TONIGHT. MINIMUM TEMPERATURES ARE FORECAST TO
BE MAINLY IN THE UPPER 60S AND LOWER 70S. READINGS IN THE LOWER
AND MIDDLE 60S ARE POSSIBLE IN OUR NORTHWESTERN COUNTIES WITH THE
ARRIVAL OF THE COLD FRONT.

&&

.SHORT TERM /6 AM TUESDAY MORNING THROUGH 6 PM TUESDAY/...
A MUCH BETTER DAY IS IN STORE ON TUESDAY AS HIGH PRESSURE BUILDS
IN FROM THE W. SOME GUID INDICATES THERE COULD BE SOME LINGERING
PRECIP IN THE MRNG (MAINLY DUE TO THE PROXIMITY OF THE FRONT), BUT
QPF WILL BE LIGHT. SO, FOR NOW WILL KEEP SLIGHT CHCS ERLY AND THEN
NO POPS FOR THE AFTN/EVE, BUT CERTAINLY NOTHING LIKE TODAY. WITH
MORE SUNSHINE, EXPECT TEMPS TO REBOUND INTO THE MID-UPPER 80S,
HOWEVER, IT WILL BE NOTICEABLY MORE COMFORTABLE WITH DEW POINTS
FALLING THRU THE 60S AND EVEN INTO THE 50S BY MID-LATE AFTN.

&&

.LONG TERM /TUESDAY NIGHT THROUGH MONDAY/...
THE GFS INITIALIZATION CONTINUES TO BE SHARPER THAN THE WRF-
NMMB. OVERALL THIS 12Z MODEL RUN WAS PRETTY CONSISTENT WITH RECENT
PREVIOUS RUNS AND THE MEDIUM RANGE MODELS WERE OVERALL FAIRLY
CLOSE. PLEASE REFER TO PMDHMD AS THE OP GFS RUN IS CLOSE TO THE
MODEL CONSENSUS MEAN AND WILL BE GIVEN HIGHER WEIGHT THAN AVERAGE.
THE HIGHEST IMPACTING WEATHER IS IN THE NEAR AND SHORT TERM WITH
GENERALLY DRY WEATHER WITH AROUND SEASONABLE TEMPERATURES
RETURNING. THERE WILL BE A PAIR OF COLD FRONTAL PASSAGES, BUT BOTH
LOOK TO HAVE A MINIMAL IMPACT AT THIS JUNCTURE.

TUESDAY NIGHT WILL CONTINUE THE FIRST LEG DOWNWARD OF
TEMPERATURES AND DEW POINTS IN THE LONG TERM. THE LONG WAVE TROF
IS YET TO CLEAR OUR CWA AT THE START OF THE EVENING, SO WE
CONTINUED THE IDEA WITH PVA INTO PART OF THE NIGHT OF KEEPING SOME
CLOUDINESS PRESENT IN THE HIGHER TERRAIN NORTH. THE OVERALL
GRADIENT IS FORECAST TO WEAKEN AS WE PROGRESS THROUGH THE NIGHT.
DONT KNOW IF THIS IS GOING TO BE THE CASE WITH THE DNVA 2ND HALF
OF THE NIGHT. THUS WE WILL OPT FOR SLIGHTLY MORE MIXING AND THUS
AN AVERAGE OF STAT GUIDANCE FOR MIN TEMPERATURES.

THE NEXT HIGH PRESSURE SYSTEM SHOULD BE CRESTING OUR AREA ON
WEDNESDAY. FORECAST MOISTURE IS EXTREMELY MEAGER AND THE FCST
CONVECTIVE TEMPERATURE IS IN THE 100S. PLENTY OF SUNSHINE
EXPECTED. STAT GUIDANCE LOOKS PRETTY GOOD GIVEN FCST 925 MB AND
850MB TEMPS AND ALSO EXPECTED WARMING ALOFT AS THE DAY CONTINUES.

THE NEXT COLD FRONT IS FORECAST TO APPROACH ON WEDNESDAY NIGHT.
THIS IS THE REVERSE WHERE MOST OF THE NIGHT SHOULD BE ON THE CLEAR
SKIES AND LIGHTER WINDS. STAT GUIDANCE LOOKS A BIT TOO HIGH
(BANKING ON THE CLOUDS) AND WE WENT BELOW IT.

WE DID KEEP THE THURSDAY FCST DRY WITH THE NEXT CFP. GREATER
CONFIDENCE NORTH THAN SOUTH BASED ON THE CURRENT TIMING OF THE
FRONT. SOUTH THE FORECAST MLCAPE (IF THERE IS ANY DEPENDING UPON
YOUR MODEL OF CHOICE) IS NOT IMPRESSING US AND HAS NOT REACHED THE
POINT WHERE WE ARE UNCOMFORTABLE LEAVING THE GRIDS/FCST DRY. TO
THAT END, THE FORECAST MOISTURE RECOVERY IS NOT ROBUST. THE FCST
JET IS DECENT AS IS THE FCST MID LEVEL QVEC CONVERGENCE, SO WE
WILL HAVE TO MONITOR THE MOISTURE RETURN IN THE DAYS AHEAD AS WE
HAVE MORE CONFIDENCE ON THE FORMER THAN THE LATTER. WE LIKE THE
HIGHER STAT GUIDANCE FOR MAX TEMPS GIVEN THE SLIGHTLY SLOWER
TIMING OF THE CFP.

THEN ANOTHER REINFORCING SHOT OF CANADIAN AIR FOR THE END OF THE
WEEK IS EXPECTED. FRIDAY WILL LIKELY BE RELATIVE TO NORMAL THE
COOLEST DAY OF THE LONG TERM. THERE MAY BE TOO MUCH OF A GRADIENT
ON THU NGT TO TOTALLY DECOUPLE, MORE LIKELY TO OCCUR ON FRIDAY
NIGHT IN WHICH MINS ARE FCST TO BE 5-15F LOWER THAN URBAN AREAS
AND LOCALES RIGHT ALONG THE IMMEDIATE SHORE.

SATURDAY WE SHOULD START MODERATING PRECEDING THE NEXT CFP. THE
SUNDAY CFP DOES NOT LOOK THAT FOREBODING EITHER. POPS WERE BASED
ON AN HPC/CONTINUITY BLEND. ITS A LONG WAY OUT, BUT CURRENTLY DO
NOT SUPPORT THUNDER. WE STAYED CLOSER TO THE HIGH END OF STAT
GUIDANCE BASED ON EXPECTED MAXS ON FRIDAY AND SATURDAY, SHOULD NOT
BE LOWER. THEN A RETURN OF SLIGHTLY COOLER TEMPERATURES ON MONDAY.
THE UPSHOT FOR THE LONG TERM, NO DEW POINTS AS HUMID AS THEY HAVE
BEEN THE PAST COUPLE OF DAYS.

&&

.AVIATION /00Z TUESDAY THROUGH SATURDAY/...
THE FOLLOWING DISCUSSION IS FOR KPHL, KPNE, KTTN, KABE, KRDG,
KILG, KMIV, KACY AND SURROUNDING AREAS.

CONDITIONS WERE VFR AT ALL EIGHT OF OUR TAF SITES AT 2300Z. THE
SHOWERS AND THUNDERSTORMS THAT WERE AROUND KABE AND KRDG AND IN
AREAS TO THE WEST SHOULD CONTINUE TO WEAKEN AND DISSIPATE WITH THE
LOSS OF DAYTIME HEATING.

ABUNDANT LOW LEVEL MOISTURE IN OUR REGION MAY RESULT IN THE
DEVELOPMENT OF AREAS OF LOW CLOUDS AND FOG DURING THE NIGHT.

A COLD FRONT FROM THE NORTHWEST IS FORECAST TO ARRIVE ON TUESDAY
MORNING. IT WILL BRING DRY AIR AND VFR CONDITIONS TO OUR REGION
FOR MUCH OF TUESDAY.

A LIGHT WIND OVERNIGHT IS EXPECTED TO BECOME NORTHWEST FOR TUESDAY
AND IT SHOULD INCREASE AROUND 8 TO 12 KNOTS.

OUTLOOK...
TUESDAY NIGHT THROUGH SATURDAY...VFR CONDITIONS EXPECTED.
POSSIBLY SOME FOG RELATED RESTRICTIONS ON FRIDAY AND SATURDAY
MORNINGS IN RURAL AIRPORTS.

&&

.MARINE...
RELATIVELY QUIET CONDS ON THE AREA WATERS WITH A SWLY FLOW GENLY
10 KTS OR LESS WITH GUSTS 10 TO 15 KT RANGE. THE WIND WILL BECOME
W THEN NW AT THE SAME SPEED BY TUE AFTN AS A CDFNT WORKS ITS WAY
THRU THE CSTL WATERS. SEAS WILL GENLY BE AROUND 3 FT. NO HEADLINES
ARE ANTICIPATED THRU THE NR AND SHORT TERM PDS.

OUTLOOK...
NO SCA CONDITIONS ARE EXPECTED FOR THE REMAINDER OF THIS WEEK.
WINDS WILL BE GENERALLY NORTHWEST AND SOMEWHAT STRONGER BEHIND
COLD FRONTS ON TUESDAY NIGHT AND AGAIN ON THURSDAY NIGHT, BUT NOT
EXPECTED TO REACH SCA CRITERIA. EVEN LIGHTER WINDS AND LOWER SEAS
EXPECTED AS HIGH PRESSURE SYSTEMS BUILD OVER THE AREA WATERS ON
WEDNESDAY AND SATURDAY.
