Area forecast discussion, May 19, 10:45 PM EDT, 38 minutes before
AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE MOUNT HOLLY NJ
1045 PM EDT THU MAY 19 2011
.SYNOPSIS...
PERSISTENT LOW PRESSURE OVER THE EASTERN PORTION OF THE NATION
WILL REMAIN OVER THE REGION THROUGH FRIDAY BEFORE FINALLY MOVING
OFFSHORE FRIDAY NIGHT. HIGH PRESSURE WILL BUILD DOWN FROM THE
CANADIAN MARITIMES SATURDAY INTO SUNDAY. A WARM FRONT COULD BRING
SOME RAIN LATER SUNDAY.
&&
.NEAR TERM /UNTIL 6 AM FRIDAY MORNING/...
THE MID LEVEL CLOSED SYSTEM LOOKS TO BE LOCATED OVER SOUTH CENTRAL
PENNSYLVANIA...BASED ON THE LATEST WATER VAPOR IMAGERY. THE LATEST
SPOKE ROTATING AROUND THE CLOSED LOW WAS ABOUT TO EXIT THE CENTRAL
NEW JERSEY COAST. THE AIRMASS IS STILL MARGINALLY UNSTABLE...BASED
MAINLY ON THE 0000 UTC SOUNDINGS AND LATEST MESOSCALE ANALYSIS.
THE REGIONAL RADAR LOOP CLEARLY SHOWS THE CYCLONIC FLOW AROUND THE
MID LEVEL SYSTEM...AND THE ACTIVITY ACROSS EASTERN MARYLAND AND
EAST CENTRAL PENNSYLVANIA WILL MAKE ITS WAY ACROSS THE FORECAST
AREA DURING THE NEXT COUPLE OF HOURS. AFTER THE LAST OF THE
INSTABILITY IS EXHAUSTED...SCATTERED SHOWERS SHOULD CONTINUE
THROUGH THE EARLY MORNING HOURS...MAINLY ACROSS NORTHER AREAS.
WHILE NOT EVIDENT YET...FOG COULD BECOME A PROBLEM LATER TONIGHT
AS THE LOW LEVEL FLOW REMAINS LIGHT...ALBEIT FROM A LAND
TRAJECTORY FOR MOST PLACES. FOR THE MOST PART...LOW TEMPERATURES
APPEAR TO BE ON TRACK.
&&
.SHORT TERM /6 AM FRIDAY MORNING THROUGH SUNDAY/...
ONE MORE DAY OF THIS BEFORE WE SEE SOME IMPROVEMENT. THE PESKY
UPR LOW WILL FINALLY BEGIN TO EXIT STAGE RIGHT ON FRIDAY, BUT NOT
BEFORE THE STAGE IS SET FOR ANOTHER DAY WITH SHOWERS AND GENLY
AFTN/EVENING TSTMS, EVEN THOUGH THE ODDS MAY BE A BIT LESS THAN
THE PREV FEW DAYS. THE TROF IS OFF THE CST BY SAT MORNING AND HGTS
RISE AS A RIDGE BUILDS IN. THIS SHOULD MAKE SATURDAY A DRY AND
WARM DAY. SOME PRECIP COULD ARRIVE FOR THE SECOND HALF OF SUNDAY
AS A WARM FRONT MOVES TWD THE AREA EXTENDING FROM LOW PRES OVER
THE NRN PLAINS. THERE ARE STILL SOME TIMING DIFFS WRT THIS FRONT
AND THE ONSET OF PRECIP. THE ECMWF KEEPS THINGS DRY THROUGH THE
DAY ON SUN WHILE THE GFS WOULD HAVE SOME POPS FOR THE SECOND HALF
OF THE DAY. FOR NOW WILL JUST GO WITH SOME SCHC POPS AND WAIT TO
SEE WHAT LATER MDL RUNS DO.
AGAIN, GUID TEMPS LOOKED GOOD OVERALL, WITH A FEW TWEAKS HERE AND
THERE.
&&
.LONG TERM /SUNDAY NIGHT THROUGH THURSDAY/...
ON SUNDAY NIGHT, A MID AND UPPER LEVEL RIDGE IS FORECAST TO
EXTEND OVER THE COASTAL WATERS. THE FEATURE SHOULD DRIFT OUT OVER
THE WESTERN NORTH ATLANTIC DURING THE EARLY PART OF THE NEW WEEK.
A MID LEVEL TROUGH IS EXPECTED TO BECOME ESTABLISHED OVER THE
MIDDLE PART OF THE COUNTRY DURING THE MID WEEK PERIOD.
AT THE SURFACE, A WARM FRONT MAY LIFT THROUGH OUR REGION ON
SUNDAY NIGHT. AS A RESULT, WE HAVE INCLUDED LOW CHANCE OR SLIGHT
CHANCE POPS AT THAT TIME. HIGH PRESSURE IS EXPECTED FOR MONDAY,
WITH DRY WEATHER CONDITIONS ANTICIPATED. A FRONTAL BOUNDARY FROM
THE NORTHWEST IS FORECAST TO APPROACH ON TUESDAY BEFORE SETTLING
INTO OUR REGION FOR WEDNESDAY AND THURSDAY. WE WILL CARRY LOW
CHANCE OR SLIGHT CHANCE POPS FOR TUESDAY AND WEDNESDAY, MAINLY
ACROSS OUR NORTHERN COUNTIES. WE WILL EXPAND THE CHANCE POPS
SOUTHWARD FOR THURSDAY IN ASSOCIATION WITH THE FRONT.
WITH THE GENERAL SOUTH TO SOUTHWEST FLOW, ABOVE NORMAL
TEMPERATURES ARE EXPECTED FROM MONDAY THROUGH THURSDAY ALONG WITH
AN INCREASE IN HUMIDITY.
&&
.AVIATION /03Z FRIDAY THROUGH TUESDAY/...
THE FOLLOWING DISCUSSION IS FOR KPHL, KPNE, KTTN, KABE, KRDG,
KILG, KMIV, KACY AND SURROUNDING AREAS.
SCATTERED SHOWERS AND ISOLATED THUNDERSTORMS WILL CONTINUE TO
AFFECT OUR REGION TONIGHT, AS LOW PRESSURE AT THE SURFACE AND
ALOFT PASSES OVER OUR REGION. UNTIL ABOUT 0600Z, IT APPEARS AS
THOUGH CONDITIONS WILL BE VFR OUTSIDE OF ANY PRECIPITATION.
WITH A FAIR AMOUNT OF LOW LEVEL MOISTURE, VISIBILITY VALUES MAY
DROP INTO THE MVFR RANGE FOR LATE TONIGHT AND EARLY FRIDAY
MORNING.
MAINLY VFR CONDITIONS ARE ANTICIPATED FOR FRIDAY. HOWEVER,
ADDITIONAL SCATTERED SHOWERS AND THUNDERSTORMS WILL AFFECT OUR
REGION AND THEY MAY REDUCE CEILING AND VISIBILITY VALUES AT TIMES.
THE WIND SHOULD BEGIN TO FAVOR A WESTERLY DIRECTION, ESPECIALLY
ON FRIDAY, WITH SPEEDS GENERALLY LESS THAN 10 KNOTS.
OUTLOOK...
A RELATIVELY TRANQUIL PERIOD IS FORECAST FROM FRIDAY NIGHT
THROUGH TUESDAY. HIGH PRESSURE IS EXPECTED OVER THE WEEKEND. A
WARM FRONT MAY LIFT THROUGH OUR REGION ON SUNDAY NIGHT INTO EARLY
MONDAY AND IT COULD BRING SOME LIGHT RAIN ALONG WITH REDUCED
CEILING AND VISIBILITY VALUES. HIGH PRESSURE SHOULD REGAIN ITS
INFLUENCE OVER OUR REGION FOR MONDAY AFTERNOON INTO TUESDAY.
&&
.MARINE...
SCA FOR SEAS WITH SWELL DECAY NEAR 5 FT SLIPPING BELOW 5 FT FROM
S TO N DURING THE NIGHT. TIMING BELOW 5 FT AT 44009 NEAR 02Z.
TIMING ELSEWHERE BETWEEN 06Z AND 10Z FRIDAY.
NO MARINE HEADLINES ANTICIPATED FRIDAY OTRW THAN A POSSIBLY MWS
IN THE AFTN FOR AN ISOLATED TSTM. THOSE SHOWERS AND SCT TSTORMS
STRUGGLING TO REACH THE COAST TODAY SHOULD HAVE A BETTER CHANCE
TOMORROW.
NO HEADLINES EXPECTED THIS WEEKEND THRU MONDAY POSSIBLY TUESDAY.
&&
.HYDROLOGY...
RIVER FLOOD WARNINGS CONTINUE FOR THE PASSAIC BASIN.
ADDITIONALLY, SOME URBAN AND SMALL STREAM FLOODING AND EVEN SOME
FLASH FLOODING IS POSSIBLE WITH SLOW MOVING THUNDERSTORMS THROUGH
THE EVENING HOURS. HOWEVER, THE THREAT DOES NOT APPEAR TO BE
WIDESPREAD ENOUGH TO WARRANT A FLASH FLOOD WATCH.
&&
.TIDES/COASTAL FLOODING...
CFS WBIS FOR A MARGINAL POSSIBLE EXCEEDENCE OF TIDAL FS TONIGHT.
WITH THE SFC FLOW TURNING SOUTHERLY...THIS SHOULD RELEASE A BIT OF
THE BUILDUP OF SURGE ALONG THE COAST. IN-HOUSE TOOLS ARE FCSTG
SURGE DIMINISHING TO HALF THE MID THURSDAY AFTN VALUES FOR
TONIGHTS HIGH TIDE CYCLE.
THEREFORE...HALF OF THE PRIMARY TIDAL MONITORING SITES MAY EXCEED
THE MINOR TIDAL FS BY AROUND 0.1 FT TONIGHT AND THE OTHER HALF
NOT. CONFIDENCE IS BELOW AVG TO BE ASSURED OF EXCEEDENCE OVER A
WIDE AREA TONIGHT...THEREFORE CFS. THIS MIGHT BE UPGRADED LATER
BUT FOR NOW...MY CONFIDENCE ON WIDESPREAD COVERAGE OF AN EXTENSIVE
MINOR EVENT /EXCEEDENCE BY UP TO 0.2 FT/ FOR TONIGHT IS LESS THAN
80 PERCENT.
