Special Weather Statement, NWS Philadelphia/Mount Holly

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE MOUNT HOLLY NJ
349 PM EDT THU MAY 24 2012

.SYNOPSIS...
HIGH PRESSURE TO OUR EAST WILL CONTINUE TO SLIDE FARTHER AWAY AND
WEAKEN THROUGH FRIDAY. AN AREA OF LOW PRESSURE TRACKING WELL TO OUR
NORTH THIS WEEKEND WILL PUSH A COLD FRONT TOWARD OUR AREA. THIS
FRONT SHOULD TEND TO STALL JUST TO OUR NORTH SUNDAY INTO MONDAY
BEFORE LIFTING NORTHWARD. MEANWHILE, AN AREA OF LOW PRESSURE
IS FORECAST TO DEVELOP TO OUR SOUTH TONIGHT AND LINGER THROUGH THE
WEEKEND AS IT GENERALLY MOVES SOUTHWESTWARD. A COLD FRONT IS
SCHEDULED TO ARRIVE LATE TUESDAY INTO WEDNESDAY, THEN HIGH PRESSURE
IN THE MIDWEST WILL START TO BUILD TOWARD THE NORTHEAST THURSDAY.

&&

.NEAR TERM /UNTIL 6 AM FRIDAY MORNING/...
THE SHOWERS AND THUNDERSTORMS THE REGION IS EXPERIENCING THIS
AFTERNOON WILL BECOME MORE ISOLATED TONIGHT. SLIGHTLY HIGHER POPS
EXIST IN THE UPSLOPE AREAS THIS EVENING. FOG AND LOW CLOUDS WILL
RETURN TONIGHT WITH THE MOISTURE, THE SOUTHERLY FLOW, AND THE
INVERSION. TEMPERATURES WILL FALL INTO THE UPPER 50S ACROSS THE
POCONOS AND THE INTO THE 60S ELSEWHERE. IT WILL FEEL MUGGY.

&&

.SHORT TERM /6 AM FRIDAY MORNING THROUGH 6 PM FRIDAY/...
TOMORROW CONTINUES TO LOOK SIMILAR TO TODAY...MORNING LOW CLOUDS AND
FOG...PARTIAL CLEARING...THEN ISOLATED TO SCATTERED SHOWERS AND
THUNDERSTORMS. WINDS WILL BE LITTLE MORE SOUTHERLY AHEAD OF AN
APPROACHING COLD FRONT. TEMPERATURES WILL BE IN THE MID TO UPPER 70S
NORTH AND WEST AND IN THE LOW TO MID 80S ELSEWHERE.

&&

.LONG TERM /FRIDAY NIGHT THROUGH THURSDAY/...
THIS TIME FRAME LOOKS TO FEATURE A STRETCH OF HOT AND HUMID
CONDITIONS ACROSS AT LEAST PORTIONS OF THE CWA ALONG WITH SOME
CONVECTIVE POTENTIAL. THE OVERALL SYNOPTIC PATTERN INVOLVES A
BUILDING RIDGE ACROSS THE MISSISSIPPI AND OHIO VALLEYS WHICH BECOMES
EXTENDED INTO THE MID ATLANTIC FOR A TIME. IT APPEARS THAT A POCKET
OF ENERGY ON THE EAST SIDE OF THIS BUILDING RIDGE RESULTS IN A
CLOSED LOW OFF THE SOUTHEASTERN UNITED STATES WHICH THEN TENDS TO
SLIDE SOUTHWESTWARD. MEANWHILE, THE WESTERLY FLOW ACROSS SOUTHERN
CANADA WILL PROBABLY SEND A SURFACE FRONT SOUTHWARD ACROSS THE
NORTHEAST AND INTO THE NORTHERN MID ATLANTIC LATER IN THE WEEKEND AS
THE RIDGE GETS KNOCKED DOWN A BIT. AS ENERGY ENTERS THE MIDWEST AND
GREAT LAKES EARLY IN THE WEEK, THE OVERALL RIDGE LOOKS TO FLATTEN
OUT WITH A COLD FRONT ARRIVING IN OUR AREA LATE TUESDAY INTO
WEDNESDAY BEFORE A SURFACE HIGH STARTS TO BUILD EASTWARD. WE
GENERALLY FAVORED A MODEL BLEND FRIDAY NIGHT THROUGH SUNDAY, THEN
SWITCHED TO HPC GUIDANCE THEREAFTER WITH SOME ADJUSTMENTS BASED ON
ADDITIONAL COLLABORATION. HPC USED THE ECMWF FOR SUNDAY NIGHT
AND MONDAY THEN THE ECMWF ENSEMBLE MEAN FOR TUESDAY ONWARD.

FOR FRIDAY NIGHT, SOME WEAKNESS ON THE NORTHERN EDGE OF THE BUILDING
RIDGE TO OUR SOUTHWEST MAY HELP WITH SOME CONVECTION ONGOING TO
START THE NIGHT. BASED ON NO REAL STRONG TRIGGER PRESENT, THE
CONVECTIVE THREAT SHOULD DWINDLE DURING THE EVENING HOURS. THE
LOW-LEVEL FLOW IS STILL RATHER LIGHT, HOWEVER IT IS FORECAST TO
BECOME MORE SOUTH OR SOUTHWEST. THIS MAY RESULT IN SOME WARMER AIR
MOVING IN ABOVE THE COOLING BOUNDARY LAYER PLUS AN UPTICK IN THE
SURFACE DEW POINTS. THIS MAY RESULT IN AREAS OF FOG AND/OR STRATUS,
AND THEREFORE THIS WAS CARRIED IN THE FORECAST. IT IS NOT CLEAR IF
DENSE FOG DEVELOPS AS WE COULD JUST HAVE STRATUS DEVELOP AND SPREAD
OUT UNDER THE STRENGTHENING LOW-LEVEL INVERSION. SOME FORECAST
SOUNDINGS INDICATE A DRY LAYER JUST ABOVE THE INVERSION, SO THIS MAY
RESULT IN MORE OF A FOG POTENTIAL. A PIECE OF ENERGY ON THE EAST
SIDE OF THE RIDGE LOOKS TO CLOSE OFF NEAR THE SOUTHEASTERN U.S.
COAST. THIS COULD DEVELOP INTO A SUBTROPICAL OR TROPICAL SYSTEM,
HOWEVER GIVEN THE FLOW IT IS FORECAST TO SLIDE WEST OR SOUTHWEST AND
AWAY FROM OUR AREA.

FOR SATURDAY AND SUNDAY, AN UPPER-LEVEL RIDGE IS FORECAST TO CREST
NORTHEASTWARD OVER THE MID ATLANTIC DURING THIS TIME. HOWEVER,
ENERGY MOVING OVER THIS RIDGE MAY ALLOW A SURFACE FRONT TO SETTLE
SOUTHWARD WITH TIME. IT IS NOT REAL CLEAR HOW FAR SOUTH THIS
LOW-LEVEL BOUNDARY GETS, ALTHOUGH THERE DOES NOT APPEAR TO BE A REAL
STRONG PUSH FROM THE NORTHEAST. THEREFORE AT THIS POINT, WE MAINLY
HELD THE SURFACE FRONT JUST TO OUR NORTH, BUT DID BRING A LITTLE BIT
OF COOLING IN FROM THE NORTHEAST ACROSS OUR NORTHERN ZONES. IN
ADDITION, A RIBBON OF FRONTOGENESIS ALONG WITH LOW-LEVEL CONVERGENCE
IN AN EAST-WEST FASHION MAY ALLOW FOR SOME CONVECTIVE CLUSTERS TO
FORM IN THE GREAT LAKES THEN SLIDE EAST/SOUTHEAST. THERE MAY BE A
BETTER CHC OF THIS OCCURRING SUNDAY ACROSS THE NORTHERN AREAS,
ALTHOUGH CONFIDENCE IS LOW REGARDING ANY SUBTLE FEATURES IN THE FLOW
THAT MAY HELP TO ORGANIZE CONVECTION. WE WILL CONTINUE WITH SOME
SLIGHT CHC TO CHC POPS ESPECIALLY ACROSS THE NORTHERN PORTIONS OF
THE CWA. BACKING UP A BIT, SATURDAY MAY START WITH LOW CLOUDS AND
FOG AS A WARM AND POSSIBLY SOUPY AIRMASS RESIDES UNDER A LOW-LEVEL
INVERSION. THIS SHOULD TEND TO MIX OUT THOUGH AS BOUNDARY LAYER
HEATING OCCURS. DUE TO A FAIR AMOUNT OF MOISTURE IN THE ATMOSPHERE,
ANY CONVECTION THAT DEVELOPS WILL BE CAPABLE OF PRODUCING LOCAL
DOWNPOURS. HIGH TEMPERATURES SHOULD NEAR 90 ESPECIALLY IN THE
INTERSTATE 95 CORRIDOR, HOWEVER DEW POINTS MAY BE LOW ENOUGH TO KEEP
THE HEAT INDICES FROM GETTING TO HIGH.

FOR MONDAY AND TUESDAY, A POTENTIALLY CONVECTIVELY INDUCED SURFACE
LOW MAY TRACK JUST TO OUR NORTH MONDAY ALONG A NEARLY STALLED
FRONTAL BOUNDARY. THIS MAY RESULT IN A CONVECTIVE CLUSTER VERY NEAR
OUR NORTHERN CWA MONDAY MORNING. AS THIS ENERGY MOVES AWAY AND A
STRONGER SHORT WAVE MOVES THROUGH THE GREAT LAKES AND OHIO VALLEY, A
RIDGE WILL BUILD EASTWARD. THIS SHOULD PRODUCE MORE OF A LULL IN THE
CONVECTIVE ACTIVE ON MONDAY ALTHOUGH A SURFACE FRONT WILL BE LURKING
NEARBY. A FEW SHOWERS OR A THUNDERSTORM CANNOT BE RULED OUT,
THEREFORE WE WILL CARRY SOME LOW POPS. FOR TUESDAY, MORE OF A
SOUTHWESTERLY FLOW LOOKS TO OCCUR WITH HIGH PRESSURE OFF THE EAST
COAST AND A COLD FRONT APPROACHING FROM THE WEST. THIS FRONT IS NOT
SCHEDULED TO ARRIVE IN OUR AREA UNTIL TUESDAY NIGHT. DESPITE THE
TIMING AT NIGHT, DECENT LIFT ASSOCIATED WITH THIS FEATURE MAY ALLOW
FOR SOME CONVECTION TO ARRIVE WITH THE COLD FRONT. THE INSTABILITY
SHOULD BE LOW ENOUGH TO KEEP ANY MORE ROBUST UPDRAFTS IN CHECK.
HIGHS SHOULD TOP OUT NEAR 90 FOR SEVERAL AREAS WITH PERHAPS THIS
TIME FRAME LOOKING TO BE THE HOTTEST. THE DEW POINTS MAY REMAIN JUST
LOW ENOUGH TO KEEP THE HEAT INDICES FROM REACHING 100 DEGREES.
HOWEVER, LOW TEMPERATURES ESPECIALLY IN THE URBAN CENTERS MAY NOT
DROP BELOW 70 DEGREES. WE WILL KEEP A MENTION OF THE HEAT IN THE
HAZARDOUS WEATHER OUTLOOK.

FOR WEDNESDAY AND THURSDAY, AN UPPER-LEVEL TROUGH MOVING ACROSS THE
NORTHEAST WILL DRIVE A COLD FRONT TO OUR EAST EARLY WEDNESDAY. HIGH
PRESSURE ACROSS THE MIDWEST WILL THEN START TO BUILD EASTWARD INTO
THURSDAY AS THE MAIN TROUGH FLATTENS OUT AND THE FLOW TURNS MORE
ZONAL. AS A RESULT, THE FRONTAL BOUNDARY SHOULD BE PUSHED FAR ENOUGH
TO OUR SOUTH WITH SOME COOLER AND DRIER AIR ACROSS THE BULK OF OUR
CWA.

&&

.AVIATION /20Z THURSDAY THROUGH TUESDAY/...
THE FOLLOWING DISCUSSION IS FOR KPHL, KPNE, KTTN, KABE, KRDG, KILG,
KMIV, KACY AND SURROUNDING AREAS.

NEED TO CONTEND WITH SOME SHOWERS AND THUNDERSTORMS THIS AFTERNOON.
SOUTHEAST WINDS WILL GO LIGHT THIS EVENING. FOG AND STRATUS ARE
FORECAST TO RETURN. IFR CONDITIONS EXPECTED AFTER 07Z. CAN'T RULE
OUT LIFR. SOME IFR/MVFR COULD PERSIST INTO THE LATTER PART OF
TOMORROW MORNING ACROSS THE LEHIGH VALLEY AND SOUTHERN POCONOS.

OUTLOOK...
FRIDAY NIGHT...GENERALLY VFR TO START, HOWEVER SUB-VFR CONDITIONS
MAY DEVELOP LATE DUE TO SOME STRATUS AND/OR FOG. A LIGHT SOUTHERLY
WIND.

SATURDAY AND SUNDAY...SOME LOW CLOUDS/FOG POSSIBLE TO START EACH DAY
OTHERWISE VFR. A FEW SHOWERS OR A THUNDERSTORM CANNOT BE RULED OUT
ESPECIALLY EACH AFTERNOON AND EARLY EVENING.

MONDAY AND TUESDAY...THERE COULD BE POCKETS OF SUB-VFR DUE TO SOME
SHOWERS AND THUNDERSTORMS. IT APPEARS THE BETTER CHANCE OF THIS
OCCURRING WOULD BE LATER TUESDAY. SOUTHERLY WINDS AROUND 10 KNOTS.

&&

.MARINE...
SOUTHEAST WINDS WILL PERSIST THROUGH THE OVERNIGHT. SEAS WILL BE IN
THE 3 TO 4 FEET RANGE ON THE OCEAN AND 1 TO 3 FEET ON DELAWARE BAY.
WINDS WILL GO SOUTH TOMORROW AND INCREASE SLIGHTLY. NO SIGNIFICANT
CHANGE IN SEAS.

NO HEADLINES FOR THE SHORT TERM.

OUTLOOK...
THERE MAY BE SOME FOG LATE FRIDAY NIGHT AND EARLY SATURDAY MORNING,
HOWEVER THIS SHOULD MIX OUT DURING THE DAY SATURDAY. A FRONTAL
BOUNDARY SHOULD STALL TO OUR NORTH LATER THIS WEEKEND INTO EARLY
NEXT WEEK, WHICH WILL MAINTAIN A SOUTHERLY FLOW ACROSS OUR AREA.
THIS FLOW SHOULD INCREASE SOME SUNDAY THROUGH TUESDAY AS HIGH
PRESSURE SETTLES TO OUR EAST AND A COLD FRONT APPROACHES DURING
TUESDAY. IT DOES APPEAR THAT THE WIND SPEEDS REMAIN UNDER SMALL
CRAFT ADVISORY CRITERIA HOWEVER DUE TO A MUCH WARMER AIRMASS OVER
THE COOLER WATERS. THE SOUTHERLY FLOW HOWEVER MAY BUILD THE SEAS TO
NEAR 5 FEET WITH TIME, HOWEVER OUR CONFIDENCE IS ON THE LOWER SIDE.
SOME THUNDERSTORMS MAY OCCUR SATURDAY THROUGH TUESDAY, HOWEVER MOST
MAY END UP OCCURRING OVER LAND WITH A BETTER CHC ACROSS THE WATERS
PROBABLY OCCURRING LATE SUNDAY OR LATE TUESDAY.
