Special Weather Statement, NWS Philadelphia/Mount Holly

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE MOUNT HOLLY NJ
1212 PM EDT TUE JUN 16 2015

.SYNOPSIS...
A COLD FRONT WILL DROP DOWN THROUGH THE GREAT LAKES REGION, CROSSING
OUR AREA BY LATE TUESDAY. HIGH PRESSURE WILL SLIDE ACROSS TO OUR
NORTH ON WEDNESDAY. A WARM FRONT WILL THEN MOVE THROUGH OUR AREA ON
THURSDAY, FOLLOWED BY A COLD FRONT ON FRIDAY, WITH THE FRONT
STALLING JUST TO THE SOUTH OF THE AREA. HIGH PRESSURE RETURNS FOR
SATURDAY. A WARM FRONT WILL MOVE THROUGH ON SUNDAY FOLLOWED BY A
COLD FRONT CROSSING THE REGION ON MONDAY.

&&

.NEAR TERM /UNTIL 6 PM THIS EVENING/...
THE WARM FRONT DRAPED ACROSS NORTHEAST PENNSYLVANIA AND CENTRAL
NEW JERSEY IS SLOWLY MOVING NORTHWARD AND SHOULD CONTINUE TO LIFT
NORTHWARD INTO THE EARLY AFTERNOON AS THE SOUTHWESTERLY FLOW AT
THE SURFACE AND ALOFT SHOULD HELP SPEED IT UP SOON. ONCE THIS
MOVES THROUGH, SKIES WILL PARTIALLY CLEAR FOR MANY AREAS,
ESPECIALLY ACROSS THE SOUTH. THIS WILL ALLOW TEMPERATURES TO WARM
SHARPLY, SO WE BUMPED HIGHS FOR MOST AREAS BY A COUPLE OF DEGREES.
LIKE YESTERDAY, TEMPS WILL TOP OUT IN THE UPPER 80S TO LOW 90S IN
MANY AREAS. HEAT INDEX VALUES WILL TOP OUT IN THE MID 90S IN MANY
AREAS WITH DEW POINTS MOSTLY IN THE UPPER 60S TO LOW 70S.

A COLD FRONT WILL PROGRESS ACROSS CENTRAL PENNSYLVANIA THROUGH
THE DAY AND INTO OUR AREA BY THIS AFTERNOON, BRINGING SHOWERS AND
THUNDERSTORMS WITH IT. SCATTERED SHOWERS ARE DEVELOPING AHEAD OF
THE FRONT ALONG A PRE-FRONTAL TROUGH, AND IT IS POSSIBLE A FEW
THUNDERSTORMS COULD DEVELOP WITH THIS INITIAL BATCH OF CONVECTION.

SPC HAS BUMPED MUCH OF THE AREA INTO A SLIGHT RISK FOR SEVERE
WEATHER TODAY. HEAVY RAINS AND GUSTY WINDS ARE THE PRIMARY HAZARDS
TODAY. LOCALIZED FLOODING CANNOT BE RULED OUT. THE CELLS WILL
PROBABLY KEEP ENOUGH FORWARD MOTION TO PRECLUDE NAY SIGNIFICANT
FLASH FLOOD THREAT...SO WE WILL NOT CONSIDER ANY FF HEADLINES
ATTM.

&&

.SHORT TERM /6 PM THIS EVENING THROUGH 6 AM WEDNESDAY/...
THE FRONT WILL MOVE OFFSHORE TONIGHT AND SHOWERS AND TSTMS WILL MOVE
EAST ALONG WITH IT. DRIER AND COOLER AIR WILL OVERSPREAD THE AREA ON
A WRLY/NWRLY WIND TONIGHT. LOW TEMPERATURES WILL BOTTOM OUT IN THE
LOW/MID 60S NORTH AND UPPER 60S/LOW 70S SOUTH.

&&

.LONG TERM /WEDNESDAY THROUGH MONDAY/...
WEDNESDAY...WITH THE FRONT MOVING THROUGH THE REGION, WE SHOULD SEE
SOME COOLER AIR FILTER IN AND MAKE IT A BIT MORE COMFORTABLE
OUTSIDE. WITH THE HIGH SLIDING ACROSS TO OUR NORTH, WE SHOULD HAVE A
DRIER DAY THAN WE HAVE SEEN LATELY. HOWEVER, OVERNIGHT SHOWERS LOOK
TO DEVELOP IN ADVANCE OF THE WARM FRONT.

THURSDAY...THE WARM FRONT MAKES IT THROUGH THE AREA AND SHOWERS AND
ISOLATED THUNDERSTORMS WILL ONCE AGAIN BE THE THEME OF THE DAY. BEST
CHANCES LOOK TO BE AWAY FROM THE COAST. THE WARMER MOISTER AIR
BEHIND THE WARM FRONT WILL BRING US BACK INTO A MORE DIURNALLY
DRIVEN SCENARIO WITH SOME SHORT WAVES ROTATING THROUGH THE MID LEVEL
FLOW PROVIDING ANOTHER SOURCE OF LIFT.

THURSDAY NIGHT THROUGH FRIDAY...A COLD FRONT WILL DROP DOWN FROM THE
NORTHWEST THURSDAY NIGHT AND PUSH THROUGH OUR AREA BY FRIDAY,
STALLING TO OUR SOUTH. THIS LOOKS TO BRING A MORE WIDESPREAD RAIN TO
THE REGION, WITH THUNDERSTORMS.

SATURDAY THROUGH MONDAY...HIGH PRESSURE RETURNS FOR SATURDAY WITH
ANOTHER WARM FRONT SLATED TO PUSH THROUGH OUR AREA ON SUNDAY AND A
COLD FRONT ON MONDAY. IT ALMOST FEELS LIKE A WASH, RINSE, REPEAT
CYCLE FOR OUR AREA. SATURDAY LOOKS DRY WITH BOTH SUNDAY AND MONDAY
HAVING CHANCES FOR SHOWERS AND THUNDERSTORMS. IT DOESN'T LOOK LIKE A
COMPLETE WASHOUT BUT STORMS WILL LIKELY BE AROUND BOTH DAYS.

SOMETHING TO KEEP AN EYE ON THROUGH THE WEEK, WILL BE WHAT HAPPENS
TO THE REMNANT MOISTURE OF TROPICAL STORM BILL. AS THAT SYSTEM MOVES
INTO TEXAS, THE MOISTURE LOOKS TO BE PULLED ACROSS THE MIDWEST AND
THEN INTO OUR REGION AND DEPENDING ON WHICH MODEL YOU PREFER, THE
WEEKEND APPEARS TO BE WHEN WE WILL SEE IT ARRIVE. PWATS JUMP UP
DURING THIS TIME FRAME AND INTO THE 2+ INCH RANGE. HEAVY RAIN WILL
BE A CONCERN AND SOMETHING WE WILL NEED TO MONITOR IN THE COMING
DAYS. LOTS AND LOTS OF UNCERTAINTY AT THIS TIME AS THE MODELS HANDLE
THE REMNANT TROPICAL MOISTURE DIFFERENTLY.

&&

.AVIATION /16Z TUESDAY THROUGH SATURDAY/...
THE FOLLOWING DISCUSSION IS FOR KPHL, KPNE, KTTN, KABE, KRDG, KILG,
KMIV, KACY, AND SURROUNDING AREAS.

CONDITIONS HAVE IMPROVED TO VFR FOR ALL TAF SITES.

A COLD FRONT WILL MOVE ACROSS THE AREA LATER THIS AFTERNOON,
BRINGING SCATTERED SHOWERS AND THUNDERSTORMS TO THE AREA. ALSO,
SCATTERED SHOWERS ARE DEVELOPING ALONG A PRE-FRONTAL TROUGH, WHICH
WILL MOVE ACROSS THE AREA AHEAD OF THE COLD FRONT. ANY
SHOWERS/THUNDERSTORMS THAT IMPACT THE TAF SITES COULD TEMPORARILY
BRING REDUCED CIGS/VSBYS

WINDS BEHIND THE WARM FRONT HAVE SWITCHED TO SOUTHWEST, WHILE
NORTH OF THE WARM FRONT THEY ARE MORE SOUTHEASTERLY. ALL SITES
SHOULD BECOME SOUTHWESTERLY BY THE AFTERNOON AND BEGIN GUSTING
AROUND 20 KNOTS.

VFR TONIGHT WITH NW WINDS EXPECTED.

OUTLOOK...
WEDNESDAY...MAINLY VFR CONDITIONS EXPECTED.

WEDNESDAY NIGHT THROUGH THURSDAY NIGHT...MVFR CONDITIONS EXPECTED
WITH IFR OR LOWER IN SHOWERS/THUNDERSTORMS/FOG, ESPECIALLY
THURSDAY MORNING. SHOWERS AND THUNDERSTORMS REMAIN POSSIBLE INTO
THURSDAY NIGHT WITH MVFR/IFR CONDITIONS.

FRIDAY THROUGH SATURDAY...MAINLY VFR CONDITIONS EXPECTED. ISOLATED
TO SCATTERED SHOWERS AND THUNDERSTORMS WITH MVFR OR LOWER CONDITIONS
POSSIBLE.

&&

.MARINE...
VISIBILITIES ARE EXPECTED TO CONTINUE TO IMPROVE THIS AFTERNOON,
SO THE DENSE FOG HAS BEEN ALLOWED TO EXPIRE.

NO ADDITIONAL MARINE FLAGS EXPECTED TODAY OR TONIGHT. SMW'S
POSSIBLE LATER TODAY WITH A COLD FRONT AND SHOWERS/TSTMS EXPECTED
TO ACCOMPANY IT. SOME WIND GUSTS 30 TO 40 KTS POSSIBLE WITH A FEW
OF THE TSTMS. OTHER THAN THAT...MOSTLY SWRLY/WRLY WINDS TODAY AND
WRLY/NWRLY WINDS TONIGHT. SEAS MOSTLY 2-3 FT ON THE OCEAN AND
1-2FT OVER DEL BAY. HIGHER WINDS AND SEAS NEAR TSTMS.

OUTLOOK...

WEDNESDAY THROUGH SATURDAY...SEAS WILL REMAIN BETWEEN 2-4 FEET WITH
WINDS REMAINING BELOW 25 KNOTS. SHOWERS AND THUNDERSTORMS WILL
REMAIN POSSIBLE THROUGH MUCH OF THE WEEK.

&&

.RIP CURRENTS...
AT THIS POINT WE ARE EXPECTING THE RIP CURRENT THREAT FOR TOMORROW
TO BE LOW. HOWEVER, AN UNDERLYING LONG PERIOD SWELL AND THE NEW
MOON CYCLE MEANS THE RISK IS JUST ON THE EDGE OF LOW TO MODERATE.
THUS...WILL WATCH CLOSELY OBSERVATIONS THAT WE GET TOMORROW
MORNING.

&&

.PHI WATCHES/WARNINGS/ADVISORIES...
PA...NONE.
NJ...NONE.
DE...NONE.
