Special Weather Statement, NWS Philadelphia/Mount Holly

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE MOUNT HOLLY NJ
650 PM EDT TUE JUL 21 2015

.SYNOPSIS...
A COLD FRONT WILL MOVE ACROSS OUR AREA TONIGHT, THEN HIGH PRESSURE
BUILDS IN DURING WEDNESDAY. THIS HIGH PRESSURE SYSTEM IS FORECAST TO
REMAIN IN PLACE THROUGH FRIDAY. HOWEVER, A WEAK COLD FRONT ARRIVES
FROM THE NORTH FRIDAY THEN RETURNS NORTHWARD AS A WARM FRONT LATE
SATURDAY. A POTENTIALLY WEAKENING COLD FRONT IS THEN FORECAST TO
MOVE THROUGH OUR REGION LATE SUNDAY INTO MONDAY AS HIGH PRESSURE
RETURNS FOR TUESDAY.

&&

.NEAR TERM /UNTIL 6 AM WEDNESDAY MORNING/...
ESTF: SEVERAL UPDATES TO THE PRODUCTS SINCE 456PM IN AN ATTEMPT
TO BETTER CAPTURE THE ACTIVITY MOVING SEWD TOWARD I-95, THIS MARKING
THE CFP. GUSTY NW OUTFLOW WINDS 30-40KT. NON SVR SO FAR. PWAT
STILL 1.5 BUT DROPS SHARPLY WITH THE WSHIFT TO NW THIS EVENING.

LINE MOVING SEWD 22-29 KT.

AT LEAST PARTIALLY CLEARS AFTER THE FROPA AND BETTER SLEEPING
NIGHT LATE.

OVERNIGHT MINIMUM TEMPERATURES WILL BE MORE COMFORTABLE THAN RECENT
NIGHTS, AS LOWS RANGE FROM THE UPPER 50S IN THE NORTH TO MOSTLY
THE UPPER 60S ELSEWHERE.

&&

.SHORT TERM /6 AM WEDNESDAY MORNING THROUGH 6 PM WEDNESDAY/...
WITH THE PREVIOUSLY MENTIONED COLD FRONT MOVING FARTHER OFFSHORE
THROUGH THE DAYTIME WEDNESDAY, INCOMING HIGH PRESSURE CENTERED OVER
THE GREAT LAKES AND MIDWEST STATES WILL GRADUALLY BE BUILDING
EASTWARD TOWARD OUR REGION. A NOTICEABLY COOLER AND DRIER AIRMASS
WILL CONTINUE TO OVERSPREAD THE REGION ON WEST-NORTHWEST WINDS.
AMPLE SUNSHINE IS ANTICIPATED THROUGH THE DAY, WITH PERHAPS A FEW
AFTERNOON CUMULUS DEVELOPING. IN ADDITION, DEW POINTS WILL BE
DROPPING INTO THE 50S THROUGH THE COURSE OF THE DAY, GIVING THE AREA
RELIEF FROM THE HUMIDITY. A BLEND OF MET/MAV GUIDANCE PUTS AFTERNOON
HIGH TEMPERATURES MAINLY INTO THE 80S ACROSS THE REGION, WITH
PERHAPS THE HIGHER TERRAIN IN THE POCONOS ONLY REACHING THE MID TO
UPPER 70S.

&&

.LONG TERM /WEDNESDAY NIGHT THROUGH TUESDAY/...
THE SYNOPTIC SETUP IS COMPRISED OF A STRONG UPPER-LEVEL TROUGH IN
SOUTHEASTERN CANADA AND THE NORTHEAST WEDNESDAY NIGHT AND THURSDAY,
WHICH THEN SHIFTS EAST SOME INTO FRIDAY. THIS FEATURE SHOULD SHIFT
EAST LATER FRIDAY AS A SHORT WAVE TROUGH DIVES SOUTHEASTWARD FROM
THE MIDWEST. THIS TROUGH SHOULD AMPLIFY THE MAIN UPPER-LEVEL TROUGH
ONCE AGAIN ACROSS THE NORTHEAST OVER THE WEEKEND, WITH SOME
RELAXATION POSSIBLE EARLY NEXT WEEK. THERE ARE SOME HINTS WITHIN THE
GUIDANCE THAT A STRONG RIDGE ACROSS THE PLAINS MAY START TO EXPAND
NORTHEASTWARD NEXT WEEK INTO THE MID ATLANTIC. WE USED A MODEL BLEND
FOR WEDNESDAY NIGHT THROUGH FRIDAY, THEN WENT WITH THE 12Z WPC
GUIDANCE. SOME ADJUSTMENTS WERE THEN MADE FOLLOWING ADDITIONAL
COLLABORATION WITH OUR NEIGHBORING OFFICES.

FOR WEDNESDAY NIGHT...AN UPPER-LEVEL TROUGH IS IN PLACE, HOWEVER
SURFACE HIGH PRESSURE IS FORECAST TO BUILD OVER THE AREA. THIS
SHOULD RESULT IN LESS CLOUDINESS AND A DIMINISHING WIND ALONG WITH
MUCH COOLER TEMPERATURES.

FOR THURSDAY AND FRIDAY...HIGH PRESSURE OVER THE AREA GRADUALLY
WEAKENS DURING THIS TIME FRAME, HOWEVER AN AIRMASS CHARACTERIZED BY
LOW HUMIDITY LEVELS IS ANTICIPATED TO REMAIN FOR MUCH OF THE AREA.
AN UPPER-LEVEL TROUGH IS FORECAST TO AMPLIFY ACROSS THE NORTHEAST AS
SHORT WAVE ENERGY DIGS INTO ITS BASE. THIS IS MOST NOTED ACROSS NEW
ENGLAND WHERE THE COLD POOL ALOFT IS MORE PRONOUNCED. THE COOLING
ALOFT MAY ALLOW FOR A BIT MORE CLOUDINESS ACROSS OUR NORTHERN AREAS
ESPECIALLY ON FRIDAY, HOWEVER IT APPEARS THAT ANY SHOWER CHC IS
RATHER LOW. A SOUTHERN TRACKING SHORT WAVE THOUGH MAY ALLOW FOR A
WEAK SURFACE LOW TO DEVELOP ALONG A FRONTAL BOUNDARY TO OUR SOUTH.
GIVEN THE ORIENTATION OF THE UPPER-LEVEL TROUGH AND A SEPARATE
BOUNDARY ARRIVING FROM THE NORTH, THIS FEATURE SHOULD REMAIN FAR
ENOUGH TO OUR SOUTH. AS A RESULT, WE CONTINUED WITH A DRY FORECAST.

FOR SATURDAY AND SUNDAY...SOME UPPER-LEVEL RIDGING SHOULD MOVE
ACROSS THE AREA ON SATURDAY AND A WARM FRONT MAY LIFT NORTH AS A
RESULT. LOW PRESSURE IS FORECAST TO TRACK WELL TO OUR NORTH LATE
SATURDAY AND SUNDAY, WITH AN ASSOCIATED COLD FRONT MOVING OUR WAY
LATE SUNDAY. THE FRONT ITSELF MAY BEGIN TO WEAKEN, HOWEVER A
POSSIBLE PRE-FRONTAL TROUGH MAY HELP FOCUS SOME CONVECTION AS WAA
OCCURS IN CONJUNCTION WITH SOME MOISTURE RETURN. THE MAIN PORTION
OF THE UPPER-LEVEL TROUGH IS FORECAST TO TRACK FARTHER NORTH,
THEREFORE MUCH OF THE LIFT FOR ORGANIZED CONVECTION COULD BE
FARTHER NORTH AS WELL. WE FAVORED WPC GUIDANCE WHICH CARRIES CHC
POPS ON SUNDAY ESPECIALLY IN THE AFTERNOON AND EVENING.

FOR MONDAY AND TUESDAY...A FRONTAL BOUNDARY OR LINGERING SURFACE
TROUGH IN OUR VICINITY MIGHT BE ABLE TO FORCE SOME CONVECTION
MONDAY, AS OUR AREA REMAINS INFLUENCED BY AN UPPER-LEVEL TROUGH
MIGRATING ACROSS THE NORTHEAST. THE UPPER-LEVEL TROUGH REMAINS ON
TUESDAY, ALTHOUGH WEAK SURFACE HIGH PRESSURE IS CURRENTLY FORECAST
TO BE NEARBY. FOR NOW, WE INCLUDED A SLIGHT CHC POP IN THE GRIDDED
DATABASE/FORECAST.

&&

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

OUTLOOK...
WEDNESDAY NIGHT...VFR WITH NORTHWEST WINDS DIMINISHING TO 5 KNOTS OR

&&

.MARINE...
SUB-ADVISORY CONDITIONS ARE EXPECTED ON THE AREA WATERS TONIGHT AND
THROUGH THE DAYTIME WEDNESDAY. HOWEVER, SOME SCATTERED SHWRS/TSTORMS
ARE POSSIBLE THROUGH TONIGHT ASSOCIATED WITH A COLD FRONT,
ESPECIALLY FOR THE SOUTHERN COASTAL WATERS, YIELDING POSSIBLE BRIEF
HIGHER WINDS AND/OR SEAS. FOLLOWING THE COLD FRONT PASSAGE AROUND
MIDNIGHT OR SO ACROSS THE WATERS, A WIND SHIFT TO THE NORTHWEST IS
ANTICIPATED. DURING THE DAYTIME WEDNESDAY THE WEST-NORTHWEST WINDS
COULD GUST AROUND 20 KNOTS AT TIMES, ESPECIALLY FOR THE COASTAL
WATERS.

OUTLOOK...
WEDNESDAY NIGHT AND THURSDAY...THE CONDITIONS ARE EXPECTED TO BE
BELOW SMALL CRAFT ADVISORY CRITERIA AS HIGH PRESSURE BUILDS IN. THIS
WILL RESULT IN SOME DECREASE IN THE WINDS.

FRIDAY THROUGH SUNDAY...A WEAK FRONT ARRIVES FROM THE NORTH FRIDAY
HOWEVER IT THEN LOOKS TO LIFT BACK NORTH AS A WARM FRONT LATER
SATURDAY. A SOUTHERLY WIND SHOULD INCREASE SUNDAY AHEAD OF A COLD
FRONT, HOWEVER THE CONDITIONS OVERALL SHOULD REMAIN BELOW SMALL
CRAFT ADVISORY CRITERIA.
