Special Weather Statement, NWS Philadelphia/Mount Holly

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE MOUNT HOLLY NJ
1252 AM EDT TUE APR 26 2016

.SYNOPSIS...
A NEARLY STATIONARY FRONT WILL REMAIN IN NORTHEASTERN
PENNSYLVANIA AND NORTHERN NEW JERSEY THROUGH MORNING. AN AREA OF
LOW PRESSURE IS EXPECTED TO TRACK ALONG THIS FRONT AND CROSS THE
REGION TUESDAY AFTERNOON. THE FRONT WILL FINALLY PROGRESS
SOUTHWARD THROUGH THE AREA TUESDAY AFTERNOON AND NIGHT. HIGH
PRESSURE BUILDS IN FROM CENTRAL CANADA WEDNESDAY. ANOTHER WAVE OF
LOW PRESSURE IS FORECAST TO MOVE ALONG THE FRONT, SLIDING JUST
SOUTH OF OUR AREA THURSDAY NIGHT INTO FRIDAY. HIGH PRESSURE
RETURNS SATURDAY BEFORE YET ANOTHER LOW PRESSURE SYSTEM APPROACHES
FROM THE WEST SUNDAY AND MONDAY.

&&

.NEAR TERM /UNTIL 6 AM THIS MORNING/...
THE PRIMARY AREA OF SHOWERS ASSOCIATED WITH THE WARM ADVECTION
WAS MOVING EASTWARD ACROSS NORTHEASTERN AND CENTRAL PENNSYLVANIA
AROUND MIDNIGHT. IT WILL PASS THROUGH THE NORTHERN HALF OF OUR
FORECAST AREA DURING THE BALANCE OF THE NIGHT.

MEANWHILE, ADDITIONAL SCATTERED SHOWERS AND ISOLATED
THUNDERSTORMS DEVELOPED ACROSS NORTHEASTERN MARYLAND, NORTHERN
DELAWARE AND SOUTHEASTERN PENNSYLVANIA. BASED ON THE LATEST HRRR
RUN, THIS ACTIVITY IS EXPECTED TO DRIFT THROUGH SOUTHERN NEW
JERSEY AND OFF THE COAST BEFORE DAYBREAK. ONE PARTICULARLY ROBUST
THUNDERSTORM PRODUCED HAIL IN THE WILMINGTON AREA AROUND 1230 AM.

A LIGHT SOUTHEAST TO SOUTH WIND IS ANTICIPATED OVERNIGHT AND
TEMPERATURES SHOULD REMAIN MILD STAYING IN THE 50S AND 60S.

&&

.SHORT TERM /6 AM THIS MORNING THROUGH 6 AM WEDNESDAY/...
A POSSIBLE CONVECTIVELY ACTIVE END TO THE DAY ACROSS THE AREA.
THIS WILL BE DUE TO A STRONG SHORT WAVE SLIDING SOUTHEASTWARD FROM
THE GREAT LAKES IN THE AFTERNOON. THIS WILL DRIVE A WEAK SURFACE
LOW ALONG A FRONTAL BOUNDARY THAT WILL BE DRAPED EAST-WEST ACROSS
MOSTLY OUR NORTHERN ZONES. THE PLACEMENT OF THIS FRONT WILL HAVE
AN IMPACT ON TEMPERATURES, AND THERE VERY WELL COULD BE QUITE THE
GRADIENT FROM SOUTH TO NORTH IN THE AFTERNOON.

AS THE STRONG SHORT WAVE ARRIVES IN THE AFTERNOON, AN AREA OF
ENHANCED MID LEVEL FLOW WILL MOVE INTO OUR AREA. THIS COMBINED
WITH ENOUGH INSTABILITY /DESPITE SOME CLOUD COVER/ SHOULD RESULT
IN AT LEAST SCATTERED CONVECTIVE DEVELOPMENT IN THE AFTERNOON.
REWINDING A BIT, THERE COULD BE SOME SHOWERS OR A THUNDERSTORM IN
THE EARLY MORNING ESPECIALLY NEAR AND NORTH OF PHILADELPHIA AS A
LEAD IMPULSE MOVES THROUGH COMBINED WITH AN UPTICK IN INSTABILITY.
BACK TO THE AFTERNOON, THE FORECAST SOUNDINGS SHOW A DEEP
UNIDIRECTIONAL WIND PROFILE WHICH WOULD PROMOTE LINE SEGMENTS AND
CLUSTERS. GIVEN THE FORECAST FLOW, LOCALLY STRONG WINDS COULD
OCCUR ESPECIALLY WITH MORE ORGANIZED LINE SEGMENTS. IF ENOUGH
INSTABILITY CAN BE REALIZED, SOME HAIL CANNOT BE RULED OUT. THE
AMOUNT OF INSTABILITY THAT CAN BE ACHIEVED THROUGH THE AFTERNOON
WILL BE THE MAIN DRIVING PARAMETER FOR THE STRENGTH OF THE
CONVECTION. GIVEN THE FLOW AND FORCING DURING THE AFTERNOON, WE
ADDED IN A GUSTY WIND MENTION TO THE FORECAST. THIS IS ESPECIALLY
FOR ABOUT THE SOUTHERN HALF OF THE CWA WHERE THE BOUNDARY LAYER
WILL BE WARMER, AND THE FORECAST SOUNDINGS INDICATE A LOW-LEVEL
INVERTED-V SIGNATURE DEVELOPING. THE PW VALUES ARE FORECAST TO BE
IN THE 1.2-1.5 INCH RANGE, THEREFORE LOCAL DOWNPOURS WILL
ACCOMPANY THE CONVECTION. TT BEING MODELED INTO THE LOWER 50S MAY
PERMIT SOME SMALL HAIL. ONE SMALL ARGUMENT AGAINST WIDESPREAD AFTN
CONVECTION SE PA AND S NJ IS THE STIFF WLY FLOW AT 850 MB.

AS FOR THE HIGH TEMPERATURES, WE USED A MOS BLEND TO START THEN
BUMP THESE UP A BIT ESPECIALLY ACROSS THE SOUTHERN AREAS WHERE
BETTER HEATING MAY TAKE PLACE. GIVEN MORE CLOUD COVER AND A NEARBY
BOUNDARY, LOWERED TEMPERATURES A BIT ACROSS THE FAR NORTHERN
LOCALS.

&&

.LONG TERM /WEDNESDAY THROUGH TUESDAY/...
THE COLD FRONT WILL CONTINUE TO PROGRESS SOUTHWARD THROUGH THE
FORECAST AREA TUESDAY EVENING. ALTHOUGH ENHANCED LIFT ASSOCIATED
WITH THE MID-LEVEL SHORTWAVE TROUGH IS FORECAST TO MOVE OFFSHORE
BY SUNSET, SHOWERS AND THUNDERSTORMS WILL PERSIST LATER INTO THE
EVENING AS ADDITIONAL FORCING ACROSS THE SOUTHERN HALF OF THE
FORECAST AREA IS FAVORED IN THE RIGHT-ENTRANCE REGION OF AN UPPER-
LEVEL JET STREAK. THE THREAT OF STRONG TO SEVERE THREAT MAY
PERSIST THE FIRST HALF OF THE EVENING ACROSS FAR SE PA/S NJ AND
THE DELMARVA, ESPECIALLY IF THE UNSTABLE WARM SECTOR SOUTH OF THE
FRONT HAS NOT BEEN WORKED OVER.

THE COLD FRONT WILL MOVE SOUTH OF THE DELMARVA LATE TUESDAY NIGHT
AND THEN BECOME STATIONARY NEAR THE NC-VA BORDER WEDNESDAY. DRIER
AND COOLER AIR WILL WORKS ITS WAY INTO THE REGION AS CANADIAN HIGH
PRESSURE CENTERED NEAR THE NORTHWEST PASSAGES RIDGES DOWN TOWARD
US. HOWEVER, THE DRIER AIR MAY STRUGGLE TO MAKE IT INTO OUR FAR
SOUTHERN ZONES, RESULTING IN CLOUDY SKIES THAT PERSIST INTO MOST
OF WEDNESDAY ACROSS THE DELMARVA.

LEE CYCLOGENESIS IS CURRENTLY TAKING PLACE IN THE CO FRONT RANGE
OF THE ROCKIES. THIS SURFACE LOW WILL MEANDER OVER THE CENTRAL
PLAINS FOR THE NEXT FEW DAYS AS THE UPPER TROUGH TIED TO THE
SURFACE LOW REMAINS CUTS OFF. THE CUTOFF LOW IS FORECAST TO
EVENTUALLY WEAKEN AND BECOME AN OPEN WAVE BY THURSDAY. IN RESPONSE
TO THE EVOLVING UPPER PATTERN, THE SURFACE LOW WILL PROGRESS
EASTWARD ALONG THE STATIONARY BOUNDARY TO OUR SOUTH ON THURSDAY. A
SECONDARY WAVE OF LOW PRESSURE MAY DEVELOP AND RIDE THE FRONT ON
FRIDAY. OVERRUNNING PRECIP SHOULD EXPAND NORTHWARD LATE WEDNESDAY
NIGHT INTO THURSDAY AS THE FLOW BACKS MORE OUT OF THE SOUTH AHEAD
OF THE LOW AND ISENTROPIC LIFT STRENGTHENS ALONG AND ON THE COOL
SIDE OF THE BOUNDARY. THERE IS STILL UNCERTAINTY REGARDING HOW FAR
NORTH THE FRONT AND PRECIP ADVANCES WITH DRIER AIR BEING
REINFORCED BY HIGH PRESSURE ANCHORED TO OUR NORTH. THERE IS SOME
EVIDENCE FROM GUIDANCE THAT EVAPORATIVE COOLING AT THE ONSET COULD
LEAD TO A COLD AIR DAMMING PATTERN IF THERE IS ENOUGH LOW-LEVEL
DRY AIR IN PLACE WHEN THE OVERRUNNING PRECIP MOVES IN. THIS WOULD
KEEP THE FORECAST AREA ON THE COLD SIDE OF THE BOUNDARY. WE WILL
CONTINUE TO SHOW THE HIGHEST POPS ACROSS OUR SOUTHERN AREAS DUE TO
THE PROXIMITY OF THE FRONT.

SATURDAY LOOKS DRY AS HIGH PRESSURE BRIEFLY BUILDS BACK INTO THE
MID ATLANTIC. SHOWERS MAY RETURN SUNDAY INTO MONDAY AS YET ANOTHER
WAVE OF LOW PRESSURE IS EXPECTED TO ORGANIZE OVER THE GREAT PLAINS
AND TRACK EASTWARD ALONG THE STATIONARY FRONT.

&&

.AVIATION /06Z TUESDAY THROUGH SATURDAY/...
THE FOLLOWING DISCUSSION IS FOR KPHL, KPNE, KTTN, KABE, KRDG,
KILG, KMIV, KACY AND SURROUNDING AREAS.

REMAINDER OF THE NIGHT...VFR OVERALL, WITH CEILINGS DEVELOPING
AND LOWERING TO 5000 FT, ESPECIALLY LATE. SCATTERED SHOWERS AND
ISOLATED THUNDERSTORMS. SOUTHWEST TO LOCALLY SOUTH- SOUTHEAST
WINDS LESS THAN 10 KNOTS.

TUESDAY...A FEW SHOWERS AND POSSIBLY A THUNDERSTORM AROUND EARLY
IN THE MORNING, ESPECIALLY NNJ. ADDITIONAL SHOWERS WITH SCATTERED
THUNDERSTORMS ARE EXPECTED BY LATE AFTERNOON. SOME THUNDERSTORMS
COULD PRODUCE LOCALLY BRIEF STRONG WIND GUSTS. THE VISIBILITY WILL
BE REDUCED DURING SOME SHOWERS AND THUNDERSTORMS DUE TO DOWNPOURS.
GIVEN SOME UNCERTAINTY WITH THE TIMING, DID NOT SIGNIFICANTLY
LOWER THE VISIBILITY AT THIS TIME. SOUTHWESTERLY WINDS INCREASE TO
10-15 KNOTS, WITH SOME LOCALLY HIGHER GUSTS TO 25 KT ESPECIALLY
FROM THE KPHL AREA ON SOUTH AND EAST.

OUTLOOK...
TUESDAY NIGHT...THE THREAT OF SHRA AND TSRA SHOULD PERSIST INTO
THE EVE FOR THE PHILA TERMINALS AND ESPECIALLY SOUTH. THE
CONVECTION WILL BE ASSOCIATED WITH A COLD FRONT THAT IS MOVING SWD
THRU THE TERMINALS DURING THE EVENING. FROPA WILL BE MARKED BY A
WIND SHIFT FROM W-SW TO N-NE. EXPECT RESTRICTIONS MVFR OR LOWER
BRIEFLY WHEN THESE STORMS MOVE THRU. IMPROVING TO VFR OVERNIGHT.

WEDNESDAY AND WEDNESDAY NIGHT...MAINLY VFR.

THURSDAY THROUGH FRIDAY...SHOWERS RETURN. BEST CHANCE FOR SHOWERS
AND MVFR RESTRICTIONS WOULD BE ACROSS THE SRN TERMINALS.

&&

.MARINE...
A SOUTHERLY FLOW IS ANTICIPATED THROUGH TUESDAY WITH SOME
INCREASE ESPECIALLY DURING THE DAY TUESDAY. A FRONTAL ZONE HOWEVER
WILL BE DRAPED NEAR OUR NORTHERN ATLANTIC COASTAL WATERS THROUGH
TUESDAY THAT COULD AFFECT THE WINDS TO SOME EXTENT. THE INCREASE
THROUGH TUESDAY SHOULD BE ENOUGH TO BUILD SEAS TO 5 FEET ON THE
ATLANTIC COASTAL WATERS, AND WITH WARMER AIR OVER THE COOLER
WATERS WINDS SHOULD MOSTLY BE LESS THAN 25 KNOTS. HOWEVER THERE
SHOULD BE ENOUGH MIXING ESPECIALLY NEARSHORE ON TUESDAY TO PROMOTE
GUSTS TO ABOUT 25 KNOTS. THEREFORE, THE SMALL CRAFT ADVISORY
REMAINS IN EFFECT STARTING LATER TONIGHT. WE WILL HOLD OFF ON
ADDING AN ADVISORY FOR DELAWARE BAY ATTM AS THE SOUTHWEST WIND
DIRECTION SHOULD LIMIT ANY 25-KNOT GUSTS TO JUST NEARSHORE. SOME
THUNDERSTORMS TUESDAY ESPECIALLY LATE IN THE AFTERNOON COULD
PRODUCE LOCALLY STRONG WIND GUSTS.

OUTLOOK...
TUESDAY NIGHT...SCA EXTENDED THRU ALL OF TUESDAY NIGHT FOR THE
COASTAL WATERS WITH NELY WINDS GUSTING TO NEAR 25 KT AND SEAS NEAR
5 FT.

WEDNESDAY THROUGH FRIDAY...WINDS AND SEAS BELOW SCA THRESHOLDS.

&&

.FIRE WEATHER...
WE CONTINUE TO PROVIDE WEATHER SUPPORT FOR THE LARGE WILDFIRE
BURNING IN PORTIONS OF NORTHERN MONROE COUNTY THAT HAS SPREAD INTO
PIKE COUNTY.

HIGHER DEW POINTS OVERNIGHT AND TUESDAY ALONG WITH SHOWERS WILL
HELP WITH MOISTURE LEVELS AND HOPEFULLY PUT A DAMPER ON THE FIRE.
NEAR AND N OF I-80 COULD SEE ONE QUARTER INCH OVERNIGHT.

&&

.PHI WATCHES/WARNINGS/ADVISORIES...
PA...NONE.
NJ...NONE.
DE...NONE.
MD...NONE.
MARINE...SMALL CRAFT ADVISORY UNTIL 6 AM EDT WEDNESDAY FOR ANZ450>455.
