AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE MOUNT HOLLY NJ
557 AM EDT FRI APR 12 2013

.SYNOPSIS...
A STRONG WARM FRONT ACROSS THE DELMARVA WILL TRY TO MOVE NORTHWARD
TODAY AS LOW PRESSURE IN OHIO REDEVELOPS OVER SOUTHERN NEW JERSEY
THIS AFTERNOON. THAT LOW MOVES TO THE EAST OF NEW ENGLAND BY SATURDAY
MORNING. HIGH PRESSURE BUILDS ACROSS OUR AREA LATE SATURDAY INTO
SUNDAY, THEN SHIFTS OFFSHORE LATE SUNDAY AS A WARM FRONT LIFTS
THROUGH THE AREA MONDAY. THE NEXT COLD FRONT SLOWLY ARRIVES LATE
TUESDAY AND WEDNESDAY, AND IT MAY STALL NEARBY. THIS FRONT MAY
THEN LIFT BACK NORTHWARD AS A WARM FRONT WEDNESDAY NIGHT AND
THURSDAY AS AN AREA OF LOW PRESSURE TRACKS INTO THE GREAT LAKES.

&&

.NEAR TERM /UNTIL 6 PM THIS EVENING/...
AREAS OF VERY LIGHT DRIZZLE AND PATCHY FOG MOSTLY IN NJ AND DE AT
DAYBREAK WITH TEMPS AT HIGH POINT NJ 33F. NO ZR IN THE FCST FOR
THE HIGHEST POINT IN NJ AT THIS TIME.

OTRW SHOWERY RAINS ARE DEVELOPING NEWD INTO OUR FCST AREA PER THE
INSTABILITY BURST AS KI INCREASES CONSIDERABLY TOWARD SUNRISE WITH
THE DEEPENING MOISTURE FIELD.

TODAY...VERY LARGE BL TEMP GRADIENT N TO S ACROSS NJ-DE WITH A 30F
DEG SPREAD ANTICIPATED FM SUSSEX COUNTY NJ AT MIDDAY TO S DE AND
SE LOWER MD...TEMPS OF ROUGHLY NEAR 40F IN SUSSEX COUNTY NJ AND THE
POCONOS TO NEAR 75F IN S DELAWARE AND MARYLANDS E SHORE NEAR EASTON.

HEAVY SHOWERY RAINS IN THE STRONG LIFT OCCURS IN PA AND NJ TODAY
WITH A GOOD CHC FOR A BAND OF SCT TSTMS CROSSING DE/MD BETWEEN 16Z
AND 20Z WITH ISOLATED THUNDER FURTHER NORTH. ISOLATED SVR IS POSSIBLE
IN MD/DE EARLY THIS AFTN PER ML CAPE NOW ABOUT 800J.

HYDRO: NO FLOOD WATCH WAS ISSUED AND FFG SUGGESTS WE SHOULD BE ABLE
TO HANDLE 2 INCHES OF RAIN IN 6 HOURS. NEVERTHELESS...COULD SEE
THE NEED FOR A COUPLE OF AREA FLOOD WARNINGS FOR MINOR SMALL STREAM
FLOODING DURING MIDDAY OR THIS AFTN NEAR 195 CORRIDOR FROM CENTRAL
AND NORTHERN NJ INTO EAST CENTRAL OR SE PA OR EXTREME N NEW CASTLE
COUNTY DE. EXPECTING 1 TO POSSIBLY AS MUCH AS 2 INCHES OF RAIN
TODAY BASICALLY FROM NEAR PHL NORTHWARD....LESS THAN 1 INCH SE OF
OF THE I95 CORRIDOR.

CONVECTION: ML CAPE NEAR 800J AND THE WARM SECTOR S OF THE EVENTUAL
LOW TRACK FM VCNTY DCA TO NEAR KACY TODAY IS SUBJECT TO A BAND OF
TSTMS AND POSSIBLE ISOLATED SVR MIDDAY OR THIS AFTN WITH SCT TSTMS
PRECEDING THIS MORNING FM SE PA THRU THE DELMARVA.

DENSE FOG: POTENTIAL FOR DENSE FOG IN THE WARM FRONTAL ZONE THIS AFTN
NEAR WHERE THE SFC LOW TRACKS FROM MD E SHORE THOUGH DE...DE BAY INTO
CAPE MAY-WILDWOOD NJ.

TEMPS/DEWS/WIND ARE ALL 00Z/12 50M 50 BLENDED MAV/MET GUIDANCE THEN
BLENDED 50 50 WITH THE 2M TEMPS/WINDS OF THE 00Z/12 RGEM/NAM.

QPF IS HPC 00Z/12 VSN.

&&

.SHORT TERM /6 PM THIS EVENING THROUGH 6 AM SATURDAY/...
LEFTOVER DRIZZLE ENDS (POSSIBLY A BAND OF CONVECTIVE SHOWERS IN
COASTAL NJ THROUGH DE AT 00Z THIS EVENING) AND THEN SKIES SHOULD
AT LEAST PARTIALLY CLEAR LATE. 00Z/12 NCEP GUIDANCE BLENDED TEMPS.
PATCHY FOG TONIGHT.

&&

.LONG TERM /SATURDAY THROUGH THURSDAY/...
THE OVERALL SYNOPTIC SETUP IS COMPRISED OF AN UPPER-LEVEL TROUGH
FROM THE GREAT LAKES AND NORTHEAST SATURDAY INTO SUNDAY. THIS TROUGH
LOOKS TO BE REPLACED BY SOME RIDGING MONDAY. THE MAIN FORECAST
CHALLENGE IS THE TIMING OF THE NEXT COLD FRONT WHICH LOOKS TO
OCCUR SOMETIME DURING WEDNESDAY AND THURSDAY. THIS MAY INVOLVE
TWO DIFFERENT FRONTS, ONE THAT SETTLES IN LATE TUESDAY AND WEDNESDAY
AND STALLS BEFORE LIFTING NORTHWARD, THEN A SECOND MORE PRONOUNCED
FRONT APPROACHES LATER THURSDAY. THIS INVOLVES ENERGY THAT TRACKS TO
OUR WEST, WHICH HAS AN IMPACT ON THE TIMING OF THE FRONTAL
BOUNDARIES. WE GENERALLY USED A BLEND OF MODEL GUIDANCE AND
CONTINUITY SATURDAY THROUGH MONDAY, THEN BLENDED IN SOME OF THE NEW
WPC GUIDANCE WITH CONTINUITY THEREAFTER.

FOR SATURDAY AND SUNDAY...AN UPPER-LEVEL TROUGH WILL BE SETTLING
INTO THE NORTHEAST. THERE MAY BE A SECONDARY COOL FRONT OR SURFACE
TROUGH THAT SWINGS THROUGH LATE IN THE DAY SATURDAY, HOWEVER NO
PRECIPITATION IS EXPECTED WITH IT. OTHERWISE, SOME CAA OCCURS FOR
PART OF SATURDAY BEFORE A SECONDARY SURGE ARRIVES SATURDAY NIGHT.
THE WESTERLY FLOW THOUGH WILL HELP THE BOUNDARY LAYER RECOVER WITH
A DECENT AMOUNT OF SUNSHINE SATURDAY. A POTENTIAL FLY IN THE
OINTMENT THOUGH WOULD BE MORE CLOUDS DEVELOPING SATURDAY AS THE
SOUNDINGS SHOW STEEP LOW-LEVEL LAPSE RATES AND THE CONVECTIVE
TEMPERATURES BEING REACHED. THIS IN COMBINATION WITH AN INVERSION
AND SOME MOISTURE BELOW IT SUGGESTS DEVELOPING DAYTIME CUMULUS.
THEREFORE, WE INCREASED THE CLOUD COVER SOME. HIGH PRESSURE SLIDING
INTO THE UPPER OHIO VALLEY SATURDAY WILL MAINTAIN A TIGHTER PRESSURE
GRADIENT ACROSS OUR AREA, THEREFORE A WESTERLY BREEZE IS
ANTICIPATED. SOME STEEPER LOW-LEVEL LAPSE RATES IN COMBINATION WITH
A SHORT WAVE MAY PRODUCE A FEW SHOWERS ACROSS THE FAR NORTHWEST
ZONES, ALTHOUGH MOST OF THE GUIDANCE CONFINES THIS TO AREAS CLOSER
TO THE GREAT LAKES. A STRONGER SHORT WAVE SLIDES ACROSS THE NORTHERN
PART OF THE CWA SATURDAY NIGHT HOWEVER THE AIRMASS LOOKS DRY ENOUGH.
JUST SOME SLIGHT CHC POPS WERE KEPT ACROSS THE FAR NORTHWEST ZONES
SATURDAY INTO SATURDAY NIGHT, THEN DRY THROUGH SUNDAY. IF WE CAN
DROP THE WINDS OFF AND CLEAR THE SKY, THERE COULD BE PATCHY FROST
TOWARD SUNDAY MORNING IN SOME OUTLYING AREAS.

HIGH PRESSURE SHOULD THEN BE TRANSITIONING TO OUR EAST DURING
SUNDAY. THIS WILL RESULT IN LESS WIND WITH TIME AND ALSO HELP WITH
THE WAA DEVELOPING UP THE OHIO VALLEY AND TOWARD OUR CWA. THIS
SHOULD HELP ORGANIZE A WARM FRONT THAT ARRIVES FROM THE SOUTHWEST
LATE SUNDAY NIGHT. THE STRONGER WAA AND ISENTROPIC UPGLIDE REMAINS
TO OUR WEST, THEREFORE WE KEPT A DRY FORECAST GOING. THE FORECAST
SOUNDINGS SHOW LESS MOISTURE IN THE LOWER LEVELS, THEREFORE LESS
CLOUDS SHOULD BE AROUND ALTHOUGH SOME HIGH LEVEL CLOUDINESS MAY
ARRIVE.

FOR MONDAY AND TUESDAY...THE NEXT SYSTEM IS FORECAST TO TRACK
GENERALLY UP ACROSS THE WESTERN GREAT LAKES MONDAY THEN INTO CANADA
THROUGH TUESDAY. THIS PULLS A WARM FRONT TO OUR NORTH, THEN THE
ASSOCIATED COLD FRONT GRADUALLY ARRIVES AS WE GO THROUGH TUESDAY.
THIS BOUNDARY MAY SLOW ITS SOUTHEASTWARD PROGRESSION LATER TUESDAY
AS THE MAIN SYSTEM IS WELL TO OUR NORTH AND ADDITIONAL ENERGY
GATHERS ACROSS THE SOUTHERN PLAINS. WE CARRIED SLIGHT CHC OR LOW CHC
POPS FROM NORTHWEST TO SOUTHEAST MONDAY NIGHT AND TUESDAY WITH THE
ARRIVAL OF THIS FRONT. THERE IS ALSO THE POTENTIAL FOR A LEAD SHORT
WAVE TO SLIDE ACROSS THE GULF COAST AND SOUTHEASTERN STATES THROUGH
MONDAY. AS THIS OCCURS, OUR FLOW SHOULD BE SOUTHERLY. IT APPEARS
THAT THIS MOISTURE REMAINS TO OUR SOUTH AS HIGH PRESSURE SITUATED TO
OUR EAST TENDS TO DEFLECT IT. AS A RESULT, WE DID NOT RAISE THE
POPS. TEMPERATURES WERE MOSTLY CONTINUITY WITH A SMALL BLENDING IN
OF THE NEW WPC GUIDANCE.

FOR WEDNESDAY AND THURSDAY...AS ENERGY ORGANIZES ACROSS THE SOUTHERN
PLAINS, A NEW SURFACE LOW IS FORECAST TO TRACK UP THROUGH THE
TENNESSEE VALLEY AND INTO THE GREAT LAKES. AS THIS OCCURS,
INCREASING WAA TO ITS EAST WILL HELP SHARPEN THE THERMAL GRADIENT
ALONG THE FRONTAL BOUNDARY. THIS WILL CAUSE THE BOUNDARY TO BECOME A
WARM FRONT AS IT GRADUALLY SHIFTS NORTHWARD. IT IS UNCERTAIN ATTM IF
THIS SCENARIO PLAYS OUT LIKE THE CURRENT ONE, WHICH HAS A FRONT
NEARLY SOUTH OF OUR ENTIRE CWA AND THEREFORE LOCKS IN AN ONSHORE
FLOW. SINCE THE SURFACE HIGH IS FORECAST TO BE TO OUR EAST, WE MAY
END UP HAVING A SOUTHERLY FLOW WINNING OUT THIS TIME AROUND. WE
FAVORED WPC GUIDANCE AT THIS RANGE, WHICH SHOWS A WARM FRONT
LIFTING NORTHWARD. THERE COULD BE SHOWERS WITH THE WAA, HOWEVER THE
MAIN FORCING ATTM LOOKS TO BE CENTERED TO OUR WEST CLOSER TO THE
SURFACE LOW TRACK. THEREFORE, NO REAL CHANGES TO THE SLIGHT CHC AND
LOW CHC POPS WEDNESDAY INCREASING TO CHC POPS EVERYWHERE THURSDAY.

&&

.AVIATION /10Z FRIDAY THROUGH TUESDAY/...
THE FOLLOWING DISCUSSION IS FOR KPHL, KPNE, KTTN, KABE, KRDG, KILG,
KMIV, KACY AND SURROUNDING AREAS.

AT 10Z...GENERALLY IFR CONDS IN ST/FOG/VERY LIGHT DRIZZLE ENE WIND
G 15-25 KTS.

TODAY...IFR OR LIFR CONDS IN SHOWERY RAINS/PATCHY DRIZZLE AND FOG
WITH A POSSIBLE TSTM MIDDAY. RAIN WILL BE BRIEFLY HEAVY. THE WIND
MAY SHIFT SOUTH AT KMIV AND KACY FOR A TIME THIS AFTN BUT OTRW WINDS
TENDING TO BECOME NE G15-20 KT...DIMINISHING WIND SPEED LATE IN THE
DAY. SMALL POTENTIAL FOR ISO SVR STORM IN DE/E MD THIS AFTN.

TONIGHT...ANY LEFTOVER IFR CONDS IN DRIZZLE (BAND OF SHOWERS COASTAL
NJ INTO DE AT 00Z/13) DURING THE EVENING CLEARS FM WEST TO EAST
DURING THE NIGHT AS WINDS TURN NW. THERE IS A SMALL CHC OF PATCHY
IFR IN ST/FOG LINGERING OVERNIGHT IN A FEW SPOTS...ESPECIALLY
KABE-KMMU NORTHWARD. WINDS LIGHT N OR NW.

OUTLOOK...
SATURDAY AND SUNDAY...OVERALL VFR /A CHANCE OF LOCALIZED FOG EARLY
SATURDAY/. WEST TO NORTHWEST WINDS 10-15 KNOTS WITH GUSTS TO AROUND
20 KNOTS. THE HIGHEST WINDS FROM LATE MORNING THROUGH EARLY EVENING.
THE WINDS SHOULD DIMINISH SOME LATE SUNDAY.

MONDAY AND TUESDAY...MAINLY VFR. SOUTH-SOUTHEAST WINDS GENERALLY
10-15 KNOTS WITH GUSTS TO 20 KNOTS MONDAY, BECOMING SOUTHWEST
TUESDAY. THE HIGHEST WINDS FROM LATE MORNING THROUGH EARLY EVENING.
A LOW CHANCE OF SOME SHOWERS TUESDAY AS A COLD FRONT SLOWLY ARRIVES.

&&

.MARINE...
GALE ANZ450-451. SO FAR ONLY VERIFICATION IN ANZ450 SHOOK AND
44065. EXPECT STRONGEST GUSTS 7AM TO NOON TODAY...NEAR 40 KT.
OTRW SCA CONTINUES REMAINING ATLC WATERS FOR ENE WIND SHIFTING S
AND GUST 30 KT THIS AFTN. WINDS DIMINISHING TONIGHT AS THEY TURN
NW EVERYWHERE BUT LEFTOVER SEAS WILL BE AN SCA HAZARD ALL ATLANTIC
CW OF NJ AND DE OVERNIGHT.

SEAS WERE RAISED 2-3 FT ABOVE GUIDANCE VCNTY 44065 TODAY.

AS FOR DE BAY: SCA FOR THIS AFTN WHERE A BRIEF WARM SECTOR GUSTY
SSW WIND TO 30 KT IS EXPECTED AND ALSO A POSSIBLE SMW TSTM. TO GET
TO THE GUSTY SSW WINDS...DENSE FOG MAY BE A MARINER PROBLEM DURING
MIDDAY AS SFC DEWPOINTS NEAR 60 OVERRIDE THE COOLER SSTS OF DE
BAY. WINDS IN DE BAY SHIFT NW TONIGHT BUT PROB LESS THAN 23 KT.

OUTLOOK...
A WESTERLY FLOW IS EXPECTED SATURDAY INTO SUNDAY AS LOW PRESSURE
SLIDES TO OUR NORTHEAST. THE BOUNDARY LAYER SHOULD BE MILD ENOUGH TO
LIMIT THE VERTICAL MIXING SATURDAY, HOWEVER CAA FOR A TIME SATURDAY
NIGHT AND SOMEWHAT BETTER MIXING MAY ALLOW GUSTS TO REACH 25 KNOTS.
AS HIGH PRESSURE BUILDS ACROSS THE AREA LATER SATURDAY NIGHT INTO
SUNDAY, THE WINDS ARE ANTICIPATED TO DIMINISH. A SOUTHERLY FLOW THEN
DEVELOPS SUNDAY NIGHT WHICH CONTINUES MONDAY AND TUESDAY. THE WINDS
COULD GET CLOSE TO SMALL CRAFT ADVISORY CRITERIA, AND SEAS BUILD
TO 4-5 FEET ON THE OCEAN DUE TO THE SOUTHERLY FLOW.
