What happened

The episode as NWS PHI wrote it up.

A deep low pressure system tracked across the Lower Great Lakes northeastward into the St. Lawrence Valley from the evening of the 20th into the daytime of the 21st. Its associated strong cold front swept eastward through the Mid Atlantic region and across New Jersey during the early morning of the 21st. In addition, a secondary area of low pressure formed along the frontal boundary, west of Delaware Bay, and deepened rapidly. The approaching cold front and the deepening secondary low pressure produced a strong southeasterly flow over the region that resulted in peak wind gusts ranging from 46 mph to 64 mph across the state. About 35,000 homes and businesses lost power because of downed trees, tree limbs and wires. In addition, the significant southeast flow allowed water to pile up along the New Jersey shore and into Delaware Bay, producing minor to moderate coastal flooding at the time of high tide on the morning of the 21st. Tidal flooding increased further along tidal sections of the Delaware River as major flooding occurred. Moderate to heavy rain fell across the state, with storm totals ranging between 1 to 3 inches. This rain resulted in some mainly minor flooding of smaller streams and creeks in southern New Jersey.

The strong onshore flow contributed to higher high tides with minor to moderate tidal flooding occurring along the southern New Jersey oceanfront and in Barnegat Bay. In Ocean County, tidal flooding was reported on the barrier island section of Brick Township. In Toms River Township, tidal flooding was reported in the Green Island and Silverton sections of the township on Barnegat Bay. High tide at Atlantic City Reached 6.71 feet above mean lower low water. Minor tidal flooding starts at 6.0 feet above mean lower low water. High tide at Cape May reached 7.82 feet above mean lower low water. Moderate tidal flooding starts at 7.7 feet above mean lower low water.

The southeasterly flow pushed water up the Delaware Bay and into the tidal portions of the Delaware River, causing major tidal flooding to occur. Major tidal flooding occurred in both Philadelphia and Reedy Point. High tide at Reedy Point reached 9.2 feet above mean lower low water. Major tidal flooding starts at 9.2 feet above mean lower low water. High tide in Philadelphia reached 10.35 feet above mean lower low water. This was the third highest tide on record. Major tidal flooding starts at 10.2 feet above mean lower low water. The high tide reached 11.13 feet above mean lower low water in Burlington City (Burlington). There are no established levels of tidal flooding at this site.

In Cumberland County, tidal flooding along the bay and the Maurice River caused water to spill over the causeway. In addition, a dike was broken in Maurice River Township near Matts Landing Road. Flooding was reported along Route 47. In Maurice River Township, Main Street in Dorchester was covered in 4 to 5 feet of water and Beaver Dam Road and County Route 553 were covered with 2 feet of water. In Commercial Township, homes in Bivalve and Port Norris were surrounded by water. Cove Road was flooded and closed. In Downe Township, the tides and waves knocked down bulkheads and forced the displacement of two families. One thousand feet of unpaved road was also reported to be washed away in Gandys Beach.

In Salem County, tidal flooding closed Hook Road in Pennsville Township (along the Salem Canal), Sinnickson Landing Road (along the Salem River) in Elsinboro Township, New Jersey State Route 45 in Salem (along the Salem River) and County Route 540 in Mannington Township (along the Salem Creek). Tidal flooding also affected the Penns Grove Carneys Point Library again. Tidal flooding off of Oldmans Creek flooded Woodstown-Pedericktown Road. The tidal surge combined with freshwater runoff to cause flooding of Acton Station Road in Mannington Township and Alloway-Quinton Road in Alloway and Quinton Townships.

In Gloucester County, several roadways were closed due to tidal flooding. In Logan Township, High Hill Road off the Raccoon Creek and Center Square Road off of Oldmans Creek were flooded. In West Deptford Township, Crown Point Road was closed between the Mid Atlantic Parkway and Mantua Grove Road off of the Main Ditch. Tidal flooding was reported along the Big Timber Creek near Westville. Water was reported to have entered at least one home in the area. Parts of Route 130 and Route 47 were closed due to flooding in the area.

In Camden County, a combination of tidal and freshwater flooding caused lanes on the Admiral Wilson Boulevard to be blocked as far east as New Jersey State Route 38. Flooding was also reported at the Brooklawn Circle and U.S. Route 130 in Gloucester City (Off of the South Branch of the Big Timber Creek), where the highway was closed in both directions. In Burlington County, home evacuations were performed due to tidal flooding in Burlington City.

In Southern New Jersey, wind related power outages were concentrated in Cumberland and Salem Counties. The Gloucester County College and Institute of Technology canceled classes on the 21st because of power outages. A downed pole closed a section of New Jersey State Route 47 in Gloucester County. In central New Jersey, power outages were concentrated in the Toms River area. In Northern New Jersey, approximately 27,000 homes and businesses lost power. Some of the more concentrated outages were in Pequannock and East Hanover in Morris County. In Hunterdon County, downed trees, poles and wires closed roadways in East and West Amwell Townships. Peak wind gusts included 64 mph in Sandy Hook (Monmouth County), 62 mph in Burlington (Burlington County), 59 mph in Eatontown (Monmouth County), 58 mph in Westville (Gloucester County), 57 mph in Sea Girt (Monmouth County) and at North Beach (Ocean County), 56 mph at the Millville Airport (Cumberland County), 55 mph in Tuckerton (Ocean County), 54 mph in Seaside Heights (Ocean County) and in Mullica Township (Atlantic County), 52 mph in Ocean City (Cape May County) and at McGuire Air Force Base (Burlington County) and also at the intersection of Interstate 78 and County Road 525 (Somerset County), 51 mph at the Atlantic City International Airport (Atlantic County), 50 mph in Hamilton (Mercer County) and also at the intersection of I-295 and Route 140 (Salem County), 49 mph in Upper Deerfield Township (Cumberland County), 48 mph at Cape May Harbor (Cape May County) and at the Belmar-Farmingdale Airport (Monmouth County), 47 mph at the Trenton Airport (Mercer County) and in New Brunswick (Middlesex County) and also in Harvey Cedars (Ocean County), and 46 mph in Pittstown (Hunterdon County). Strong winds occurred throughout central to southern parts of the state, beginning a few hours prior to daybreak and ending soon after sunrise on the 21st. A few areas also recorded high winds during this timeframe. Winds decreased by mid-morning following the passage of the surface cold front.

Area forecast discussion, Dec 20, 9:19 PM EST, 2 hours 41 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE MOUNT HOLLY NJ
919 PM EST THU DEC 20 2012

.SYNOPSIS...
A POTENT AREA OF LOW PRESSURE WILL TRACK ACROSS THE GREAT LAKES AND
NORTHEAST TONIGHT AND FRIDAY, THEN ACROSS EASTERN CANADA DURING THE
WEEKEND. ITS ASSOCIATED STRONG COLD FRONT WILL SWEEP ACROSS OUR
REGION EARLY FRIDAY MORNING. A WEAK AREA OF HIGH PRESSURE THEN
BUILDS DOWN INTO OUR REGION LATE SUNDAY AND MONDAY. A WEAK LOW
PRESSURE SYSTEM MAY AFFECT OUR AREA MONDAY NIGHT INTO TUESDAY, WITH
THE POTENTIAL FOR A MUCH STRONGER STORM SET TO ARRIVE ON THURSDAY.

&&

.NEAR TERM /UNTIL 6 AM FRIDAY MORNING/...
STARTING IN THE POCONOS, WE ARE PLANNING ON LETTING THE ADVY
EXPIRE AT 11 PM. THE DRY AIR ALOFT HAS EVAP COOLED AND THE
FREEZING RAIN IN THE HIGHER TERRAIN HAS CHANGED TO SNOW. THE
NUMBER OF MESONET SITES BELOW FREEZING WHICH ONCE WAS AROUND 20 IS
DOWN TO 6. HRRR AND LATEST WRF-NMMB HAS EVERYONE ABOVE FREEZING BY
03Z. SOME SLIPPERY SPOTS WERE REPORTED IN THE HIGHER TERRAIN OF
MONROE COUNTY AND AROUND A QUARTER INCH OF SNOW IN PLACES.

NOW FOR THE OTHER WEATHER HAZARD, THE WIND. NOT AN EASY DECISION
BECAUSE THE SOUNDINGS ARE NEARLY ISOTHERMAL WITH POOR LAPSE RATES.
THE 00Z SOUNDINGS SUPPORTED A COMP BETWEEN THE WRF-NMMB AND GFS
FCST SPEEDS. SINCE THEN THE VWP LOOK OK AT KAKQ AND KLWX FOR THE
NEW WRF-NMMB 925MB WINDS, BUT THE MODEL IS RUNNING AROUND 5 TO
10 KTS TOO HOT AT 850MB. SO FAR THE MIXING OF STRONGER WINDS IN
THE CAROLINAS HAS BEEN SPORADIC. SO WHAT WE CAN GATHER THERE HAVE
NOT BEEN UPSIDE SURPRISES YET. THE OVERALL WIND FIELDS ARE
FORECAST THOUGH TO INTENSIFY FURTHER AS TIME GOES ON TONIGHT AND
THE MOMENTUM TRANSFER WINDS ON OCCASION ARE MIXING ADVY LEVEL WIND
GUSTS DOWN. THE MESOSCALE MODELS AND WE DONT KNOW IF THEY ARE THIS
GOOD ARE NOT FORECASTING A SINGLE NCFRB TOWARD MORNING. AFTER
COORD WITH OKX AND LOOKING AT THE 12/1/10 ANALOG THEY FOUND (WHICH
WAS AN ADVY TYPE EVENT CENTERED MAINLY IN THE ERN PART OF OUR
CWA), WE DECIDED TO ISSUE A WIND ADVY THAT COINCIDES CLOSEST WITH
THE 70KT OR GREATER ISOTACH ON THE LATEST WRF-NMMB. WE INCLUDED
ALL OF DELAWARE BAY BECAUSE OF THE SE FLOW. IF A NCFRB DOES FORM
NEAR THE JET MAX, THE ADVY MAY NEED TO BE UPGRADED OR EXPANDED.
RIGHT NOW CONFIDENCE IS TOO LOW TO ISSUE.

THE REST OF THE FCST WAS KEPT PRETTY MUCH AS IS, MOST OF THE
HEAVIEST PCPN IS EXPECTED TO FALL AFTER MIDNIGHT AND END RATHER
QUICKLY WITH THE CFP AROUND 12Z.

OTHER THAN SOME NUISANCE FLOODING, NO HYDRO ISSUES ARE EXPECTED.

&&

.SHORT TERM /6 AM FRIDAY MORNING THROUGH 6 PM FRIDAY/...
A THREAT OF RAIN SHOULD STILL EXIST FOR THE NORTHERN ZONES EARLY
TOMORROW MORNING. THEN WHEN THE UPPER LOW AND COLD POOL ALOFT MOVES
CLOSER, A SHOWER ANYWHERE CAN'T BE RULED OUT. TEMP PROFILES
SUGGEST SNOW SHOWERS FAR NORTH AND WEST.

TEMPS WILL HOLD STEADY OR FALL THROUGH THE 40S (30S NORTH AND WEST)
TOMORROW WITH WINDS GUSTING TO 30 OR 40 MPH.

LITTLE TO NO ACCUMULATION IS EXPECTED WHERE THE FLAKES FLY.

&&

.LONG TERM /FRIDAY NIGHT THROUGH THURSDAY/...
A RATHER ACTIVE PATTERN LOOKS TO CONTINUE. THE OVERALL SYNOPTIC FLOW
IS COMPRISED OF A DEEP TROUGH OVER THE EAST FRIDAY NIGHT AND
SATURDAY, THEN ADDITIONAL ENERGY PUSHING INTO THE WEST ALLOWS
DOWNSTREAM RIDGING TO KICK THE TROUGH INTO CANADA WHERE IT TENDS TO
BECOME ELONGATED WEST TO EAST. A PIECE OF ENERGY ROTATING AROUND
THIS MAY ALLOW FOR A SHORT WAVE TROUGH TO SLIDE ACROSS THE GREAT
LAKES INTO THE NORTHEAST AROUND TUESDAY. A MUCH MORE PRONOUNCED
UPPER-LEVEL TROUGH THEN LOOKS TO EJECT OUT OF THE FOUR CORNERS
REGION TUESDAY NIGHT INTO WEDNESDAY. THIS FEATURE ALONG WITH A
DEEPENING SURFACE LOW IS THEN FORECAST TO MOVE THROUGH THE EAST NEXT
THURSDAY. OVERALL, THE MODEL GUIDANCE CONTINUES TO SHOW VARIABILITY
WITH TIMING AND SPACING OF EMBEDDED INDIVIDUAL FEATURES HOWEVER
CONTINUED SUPPORT FOR AN ACTIVE PATTERN. THE THERMAL GRADIENTS AND
AMPLITUDE OF THE PATTERN MAY BE PLAYING A ROLE WITH THE MODEL
VARIABILITY. IT APPEARS THERE IS AN INCREASING SIGNAL FOR AN EAST
COAST STORM DURING ABOUT THE SECOND HALF OF NEXT WEEK. OF COURSE
THIS FAR OUT, THE DETAILS ARE MUCH LESS CERTAIN AND THEREFORE MUCH
LOWER CONFIDENCE IN THE FORECAST BEYOND TUESDAY ESPECIALLY.

FOR FRIDAY NIGHT AND SATURDAY...AN INTENSE STORM IS FORECAST TO BE
IN THE SOUTHEAST CANADA AND NEW ENGLAND AREAS DURING THIS TIME
FRAME. IT WILL BE DRIVEN BY A SHARP UPPER-LEVEL TROUGH WITH A SHOT
OF MUCH COLDER AIR ALONG WITH IT. A RATHER DEEP CYCLONIC FLOW REGIME
WILL BE OCCURRING WITH THE POTENTIAL FOR SOME WRAPAROUND SNOW
SHOWERS, AND THE LAKE EFFECT SNOW MACHINE SHOULD BE IN HIGH GEAR. AS
THE CAA CONTINUES, SHORT WAVE ENERGY ROTATING AROUND THE PARENT
UPPER-LEVEL TROUGH SHOULD HELP TO MAINTAIN SOME SNOW SHOWERS INTO
OUR NORTHWEST ZONES. SOME OF THE MODEL GUIDANCE SHOWING SIGNS OF
CHANNELIZED VORTICITY ORIENTATED NORTHWEST TO SOUTHEAST. IF DEEP
ENOUGH MOISTURE CAN BE MAINTAINED AND ENOUGH LIFT/INSTABILITY CAN
OCCUR WITHIN THE NORTHWEST FLOW, SOME LOCALIZED SNOW SQUALLS MAY
OCCUR ACROSS NORTHEASTERN PENNSYLVANIA AND NORTHWESTERN NEW JERSEY.

WE WOULD LIKE TO SEE BETTER ORGANIZATION OF THE CHANNELIZED
VORTICITY TO INCREASE CONFIDENCE REGARDING LAKE EFFECT STREAMERS
REMAINING INTACT THIS FAR SOUTHEAST FROM THE LAKES. FOR NOW, WE
CARRIED LOW LIKELY POPS ACROSS THE POCONOS AND TOWARD FAR NORTHWEST
NEW JERSEY, THEN POPS TAPER WITH A SOUTHEASTWARD EXTENT. BEYOND THE
SLIGHT CHC POPS, WE CARRIED SCATTERED FLURRIES DOWN TO THE
INTERSTATE 95 CORRIDOR. SOME PLACES PARTICULARLY IN THE POCONOS
COULD PICK UP AN INCH OR TWO OF SNOW. FARTHER SOUTHEAST, WHILE A FEW
HEAVIER SNOW SHOWERS MAY BE ABLE TO OCCUR, THE DOWNSLOPING FLOW MAY
PROVIDE ENOUGH EXTRA DRYING TO ERODE THESE. THIS IS OF LOWER
CONFIDENCE THEREFORE DID NOT BRING THE SNOW SHOWER MENTION EVEN
FARTHER SOUTHEAST AND WENT WITH FLURRIES.

ANOTHER FORECAST CONCERN IS THE STRONG WIND POTENTIAL. A RATHER
TIGHT PRESSURE GRADIENT IS FORECAST TO REMAIN ACROSS OUR ENTIRE. THE
CAA COMBINED WITH THE TIGHT PRESSURE GRADIENT SHOULD KEEP THE SURFACE
WINDS GOING FRIDAY NIGHT DESPITE LESSENING VERTICAL MIXING AT TIMES.
THE VERTICAL MIXING IS MUCH MORE PRONOUNCED SATURDAY AS THE AIRMASS
IS CHILLY, THE LOW-LEVEL LAPSE RATES STEEPEN SOME MORE AND THERE IS
PLENTY OF WIND NOT TO FAR ABOVE THE SURFACE. THE FORECAST SOUNDINGS
GET CLOSE TO 40 KNOTS POTENTIALLY MIXING DOWN TO THE SURFACE,
ALTHOUGH THE GFS IS MORE ROBUST WITH THIS AS IT SUGGESTS NEARLY
50 KNOTS MIXING DOWN TO THE SURFACE. THE 925 MB WINDS ARE NOT AS
STRONG ON THE ECMWF WITH AROUND 40 KNOTS FORECAST SATURDAY
ESPECIALLY ACROSS THE SOUTHERN HALF OF OUR CWA. WE THOUGHT ABOUT
GOING WITH A HIGH WIND WATCH WITH THE GREATER CHC ACROSS ABOUT THE
SOUTHERN HALF OF THE CWA, HOWEVER THIS IS NEARLY TWO DAYS OUT. IT
MAY END UP BEING A WIND ADVISORY TYPE EVENT THEREFORE WE DECIDED TO
HOLD OFF ON ANY HEADLINES ATTM. WE HOWEVER WILL CONTINUE A
MENTION IN THE HAZARDOUS WEATHER OUTLOOK. WE INCREASED THE WINDS
SOME /ESPECIALLY GUSTS/ FOR SATURDAY FROM CONTINUITY WITH GUSTS
GENERALLY IN THE 40-45 MPH RANGE. AS FOR HIGH AND LOW TEMPERATURES,
WE GENERALLY TOOK AN EVEN BLEND OF THE NAM/GFS MOS.

FOR SUNDAY AND MONDAY /CHRISTMAS EVE/...THE POTENT STORM IS FORECAST
TO MOVE UP THROUGH THE CANADIAN MARITIMES, HOWEVER A TIGHTENED
PRESSURE GRADIENT GENERALLY REMAINS IN PLACE. THE OVERALL FLOW
THOUGH WILL BE LESSENING, HOWEVER VERTICAL MIXING WILL PROVIDE
ENOUGH FOR A BRISK DAY ON SUNDAY. IT APPEARS THAT WITHIN THE
NORTHWESTERLY FLOW, A SHORT WAVE ROTATING AROUND THE PARENT STORM
MAY TOSS A SURFACE TROUGH OR COLD FRONT TOWARD OUR REGION. THE LAKE
EFFECT SNOW MACHINE SHOULD BE WINDING DOWN SUNDAY AS THE CAA WANES
SOME AND THE LOW-LEVEL FLOW MAY TURN MORE WESTERLY.

A SHORT WAVE TRAVERSING THE NORTHERN TIER CHRISTMAS EVE MAY ALLOW
FOR A SURFACE LOW REFLECTION TO RACE OUT AHEAD OF THE DEEPENING
TROUGH IN THE WEST. SOME MOISTURE RETURN AHEAD OF IT ALONG WITH WAA,
MAY RESULT IN AN AREA OF OVERRUNNING PRECIPITATION. THERE IS A
QUESTION REGARDING HOW DRY THE AIRMASS IS OVER OUR AREA AND THE
STRENGTH OF THE OVERALL LIFT. A LIGHT INTENSITY OF THE PRECIPITATION
MAY PLAY MORE OF A ROLE, WITH EVEN DEPENDING ON HOW THE BOUNDARY
LAYER BEHAVES. FOR NOW WE WILL FAVOR SLIGHT CHC POPS FOR A WEAK
OVERRUNNING POTENTIAL AND GO RAIN AND/OR SNOW.

FOR TUESDAY...THE AFOREMENTIONED FRONT RUNNER WEAKER SURFACE WAVE
SHOULD SCOOT OUT TO SEA EARLY TUESDAY AS THE SHORT WAVE TROUGH MAY
END UP DAMPENING OUT SOME. WHILE THERE COULD BE SOME RESIDUAL LIGHT
PRECIPITATION AROUND TO START TUESDAY, WE SIMPLY FAVORED SLIGHT CHC
POPS IN THE MORNING GIVEN LOWER CONFIDENCE ON TIMING AND OF ANY MORE
ORGANIZED LIFT.

FOR WEDNESDAY AND THURSDAY...THE PATTERN ONCE AGAIN STARTS TO REALLY
RAMP UP WEDNESDAY AS ENERGY FROM THE FOUR CORNERS REGION SLIDES
ACROSS THE PLAINS AND THEN THE TENNESSEE VALLEY. THERE IS ANOTHER
SYSTEM UP IN THE CANADIAN MARITIMES OVERALL, WHICH WOULD TEND TO
LEAD TO BLOCKING. THIS DEVELOPING PATTERN IS LOOKING MORE CONDUCIVE
FOR A COASTAL STORM TO OCCUR. IN THIS UPCOMING POTENTIAL, THE
INITIAL SURFACE LOW MAY TRACK UP THE OHIO VALLEY BUT THEN WEAKEN.
HIGH PRESSURE POSITIONED OVER EASTERN CANADA, IF IT CAN BE
MAINTAINED, MAY HELP TO WEDGE A COLDER LOW-LEVEL AIRMASS SOUTHWARD
ACROSS AT LEAST PORTIONS OF OUR AREA. THIS COLD AIR DAMMING SCENARIO
WOULD OPEN THE DOOR FOR SURFACE LOW REDEVELOPMENT NEAR THE VIRGINIA
COAST AS THE BAROCLINICITY TIGHTENS UP DUE TO THE THERMAL GRADIENT
INCREASING. THIS WOULD PROBABLY ALLOW FOR SOME WARMING ESPECIALLY
ALOFT UNTIL THE MAIN STORM GETS GOING OFF OR ALONG THE COAST.
THEREFORE, CLOUDS INCREASE WEDNESDAY AND WE WENT WITH 40-50 POPS FOR
NOW AS THE POTENTIAL IS THERE FORE A DECENT STORM. WE HELD OFF ON
GOING WITH LIKELY POPS DUE TO ENOUGH MODEL UNCERTAINTY REGARDING
TIMING AND ESPECIALLY THE DETAILS. WE WENT WITH RAIN AND/OR SNOW FOR
THE PRECIPITATION TYPE AS ANY OTHER FROZEN/FREEZING PRECIPITATION IS
MORE DEPENDENT ON THE ACTUAL THERMAL STRUCTURES.

&&

.AVIATION /02Z FRIDAY THROUGH TUESDAY/...
THE FOLLOWING DISCUSSION IS FOR KPHL, KPNE, KTTN, KABE, KRDG, KILG,
KMIV, KACY AND SURROUNDING AREAS.

THE 00Z TAFS CONTINUED THE DECENT INTO IFR AND LIFR AS THE
HEAVIER RAIN MOVES IN TONIGHT WITH THE LOWEST CONDITIONS AFTER
MIDNIGHT. WE ALSO CONTINUED THE MENTION OF LLWS. THE GRADIENT EAST
TO SOUTHEAST WIND ITSELF WILL ALSO INCREASE AND GUSTS TO AROUND 40
KTS ARE POSSIBLE AT TERMINALS AND AIRPORTS CLOSER TO THE OCEAN IN
NEW JERSEY AND DELAWARE.

THE COLD FRONT IS EXPECTED TO MOVE THROUGH FROM SOUTHWEST TO
NORTHEAST ACROSS OUR CWA WITH PASSAGE TIME PLUS OR MINUS OF 12Z
BY A COUPLE OF HOURS. RAPID IMPROVEMENT TO MVFR IF NOT VFR
CONDITIONS IS THEN FORECAST. WINDS THOUGH WILL REMAIN BLUSTERY,
BUT THIS TIME FROM THE WEST. CIGS SHOULD IMPROVE TO VFR BY LATE IN
THE MORNING. WINDS WILL REMAIN BRISK THROUGH THE DAY. PEAK GUSTS
OF AROUND 30 KTS ARE LIKELY.

OUTLOOK...
FRIDAY NIGHT AND SATURDAY...MAINLY VFR. WEST-NORTHWEST WINDS
SUSTAINED 15-25 KNOTS WITH GUSTS TO AROUND 35 KNOTS. THE STRONGER
WINDS SHOULD OCCUR DURING THE DAY SATURDAY. THERE COULD BE SOME
SUB-VFR CONDITIONS IN LOCAL/BRIEF SNOW SHOWERS ESPECIALLY FROM THE
KABE AND KRDG TERMINALS NORTH AND WEST.

SUNDAY...VFR WITH NORTHWESTERLY WINDS MAINLY 10-20 KNOTS.

MONDAY AND TUESDAY...VFR MONDAY ALTHOUGH CLOUDS SHOULD INCREASE AND
LOWER SOME. A WEAKER SYSTEM MAY MOVE THROUGH MONDAY NIGHT INTO
TUESDAY WITH THE CHANCE OF SOME LIGHT PRECIPITATION. LIGHT WINDS
MONDAY BECOME NORTHERLY NEAR 10 KNOTS TUESDAY.

&&

.MARINE...
A STRONG COLD FRONT WILL TRACK ACROSS OUR REGION EARLY TOMORROW
MORNING. GALES REMAIN IN PLACE FROM 700 PM TONIGHT, THROUGH THE
SHORT TERM PERIOD, AND INTO THE OUTLOOK PERIOD. SOUTHEAST WINDS
TONIGHT WILL BECOME SOUTHWEST TOMORROW. SEAS WILL RESPOND AND COULD
REACH DOUBLE DIGITS. RAIN OVERNIGHT TONIGHT WILL BECOME MOE SHOWERY
TOMORROW.

OUTLOOK...
A POTENT STORM IS FORECAST TO BE TO OUR NORTH FRIDAY NIGHT THROUGH
SATURDAY BEFORE SHIFTING INTO THE CANADIAN MARITIMES DURING THE
WEEKEND. A TIGHT PRESSURE GRADIENT IN COMBINATION WITH CAA WILL
ALLOW FOR STEEPER LOW-LEVEL LAPSE RATES AND EFFICIENT VERTICAL
MIXING. THE GFS 925 MB WINDS ARE MUCH STRONGER COMPARED TO THE NAM
AND ECMWF, HOWEVER ALL POINT TO GALE FORCE WINDS OCCURRING. THE GFS
WOULD SUGGEST A CHC FOR A PERIOD OF STORM FORCE GUSTS. WE ARE NOT
ALL THAT CONFIDENT REGARDING STORMS, THEREFORE WE WILL CONTINUE WITH
THE GALE WARNING THROUGH THE DAY SATURDAY. THE WINDS SHOULD START
DIMINISHING SATURDAY NIGHT, THEREFORE WE DECIDED NOT TO EXTEND THE
GALE WARNING ATTM. THERE SHOULD BE A PERIOD OF SMALL CRAFT ADVISORY
CONDITIONS FOLLOWING THE GALES INTO ABOUT SUNDAY. A WEAK SYSTEM MAY
THEN MOVE THROUGH MONDAY NIGHT INTO TUESDAY, HOWEVER THE WINDS AND
SEAS ARE ANTICIPATED TO BE BELOW ADVISORY CRITERIA.

&&

.TIDES/COASTAL FLOODING...
A COASTAL FLOOD ADVISORY HAS BEEN ISSUED FOR FRIDAY MORNING'S HIGH
TIDE ALONG ALL OUR COASTAL SECTIONS, INCLUDING THE TIDAL PORTION OF
THE DELAWARE RIVER, EXCLUDING CHESAPEAKE BAY. STRENGTHENING
SOUTHEAST FLOW WILL ALLOW WATER TO PILE UP ALONG THE COASTAL
SECTIONS WHERE CURRENT DEPARTURES ARE RUNNING AROUND +1.5 FEET ABOVE
ASTRONOMICAL...THIS IS WITHOUT A STRONGER SOUTHEASTERLY FETCH THAT
IS EXPECTED TO OCCUR TONIGHT.

SOME OF OUR NUMERICAL GUIDANCE IS SUGGESTING THE UPPER DELAWARE BAY
AND LOWER DELAWARE RIVER COULD SEE SPOTTY LOW-END MODERATE COASTAL
FLOODING. THIS WILL HAVE TO BE CLOSELY WATCHED AND RE-EVALUATED
AFTER THIS EVENING'S HIGH TIDE...ANY ADDED FRESH WATER COULD
EXACERBATE THE ISSUE. WINDS ARE EXPECTED TO SHIFT TO THE WEST BY
LATE FRIDAY MORNING AND WILL HELP TO PUSH THE WATER OUT.

AS FOR THE CHESAPEAKE BAY, CURRENT DEPARTURES ARE A RUNNING LESS
THEN +1.0 FOOT. WITH THE HIGHER OF THE TWO HIGH TIDES OCCURRING LATE
FRIDAY MORNING INTO THE EARLY AFTERNOON HOURS THERE IS STILL TIME TO
ASSESS THE POTENTIAL FOR ANY COASTAL FLOODING. BASED ON OUR NEW
ADVISORY CRITERIA OF 3.8 FEET BOTH CAMBRIDGE AND TOLCHESTER BEACH
WOULD NEED AROUND A +2.5 FOOT DEPARTURE TO REACH THE MINOR
THRESHOLD.
