What happened

The episode as NWS PHI wrote it up.

A potent pair of storms moved through the Mid Atlantic and Northeast during the 7th and into the 8th. One potent storm moved across the eastern Great Lakes region during the evening of the 7th, while a secondary potent storm developed along a front off the New Jersey coast. Both of these storms combined into one large and intense storm early on the 8th across the Canadian Maritimes. Behind these storms, much colder air flowed across the region, and this combined with a tightened pressure gradient, which produced strong offshore winds. This caused blow-out tides to occur during the late evening hours of the 8th and the early morning hours of the 9th.

The water level at the Reedy Point tidal gage dropped to 1.82 feet below mean lower low water at 2:42 AM EST on the 9th then bottomed out at 2.39 feet below mean lower low water at 4:00 AM EST on the 9th. The water level at the Delaware City tidal gage dropped to 1.84 feet below mean lower low water at 2:48 AM EST on the 9th then bottomed out at 2.50 feet below mean lower low water at 4:12 AM EST on the 9th. Meanwhile, further southeast, the water level at the Lewes tidal gage dropped to 1.88 feet below mean lower low water at 10:48 PM EST on the 8th and bottomed out at 2.31 feet below mean lower low water between 11:36 PM EST and 11:42 PM EST on the 8th. Blow-out tides begin at 1.80 feet below mean lower low water.

Area forecast discussion, Jan 8, 8:50 PM EST, 1 hour 40 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE MOUNT HOLLY NJ
850 PM EST THU JAN 8 2009

.SYNOPSIS...
STRONG LOW PRESSURE WELL TO THE NORTHEAST AND A RIDGE OF HIGH
PRESSURE OVER THE SOUTH WILL KEEP COLD BUT DRY WEATHER ACROSS THE
AREA OVERNIGHT THROUGH FRIDAY. ONCE THE HIGH MOVES AWAY FRIDAY NIGHT
A LOW PRESSURE SYSTEM WILL MOVE UP THE OHIO VALLEY AND THEN ACROSS
OUR AREA AROUND SATURDAY NIGHT. HIGH PRESSURE WILL BRIEFLY BUILD
INTO THE AREA BEHIND THE DEPARTING LOW. THEN A VERY STRONG COLD
FRONT IS EXPECTED TO MOVE THROUGH THE REGION ON TUESDAY WITH AN
ARCTIC AIR MASS ARRIVING IN ITS WAKE.

&&

.NEAR TERM /UNTIL 6 AM FRIDAY MORNING/...
ZONES AND GRIDS UPDATED TO REMOVE EVENING WORDING. MIN TEMPS LOOK
REASONABLE. THERE IS STILL CYCLONIC FLOW ALOFT ALONG WITH THOSE
CHANNELIZED VORT MAXES. WE EXTENDED THE MENTION OF FLURRIES A BIT
MORE TO THE SE BASED ON CUR OBS. THERE ARE ALSO SOME RADAR RETURNS
TO OUR SW, BUT ATTM NONE OF THEM ARE REACHING THE GROUND. STILL NOT
OUT OF A QUESTION THAT A FLURRY OR TWO MIGHT FLY ACROSS SOUTHERN
PARTS OF OUR CWA.

WE DID A 12 HOUR FORECAST VS RAOB INITIALIZATION AT 00Z TO SEE WHICH
MODEL IS HANDLING THE PACIFIC NW THE BEST. THE NAM 12HR FCST WAS THE
WORST OF THE FOUR (UKMET, GFS, NAM OR WRF-NMM AND ECMWF) WITH BOTH
SHORT WAVE TROFS. THE SHORT WAVE TROF IN ALBERTA CANADA THAT THE
ECMWF HAS BEEN SHARPER FOR SEVERAL RUNS IS HANDLED PRETTY WELL AS A
12 HOUR FORECAST BY BOTH OF THEM, A SLIGHT NOD TO THE ECMWF. THE
BIGGER DISCREPANCY IS WITH THE SECOND SHORT WAVE WHICH GOES THROUGH
THE ROCKIES AND PHASES WITH THE FORMER IN THE PLAINS. IT IS
SHARPER OR AT THE LEAST SLOWER THAN ANY OF THE MODELS HAVE WITH THE
ECMWF THE CLOSEST. 500MB HEIGHTS ARE LOWER THAN ANY OF THE MODELS
HAVE FOR THE RAOB SITES ALONG THE IMMEDIATE WEST COAST FROM SEATTLE
TO OAKLAND BY ABOUT 10 TO 20 METERS. AS FAR AS NEARBY 850MB TEMPS
GO, THE MODELS ARE ALL PRETTY CLOSE, THE NAM/WRF-NMM ABOUT 1-2C TOO
COLD WITH THE GFS AND ECMWF SPOT ON IN MANY PLACES.

THE 00Z/FRI NAM INITIALIZATION DID NOT CATCH THE LOWER HEIGHTS ALONG
THE WEST COAST.

&&

.SHORT TERM /6 AM FRIDAY MORNING THROUGH SATURDAY NIGHT/...
FRIDAY AND FRIDAY NIGHT WILL FEATURE MAINLY FAIR WEATHER. ANY SNOW
SHOWERS OVER THE SOUTHERN POCONOS AND NORTHERN NEW JERSEY WILL
DIMINISH BEFORE NOON ON FRIDAY. TEMPERATURES WILL BE SEASONABLE WITH
MID TO UPPER 30S MOST AREAS. SOME LOW CHC POPS WERE PAINTED ACROSS
THE WEST AFTER MIDNIGHT FRI, BUT THIS WAS MAINLY TO KEEP CONTINUITY
WITH SURROUNDING OFFICES. I THINK THAT ANY MEASURABLE PRECIP WILL
OCCUR AFTER 12Z SAT.

THE NEXT SYNOPTIC SYSTEM WILL MOVE UP THE OHIO VALLEY SATURDAY AND
THEN AFFECT OUR AREA SATURDAY AND SATURDAY NIGHT. DEPENDING ON
WHICH MODEL YOU BELIEVE, A VARIETY OF WINTER WEATHER SCENARIOS ARE
POSSIBLE. THE GFS IS FAIRLY QUICK WITH THE LOW AND DOES NOT ALLOW
WARMER AIR TO ARRIVE FOR OUR AREA. IT HAS A SNOWY SOLUTION FOR OUR
NORTHERN AND CENTRAL AREAS. THE NAM HAS LEANED THIS WAY TOO, BUT
IT IS SLOWER AND EVENTUALLY BRINGS WARMER AIR NORTHWARD AND
CHANGES THE STEADY SNOWS TO RAIN LATER SAT. BOTH THE NAM AND GFS
SHOW THE SFC LOW MOVING ALONG THE PA/MD BOARDER WHICH PUTS MORE OF
OUR FORECAST AREA ON THE COLDER SIDE OF THE STORM.

THE MODEL THAT I HAVE USED FOR THIS FCST IS THE 12Z ECMWF, WHICH
LOOKS SIMILAR TO THE 00Z RUN. IT EMPHASIZES A SLOWER AND WARMER
SOLUTION WITH THE SFC LOW GOING ACROSS OUR NORTHERN COUNTIES. IT
IS COLD ENOUGH FOR SNOW TO OCCUR AT FIRST, BUT ACCUMULATIONS SHOULD
BE TEMPERED BY THE FACT THAT IT WILL CHANGE TO RAIN, OR A RAIN AND
SNOW MIX BEFORE ENDING SAT NIGHT. THE QPF ON THE ECMWF IS ALSO
LIGHTER THAN THE OTHER TWO MODELS. IT IS SHOWING ROUGHLY .2 TO .4
ACROSS OUR FORECAST AREA, WHICH IS OVERALL LIGHTER THAN THE NAM OR
GFS. I HAVE INCLUDED SOME LIGHT TO MODERATE (POCONOS) ACCUMULATIONS
IN THE SATURDAY AND SATURDAY NIGHT GRIDS FOR NOW. ANY CHANGE IN
THE TRACK OR SPEED MAY WARRANT THE NEED FOR A WATCH, BUT THERE IS
NOT ENOUGH CERTAINTY IN WARNING CRITERIA QPF PRESENTLY TO JUSTIFY
ONE IN THE 4TH PERIOD.

&&

.LONG TERM /SUNDAY THROUGH THURSDAY/...
THE HPC PROGS AND DISCUSSIONS FAVOR THE ECMWF 00Z/08 SOLUTION FOR
THE EXTENDED PERIOD. IT FEATURES A PATTERN OF FAST MOVING SYSTEMS
WITH AN EAST COAST TROUGH THAT BECOMES MORE AMPLIFIED WITH TIME.
TEMPERATURES IN THE EXTENDED PERIOD WILL GENERALLY BE BELOW NORMAL
WITH THE COLDEST AIR ARRIVING TOWARD THE MIDDLE OF NEXT WEEK.

SUNDAY WILL BEGIN WITH THE STORM (FROM THE END OF THE SHORT TERM)
PULLING AWAY ACROSS NEW ENGLAND AND INTO THE CANADIAN MARITIME
PROVINCES. THE 00Z ECMWF SHOWS A 999 MB LOW OVER CT AT 12Z SUN WHICH
MOVES TO NEWFOUNDLAND BY 00Z MON WHILE DEEPENING TO 986 MB. THE
STEADY PRECIP FROM THIS FEATURE WILL LIKELY HAVE ENDED ACROSS OUR
ZONES BY SUN MORNING, SO DAYTIME POPS WERE KEPT AT THE SLGT CHC
RANGE IN MOST AREAS. THE CHC POPS ACROSS THE SOUTHERN POCONOS AND
NRN NJ WILL REMAIN AS SOME ACTIVITY DOWNWIND OF THE GREAT LAKES MAY
LINGER. WEAK HIGH PRESSURE WILL RIDGE IN LATE DURING THE WEEKEND AND
EARLY NEXT WEEK WITH MAINLY FAIR WEATHER ACROSS MOST AREAS. MAX
TEMPERATURES SUNDAY WILL BE AROUND 5 TO 10 DEGREES BELOW NORMAL AND
WITH A MODEST WEST TO NORTHWEST WIND CONDITIONS WILL BE QUITE BRISK.
WIND CHILL READINGS LIKELY IN THE TEENS OVER MOST AREAS ON SUNDAY.

THE NEXT DISTURBANCE IN THE QUICK PACED UPPER FLOW WILL MOVE TOWARD
THE AREA TUESDAY. THE ECMWF PROGS SHOW THAT A LOW WILL ADVANCE
ACROSS THE GREAT LAKES MON NIGHT AND BE LOCATED OVER SRN ONTARIO BY
12Z TUE. AS THIS LOW PASSES EAST. A COASTAL WILL PROBABLY DEVELOP
OFF THE NORTHERN ATLANTIC SHORE AND ABSORB THE NORTHERN LOW. THIS
SYSTEM DEEPENS AND PULLS OFF TO THE NORTHEAST WED. CHC POPS ARE IN
THE FORECAST FOR THIS PERIOD PRESENTLY. ARCTIC AIR WILL DEEPEN
ACROSS THE AREA IN THE WAKE OF THIS SYSTEM AND HIGHS IN THE WED AND
THU PERIOD NEXT WEEK WILL BE MAINLY IN THE TEENS AND 20S. THESE
READINGS WILL BE 10 TO 15 DEGREES BELOW NORMAL.

&&

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

THE SOON TO BE ISSUED TAFS WILL HAVE A VFR FORECAST THROUGHOUT.
FORECAST MODELS AND UPSTREAM OBSERVATIONS ARE SHOWING PLENTY OF VFR
SC CLOUDS AROUND. THE FLOW REMAINS CYCLONIC THROUGH THE NIGHT ALOFT
COUPLED WITH SOME WEAK UPPER AIR DISTURBANCES. THUS WE HAVE KEPT A
SC VFR CIG (BETWEEN 4 AND 5K) INTO A GOOD PART OF THE EVENING AND
KEPT IN OVERNIGHT AT OUR NW TERMINALS. WE DID MAINTAIN SOME
GUSTINESS WITH THE WINDS THROUGH THE EVENING.

ON FRIDAY THE FORECAST MODELS ARE STILL SHOWING SOME LOW LEVEL
MOISTURE ABOVE A FAIRLY HIGH SUBSIDENCE INVERSION. THIS SHOULD
PERMIT MORE SC CLOUDS TO FORM WITH DAYTIME HEATING AND PROBABLY
SPREAD INTO A VFR CIG ESP FROM THE KPHL AREA TERMINALS
NORTHWESTWARD. THERE STILL SHOULD BE SOME GUSTY W TO NW WINDS
AROUND. FORECAST SOUNDINGS ARE SUGGESTING THE STRONGEST WINDS MIGHT
OCCUR DURING THE MORNING AS A MORE EFFICIENT OVERTURNING OF THE LOW
LEVEL ATMOSPHERE WILL OCCUR AFTER A COUPLE OF HOURS OF DAYTIME
HEATING. WINDS SHOULD FINALLY DECOUPLE TOWARD EVENING AND WE SHOULD
LOSE THE SC CLOUDS JUST IN TIME TO SEE THE CIRRUS START ARRIVING
WITH THE WEEKEND LOW PRESSURE SYSTEM.

OUTLOOK...
THE FAST FLOW ALOFT CONTINUES TO BE THE MAIN STORY AND ITS THAT JET
THAT WILL BRING QUICK MOVING STORMS ACROSS THE TERMINAL CONTROL
AREA. THE NEXT ARRIVES ON SATURDAY INTO SUNDAY WITH REINFORCED COLD
AIR BEHIND IT, AND ANOTHER AROUND THE 13TH FOLLOWED BY A BLAST OF
COLD AIR RIGHT FROM THE ARCTIC CIRCLE. IT WILL REALLY BE COLD NEXT
WEDNESDAY/THURSDAY.

THE SYSTEM ARRIVING ON SATURDAY WILL BRING THE NEXT CHANCE OF
PRECIPITATION. IT PRESENTLY LOOKS TO FALL IN THE FORM OF SNOW
POSSIBLY TRANSITIONING TO RAIN, ESPECIALLY SOUTH. SOUNDINGS STILL
SUGGEST THAT A TRANSITIONING COULD GO THROUGH SLEET AND FREEZING
RAIN. DETERIORATING FLIGHT CONDITIONS ARE EXPECTED AS THE
PRECIPITATION ADVANCES/ARRIVES.

&&

.MARINE...
WE WILL DROP THE GALE WARNING FOR THE NORTHERN COASTAL WATERS AND
ISSUE A SMALL CRAFT ADVISORY. ELSEWHERE THE SMALL CRAFT ADVISORY
REMAINS IN EFFECT. IT LOOKS AS THOUGH SCA WINDS AND SEAS SHOULD
PERSIST INTO FRIDAY AFTERNOON ON THE OCEAN. OVER DELAWARE BAY...WE
KEPT THE SAME TIMING AS PER A DIRECTION FCST TO BE STRAIGHT DOWN IT.
THEY ARE EXPECTED TO LOSE THE SCA WINDS FIRST ON FRIDAY.

WE SHOULD THEN HAVE A PERIOD BELOW SCA WINDS BEFORE WINDS AND SEAS
AGAIN RAMP UP IN ADVANCE OF THE NEXT LOW PRESSURE SYSTEM. MODEL
GUIDANCE IS SHOWING SOME PRETTY VARIABLE SOLUTIONS WRT TO BOTH TRACK
AND INTENSITY. WE BELIEVE ITS STRENGTH IN ALL LIKELIHOOD WILL TAKE
US AGAIN TO SCA CONDITIONS LATER SATURDAY INTO SUNDAY. WINDS AND
SEAS SHOULD THEN DIMINISH AGAIN LATER SUNDAY INTO MONDAY. SCA IF NOT
GALE CONDITIONS BEFORE ALL IS SAID AND DONE SHOULD RETURN BEHIND THE
NEXT CFP LATER IN THE DAY ON TUESDAY.

&&

.HYDROLOGY...
THE RANCOCAS CREEK IS EXPECTED TO CREST NEAR THE CAUTION STAGE ON
FRIDAY. THE CAUSEWAY AT GRIGGSTOWN ALONG THE MILLSTONE RIVER IS
PRESENTLY CLOSED DUE TO WATER LEVELS. THE MILLSTONE CRESTED. RIVER
STATEMENTS HAVE BEEN ISSUED FOR THESE EVENTS.

&&

.TIDES/COASTAL FLOODING...
THE LOW WATER ADVISORY REMAINS IN EFFECT FOR THE LOWER DELAWARE BAY
AND THE COASTAL ATLANTIC. DEPARTURES HAVE CLOSED A BIT, BUT CURRENT
PROJECTIONS WOULD STILL GET A NUMBER OF SITES TO OUR LOW WATER
CRITERIA.
