AREA FORECAST DISCUSSION...UPDATED
NATIONAL WEATHER SERVICE MOUNT HOLLY NJ
934 PM EST MON MAR 5 2007
UPDATE...
PUBLIC...NOW THAT THE SQUALLS ARE GONE AND MOST OF THE CLOUDS
HAVE ALSO DISPTED...WE WILL UPDATE THE ZONES AND SPS. BASED ON
THEIR 00Z 6HR FCST THE WRF-NMM WAS MUCH BETTER WITH THE H8 TEMPS
THAN THE GFS WHICH WAS RUNNING WITH ABT A 2-3C TOO COLD ERROR ACRS
NEARBY CANADA/NY/NEW ENG. OTHERWISE THE 18Z RUNS PULLED NO
SURPRISES WRT TO WEDNESDAYS CLIPPER. THE STORM TOTAL WAS SO CLOSE
AT PHL I WAS HAVING A HARD TIME DISTINGUISHING THE 12Z RUN FROM
THE 18Z RUN. WE/RE STILL MEASURING ABT 50KTS OF FWD MOTION FOR THE
CLIPPER (LIVING UP TO ITS NAME) ON THE GFS AND ABT 60KTS ON THE
ECMWF.
IN PAST WINTERS THESE WERE EVENTS THAT THE ETA HANDLED BETTER THAN
THE GFS...ATTM BOTH THE WRF-NMM AND GFS ARE PRETTY CLOSE. THE WRF IS
SLIGHTLY FTHR N WITH THE TRACK AND SLOR. NEVER PAYS TO BE SLOW WITH
THESE SYSTEMS ALTHO AIR MASS THE SNOW WILL BE FALLING INTO INIT WILL
BE MIGHTY DRY. WE DID LOOK UP THE FLUFFIER AND AT LEAST 4 EVENTS IN
PHL SINCE 1989 AND THE SNOW TO WATER EQUIV RATIO AVERAGED AROUND
15:1 FOR THEM. THE FLUFF FACTOR WILL BE NEEDED SINCE ANY ONE LOCN IS
FCST TO BE IN THE PROVERBIAL DENDRITIC ZONE/OMEGA CROSS HAIRS FOR
ONLY A COUPLE OF HOURS. FOR MOST OF US THAT WOULD MEAN AS PER THE
LATEST GUID THAT THE HEAVIEST SNOW WOULD OCR DURG THE AFTN HRS ON
WED.
MARINE...TIDAL DEPARTURES ARE DROPPING RATHER QUICKLY OVER THE
ATLANTIC AND DELAWARE SHORE AREAS THIS EVENING. THE DEPARTURES
ARE PRESENTLY 1.5 TO 2.0 FEET BELOW NORMAL. SINCE THE NW TO W WIND
WILL PERSIST OVERNIGHT...A LOW WATER ADVISORY HAS BEEN ISSUED FOR
THE UPCOMING LOW TIDE CYCLE. THE ADVISORY HAS ALSO BEEN ISSUED FOR
DELAWARE BAY, SINCE THE LOW TIDE WILL OCCUR THERE TOWARDS MORNING
AND THE EFFECTS ARE EXPECTED TO PERSIST AT THOSE HOURS.
