...THE LOW WATER ADVISORY HAS BEEN CANCELLED...

TIDAL DEPARTURES HAVE DIMINISHED AND THE LOW WATER ADVISORY IS NO
LONGER IN EFFECT.

ALTHOUGH THE LOW WATER LEVELS WILL IMPROVE SOMEWHAT THIS EVENING
AND OVERNIGHT, OFFSHORE WINDS WILL RESUME SUNDAY AND BECOME QUITE
STRONG BY SUNDAY NIGHT, CONTINUING INTO MONDAY. THIS WILL CAUSE A
DECREASE IN WATER LEVELS ONCE AGAIN, AND ANOTHER LOW WATER
ADVISORY MAY BE NEEDED. SO, MARINERS ARE URGED TO MONITOR LATER
STATEMENTS REGARDING A POTENTIAL LOW WATER SITUATION SUNDAY NIGHT
AND MONDAY.

AREA FORECAST DISCUSSION...UPDATE
NATIONAL WEATHER SERVICE MOUNT HOLLY NJ
155 PM EST FRI FEB 16 2007

.OVERVIEW/...
NOAA REPORTS JAN TEMP NEAR AVERAGE FOR U.S., BUT LOOKING AT THE
SNOWPACK OVER THE LOWER 48 TODAY FEB MAY BE ON THE MINUS SIDE.
SNOWCOVER IS BELOW 38 DEG N LATITUDE FROM MID ATLANTIC AND AS FAR
WEST AS THE ROCKIES(CANT REMEMBER LAST TIME I SAW THIS) AND THERE
IS STILL MORE COLD AIR TO COME ESPECIALLY EAST OF THE ROCKIES TO THE
EAST COAST THROUGH THE 20TH, HOWEVER, HALF THE COUNTRY WILL BE ABOVE
NORMAL FROM THE 23RD THROUGH THE END OF THE MONTH. WILL CLOSELY
FOLLOW THE FEB TOTALS. AND, WHY AM I TALKING WARMUP? THE SNOW COVER
IS ONE THING, BUT LOOKING AT THE MODELS, WE SEE THE POTENTIAL OF A
WET PERIOD ON THE 22ND, STAYING WARM WITH ANOTHER MILD HEAVY RAIN
POSSIBLE FOR THE 26TH. ITS TOO EARLY TO BE MORE SPECIF, BUT I WOULD
CERTAINLY BEGIN THINKING ABOUT THE POSSIBILITY OF SOME MELTING
RAINS AND RIVER FLOODING. JUST SOME FOOD FOR THOUGHT.

NOTE - FOR THE LATEST ON THE VALENTINES DAY STORM PLEASE SEE...
WWW.ERH.NOAA.GOV/PHI/STORMS/02142007.HTLM

&&

.SHORT TERM /TONIGHT THROUGH SUNDAY NIGHT/...
COLD TODAY AND THE WIND WHIPPING RIGHT THROUGH YOU. SEEMS THIS COLD
WIND GRADIENT HAS BEEN WITH US FOR MUCH OF THE MONTH. IN FACT THE
ONLY DAY WITH A MILD DIRECTION WAS ON THE 1ST(210 DEGREES). THIS
FEB A CALM DAY IS 20 TO 25 MPH. STILL FEELING THE AFFECTS OF THE LOW
OVER QUEBEC PROVINCE INTERACTING WITH THE HIGH BUILDING INTO THE
REGION. CAA NEXT SEVERAL DAYS BUT THE 80H WINDS BACK TO THE SW IN
RESPONSE TO ARRIVING LOW PRESSURE SATURDAY EVENING. THE LOW LOSES
IDENTITY CROSSING THE APPALACHIANS THEN REFORMS OVER SOUTHERN NEW
JERSEY SATURDAY NIGHT. WE CAN EXPECT TO SEE SOME SNOW SHOWERS AS THE
UPPER TROUGH MOVES EAST, BUT NOT MUCH AND NOT FOR EVERYONE. BAGGINESS
IN THE ISOBARS SHOWS BIT OF A STRONGER SYSTEM OFF THE NC COAST WITH
QPF AMOUNTS OF 1/2INCH AND REMAINING OUT TO SEA.

AS THE LOW WRAPS UP SUNDAY NIGHT, A POOL OF COLD AIR OVER THE GREAT
LAKES WILL PLUNGE SOUTH LATE SUNDAY INTO MONDAY. THE WINDS ON THE
BACK SIDE OF THE STORM ARE STRAIGHT FROM THE NORTH SO IT IS GOING TO
BE ANOTHER COLD SNAP FOR SURE ON MONDAY. I MAY HAVE TO PLAY WITH THE
HIGH TEMP FOR MONDAY ESPECIALLY WITH THE FRESH SNOW COVER. 80H WINDS
WILL BE HOWLING DOWN FROM THE HUDSON VALLEY AT 50 KNOTS. THE
REINFORCED COLD SNAP WILL BE SHORT LIVED AS WE TAKE THE NEXT STEP
INTO THE LONG TERM. WE SAY GOODBYE TO THE UPPER CYCLONE AND WATCH AS
THE FLOW MODIFIES IN THE MID LEVELS ACROSS THE ENTIRE U.S.

&&

.LONG TERM /MONDAY THROUGH FRIDAY/...

WITH THE COLD AIR MOVING AWAY, WE TURN OUR ATTENTION TO A NOTICEABLE
WARM UP. LETS NOT GO TOO CRAZY, WITH THE SNOW STILL ON THE GROUND,
BUT ABSENT ANY WIND, IT WILL BE FEELING VERY NICE OUTSIDE. WITH THE
RIDGE MOVING OFFSHORE MONDAY NIGHT STRONG WARM AIR ADVECTION WILL
GATHER IN THE SOUTHERN PLAINS AND WAIT THE DEVELOPMENT OF A SFC LOW,
THE SOUTHERN EXTENT OF A FRONT THAT EXTENDS NORTHEAST TO ANOTHER
COLD LOW IN THE GREAT LAKES. COMBINE THIS WITH THE SURFACE HIGH OFF
THE SOUTHEAST COAST AND WELL HAVE A SOUTHWEST WIND. THE SFC LOW
TRACKS TO THE LOWER MISSISSIPPI VALLEY WITH CONVECTIVE PRECIPITATION
BREAKING OUT. THE LOW MOVES JUST SLIGHTLY NORTH OF EAST WITH PLUS 2
DEG C TEMPS OVER OUR CWA BEFORE THE RAIN BEGINS. THE LOW TRACKS OFF
THE DELMARVA WITH A HEAVY BAND OF CONVECTION REMAINING OFFSHORE BUT
WRAP AROUND 1.25 INCHES OF LIQUID OVER THE NORTHERN DELMARVA, AND ACROSS
THROUGH DELAWARE AND SOUTHERN NEW JERSEY. WITH THIS FIRST RAIN
EVENT, THE NORTHERN SNOWIEST PART OF THE REGION WILL RECEIVE VERY
LITTLE PRECIPITATION. THE SYSTEM ENDS AS A FEW SNOW SHOWERS ACROSS
THE EXTREME NORTHERN COUNTIES. TEMPERATURES BEGIN A CLIMB TO THE 40S
AND THEN 50S IN SOME SPOTS ON WED.

NEXT ON THE MENU, AFTER A TWO DAY PERIOD WITH WEAK RIDGE OVER THE
AREA AND MODEST TEMPERATURES ABOUT NORMAL. FRIDAYS TEMPERATURES WILL
BE BACK INTO THE MID TO UPPER 40S SOUTHERN AREAS AND LOWER 40S
NORTH. IN BOTH CASES, ABOVE NORMAL.

I MENTIONED A SECOND RAIN EVENT IN THE OVERVIEW, BUT THAT IS OUTSIDE
OF THE LONG RANGE PERIOD. SUFFICE TO SAY A SIGNIFICANT CHANGE IS ON
THE WAY. WELL GET TO ADDRESS THIS MORE OVER THE WEEKEND.

&&

.AVIATION...
CLEAR SKIES EXPECTED THRU THE NIGHT WEST WINDS WILL EASE UP OVER
NIGHT AND SWING TO MORE SOUTHWESTERLY AFTER 12Z.

&&

.MARINE...
WILL KEEP THE SCA FLAGS FLYING FOR THE EARLY PART OF THE FORECAST
WILL KEEP THE EXPIRATION TIME TO 15Z SATURDAY FOR THE NORTHERN
COASTAL WATERS AND UNTIL 06Z FOR THE SOUTHERN COASTAL WATERS AND
DELAWARE BAY.

THE SYNOPTIC SITUATION SHOWS THAT THE SMALL CRAFT AND GALE FLAGS
WILL BE REQUIRED ONCE AGAIN LATE SUNDAY INTO MONDAY. A COLD FRONT
WILL CROSS THE COASTAL WATER SUNDAY MORNING AND A LOW PRESSURE
SYSTEM WILL DEVELOP ALONG IT. THE LOW WILL QUICKLY DEEPEN WELL
OFFSHORE, BUT THE GRADIENT WILL BECOME STRONG OVER THE WATERS.

&&

.TIDES...
RECONSIDERED THE TIDAL DEPARTURES AND WITH THE NEW MOON ON SATURDAY
OUR ASTRONOMICAL TIDES WILL START AT -0.5 WITH AN ADDED DEPARTURE OF
1.5 FT ON THE STORM SURGE. TWO FEET BELOW MLLW IS THE THRESHOLD FOR
CONCERN.
