AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE TAUNTON MA
1219 PM EDT THU SEP 15 2005

.SHORT TERM (REST OF TODAY)...
AREAS OF HEAVY SHOWERS AND THUNDERSTORMS AFFECTED (AND WILL CONTINUE
TO AFFECT) MOST OF SOUTHERN NEW ENGLAND. REPORTS OF RAINFALL GREATER
THAN 2 INCHES HAVE ALREADY OCCURRED ACROSS THE REGION...INCLUDING
CRANSTON...MILLBURY...AND WELLESLEY HILLS. THESE RAINFALL AMOUNTS
HAVE OCCURRED IN A SHORT PERIOD OF TIME...CAUSING SOME ROAD CLOSURES
IN THE CRANSTON AREA. VARIOUS FLOOD STATEMENTS HAVE BEEN ISSUED THIS
MORNING ADDRESSING THIS HEAVY RAINFALL.

SCATTERED HEAVY SHOWERS...WITH EMBEDDED THUNDERSTORMS...WILL CONTINUE
FOR THE REMAINDER OF TODAY INTO THIS EVENING AS THE COLD FRONT OVER
NEW YORK PUSHES EAST. THE GFS HANDLED THE PLACEMENT OF THIS MORNINGS
RAINFALL WELL...SO WILL CONTINUE TO GO WITH THE GFS IN REGARDS TO
PLACEMENT OF THE RAINFALL (BUT NOT FOR AMOUNTS). FOR AMOUNTS...USED
HPC QPF AS A BASELINE AND RAISED THE AMOUNTS SOME TO ACCOUNT FOR
HEAVY RAINFALL.

MARINE...BUOY OBSERVATIONS INDICATE SEAS ARE 3 FEET OFF OF MASS BAY.
THEREFORE...UPDATED THE MARINE FORECAST BY RAISING THE SEAS ACROSS
THIS LOCATION.

PLEASE SEE PREVIOUS DISCUSSION BELOW FOR MORE DETAILS ON THE
FORECAST.

.PREVIOUS DISCUSSION...
(ISSUED 520 AM EDT THU SEP 15 2005)

..HEAVY RAIN AND MULTIPLE OPHELIA ADVERSE ELEMENTS ARE THE PRIMARY
FOCUS OF THIS MID SHIFT FORECAST PACKAGE AS UNSETTLED WX PATTERN
DEVELOPS NEXT 5 DAYS...

PRODUCTS ARE BASICALLY POSTED.

PLEASE NOTE...WE HIGHLIGHTED GALE AND SCA WARNING BEYOND THE NORMAL
3RD PRD OF MARINE/ADVY/WARNINGS TO HIGHLIGHT ATTN ON THE NEW
09Z/15 TRACK OF THE OPHELIA.  IF FCST COLLABORATION WITH TPC LATER
TODAY CONTS TO INDICATE OPHELIAS TRACK WILL REMAIN WITHIN 60 MI OF
NANTUCKET SAT MORNING....THEN ALL THESE LONGER RANGE ADVY/WARNINGS
WILL BE RECONSTRUCTED UNDER TPC PRODUCT HEADERS (WATCHES ETC). THAT
IS NOT THE CASE RIGHT NOW...WE HAVE A LITTLE MORE TIME BEFORE WE NEED
TO COMMIT ON WATCHES.

OPHELIA...
YOU HAVE SEEN THE 11PM EDT TPC DISC AND CONICAL PROBS OF TS WIND. WE
ARE REVIEWING MULTIPLES SOURCES OF DATA FOR IN-HOUSE CONFERENCING
PRIOR TO OFFICIAL 4-5AM EDT/15 RELEASE. PLS REF TPC FOR OFFICIAL
ADVISORIES AND OUR SPS STATEMENTS FOR IMPACTS HERE.

FWIW...THE NEW 00Z/15 GFDL CONTS FURTHER NW OF PRIOR TRACKS AND IF
SOLELY ACCEPTED AS GUIDANCE...WOULD AFFECT MUCH OF THE SNE COAST FM
WST TO PYM-40013 SEWD. NEW 00Z/15 EC HAS A STG LOW SOMEWHERE IN THE
NW GME BY 00Z SUN.

APPEARS TO US THAT WE HAVE ABOUT 45 HRS OF LEAD TIME IF ANYTHING IS
TRACKED CLOSER TO OUR AREA PER TPC.

PRECONF AT 345 AM WITH TPC WILL YIELD A CLOSER TRACK TO CAPE COD.
PLEASE GIVE US TIME TO GENERATE THE PRODUCTS AND FOR TPC TO GENERATE
ALL THEIR DETAILS. WE SHOULD HAVE ALL PRODUCTS FILED BY 5 AM.

MODELS...
GFS/ECMWF MERGE ARE THE MODELS THAT WILL RELY ON HEAVILY FOR THIS
FCST PKG THRU THE SHORT TERM WHICH IS FRIDAY EVENING. HAVE APPLIED A
BIT OF THE GGEM AS WELL.

SHORT TERM (TODAY THROUGH FRIDAY)...
DETAILS LATER BUT 00Z/15 MAV POPS AND TEMPS LOOK DECENT AND WE WILL
MERGE WITH OUR PRIOR FCST AND CHECK AGAINST OTHER AVBL MOS.

BTW...NEXT WEEK...BARRING ANOTHER HURRICANE...WE SHOULD SEE 12Z RUNS
OF MEX DATA OUT TO DAY 7...AKIN TO OUR 00Z RUNS....AVBL PROB ARD 17Z.
CRITICAL WX DAYS PRECENTED THE START OF THIS THIS WEEK.

HYDROLOGY...
00Z/14 GFS IS GOING TO PROBABLY BE RIGHT ON THE MONEY...ANTICIPATING
BY THIS THU EVE SPOT 3-4 RAINS IN ROUGHLY THE I95 CORRIDOR. THE
COMBINATION OF INSTAB...CNV ALONG THE FRONT AND PW ARD 2 SHOULD
EASILY DOUSE THE REGION WITH NEEDED RAINS..ALBIET IN TOO SHORT A
PERIOD OF TIME. HOWEVER FFG REFLECTING ANTECDENT CONDS SHOULD PREVENT
FF BUT WE WILL ISSUE AN FLS FOR POOR DRAINAGE FLOODING TODAY.

ALREADY 1.34 IN 1 HR AT OXFORD CT ENDING 0655Z  SO WHILE THE BROAD
AREA OF GFS 1 + MAY BE TOO LARGE...THERE IS NO DOUBT IN MY MIND THAT
WE DOUBLE THE MAX GFS OUTPUT FOR TODAY. PWS ARE GOING OVER 2.
EXACTLY WHERE THIS OCCURS...STILL UNK.

INTERESTING TO CONSIDER THE POSSIBLITY OF CSI FORCING FRI NIGHT SAT
MORNING FURTHER W THAN THE 00Z/15 GFS WOULD LEAD ONE TO BELEIVE
IE W OF THE CC CANAL...MAYBE ANOTHER R+ AXIS NZW-PYM-EWB-UUU
CORRIDOR.

WHEN WE ADD IT ALL UP...TO US...IT APPEARS SPOT 5+ RAINS
CONT PROBABLE I95 CORRIDOR EWD BY SAT EVE...UNLESS OPHELIA STAYS ON
LAST EVENINGS TPC TRACK...THEN ONLY SPOT 3-4.

WE WILL REMAIN IN DEFAULT MODE FOR THE RADAR... IT DETECTED 1.2 NR
OXC. ITS RUNNING SHORT BUT CONSISTENT AT THAT RANGE. SUSPECT WEVE
HAD 2 JUST W OF OXC.

&

LONG TERM (FRIDAY NIGHT THROUGH WEDNESDAY)...
.UNSETTLED WEATHER THROUGH THE WEEKEND...
MAIN CONCERN WILL BE TROPICAL STORM OPHELIA AS IT TRACKS NORTHEAST
FROM THE MID ATLANTIC COAST FRIDAY NIGHT. A SHORT WAVE CURRENTLY
OVER THE MISSOURI VALLEY WILL LIFT NORTHEAST INTO THE EASTERN OHIO
VALLEY FRIDAY NIGHT. MEANWHILE THE NORTHERN ATLANTIC RIDGE WILL
STRENGHTEN. THIS COMBINATION WILL ALLOW OPHELIA TO BECOME CAPTURED
INTO THE UPPER LEVEL TROUGH...ALIGNING THE 250 MILLIBAR JET STREAK
FROM SOUTHWEST TO NORTHEAST FROM THE MID ATLANTIC COAST INTO NEW
ENGLAND. OVERALL THIS WILL CAUSE OPHELIA TO TRACK SLIGHTLY FURTHER
TO THE LEFT...AND CLOSER TO THE COAST. THE 00Z GFS AND ECMWF OFFER
FAIRLY SIMILAR SOLUTIONS...WHILE THE 00Z ENSEMBLE 250 MILLIBAR
HEIGHT FIELDS AND SURFACE LOW PRESSURE TRACKS SHOW SOME DEVIATION.
OVERALL ADVERTISED LIKELY TO CATEGORICAL POPS FRIDAY NIGHT THROUGH
SATURDAY NIGHT...WITH FAVORABLE UPPER LEVEL DIVERGENCE...INCREASING
ISENTROPIC LIFT DUE TO WARM AIR ADVECTION PATTERN...AND MOISTURE
CONVERGENCE. THE TRAILING SHORT WAVE BEHIND OPHELIA IS EXPECTED TO
CROSS THE REGION SATURDAY NIGHT AND SUNDAY. WEAK UPPER LEVEL RIDGING
BEHIND THE SHORT WAVE SHOULD BRING DRY CONDITIONS MONDAY. THIS WILL
BE FOLLOWED BY A COLD FRONT TUESDAY. OVERALL PLACED MAIN EMPHASIS
OF FORECAST THROUGH THE WEEKEND. ADJUSTED TEMPERATURES UPWARDS ABOUT
5 DEGREES SATURDAY NIGHT DUE TO CLOUD COVER AND PRECIPITATION.

A SPECIAL WEATHER STATEMENT WILL BE RE-ISSUED WITH AN OVERVIEW ON
OPHELIAS POTENTIAL IMPACTS TO SOUTHERN NEW ENGLAND.

AVIATION...
SPOTTY IFR CIGS/VSBY IN SHOWERS/FOG TODAY...BECOMING MORE WIDESPREAD
TONIGHT AS WK CFP SWINGS EAST.  GFS KI OF 37 TODAY USED FOR THUNDER
AND GFS KI 36 USED FOR T TONIGHT ON CC IN THE GRIDS.

PLS SEE TAFS FOR THE DETAILS.

MARINE...
SHORT TERM (THRU FRIDAY)...SCA AS PER HEADLINES BELOW.  START THE
INCREASING SEAS MIDDAY TODAY. USED WNA AS IS...WHICH IS LESS THAN
WHAT WE HAD GOING.

FWIW...WE HAVE CKD HURRICANE VSN OF THE WNA VS NORMAL WNA. SEAS ARE
2M HIGHER MIDDAY SATURDAY IN THE HURR VSN (6M AT 44018 OR NEARLY 20FT
FOR A SHORT PRD OF TIME).  THE HURR MODEL RAISES SEAS 9 FT IN 3 HRS
WITH THE CENTER OF OPHELIA. WE WILL TRY AND WORD EXTREME SHORT TERM
CHANGE IN SEAS STATE SAT MORNING WITH SLOW DECREASE THEREAFTER...
PROVIDING OUR EXPECTATIONS OF TIMING IS ACCURATE.

FCST SEAS SUGGEST HVY SURF MAY BE NEEDED FRI.

LONG TERM: FOLLOWED THE 00Z NAH WAVEHEIGHT GUIDANCE IN THE LONG
TERM THROUGH 12Z SUNDAY. FEEL THE WNA IS TOO CONSERVATIVE GIVEN
PROJECTED STORM TRACK. FOLLOWED THE WNA GUIDANCE STARTING SUNDAY.
WIND GUSTS TO 50 KT AND SEAS AROUND 20FT WILL BE POSSIBLE ACROSS THE
SOUTHEASTERN WATERS. COASTAL FLOODING MAY OCCUR ACROSS CAPE COD AND
THE ISLANDS DUE TO TIDAL LEVELS...WIND WAVE ACTION AND STORM SURGE
SATURDAY. PLAN TO ISSUE A MARINE WEATHER STATEMENT HIGHLIGHTING
THESE CONCERNS.

...MARINERS AND THOSE WITH RECREATIONAL INTERESTS ALONG THE
SOUTHEASTERN NEW ENGLAND COAST AND THE ADJACENT WATERS SHOULD
CONTINUE TO MONITOR THE LATEST STATEMENTS FROM THE TROPICAL
PREDICTION CENTER ON HURRICANE OPHELIA...

THE LATEST FORECAST GUIDANCE FROM THE TROPICAL PREDICTION CENTER
INDICATES THAT HURRICANE OPHELIA WILL TRACK A LITTLE CLOSER TO THE
COAST. THIS TRACK WOULD RESULT IN A GREATER IMPACT ON SOUTHEAST
COASTAL NEW ENGLAND AND THE ADJACENT COASTAL WATERS.

HURRICANE OPHELIA WILL CONTINUE TO LASH THE CAROLINA COAST TODAY THEN
ACCELERATE NORTHEASTWARD FRIDAY OFF THE DELMARVA COAST. OPHELIA IS
FORECAST TO GRADUALLY WEAKEN TO A TROPICAL STORM THEN BECOME
EXTRATROPICAL AS SHE PASSES LESS THAN 100 MILES SOUTH SOUTHEAST OF
NANTUCKET SATURDAY MORNING.

THIS TRACK WOULD BRING TROPICAL STORM CONDITIONS TO CAPE COD AND THE
ISLANDS LATE FRIDAY NIGHT AND SATURDAY MORNING. THE POTENTIAL EXISTS
FOR WIND GUSTS FROM 50 TO 60 MPH AND SEAS FROM 15 TO 20 FEET ACROSS
PORTIONS OF THE SOUTHEASTERN NEW ENGLAND COASTAL WATERS. OPHELIAS
WINDS AND SEAS MAY COMPARE TO A POWERFUL MID WINTER NOREASTER.

SCATTERED POWER OUTAGES AND PROPERTY DAMAGE MAY OCCUR ON NANTUCKET
ISLAND LATE FRIDAY NIGHT AND SATURDAY. BEACH EROSION CAN BE
EXPECTED OVER PORTIONS OF EASTERN CAPE COD AND THE ISLANDS. BE
PREPARED FOR RIP CURRENTS AS WELL AS STEEP AND QUICKLY BUILDING SEAS
LATE FRIDAY NIGHT AND SATURDAY MORNING. THESE QUICKLY BUILDING SEAS
WILL RAPIDLY PRODUCE HAZARDOUS CONDITIONS FOR MARINERS AND THOSE
WITH RECREATIONAL INTERESTS.

COASTAL FLOODING WILL BE ALSO POSSIBLE DURING THE TIME OF MORNING TO
MIDDAY HIGH TIDE SATURDAY MAINLY ACROSS CAPE COD AND THE ISLANDS
DEPENDING ON THE TIMING...EXACT TRACK AND STRENGTH OF OPHELIA.

OUR WEATHER IS EXPECTED TO REMAIN UNSETTLED THROUGH THE WEEKEND.
SOME OF THE MOISTURE ASSOCIATED WITH OPHELIA WILL INTERACT WITH AN
APPROACHING COLD FRONT TO PRODUCE A BAND OF HEAVY SHOWERS AND
THUNDERSTORMS IN PORTIONS OF THE REGION TODAY.

IN ADDITION...PERIODIC SHOWERS WILL BECOME MORE WIDESPREAD BY FRIDAY
EVENING AS OPHELIA APPROACHES FROM THE SOUTH. RAIN WILL BE LOCALLY
HEAVY...ESPECIALLY ACROSS SOUTHEASTERN NEW ENGLAND FRIDAY NIGHT AND
SATURDAY. SOME URBAN AND POOR DRAINAGE FLOODING CAN BE EXPECTED.

THE FORECAST TRACK AND DETAILS REGARDING THE IMPACTS OF OPHELIA
SHOULD CONTINUE TO BE MONITORED CLOSELY. PLEASE STAY TUNED TO
NOAA ALL HAZARDS WEATHER RADIO OR YOUR LOCAL MEDIA FOR UPDATED
INFORMATION.
