River Flood Warning 5, NWS Boston/Norton, MA

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE TAUNTON MA
1203 PM EST THU FEB 25 2010

.SYNOPSIS...
LOW PRES OFF THE CAROLINAS WHICH BECOMES AN INTENSE STORM AS IT
CURLS N AND THEN W ACROSS LONG ISLAND TONIGHT TO BE NEAR NEW YORK
CITY FRI MORNING. THEREAFTER...IT WEAKENS AND MEANDERS IN AND NEAR
SOUTHERN NEW ENGLAND THROUGH SAT BEFORE RE-ENERGIZING SUN INTO MON AS
STRONG OCEAN STORM EAST OF CAPE COD. MULTIPLE HAZARDOUS WEATHER
ELEMENTS WILL OCCUR IN SOUTHERN NEW ENGLAND WITH THIS LONG DURATION
STORMY PERIOD TODAY THROUGH THE WEEKEND.

&&

.NEAR TERM /UNTIL 4 PM THIS AFTERNOON/...
LOW PRESSURE WILL CONTINUE TO RAPIDLY DEVELOP TODAY WELL SOUTH OF
LONG ISLAND. BY LATE TONIGHT OR EARLY TOMORROW MORNING THE SFC LOW
WILL LIKELY BE LOCATED IN THE VICINITY OF LONG ISLAND OR CONNECTICUT
WITH A MSLP OF BETWEEN 970 AND 975MB. THIS WILL BE A WARM SYSTEM FOR
MUCH IF NOT ALL OF SOUTHERN NEW NEW ENGLAND THROUGH THE REST OF TODAY
AND INTO A GOOD PORTION OF TONIGHT...THEREFORE WE ARE NOT EXPECTING
MUCH IN THE WAY OF WINTRY PRECIPITATION. HOWEVER...THERE CONTINUES TO
BE A MULTITUDE OF POTENTIAL HAZARDS...INCLUDING WIND...FLOODING...AND
COASTAL FLOODING. WE ARE THINKING ANOTHER 1 TO 2 INCHES OF RAINFALL
WILL OCCUR ACROSS MUCH OF SOUTHERN NEW ENGLAND THROUGH TONIGHT WITH
LOCALIZED AMOUNTS OF 2.5 TO 3 INCHES...MAINLY ACROSS SOUTHERN NH AND
NORTH-CENTRAL AND NORTHEAST MASS.

WINDS MAY START BECOMING AN ISSUE LATE THIS AFTERNOON...BUT SHOULD BE
MORE OF AN ISSUE THIS EVENING INTO THE OVERNIGHT HOURS...ESPECIALLY
ALONG THE NORTHEAST COAST OF MASS. HOWEVER...WIND ADVISORIES MAY NEED
TO BE ISSUED AREA-WIDE DUE TO THE STRONG PRESSURE GRADIENT AND
ANOMALOUS EASTERLY LOW LEVEL JET. STILL THINKING DAMAGING 50 KT
GUSTS ALONG THE COAST COAST OF MASS THIS EVENING...WITH THOSE SPEEDS
ALSO POSSIBLE ACROSS HIGHER ELEVATIONS ACROSS THE NORTHERN PORTION
OF THE CWA AS WELL. WILL HAVE TO CONSIDER ADDITIONAL HEADLINES.

ALSO CONCERNED ABOUT ADDITIONAL SNOWFALL IN THE HIGHER ELEVATIONS OF
THE BERKSHIRES TONIGHT. WE HAVE HAD SOME RECENT REPORTS OF SNOW
FALLING AT THE HIGHER ELEVATIONS THIS MORNING BUT WE THINK THE COLUMN
WILL WARM TODAY AND PRECLUDE ANY ADDITIONAL SIGNIFICANT ACCUMS.
HOWEVER...WITH CAA OCCURRING TONIGHT WE MAY HAVE TO PUT UP SOME SORY
OF HEADLINE FOR UPSLOPE SNOWS.

WE HAVE NOW POSTED A COASTAL FLOOD ADVISORY FOR THIS EVENINGS HIGH
TIDE...AND A COASTAL FLOOD WATCH FOR FRIDAY MORNINGS HIGH TIDE.

&&

.SHORT TERM /4 PM THIS AFTERNOON THROUGH 6 AM FRIDAY/...
PREVIOUS DISCUSSION...

LOW PRESSURE EXPECTED TO STRENGTHEN TONIGHT. HEAVIEST RAINFALL OCCURS
THIS EVENING. ALL MODELS ADVERTISING THE ENTRAINMENT OF SOME DRY AIR
ACROSS EASTERN MA AND RI LATE TONIGHT...TEMPORARILY BRINGING AN END
TO THE RAIN. THIS SEEMS REASONABLE GIVEN THE STRENGTH OF THIS LOW
PRESSURE.

TEMPERATURES START TO DROP LATE TONIGHT. THIS SHOULD BE JUST ENOUGH
TO SWITCH FORM RAIN TO SNOW ACROSS THE HIGHER TERRAIN OF CENTRAL AND
WESTERN MA...AS WELL AS SOUTHWEST NH.

&&

.LONG TERM /FRIDAY THROUGH WEDNESDAY/...
THE MAIN FOCUS OF THE LONG TERM PORTION OF THE FORECAST WAS ON THE
FRIDAY THROUGH MONDAY TIMEFRAME.  IT IS DEFINITELY A COMPLICATED
FORECAST WITH SEVERAL SLIGHTLY DIFFERENT SOLUTIONS THROUGH SUNDAY
MORNING.  FOR THIS TIME PERIOD...THE 00Z SUITE OF MODELS HAVE THE
SAME BASIC UPPER LEVEL AND SURFACE PATTERNS BUT WITH SEVERAL
DIFFERENT TRACKS.  THIS WILL AFFECT THE DETAILS OF THE EVENT...
PTYPE...WIND DIRECTION AND STRENGTH...QPF.  THE 00Z GEFS IS
CLUSTERED MOST CLOSELY WITH THE 00Z GGEM/ECMWF SOLUTION WITH REGARDS TO
PLACEMENT OF THE UPPER LOW AND WITH THE 00Z GFS FOR THE SURFACE
REFLECTION.

AN UPPER LEVEL LOW OVER THE NYC METRO AREA SHIFTS AROUND BETWEEN NYS
AND SOUTHERN NEW ENGLAND WHILE THE SURFACE REFLECTION DOES MUCH THE
SAME THING.  AS MENTIONED ABOVE...HAVE A COUPLE DIFFERENT SOLUTIONS
IN REGARDS TO WHICH DIRECTION THEY SHIFT.  THIS WILL BRING PERIODS
OF PRECIPITATION TO THE AREA THROUGH SATURDAY.  LOW CONFIDENCE IN
PTYPE AND COVERAGE OF PRECIPITATION.  HOWEVER...GENERALLY RAIN ALONG
THE COAST WITH SNOW OR A MIX OF RAIN AND SNOW ACROSS THE FAR NW
INTERIOR HIGH TERRAIN.  EXACTLY WHERE THE RAIN/SNOW LINE WILL BE IS
TOUGH TO DETERMINE AT THIS POINT.

SUNDAY AND MONDAY...ANOTHER LOW PRESSURE SYSTEM DEVELOPS OFF THE
SOUTHEAST U.S. COAST.  THIS SYSTEM MOVES NORTHWARD BUT REMAINS FAR
OUT TO SEA...APPROACHING SOUTHERN NEW ENGLAND WELL EAST OF THE 40/70
BENCHMARK.  THERE DOES APPEAR TO BE AN INVERTED TROUGH WITH THIS
SYSTEM THAT MAY BRING ANOTHER ROUND OF PRECIPITATION TO SOUTHERN NEW
ENGLAND.  HOWEVER...THIS MODEL RUN MAY BRING THE LOW FAR ENOUGH
OFFSHORE THAT IT MAY HAVE LITTLE EFFECT.  THE SYSTEM AT THE END OF
THIS WEEK AND ITS DEPARTURE WILL HAVE AN IMPACT ON WHAT THIS NEXT
SYSTEM DOES AND WHAT IMPACT IT HAS ON THE REGION.

EXPECT GENERALLY DRIER CONDITIONS TUESDAY AND WEDNESDAY.

&&

.AVIATION /17Z THURSDAY THROUGH MONDAY/...
PLEASE SEE 12Z TAFS AND ANY OF THEIR AMENDMENTS FOR DETAILS.

HIGH CONFIDENCE IN MAINLY IFR CONDITIONS THROUGH THE PERIOD ...WITH
PERIODS OF LIFR CONDITIONS IN FOG AND DRIZZLE EARLY THIS MORNING
BECOMING PERIODIC RAINS BY LATE THIS MORNING THROUGH THIS EVENING
AND SOMEWHAT IMPROVING IFR CONDS.

HEAVIEST RAIN SQUALLS OCCUR LATE THIS AFTERNOON OR EVENING AS LLWS
DEVELOPS WITH AN INTENSE STORM FIRST MOVING DUE N TOWARD NANTUCKET
THEN ABRUPTLY CURLING WEST TONIGHT THROUGH LONG ISLAND SOUND.

SUBSTANTIAL LLWS IS THE FCST.

ELY GUSTS 35-45 KTS EXPECTED AT KBOS/KHYA/KACK/KFMH BETWEEN 22Z AND
05Z WITH INLAND GUSTS AT KORH/KMHT/KPVD POSSIBLE REACHING 30-40KT FOR
AN HOUR OR 2 WITHIN THE 01Z-06Z TIME FRAME.

CONDITIONS LIKELY WILL IMPROVE TO MVFR CIGS THROUGHOUT THE AREA
BETWEEN 06Z AND 12Z FRIDAY WITH BRIEF S GUSTS 33-40 KTS KACK/KHYA/KFMH
08Z-13Z FRI. HOWEVER...PERIODS OF MVFR OR BRIEF IFR IN SNOW SHOWERS
MAY DEVELOP BY 12Z FRI IN KBAF/KBDL.

OUTLOOK...FRIDAY THROUGH MONDAY...

FRIDAY...MVFR/IFR CONDITIONS LIKELY IN RAIN/SNOW MIX CHANGING TO
SNOW OVERNIGHT.  PATCHY FOG POSSIBLE.  ACCUMULATING SNOW POSSIBLE
OVERNIGHT...PARTICULARLY NW HIGH TERRAIN.

SATURDAY...MVFR/IFR CONDITIONS LIKELY IN SNOW WITH BRIEF PERIODS OF
RAIN ON THE EAST COAST.  PATCHY FOG POSSIBLE. ACCUMULATING SNOW
POSSIBLE ACROSS THE AREA.

SUNDAY...MVFR/IFR CONDITIONS LIKELY IN SNOW WITH BRIEF PERIODS OF
RAIN ON THE EAST COAST.  PATCHY FOG POSSIBLE.  ACCUMULATING SNOW
POSSIBLE ACROSS THE AREA.  N/NW WINDS MAY GUST TO 25 TO 30 KTS ON
THE CAPE AND ISLANDS.

MONDAY...MVFR/IFR CONDITIONS IMPROVING AS PRECIPITATION MOVES TO THE
COAST AND THEN OUT TO SEA.  N/NW WINDS MAY GUST TO 25 TO 30 KTS ON
THE CAPE AND ISLANDS.

&&

.MARINE...
INCREASING WINDS AND SEAS THROUGH TODAY...WITH EAST GALES EXPECTED
BY EARLY THIS EVENING ACROSS THE WATERS. STORM WARNINGS HAVE BEEN
POSTED FOR A PORTION OF THE MARINE FORECAST AREA...MAINLY OUR
NORTHEAST WATERS AS 50 TO 60 KT GUSTS WILL BE POSSIBLE THIS EVENING.
WINDS EXPECTED TO DIMINISH TO SMALL CRAFT ADVISORY LEVELS LATE
TONIGHT. HOWEVER...VERY ROUGH SEAS WILL CONTINUE. WE HAVE FORECASTED
25 FT SEAS ON STELLWAGEN BANK TONIGHT...AND IT/S POSSIBLE THEY COULD
GO HIGHER THAN THAT.

OUTLOOK...FRIDAY THROUGH MONDAY...

FRIDAY...WINDS FALL BELOW SMALL CRAFT CRITERIA BUT SEAS...THOUGH
SLOWLY DIMINISHING...WILL REMAIN WELL ABOVE 5 FEET THROUGH THE DAY.
SEAS ARE EXPECTED TO BE IN THE 5 TO 10 FT RANGE NEAR THE COAST AND 8
TO 15 FT RANGE ON THE OUTER WATERS.

SATURDAY...SMALL CRAFT CONDITIONS.  SEAS CONTINUE TO DIMINISH...
REMAINING ABOVE 5 FEET.  WINDS GENERALLY E/SE AT 10 TO 20 KT.

SUNDAY...SMALL CRAFT CONDITIONS.  SEAS DIMINISH FOR A TIME SUNDAY
AFTERNOON AND THEN INCREASE AS LOW PRESSURE NEARS THE NEW ENGLAND
WATERS.  E WINDS SHIFT TO N/NW AND THEN INCREASE TO 20 TO 30 KT.

MONDAY...SMALL CRAFT CONDITIONS.  SEAS INCREASE AS OCEAN STORM
INTENSIFIES AND MAKES ITS CLOSEST PASS TO NEW ENGLAND.  LOW
PROBABILITY OF GALES ON THE EASTERN WATERS.  NW WINDS GUSTING TO 25
KTS OR MORE.

&&

.HYDROLOGY...
FLOOD WATCH CONTINUES FOR THE MAJORITY OF SOUTHERN NEW ENGLAND.
FLOOD WARNING CONTINUES FOR THE PAWTUXET RIVER AT CRANSTON. IT IS
POSSIBLE THAT RIVER FLOOD WARNINGS MAY BE POSTED THIS AFTERNOON FOR
SOME MERRIMACK TRIBUTARIES PENDING LATEST GUIDANCE FROM NERFC.

LIGHT TO MODERATE RAIN IS EXPECTED TO INCREASE IN INTENSITY DURING
THIS AFTERNOON AND EVENING. THE COMBINATION RAIN/SNOW EVENT FROM
TUESDAY NIGHT INTO WEDNESDAY HAS LEFT THE AREA VULNERABLE TO
FLOODING. IN THE EAST...GENERAL 1.5 TO 2.5 INCHES OF RAIN PUSHED UP
STREAMS AND RIVERS. TO THE WEST...A WATER LADEN SNOWPACK BRINGS THE
POTENTIAL FOR MELT.

A TOTAL RAINFALL OF 1 TO 2 INCHES IS STILL EXPECTED ACROSS THE AREA
FOR TODAY AND TONIGHT.  SCATTERED TOTALS TO 3 INCHES ARE POSSIBLE IN
NORTHEAST MASSACHUSETTS INTO SOUTH CENTRAL NEW HAMPSHIRE. LATEST
GRIDDED QPF REFLECTS THIS.

EXACT FFG VALUES ARE DIFFICULT TO PINPOINT. THIS IS BECAUSE WHILE
THE TOPMOST FEW INCHES OF SOIL ARE THAWED...BELOW THAT THE SOIL IS
FROZEN. THIS PRESENTS A CHALLENGE SINCE MUCH OF THE RAIN/SNOWMELT
WOULD BECOME RUNOFF. THE ABOVE MENTIONED FORECAST RAIN AND SNOWMELT
IS EXPECTED TO BE SUFFICIENT TO PRODUCE FLOODING WITHIN THE WATCH AREA.

A CAVEAT IS THAT OVER THE HIGHER TERRAIN OF CHESHIRE COUNTY AND THE
EAST SLOPES OF THE BERKSHIRES...SOME OF THE RAIN COULD BE ABSORBED
BY THE SNOWPACK. BUT NOTING LATEST STREAM GAGE DATA IN SOUTHWEST NH
AND THE EAST SLOPES OF THE BERKSHRIES...AT LEAST SOME STREAM
RESPONSES HAVE BEEN NOTED...SO RUNOFF IS OCCURRING. SNOW CLOGGED
DRAINS COULD ALSO CAUSE FLOODING ISSUES.

CALLS MADE YESTERDAY TO LOCAL OFFICIALS IN THE FAR INTERIOR INDICATE
THAT RIVER ICE IS LESS THAN TYPICAL FOR THIS TIME OF YEAR...
GENERALLY AWAY FROM PONDS THERE ARE GOOD OPEN AREAS ALONG STREAMS
AND RIVERS...OR THEY ARE WIDE OPEN. SO BASED ON THIS
INFORMATION...ICE JAM FLOODING IS NOT ANTICIPATED IN SOUTH
CENTRAL/SOUTHWEST NH AND FAR INTERIOR MA.

&&

.TIDES/COASTAL FLOODING...
ASTRO HIGH TIDE IS RELATIVELY LOW THIS EVENING...BUT ONSHORE WINDS
WILL BE INCREASING TO STORM FORCE LEVELS AND SEAS BUILDING
DURING THE EVENING. THE ONSHORE WIND DRIVING LARGE SEAS ONSHORE WILL
INCREASE THE SURGE ALONG THE EAST COAST TO BETWEEN 2 AND 3 FEET
ACCOMPANIED BY POUNDING SURF. THUS...HAVE CONVERTED THE COASTAL
FLOOD WATCH TO A COASTAL FLOOD ADVISORY FOR THIS EVENING. COULD BE
FAIRLY WIDESPREAD MINOR COASTAL FLOODING...AND THERE IS A RISK OF A
FEW SPOTS REACHING MODERATE COASTAL FLOOD CRITERIA...DUE TO WAVE
DRIVEN WAVES CRASHING ONSHORE. WILL NEED TO MONITOR...IN THE EVENT
THAT THE WINDS AND SEAS RISE FASTER THAN PREDICTED IN WHICH CASE WE
WOULD HAVE TO UPGRADE TO A WARNING.

ISSUED A COASTAL FLOOD WATCH FOR THE FRIDAY MORNING HIGH TIDES ON
BOTH THE EAST AND SOUTH COASTS. ALONG THE EAST COAST...THE SURGE MAY
REACH 3 TO 3.5 FEET DURING THE NIGHT BUT IS EXPECTED TO BE RELAXING
DOWN TO BETWEEN 1 AND 2 FEET AROUND THE TIME OF THE 8 TO 9 AM HIGH
TIDE. THINK THAT THE MRPSSE GUIDANCE IS RELAXING THE SURGE TOO
QUICKLY AND HAVE GONE ABOVE. TWO OTHER FACTORS MAKE THIS A
POTENTIALLY WIDESPREAD MODERATE COASTAL FLOOD EVENT. IT IS A
RELATIVELY HIGH ASTRONOMICAL HIGH TIDE AND EXPECT SEAS TO STILL BE
NEAR 20 FEET JUST OFFSHORE...WITH A LARGE HIGH ENERGY SWELL
COMPONENT.

HAVE ALSO ISSUED A COASTAL FLOOD WATCH FOR THE SOUTH COAST WHERE
SURFACE WINDS ARE PROGGED TO SHIFT TO A SOUTHERLY COMPONENT DURING
THE EARLY MORNING HOURS. THIS COMBINED WITH LOW SURFACE PRESSURE MAY
PRODUCE A STORM SURGE OF 2 TO 3 FEET...POSSIBLY EVEN HIGHER FOR THE
UPPER PART OF NARRAGANSETT BAY.

AS WE HAVE BEEN NOTING...BEACH EROSION IS A CONCERN FOR AT LEAST THE
NEXT SEVERAL HIGH TIDE CYCLES...MAINLY ALONG THE EAST COAST OF
MASSACHUSETTS WITH A PARTICULAR CONCERN ALONG THE NEWBURYPORT TO
GLOUCESTER STRETCH. THE ACCUMULATIVE IMPACT OF SUCCESSIVE HIGH TIDE CYCLES
WITH BEACH EROSION...ENHANCED BY A LONG DURATION OF WAVES WITH A HIGH
SWELL ENERGY COMPONENT...IS IN ITSELF A SIGNIFICANT CONCERN.
