AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE TAUNTON MA
1244 PM EST FRI FEB 27 2009
.SYNOPSIS...
LOW PRESSURE OVER LAKE HURON EARLY THIS MORNING DRIVES A COLD FRONT
ACROSS OUR AREA LATE TONIGHT AS THE LOW REACHES THE MARITIMES. STRONG
COLD HIGH PRESSURE BUILDS INTO QUEBEC SATURDAY SETTING THE STAGE FOR
ONE...IF NOT TWO...COASTAL LOW PRESSURE SYSTEMS TO BRING VARYING AMOUNTS
OF WINTRY PRECIPITATION TO OUR AREA BETWEEN EARLY SUNDAY AND TUESDAY
NIGHT. DRY HIGH PRESSURE SLOWLY BUILDS INTO NEW ENGLAND NEXT WEDNESDAY
AND THURSDAY.
&&
.NEAR TERM /UNTIL 6 PM THIS EVENING/...
DECIDED TO GO WITH A MARGINAL WIND ADVISORY INTO THE EARLY EVENING
HOURS FOR PORTIONS OF RHODE ISLAND AND INTERIOR SOUTHEAST MA. THIS
AREA HAS SEEN TEMPERATURES WARM TO AROUND 60 DEGREES AND SHOULD
ALLOW FOR SLIGHTLY BETTER MIXING THAN DEPICTED BY THE SOUNDINGS.
ITS MARGINAL...BUT SINCE ITS NEAR TERM FIGURED IT WAS WORTH IT.
PREVIOUS DISCUSSION FROM 1039 AM:
SKIES HAVE BECOME PARTLY SUNNY ACROSS EASTERN MA/RHODE ISLAND LATE
THIS MORNING...BUT THERE WERE STILL PLENTY OF LOW CLOUDS ACROSS
NORTHWEST MA/SOUTHERN NH. THESE CLOUDS MAY LIFT A BIT THIS
AFTERNOON...BUT THEY WILL BE REPLACED BY PLENTY OF MID LEVEL AND
DIURNAL CLOUDINESS. THEREFORE...GENERALLY EXPECT MOSTLY CLOUDY
SKIES IN THE DISTANT INTERIOR THROUGH THE AFTERNOON. ACROSS EASTERN
MA/RHODE ISLAND SKIES SHOULD BE PARTLY SUNNY THROUGH THE AFTERNOON.
IT WILL BE AN UNSEASONABLY MILD DAY WITH 850 MB TEMPERATURES BETWEEN
+4C AND +5C. HIGH TEMPERATURES SHOULD RANGE FROM THE UPPER 40S TO
LOWER 50S ACROSS THE INTERIOR HIGH TERRAIN...TO THE UPPER 50S TO
NEAR 60 ACROSS EASTERN MA/RHODE ISLAND WHERE THERE IS MORE IN THE
WAY OF SUNSHINE.
AS THE PREVIOUS FORECAST MENTIONED...THERE IS A FAIRLY STRONG LOW
LEVEL JET BETWEEN 55 AND 65 KNOTS. HOWEVER...AN ABUNDANCE OF CLOUDS
AND AN INVERSION SHOULD KEEP MOST LOCATIONS ACROSS THE INTERIOR
BELOW WIND ADVISORY CRITERIA. HOWEVER...WE HAVE POSTED A MARGINAL
WIND ADVISORY FOR PORTIONS OF RHODE ISLAND AND INTERIOR SOUTHEAST
MA. THIS IS WHERE TEMPERATURES HAVE WARMED TO 60 AND SHOULD YIELD
SLIGHTLY BETTER WINDS THAN BUFKIT PROJECTS.
AS FOR PRECIPITATION...RELIED ON THE SREF POPS WHICH SEEM TO MATCH UP
WELL WITH THE LATEST OPERATIONAL GUIDANCE. IT SHOULD REMAIN DRY
THROUGH THE MORNING WITH THE DYNAMICS AND LIFT AHEAD OF THE COLD
FRONT WELL TO OUR WEST. WILL BRING IN SOME CHANCE POPS ACROSS THE
INTERIOR DURING THE MID/LATE AFTERNOON HOURS. WE WILL THEN QUICKLY
INCREASE POPS IN OUR INTERIOR TO CATEGORICAL BETWEEN 22Z AND 00Z.
ACROSS THE COASTAL PLAIN...EXPECT IT TO REMAIN DRY THROUGH THE
AFTERNOON AND WILL JUST BRING IN SOME 15 TO 20 POPS AROUND 00Z.
&&
.SHORT TERM /6 PM THIS EVENING THROUGH 6 PM SATURDAY/...
TONIGHT...COLD FRONT CROSSES THE AREA. CATEGORICAL POPS FOR SHOWERS.
USED A BLEND OF MAVMOS AND MOSGUIDE TEMPS FOR OVERNIGHT LOWS.
SATURDAY...HIGH PRESSURE ATTEMPTS TO BUILD FROM THE NORTH. HOWEVER
IT APPEARS THE COLDER AIR JUST OOZES SOUTH AND MAY NOT FULLY ARRIVE
UNTIL NIGHTFALL. GIVEN SOME DOWNSLOPING NNW FLOW AND LACK OF ACCOUNT
OF THIS LOW LEVEL COLD AIR...HAVE DECIDED TO USE A 50/50 BLEND OF
RAW GFS 2M AND MAVMOS GUIDANCE FOR HIGHS.
&&
.LONG TERM /SATURDAY NIGHT THROUGH THURSDAY/...
UNCERTAINTY CONTINUES IN THE MODEL GUIDANCE...BUT ENOUGH INFORMATION
AVAILABLE TO COUNT ON ONE IF NOT TWO SIGNIFICANT COASTAL LOWS BETWEEN
SUNDAY AND TUESDAY NIGHT.
THE ESSENTIAL MESSAGE...BE PREPARED FOR FOR POSSIBLE TRAVEL DELAYS
DUE TO SNOW...SLEET AND FREEZING RAIN /EXCEPT SNOW SLEET RAIN OR
FREEZING RAIN CAPE COD AND ISLANDS/.
00Z/27 OP GGEM/ECMWF ARE IMPRESSIVE. UK IS EASTERN OUTLIER AS IS THE
00Z GFS. GEFS WAS MORE ROBUST AND WE RODE THAT PLUS THE GGEM/WAFFLING
ECMWF AND GENERALLY SIGNIFICANT SREF. 00Z GEFS WAS COHERENT ON AN
EVENT SUNDAY...PROBABLY A MODERATE EVENT. SREF HAS MORE VARIABILITY
EMBEDDED BUT IT TOO IS ROBUST AND NOT SLIDING EAST LIKE THE UK.
THE WAFFLING OF THE MODELS INDICATES THE DELICATE INTERACTIONS OF
NORTHERN/SOUTHERN STREAMS AND I CAN EASILY SEE MODEL SHIFTING BACK
TO THE WEST FOR BOTH SYSTEMS IN FUTURE MODEL CYCLES. THIS FORECAST HELD
FIRM ON THE POPS FOR SUNDAY AND BEYOND...ACTUALLY INCREASING POPS DUE
TO RETURN OF THE ECMWF.
NCEP ENSEMBLES /BOTH SREF AND GFS/ HAVE BEEN FOR FAR TOO LONG
PREDICTING AT LEAST ONE MODERATE SNOW/ICE EVENT FOR OUR AREA AND I
SEE NO REASON TO FADE.
THE DAILIES...
SAT NIGHT...BLENDED SLOWER ON POPS AND ONSET OF WINTRY PCPN. YET THE
06Z GFS IS FASTER.
SUN...BLENDED PARTIAL THICKNESSES OF THE 00Z/NAM AND GFS TO MAINTAIN
AN ICE COMPONENT IN THIS FCST. THE 00Z GFS OP RUN APPEARS TO BE A
COLD AND DRY OUTLIER. AFTER REVIEW OF THE SREF/GFS ENS AS WELL AS
NEW 00Z EC/UK/GGEM...WE CONTINUED WITH A TOTALED LIGHT TO MODERATE
EVENT SUNDAY. HIGHLY PROBABLE SEVERAL INCHES OF SNOW OR SNOW/SLEET
COMBINED SUNDAY.
DECENT RRQ OF THE UPPER LVL JET SHOULD BE A PRIMARY NEWD DRAW OF THE
FIRST EVENT WITH 700/850 JET CORES FOCUSING QPF ON SNE. FGEN MODEST.
DONT HAVE CONFIDENCE ON THE SLEET BOUNDARY DUE TO WHAT IN MY OPINION
WAS AN OUTLIER COLD DRY GFS SOLN.
SUN NIGHT...THIS IS WHERE WE SUBSTANTIVELY UPGRADE QPF FROM HPC PLUS
POPS FROM SREF AND GEFS. CONFIDENCE ON THIS IS AVERAGE. I SORT OF
THINK THIS OCCURS FASTER ON SUNDAY OR DELAYS TIL MONDAY.
NO MATTER...WHEN THE SNOW TOOL IS CONSERVATIVELY TOTALED FOR SUN AND
SUN NIGHT...WE GET 1 TO 4 INCHES S NH NW MASS AND HFD COUNTY WITH 4
TO 7 INCHES NE MASS TO NE CT INCLUDING NRN RI AND MUCH OF INTERIOR SE
MASS. PLACEMENT OF THIS HEAVIER SNOW AXIS MAY BE IN ERROR DUE TO
PARTIAL THICKNESS CONSIDERATIONS AND...THE I 95 CORRIDOR SEWD PTN
MAY BE SLEET INSTEAD OF SNOW. STRONG LIKELIHOOD OF ADVISORY IN THE
SUNDAY TIME FRAME.
MON-TUE...DEFERRED TO MUCH GREATER UNCERTAINTY...ONLY BECAUSE OF THE
EWD UK AND DIVERGENT GFS ENS MEMBERS...BUT EVEN HERE... SEEMS LIKE
THE MODELS WANT TO DRIFT THIS UPPER LOW UP THE COAST. THIS COULD BE
AN IMPRESSIVE ONE TWO PUNCH HERE IN COASTAL SE NEW ENGLAND.
POPS WERE INCREASED. THERE IS SIGN OF SOME SORT OF BLOCKING IN ERN
CANADA AND I THINK WE NEED BE VIGILANT ABOUT A VERY WINTRY WEEK OF
WEATHER HERE IN ERN MASS AND RI.
WED-FRI GRIDS...ADJUSTED A BIT WITH MOS BUT DID LITTLE EFFORT HERE
ENCOURAGING OUR FOLLOWING DAY SHIFT TO IMPROVE THE DETAIL. ADDED
CLOUD THURSDAY DUE TO UPPER LOW. MADE NO POP CHANGES ATTM-NO TIME TO
EVALUATE.
&&
.AVIATION /16Z FRIDAY THROUGH TUESDAY/...
TODAY...LIFR/IFR IN LOW CLOUDS AND FOG PATCHES ACROSS THE INTERIOR
THIS MORNING. THESE CONDITIONS SHOULD IMPROVE TO MARGINAL MVFR/VFR
IN THIS REGION...BUT STILL EXPECT A BROKEN DECK OF CLOUDS.
OTHERWISE...VFR CONDITIONS EXPECTED ON THE COASTAL PLAIN. SCATTERED
SHOWERS WILL BEGIN TO AFFECT THE INTERIOR IN THE MID/LATE
AFTERNOON...BUT WILL BECOME WIDESPREAD BY 00Z. IN ADDITION...WIND
GUSTS OF 25 TO 35 KNOTS SHOULD DEVELOP THIS AFTERNOON...WITH THE
STRONGEST GUSTS EXPECTED AT ORH/BOS/PVD.
TONIGHT...WIDESPREAD MVFR WITH AREAS IFR/LIFR CEILINGS IN SHOWERS
AND FOG PATCHES. COLD FROPA EXPECTED BETWEEN 04Z AND 09Z. LLWS
ADDED TO THE FMH HYA AND ACK TAFS AT 12Z.
SATURDAY...VFR. HIGH PRESSURE SETTLES OVERHEAD WITH NNW FLOW
BECOMING NE.
OUTLOOK /SATURDAY NIGHT THROUGH TUESDAY/...
SATURDAY NIGHT...VFR THROUGH 04Z THEN MVFR/IFR CONDS DEVELOP IN
SNOW/SLEET/FREEZING RAIN BOS TO PVD SEWD NEAR OR JUST MIDNIGHT /05Z/.
SUNDAY...MVFR/IFR CONDITIONS IN MAINLY SNOW AND SLEET....ESP BOS-PVD
SEWD. CHANCE ONLY VFR CIGS MHT BAF REGION IN.
SUNDAY NIGHT THROUGH TUESDAY...STILL UNCERTAIN ON THE DETAILS-PERIODS
OF MVFR/IFR IN SNOW/SLEET...HOWEVER...ENOUGH INFORMATION TO INDICATE
THAT ANOTHER 12 TO 24 HOUR PERIOD OF ADVERSE AVN CONDS IS EXPECTED...AT
LEAST FOR CAPE COD AND QUITE POSSIBLY ALL LOCATIONS BDL-MHT SEWD.
&&
.MARINE...
TODAY...SMALL CRAFT ADVISORY WITH GUSTY SOUTHWEST WINDS DEVELOPING
IN THE LATE MORNING AND ESPECIALLY THE AFTERNOON. LOW LEVEL
INVERSION WILL CAP WINDS IN THE 25 TO 30 KT RANGE...PERHAPS
SCATTERED GUSTS UP TO 35 KT NEAR SHORE THIS AFTERNOON. WE BUMPED UP
SEAS TO BETWEEN 4 AND 5 FEET ACROSS NARR BAY AND VINEYARD SOUND...AS
GUSTY SOUTHWEST WINDS OFTEN CREATES CHOPPY SEAS IN THIS REGION.
OTHERWISE...SEAS MAY BE A BIT OVER DONE ACROSS THE OUTER-WATERS WITH
AN INVERSION.
TONIGHT...COLD FRONT PASSES THROUGH THE AREA. WINDS SHIFT TO THE NW.
HAZARDS SEAS REMAIN DUE TO SOUTHWEST SWELL. ADJUSTED WAVE HEIGHTS BY
UNDERCUTTING 15 PERCENT.
SATURDAY...HIGH PRESSURE SETTLES OVER THE WATERS. A SMALL CRAFT
ADVISORY MAINLY FOR HAZARDOUS SEAS PERSIST ACROSS THE OUTER WATERS.
OUTLOOK /SATURDAY NIGHT THROUGH TUESDAY/....
SATURDAY NIGHT THROUGH TUESDAY...STRONG SCA TO PERIODS OF MARGINAL
GALE FORCE NORTHEAST WIND GUSTS AT TIMES. HIGH PRESSURE OVER EASTERN
CANADA AND WAVES OF LOW PRESSURE TO THE SOUTH...WILL CREATE
PERSISTENT NORTHEAST WINDS AND RELATIVELY HIGH SEAS OVER THE OUTER
WATERS.
WNA MODEL LIKELY IS UNDER DONE WITH SEAS WITH THE CONSTANT NORTHEAST
FLOW. BLENDED ALL AVBL GUIDANCE SEAS AOA THE PREVIOUS 4PM THURSDAY
FCST TO KEEP RUNNING SEAS HIGHER. A LONG ROUGH STRETCH FOR MARINE
INTERESTS.
STILL A LOW PROBABILITY OF STORM FORCE WIND GUSTS OVER THE OPEN WATERS
MON/TUE. LOWERED GUSTS 2 TO 6 KNOTS FROM THE GFS GUST ALG.
&&
.TIDES/COASTAL FLOODING...
PERSISTENT NORTHEAST FLOW MAY RESULT IN SOME BEACH EROSION ON NORTH
AND EAST FACING BEACHES SUNDAY INTO TUESDAY. HOWEVER...AT THIS POINT THE
THREAT FOR ANY COASTAL FLOODING APPEARS LOW.
