AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE TAUNTON MA
900 AM EDT THU MAR 12 2009

.SYNOPSIS...
HIGH PRESSURE WILL START TO BUILD ACROSS SOUTHERN NEW ENGLAND
TODAY...AND DOMINATE OUR WEATHER INTO SATURDAY. A WEAK COLD FRONT
SHOULD MOVE SOUTH ACROSS OUR REGION EARLY SUNDAY...FOLLOWED BY
ANOTHER HIGH PRESSURE FROM EASTERN CANADA FOR EARLY NEXT WEEK. A LOW
PRESSURE ALONG THE MID ATLANTIC COAST MAY BECOME A LATE WINTER STORM
FOR OUR REGION SOMETIME TUESDAY OR WEDNESDAY.

&&

.NEAR TERM /UNTIL 6 PM THIS EVENING/...
GUSTY NORTHWEST WINDS STILL CONTINUING THIS MORNING...BUT SHOULD
START TO DIMINISH SOON AS BEST PRESSURE RISES SETTLE ACROSS THE GULF
OF MAINE.

HIGH PRES RIDGE WILL BUILD E OUT OF THE GREAT LAKES...KEEPING OUR
REGION IN A COOL...DRY NW FLOW AT THE SURFACE AND ALOFT. WINDS MAY
BECOME A BIT BLUSTERY LATE THIS MORNING AND AFTERNOON WITH H85 TEMPS
CONTINUING TO DROP DURING THE DAY. WILL ALSO SEE SOME FAIR WEATHER
CLOUDS DEVELOP...THOUGH NOT EXPECTING A WHOLE LOT OF THOSE. ONLY
PROBLEM COULD BE LAKE EFFECT CLOUDS WORKING OUT OF E NY STATE INTO
THE BERKSHIRES AND MONADNOCKS...THOUGH ENOUGH SUBSIDENCE MAY KEEP
THOSE CLOUDS AT BAY.

WITH THE COLD AIR CONTINUING TO FILTER INTO THE REGION...TEMPS WILL
ONLY RISE TO THE MID 30S TO LOWER 40S...5 TO 10 DEGREES BELOW
SEASONAL NORMS. WILL FEEL COLDER WITH THE GUSTS...MAINLY THIS
MORNING.

&&

.SHORT TERM /6 PM THIS EVENING THROUGH 6 PM FRIDAY/...
TONIGHT...HIGH BECOMES ESTABLISHED OVER THE NORTHEASTERN
U.S...COLDEST AIR WILL BE OVER THE REGION WITH H85 TEMPS DOWN TO
BETWEEN -10C TO -15C. THIS...ALONG WITH MAINLY CLEAR SKIES AND LIGHT
WINDS WILL BE RECIPE FOR RADIATIONAL COOLING. EXPECTING OVERNIGHT
LOWS TO RUN MOSTLY IN THE TEENS...THOUGH A FEW PLACES COULD SEE
SINGLE DIGITS ACROSS THE INLAND VALLEYS. THIS IS AROUND 10 DEGREES
BELOW NORMAL FOR MID MARCH.

FRIDAY...SHORT RANGE MODELS SHOWING SOME TIMING DIFFERENCES IN
MOVING THE RIDGE OVER THE REGION. IN ANY EVENT...EXPECTING MAINLY
CLEAR SKIES ONCE AGAIN AS LIGHT WINDS MAY BECOME MORE SOUTHERLY BY
LATE IN THE DAY. COLD AIR AXIS DOES REMAIN OVER THE REGION...SO
STILL EXPECTING DAYTIME HIGHS MAINLY IN THE 30S...POSSIBLY AROUND 40
IN THE LOWER CT VALLEY.  THIS IS STILL 5 TO 10 DEGREES BELOW NORMAL.

&&

.LONG TERM /FRIDAY NIGHT THROUGH WEDNESDAY/...
MADE SOME CHANGES TO THIS PORTION OF THE FORECAST EARLY NEXT WEEK.
12/00Z MODELS ARE IN DECENT AGREEMENT THROUGH 12Z MONDAY.  AFTER
THAT TIME...THE DIFFERENCES IN THE MODEL SYNOPTICS START TO BECOME
SIGNIFICANT.  WENT WITH A DRIER FORECAST FOR MONDAY BASED UPON THE
OPERATIONAL GFS AND ECMWF PARKING A STRONG HIGH PRESSURE ACROSS
EASTERN CANADA.  12/00Z GGEM AND GEFS MEAN STILL ADVERTISE A WEAK
LOW PRESSURE...BUT THINKING THIS SYSTEM WILL PASS TOO FAR TO OUR
SOUTH TO IMPACT US MUCH MORE THAN WITH SOME CLOUDS.

TUESDAY INTO WEDNESDAY IS ANOTHER STORY.  CONFIDENCE IS AVERAGE THAT
THERE WILL BE A COASTAL LOW PRESSURE.  THE PROBLEM BECOMES WHERE
WILL IT GO.  LATEST 500 MB GUIDANCE SUGGESTS CONFLUENCE ZONE WILL
SHIFT EAST OFF THE COAST...WITH MORE OF A SPLIT ACROSS THE EASTERN
U.S..  12/00Z MODELS ARE TRYING TO PHASE TWO SHORTWAVE TROUGHS IN
THE TWO STREAMS...AND DEVELOP A UNIFIED MID LEVEL TROUGH OVER THE
EAST COAST.  IF THIS OCCURS...INSTEAD OF A WEAK LOW PRESSURE
SKIPPING OUT TO SEA IN THE SOUTHERN STREAM...WE COULD WIND UP WITH A
SIGNIFICANT LATE WINTER STORM.  CONFIDENCE ON THE DETAILS WITH THIS
SYSTEM ARE LOW.  SO MAINTAINED A CHANCE OF PRECIPITATION SOMETIME
BETWEEN TUESDAY AND WEDNESDAY.

&&

.AVIATION /13Z THURSDAY THROUGH MONDAY/...
TODAY...VFR CONDITIONS. MAY SEE SOME GUSTS CLOSE TO 25 KT UNTIL LATE
THIS AFTERNOON.

TONIGHT...VFR. WINDS BECOMING LIGHT.

FRIDAY...VFR.

OUTLOOK /FRIDAY NIGHT THROUGH MONDAY/...

FRIDAY NIGHT THRU MONDAY...VFR.

&&

.MARINE...
NOTE...WE HAVE 44020 IN ACK SOUND PROVIDING A NEW SOURCE OF BUOY
DATA.  THIS BUOY CAN BE FOUND ON THE NDBC WEBSITE.

TODAY...EXTENDED THE SMALL CRAFT THROUGH MID MORNING FOR MOST
LOCATIONS AS WIND GUSTS CONTINUE AT 25-30 KT. AS WINDS DIMINISH FROM
W-E...WILL BE ENDING SMALL CRAFT FOR MOST OF THE NEARSHORE WATERS BY
MIDDAY...KEEPING IT UP FOR THE OUTER WATERS THROUGH THE DAY. SEAS UP
TO 7-9 FT ON THE OUTER WATERS...AND WILL BE SLOW TO SUBSIDE.

TONIGHT...EXTENDED THE OUTER WATERS SMALL CRAFT THROUGH THE NIGHT...
MAINLY ON THE EASTERN WATERS AS SOME GUSTS TO 25 KT AND SEAS AOA 5
FT LINGER.

FRIDAY...EXPECT N WINDS AT 15 KT OR LESS WITH SEAS 4 FT OR LESS AS
HIGH PRES BUILDS ACROSS THE WATERS.

OUTLOOK /FRIDAY NIGHT THROUGH MONDAY/...

FRIDAY NIGHT THROUGH MONDAY...RELATIVELY LIGHT WINDS AND SEAS
EXPECTED INTO SUNDAY. A WEAK COLD FRONT MOVING SOUTH SUNDAY MORNING
MAY PRODUCE A BRIEF PERIOD OF GUSTY WINDS APPROACHING 25 KT...BUT
THIS IS NOT LIKELY. A BETTER CHANCE OF MARGINAL SMALL CRAFT ADVISORY
CONDITIONS...AT LEAST ACROSS THE OUTER COASTAL WATERS...IS EXPECTED
MONDAY.
