AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE TAUNTON MA
421 PM EDT SUN APR 8 2012
.SYNOPSIS...
AN UPPER DISTURBANCE COULD BRING A FEW SHOWERS TONIGHT. LOW
PRESSURE HEADING WESTWARD ACROSS THE CANADIAN MARITIMES WILL KEEP
SKIES PARTLY TO MOSTLY CLOUDY AND BRING SCATTERED SHOWERS OVER NEW
ENGLAND FROM MONDAY TO THURSDAY. A FEW SNOW SHOWERS COULD OCCUR IN
THE NORTHWEST HILLS AROUND MIDWEEK. HIGH PRESSURE WILL BRING
CLEARING SKIES FRIDAY AND A WARMING TREND INTO THE WEEKEND.
&&
.NEAR TERM /UNTIL 6 AM MONDAY MORNING/...
400 PM UPDATE...
CLOUDS CONTINUE TO ERODE FROM SOUTHWEST TO NORTHEAST LATE THIS
AFTERNOON. THIS TREND WILL CONTINUE FOR THE FIRST HALF OF
TONIGHT...WITH SKIES BECOMING PARTLY CLOUDY. THIS SHOULD ALLOW
TEMPERATURES TO DROP... A LITTLE BELOW GUIDANCE...BUT AS PER
PREVIOUS FORECAST. USED METNAM FOR DEWPOINTS FOR THE EVENING HOURS
SINCE THEY WERE DRIER AND CLOSER TO REALITY.
OVERNIGHT...A STRONG UPPER LEVEL DISTURBANCE WILL MOVE FROM ITS
CURRENT POSITION OVER THE EASTERN GREAT LAKES TO SOUTHERN NEW
ENGLAND. CLOUDS WILL INCREASE FROM WEST TO EAST. THERE IS A CHANCE
OF SHOWERS WITH THIS SYSTEM BUT AMOUNTS AT ANY LOCATION SHOULD
REMAIN BELOW 0.05 INCHES. WITH THE PASSAGE OF THIS UPPER LEVEL
DISTURBANCE...WINDS WILL BECOME GUSTY...ESPECIALLY OVER THE SOUTH
COAST AND OVER HIGHER TERRAIN TOWARD DAYBREAK. VERY COLD AIR
AT 500 MB MOVES IN...WITH TEMPERATURES THERE DROPPING FROM -20C
TODAY TO AN EVEN COLDER -30C BY 12Z. THIS WILL SET THE STAGE FOR A
QUITE UNSTABLE DAY FOR MONDAY.
&&
.SHORT TERM /6 AM MONDAY MORNING THROUGH MONDAY NIGHT/...
MONDAY...
AS THE UPPER SHORT WAVE TROUGH MOVES EAST OF THE REGION IN THE
MORNING...ANY SCATTERED SHOWERS SHOULD END. LIFTED INDICES DROP TO
ONLY +1 AND TOTAL TOTAL INDICES ARE HIGH IN THE 50S WHICH MEANS
THAT BECAUSE OF THE VERY COLD AIR ALOFT...THE ATMOSPHERE WILL
BE UNSTABLE. BUT BECAUSE IT IS STILL QUITE DRY IN THE LOW
LEVELS...THIS SHOULD MAINLY JUST RESULT IN THE DEVELOPMENT OF
CLOUDINESS AS SOON AS ANY BREAKS TRY TO FORM... QUITE SIMILAR TO
WHAT OCCURRED SUNDAY AFTERNOON. SKIES WILL ATTEMPT TO BREAK OUT
FROM SOUTHWEST TO NORTHEAST LATER IN THE DAY.
THE MAIN WEATHER STORY HOWEVER WILL BE THE WINDS. THE STEEP LAPSE
RATES SHOULD CAUSE MIXING TO OCCUR UP TO 750 TO 800 MB...WHERE THE
WINDS WILL BE 35-40 KNOTS DURING THE MORNING. LATE IN THE
AFTERNOON...THE GFS SHOWS A 50+ KNOT JET RACING INTO WESTERN MA
FROM EASTERN NY STATE. BUFKIT SOUNDING SHOW A SUDDEN SURGE IN WIND
GUSTS OVER WESTERN SITES BETWEEN 4 PM AND 6 PM. IN GENERAL...AM
EXPECTING SUSTAINED WINDS OF 20 TO 25 MPH AND GUSTS TO 30 TO 40
MPH BUT WOULD NOT BE SURPRISED TO SEE GUSTS TO 45 MPH AT TIMES
ESPECIALLY IN ANY PARTLY SUNNY AREAS LATE IN THE DAY. THESE VALUES
ARE JUST BELOW THE THRESHOLDS FOR A WIND ADVISORY...WHICH REQUIRES
SUSTAINED WINDS OF 31 MPH OR GUSTS TO 46 MPH.
PER COORDINATION WITH STATE FIRE OFFICIALS...WE HAVE ISSUED A RED
FLAG WARNING FOR OUR ENTIRE FORECAST AREA FROM LATE MONDAY MORNING
THROUGH EARLY MONDAY EVENING. MEAN RELATIVE HUMIDITIES WILL REACH
A MINIMUM OF 25-30 PERCENT IN CONNECTICUT AND WESTERN MA...BELOW
THE 30 PERCENT THRESHOLD. THEY WILL RANGE FROM 30 TO 35 PERCENT
ELSEWHERE EXCEPT 40 TO 45 PERCENT ON CAPE COD AND THE ISLANDS.
HOWEVER OFFICIALS FELT THAT DESPITE THESE HIGHER VALUES...THE
WINDS AND THE DRY CONDITIONS WOULD OUTWEIGH THE SLIGHTLY HIGHER
HUMIDITY FACTOR. SOME MODELS SHOW SHOWERS...WITH UP TO 0.05 INCHES
OF RAINFALL...OCCURRING THROUGH MIDDAY IN SOUTHERN NH. THAT WOULD
MAKE SOMEWHAT LESS OF A RISK THERE BUT IT IS NOT EXPECTED TO BE
ENOUGH RAINFALL TO REDUCE THE RISK ENTIRELY.
HAVE REDUCED MAX TEMPS A FEW DEGREES FROM PREVIOUS FORECAST DUE TO
MORE CLOUD COVER EXPECTED. MAVMOSGUID USED... STILL SHOULD REACH
MID TO UPPER 50S MOST AREAS.
MONDAY NIGHT...
THE REGION IS BETWEEN UPPER LEVEL SHORT WAVES AND THUS CONDITIONS
SHOULD BE RELATIVELY QUIET. WINDS WILL DIMINISH CONSIDERABLY AFTER
SUNSET AND SKIES WILL BE PARTLY CLOUDY. CLOUDS INCREASE LATE FROM
THE WEST AND THERE IS A SLIGHT CHANCE OF A RAIN OR SNOW SHOWER IN
THE SLOPES OF THE BERKSHIRES TOWARD DAYBREAK. MAVMOSGUID BIAS
CORRECTED GRIDS USED.
&&
.LONG TERM /TUESDAY THROUGH SUNDAY/...
BIG PICTURE...
CLOSED LOW PRESSURE HANGS OVER QUEBEC EARLY WEEK...THEN SWINGS
ACROSS THE NORTHEAST USA MIDWEEK AND OFF TO THE EAST FRIDAY. UPPER
RIDGE THEN BUILDS OVER THE REGION FRIDAY AND SATURDAY. ALL MODELS
SEEM IN AGREEMENT ON LARGE SCALE FLOW...SO NO ONE MODEL FAVORED AT
THIS TIME.
TUESDAY...A SHORTWAVE MOVES AROUND THE UPPER LOW AND CROSSES
SOUTHERN NEW ENGLAND TUESDAY AFTERNOON.
THE AIRMASS IS SUFFICIENTLY DRY MONDAY NIGHT TO LIMIT THE EXTENT OF
SHOWERS...BUT CYCLONIC FLOW AND COLD POOL DRIVEN INSTABILITY ALOFT
ARGUE FOR AT LEAST A MINIMUM CHANCE. WILL HAVE SLIGHT CHANCE POPS
MONDAY NIGHT. TEMPS ARE A BLEND OF MOS.
WITH THE SHORTWAVE MOVING THROUGH ON TUESDAY AND WITH CONTINUED
INSTABILITY FROM THE COLD POOL...TOTALS AROUND 50 WHILE MID LEVEL
LAPSE RATES ARE 6.5C AND OCCASIONALLY 7C/KM...WE WILL CONTINUE TO
RUN WITH CHANCE POPS. THE INSTABILITY ALSO CARRIES A CONCERN FOR
THUNDER...BUT NOT ENOUGH COMING TOGETHER TO MENTION AT THIS TIME.
TEMPS ARE A BLEND OF MOS.
WEDNESDAY-THURSDAY...
CLOSED UPPER LOW OPENS INTO A TROUGH AND SWEEPS ACROSS NEW ENGLAND.
THE AIRMASS TAKES ON A DEEP MOISTURE FIELD WITH THE COLD POOL
INSTABILITY AND SHARP CYCLONIC FLOW ALOFT. EXPECT MAINLY CLOUDY
SKIES AND SUPPORT FOR SCATTERED SHOWERS. TEMPERATURES WILL BE COOL
ENOUGH SO THAT NIGHTTIME COOLING COULD TRIGGER A PHASE CHANGE TO
SNOW IN WESTERN MASS AND SOUTHWEST NH...ALTHOUGH DAYTIME TEMPS
SHOULD BE WARM ENOUGH FOR ALL RAIN.
FRIDAY-SATURDAY...
HIGH PRESSURE BUILDS IN WITH DRIER AIR. STILL SOME QUESTION AS TO
TIMING OF THE CLEARING. A SLOWER MOVING TROUGH WOULD MEAN MORE
CLOUDS FRIDAY...THE 00Z ECMWF POINTS IN THIS DIRECTION WHILE THE 00Z
GFS SHOWS RESIDUAL MOISTURE ONLY AROUND 800-850 MB. WE WILL CARRY
LINGERING MORNING CLOUDS ESPECIALLY IN EASTERN MASS...BUT WITH A
CLEARING TREND THROUGH THE DAY. MOSTLY SUNNY SATURDAY BUT WITH
INCREASING SKY COVER LATE. OBVIOUSLY ROOM FOR THIS TIMING TO CHANGE
OVER THE NEXT SEVERAL FORECASTS.
&&
.AVIATION /20Z SUNDAY THROUGH FRIDAY/...
FORECASTER CONFIDENCE LEVELS...
LOW...LESS THAN 30 PERCENT
MODERATE...30 PERCENT TO 60 PERCENT
HIGH...GREATER THAN 60 PERCENT
THROUGH TONIGHT...HIGH CONFIDENCE IN VFR CONDITIONS. CANNOT RULE
OUT A FEW MVFR CIGS WITHIN LIGHT SHOWERS...MAINLY IN WESTERN AREAS
LATE. LOW CONFIDENCE ON EXACT TIMING AND LOCATION.
KBOS TERMINAL...HIGH CONFIDENCE IN TAF. VFR CONDITIONS.
MONDAY...MODERATE CONFIDENCE. EXPECT MAINLY VFR CONDITIONS WITH
SOME MVFR CIGS WITHIN ANY SHOWERS...MAINLY IN THE MORNING.
WESTERLY WINDS WILL BE QUITE STRONG WITH GUSTS UP TO 30-35 KTS
WITH AN ISOLATED GUSTS AS HIGH AS 40 KTS POSSIBLE LATE IN THE
AFTERNOON.
MONDAY NIGHT...HIGH CONFIDENCE...VFR CONDITIONS. WINDS DIMINISHING
AFTER SUNSET. A FEW SHOWERS OF RAIN OR SNOW IN SLOPES OF THE
BERKSHIRES MAY CAUSE ISOLATED MVFR CONDITIONS TOWARD DAYBREAK.
OUTLOOK...TUESDAY THROUGH THURSDAY...
UPPER LOW PRESSURE AND ASSOCIATED CLOUDS/INSTABILITY WILL AFFECT
SOUTHERN NEW ENGLAND THROUGH THE PERIOD. CEILINGS ARE EXPECTED TO
REMAIN VFR...BUT WITH SCATTERED SHOWERS THAT COULD BRING
CEILINGS/VSBYS DOWN TO MVFR AT ALMOST ANY TIME. TEMPERATURES IN
WESTERN MASS AND SOUTHWEST NH MAY BE COLD ENOUGH EACH NIGHT TO
CONVERT THE RAIN SHOWERS TO SNOW SHOWERS.
&&
.MARINE...
THIS AFTERNOON-TONIGHT... GALE WARNING HAS BEEN ISSUED FOR
SOUTHERN WATERS FOR MONDAY. WINDS AND SEAS TONIGHT WILL BE BELOW
SCA THRESHOLDS AS NORTHWEST WINDS GUSTING UP TO 20 KTS DIMINISH AFTER
SUNSET. WINDS INCREASE TO SMALL CRAFT ADVISORY LEVELS ON THE
SOUTH COAST LATE.
MONDAY...
GALE WARNING FOR SOUTHERN WATERS...BAYS...AND SOUNDS EXCEPT SMALL
CRAFT ADVISORY FOR NARRAGANSETT BAY AND FOR CAPE COD BAY AND THE
WATERS NORTH OF PROVINCETOWN INCLUDING BOSTON HARBOR. WESTERLY
WINDS WILL GUST TO 30 TO 40 KTS IN THE GALE WARNING AREA AND TO
25-33 KTS IN THE SMALL CRAFT ADVISORY AREA. WILL NEED TO MONITOR
IN CASE THOSE AREAS NEED UPGRADING TO GALES. SEAS BUILD TO 8 TO 10
FEET OVER THE SOUTHERN WATERS.
MONDAY NIGHT...
DIMINISHING WINDS AND SLOWLY SUBSIDING SEAS. WINDS SHOULD DIMINISH
TO BELOW 20 KTS BY DAYBREAK AND SEAS WILL SUBSIDE A LITTLE...TO 6 TO 8
FEET SOUTH OF NANTUCKET.
OUTLOOK...TUESDAY THROUGH THURSDAY...
TUESDAY THROUGH THURSDAY...
LINGERING 5 FOOT SEAS ON THE SOUTHERN OUTER WATERS TUESDAY AND
WEDNESDAY. OTHERWISE WINDS AND SEAS WILL REMAIN BELOW SMALL CRAFT

.FIRE WEATHER...

THE 30 PERCENT THRESHOLD. THEY WILL RANGE FROM 30 TO 35 PERCENT
ELSEWHERE EXCEPT 40 TO 45 PERCENT ON CAPE COD AND THE ISLANDS.
HOWEVER OFFICIALS FELT THAT DESPITE THESE HIGHER VALUES...THE
WINDS AND THE DRY CONDITIONS WOULD OUTWEIGH THE SLIGHTLY HIGHER
HUMIDITY FACTOR. SOME MODELS SHOW SHOWERS...WITH UP TO 0.05 INCHES
