AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE TAUNTON MA
317 AM EDT MON MAY 25 2009

.SYNOPSIS...
HIGH PRESSURE WILL BUILD ACROSS NEW ENGLAND TODAY INTO TUESDAY. A
COMPLEX FRONTAL SYSTEM WILL LIKELY BRING A PERIOD OF UNSETTLED
WEATHER FROM TUESDAY NIGHT INTO FRIDAY. HIGH PRESSURE MAY BUILD INTO
THE REGION BY LATE IN THE WEEKEND.

&&

.NEAR TERM /UNTIL 6 PM THIS EVENING/...
COLD FRONT CONTINUES TO PROGRESS SOUTHWARD ACROSS SOUTHERNMOST NEW
ENGLAND EARLY THIS MORNING. MOST OF THE SHOWER/TSTM ACTIVITY IN
ADVANCE OF THE FRONT IS OFFSHORE...WITH A COUPLE OF STRAGGLERS ACROSS
THE LOWER HUDSON VALLEY THAT COULD CLIP A PORTION OF CT VERY EARLY
ON.

OTHERWISE...HIGH PRESSURE BUILDS INTO THE REGION TODAY BEHIND A
SECONDARY FRONT THIS AFTERNOON...BRINGING DRIER CONDITIONS ALONG
WITH NORTHERLY BREEZE GUSTING 25-30 MPH AT TIMES ACROSS THE FAR
NORTHERN TIER OF ZONES. STAYED CLOSE TO MAVMOS GUIDANCE FOR
MAXES...WHICH SHOULD YIELD HIGHS UP TO AROUND 5 DEGREES ABOVE
NORMAL.

&&

.SHORT TERM /6 PM THIS EVENING THROUGH 6 PM TUESDAY/...
HIGH PRESSURE FROM CANADA WILL CONTINUE TO BUILD SOUTHWARD
TONIGHT...USHERING IN UNSEASONABLY CHILLY AIR. IT LOOKS AS THOUGH A
GOOD PORTION OF THE FAR NORTHWEST INTERIOR WILL SEE TEMPERATURES DROP
TO BETWEEN 32 AND 36 DEGREES DUE TO RADIATION. HAVE THEREFORE ISSUED
A FROST ADVISORY FOR THOSE ZONES. OTHERWISE...CLEAR.

STRONG CANADIAN HIGH PRESSURE WILL BE CENTERED NEARBY ON TUESDAY.
THIS SHOULD RESULT IN MOSTLY SUNNY SKIES WITH MAXES A GOOD 5 TO 10
DEGREES BELOW NORMAL. WE SHOULD SEE SOME INCREASING HIGH AND MID
CLOUDS LATE IN THE DAY. HOWEVER...IT LOOKS AS THOUGH ANY SHOWER
ACTIVITY WILL HOLD OFF UNTIL AFTER 00Z.

&&

.LONG TERM /TUESDAY NIGHT THROUGH SUNDAY/...
TUESDAY NIGHT...WILL SEE AN INCREASE IN ISENTROPIC LIFT AHEAD OF A
WARM FRONT MOVING NORTH SLOWLY INTO SOUTHERN NEW ENGLAND. THIS WILL
RESULT IN SHOWERS ACROSS MUCH OF THE AREA. THIS FRONT WILL MEANDER
THROUGH NEW ENGLAND THROUGH FRIDAY MORNING RESULTING IN A CHANCE OF
SHOWERS EACH DAY THROUGH THURSDAY NIGHT. AN AREA OF ABNORMALLY HIGH
DEEP LAYER MOISTURE WILL BE OVER SOUTHERN NEW ENGLAND DURING THIS
TIME. WHERE THE FRONT AND THIS AREA OF DEEP LAYER MOISTURE
INTERSECT...THERE IS THE POTENTIAL FOR LOCALLY HEAVY RAINFALL.
TEMPERATURES WILL DEPEND ON THE LOCATION OF THE FRONT EACH DAY WITH
COOLER TEMPS NORTH OF THE FRONT AND WARMER...MORE HUMID CONDITIONS
SOUTH OF THE FRONT.

FRIDAY...DEPENDING ON THE MODEL...COULD SEE A COLD FRONT PUSH EAST
THROUGH THE CWA FRIDAY BRINGING AN END TO THE SHOWERS /GFS/ OR
SHOWERS COULD CONTINUE WITH A FRONT JUST APPROACHING THE AREA
/ECMWF/.  SATURDAY...THESE DIFFERENCES CONTINUE WITH THE GFS ALREADY
MOVING HIGH PRESSURE INTO THE AREA AND THE ECMWF BRINGING THE FRONT
THROUGH.

GIVEN THE DIFFERENCES IN COLD FRONT TIMING AND THE LOCATION AND
MOVEMENT OF THE WARM FRONT EARLIER IN THE WEEK...WILL HAVE
WIDESPREAD CHANCE POPS IN FOR MOST OF THE WEEK.

&&

.AVIATION /07Z MONDAY THROUGH FRIDAY/...
TODAY...ANY PATCHY STRATUS OR FOG WILL DISSIPATE EARLY THIS MORNING
YIELDING VFR CONDITIONS FOR THE DAY. NORTHERLY WINDS WILL GUST AROUND
25 KT THIS AFTERNOON AND KMHT AND POSSIBLY UP TO 25 KT FOR A TIME AT
KBOS AND KORH.

TONIGHT THROUGH TUESDAY...VFR WITH HIGH PRESSURE FIRMLY IN CONTROL.

OUTLOOK / TUESDAY NIGHT THROUGH FRIDAY/...

TUESDAY NIGHT AND WEDNESDAY...CONDITIONS LOWERING TO MVFR/IFR IN LOW
CLOUDS/SHOWERS AND FOG PATCHES.

THURSDAY...AREAS MVFR/IFR CONDITIONS LIKELY TO CONTINUE.

&&

.MARINE...
COLD FRONT TO MOVE OFFSHORE TO THE SOUTH OF NANTUCKET EARLY THIS
MORNING. SHOWERS AND THUNDERSTORMS TO THE SOUTH OF NANTUCKET SHOULD
PUSH OUT OF THE AREA BETWEEN 09-11Z. OTHERWISE...WINDS CONTINUE TO
SHIFT TO THE NORTH. LOOKS AS THOUGH GUSTS SHOULD REMAIN BELOW SCA
THRESHOLDS...BUT COULD APPROACH 25 KT FOR A TIME THIS AFTERNOON NEAR
THE ESSEX COUNTY COASTLINE. SEAS LOOK TO REMAIN BLO 5 FT.

MARGINAL SCA CONDS ARE POSSIBLE VERY LATE TONIGHT INTO TUESDAY AS
HIGH PRESSURE BUILDS ACROSS THE WATERS AND GRADIENT TIGHTENS. HELD
OFF ON SCA ISSUANCE FOR NOW...BUT ONE MAY HAVE TO BE ISSUED LATER
TODAY OR TONIGHT.

OUTLOOK /TUESDAY NIGHT THROUGH FRIDAY/...

INCREASING SOUTHEAST WINDS MAY BRING CONDITIONS CLOSE TO SMALL CRAFT
ADVISORY THRESHOLDS LATE TUE NIGHT. SMALL CRAFT ADVISORY CONDITIONS
MORE LIKELY TO DEVELOP ACROSS THE SOUTHERN COASTAL WATERS SOMETIME
WED INTO THU AS WINDS SHIFT SOUTH AND CONTINUE TO INCREASE. THE
TIMING IS UNCERTAIN AS IT WILL DEPEND UPON THE LOCATION OF A COLD
FRONT APPROACHING THE WATERS.

UNDERCUT WNAWAVE GUIDANCE DUE TO ITS TYPICAL HIGH BIAS WITH SOUTHERLY
FLOW...BUT MAY EVENTUALLY SEE 5+ FOOT SEAS LATE WED/THU ACROSS THE
OUTER SOUTHERN WATERS.

&&

.FIRE WEATHER...
TODAY...MINIMUM RELATIVE HUMIDITIES WILL LOWER TO 20 TO 30 PERCENT
ACROSS MUCH OF THE REGION TODAY. THIS COMBINED WITH FREQUENT
NORTHERLY WIND GUSTS AROUND 25 MPH ACROSS SOUTHERN NH HAS PROMPTED
THE ISSUANCE OF A RED FLAG WARNING FOR CHESHIRE AND HILLSBOROUGH
COUNTIES. RECENT RAINFALL FROM TSTMS AS WELL AS LIGHTER WINDS ACROSS
THE REST OF THE CWA HAS PRECLUDED THE ISSUANCE OF A RFW THERE.
