AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE TAUNTON MA
200 PM EDT MON MAR 11 2013
.SYNOPSIS...
MILD AND DRY CONDITIONS WILL CONTINUE TODAY. WET WEATHER WILL
IMPACT THE REGION...POSSIBLY HEAVY AT TIMES...TUESDAY INTO TUESDAY
NIGHT ALONG AND AHEAD OF A COLD FRONT SWEEPING ACROSS NEW ENGLAND.
A SECONDARY COLD FRONT/TROUGH MAY TRIGGER A FEW RAIN AND OR SNOW
SHOWERS LATE WED/WED EVENING. BEHIND THIS FRONT...A MUCH COOLER
AIRMASS OVERSPREADS THE REGION LATE THIS WEEK AND INTO NEXT
WEEKEND. MAINLY DRY WEATHER WILL BE FEATURED DURING THIS TIME.
&&
.NEAR TERM /UNTIL 6 PM THIS EVENING/...
145 PM UPDATE...
STILL NOTING LOW CLOUDS HUGGING ALONG THE S COAST WITH S-SW WINDS
IN PLACE...OTHERWISE CLOUDS ARE TENDING TO THIN. VISIBLE SATELLITE
AND OBS SHOWING MAINLY MID AND HIGH CLOUDS ACROSS NEW ENGLAND INTO
NY STATE. NE 88D REGIONAL RADAR SHOWING PRECIP MOVING IN THE SW
FLOW ACROSS INTERIOR AREAS...BUT NO GROUND TRUTH WITH TEMP/DEWPT
SPREADS 10-15 DEGS SO DISSIPATING BEFORE REACHING THE GROUND. ALSO
SEE PATCHY PRECIP AHEAD OF COLD FRONT MOVING ACROSS NY STATE AND
CENTRAL PA. COLD FRONT STILL ACROSS OHIO VALLEY AND SLOWLY MOVING
E.
WILL CONTINUE TO SEE CLOUDS LOWER AND THICKEN MAINLY ACROSS
WESTERN AREAS THROUGH THE REMAINDER OF THE DAY. EXPECT TEMPS TO
TOP OFF IN THE MID 40S TO LOWER 50S...MILDEST ACROSS THE LOWER CT
VALLEY...AND COOLER FOR SHORELINE LOCALES AND AREAS WITH A DEEP
SNOW PACK.
&&
.SHORT TERM /6 PM THIS EVENING THROUGH TUESDAY NIGHT/...
TONIGHT...
MOSTLY CLOUDY CONDITIONS. SHOWERS WILL BE ON THE INCREASE TOWARDS
MORNING LIKELY ACROSS THE CT VALLEY REGION. CONTINUED ONSHORE
SOUTHERLY FLOW...INCREASING SURFACE DEWPOINTS COUPLED WITH CLOUDS
WILL KEEP MINIMUM TEMPERATURES MILD IN THE LOW-MID 40S DOWN TO AS
LOW AS THE UPPER 30S. WITH INCREASING MOISTURE ACROSS EITHER A DEEP
SNOW PACK AND/OR COLD GROUND...THERE EXISTS A GOOD LIKELIHOOD FOR
PATCHY FOG AND/OR LOW CLOUDS.
TUESDAY INTO TUESDAY NIGHT...
FIRST...EVALUATING A PROMINENT BLOCKING PATTERN ACROSS THE DAVIS
STRAIGHT...LIKED HOW BOTH THE 11.0Z CANADIAN AND ECMWF WERE HANDLING
THE H5 LOW WITH THE STRONGER POLAR VORTEX OVER THE HIGH LATITUDES.
DISCOUNTED THE NAM...BUT LIKENED THE 11.0Z WRF-ARW TO INCLUDE IN
POTENTIAL FORECAST OUTCOMES.
SECOND...BEFORE GOING INTO DETAIL...WILL SAY IN BREVITY THAT THE
FORECAST HINGES UPON A CONSERVATIVE AMOUNT OF STORM TOTAL RAINFALL
RANGING AROUND AN INCH. STRONG MOIST ADVECTION THROUGH THE PERIOD
WITH DEWPOINTS GETTING INTO THE LOW 50S WILL MELT AWAY ANY REMNANT
SNOW PACK. COUPLED WITH ANTICIPATED RAINFALL...AND WE COULD BE
CONTENDING WITH FLOOD HEADLINES. HAVE MODIFIED DETAILS WITHIN THE
HYDROLOGY DISCUSSION BELOW.
THIRD...THE DETAILS...BASED ON THE CANADIAN/ECMWF...A COLD FRONT
WILL SWEEP ACROSS NEW ENGLAND AROUND MIDNIGHT WEDNESDAY. THERE IS
THE POTENTIAL FOR A WEAK WAVE LOW /AS HINTED BY A MAJORITY OF THE
MODEL GUIDANCE/ TO DEVELOP ALONG THE FRONT RESULTING IN A LOCAL
ENHANCEMENT OF THE RAINFALL OUTCOMES /EMBEDDED HEAVIER RAINS/.
ANTICIPATING A DISTINCT LINE OF WET WEATHER ALONG AND AHEAD OF THE
COLD FRONT SO WENT WITH HIGH CATEGORICAL POPS /NO BRAINER AT THIS
POINT...ITS GOING TO RAIN/.
AS MENTIONED EARLIER...CONTINUED WARM AND MOIST SOUTHERLY ADVECTION
WILL RESULT IN INCREASING DEWPOINTS ACROSS THE REGION. COULD TURN
INTO A SOUPY MESS AS SUCH AIR INTERACTS WITH THE COLDER GROUND
SURFACE OF SOUTHERN NEW ENGLAND. THERE IS A DISTINCT POSSIBILITY FOR
PATCHY TO AREAS OF DENSE FOG.
EVALUATING THE CONVECTIVE POTENTIAL...THERE COULD BE IN FACT SOME
ISOLATED THUNDER OUT E/SE OF CAPE COD OVER THE OCEAN...BUT A
MAJORITY OF THE CONVECTIVE INDICES ACROSS THE INTERIOR DO NOT
SIGNIFY MUCH WEIGHT TOWARDS THUNDER POTENTIAL. STILL...THE FRONTO-
GENETICAL LIFT OF THE SYSTEM AND THE POSSIBILITY OF A AFOREMENTIONED
WEAK WAVE LOW...EMBEDDED HEAVIER RAINS ARE NOT OUT OF THE QUESTION.
COULD SEE LOCALIZED HEAVIER RAINFALL AMOUNTS FOR SOME AREAS.
IN CLOSING...WILL ALLOW LATER SHIFTS TO EVALUATE RAINFALL OUTCOMES
ACCORDINGLY TOWARDS THE ISSUANCE OF FLOOD HEADLINES. AGAIN...PLEASE

HIGHLIGHTS...
* MUCH COOLER TEMPERATURES ARRIVING WED NGT/THU
* MAINLY DRY WEATHER PREVAILS
SYNOPTIC OVERVIEW AND MODEL PREFERENCES...
00Z GFS IN FAIRLY GOOD AGREEMENT ON THE LARGE SCALE FLOW WITH THE
12Z ECMWF AND ECENS THIS PERIOD. THUS THIS FORECAST BASED ON A
GFS/ECMWF BLEND. THE UPPER AIR PATTERN FEATURES A HIGH AMPLITUDE
TROUGH MOVING ACROSS THE EASTERN STATES WED THEN TAKING ON A
NEGATIVE TILT AS IT TRAVERSES NORTHEAST INTO THE MARITIMES THU. THIS
INDUCES A DOWNSTREAM RIDGE OVER SOUTHERN GREENLAND AND THE DAVIS
STRAIT. THIS WILL SUPPORT BELOW NORMAL HEIGHTS AND COOLER THAN
NORMAL TEMPS ACROSS NEW ENGLAND BEGINNING WED NGT/THU AND CONTINUING
INTO NEXT WEEKEND.
DAILY SENSIBLE WEATHER DETAILS...
WEDNESDAY...
DESPITE DEEP MOISTURE PLUME AND SURFACE COLD FRONT OFFSHORE...
NEGATIVE TILT MID/UPR TROUGH SWINGING ACROSS THE REGION SHOULD BE
SUFFICIENT TO TRIGGER SCATTERED RAIN/SNOW SHOWERS ACROSS THE AREA.
COLUMN STRUGGLES TO SATURATE AND THIS WILL LIKELY LIMIT AREA
COVERAGE OF SHOWERS. BLYR STILL WARM ENOUGH TO SUPPORT RAIN
SHOWERS ALONG THE COAST...BUT COULD BE SNOW SHOWERS FARTHER
INLAND. OTHERWISE WED IS A DECENT DAY BEFORE THE TROUGH PASSAGE
WITH DRY WEATHER AND MILD TEMPS LINGERING WITH HIGHS IN THE U40S-
L50S... WARMEST ACROSS RI AND EASTERN MA.
THURSDAY...
UPPER TROUGH OVER THE REGION AND WILL PROVIDE MOIST CYCLONIC FLOW
ACROSS THE AREA. COLD TEMPS ALOFT WILL ALSO PROVIDE STEEP LAPSE
RATES. ALL OF THIS WILL SUPPORT A RISK FOR ISOLATED OR WIDELY
SCATTERED DIURNAL SNOW SHOWERS. CHILLY WITH HIGHS ONLY IN THE
U30S- L40S COMBINED WITH A BRISK NW WIND.
FRIDAY/SATURDAY...
MEAN MID LEVEL TROUGH AXIS IS NORTHEAST OF THE REGION ACROSS
QUEBEC INTO THE MARITIMES. THIS WILL SUPPORT DRY BUT COOLER THAN
NORMAL WEATHER. NEW 00Z ECMWF DIFFERING FROM PREVIOUS RUN IN
BRINGING A LOW AMPLITUDE PACIFIC SYSTEM IN NEW ENGLAND SAT. WILL
DISCOUNT FOR NOW GIVEN THIS IS DIFFERENT THAN ITS ENSEMBLE ECENS
AND MUCH OF THE REMAINING GUID. ECENS 850 MEAN TEMP OVER SNE IS
ABOUT -8C TO -10C. THUS MOS HIGHS IN THE U30S AND L40S SEEMS
REASONABLE...CHILLY AND BELOW NORMAL.
SUNDAY AND BEYOND...
LOTS OF SPREAD HERE REGARDING SHORT WAVE TIMING...AMPLITUDE AND
PHASING...WHICH IS EXPECTED AT THIS TIME RANGE. THE GFS HAS A WEAK
WAVE PASSING SOUTH OF NEW ENGLAND SUN. MEANWHILE THE NEW 00Z EC
AND ITS 51 MEMBER ENSEMBLE MEAN ARE SLOWER AND MUCH STRONGER WITH
A COASTAL/WINTER STORM IMPACTING NEW ENGLAND EARLY NEXT WEEK. ITS
7 DAYS AWAY BUT NEEDS TO BE WATCHED GIVEN THE RETURNING BLOCK
PATTERN AND THE CLUSTERING OF A HIGH NUMBER OF ECENS MEMBERS.

FORECASTER CONFIDENCE LEVELS...
LOW...LESS THAN 30 PERCENT.
MODERATE...30 TO 60 PERCENT.
HIGH...GREATER THAN 60 PERCENT.
THROUGH 00Z...HIGH CONFIDENCE.
EXPECT MAINLY VFR CONDITIONS EXCEPT MVFR CIGS ALONG S COASTAL
AREAS.
TONIGHT THROUGH TUESDAY NIGHT...MODERATE CONFIDENCE.
TONIGHT...EXPECT VFR TO CONTINUE THROUGH MIDNIGHT AWAY FROM THE S
COAST...WHERE MVFR CIGS WILL LINGER. CIGS LOWERING TO MVFR AFTER
MIDNIGHT FOR MOST AREAS. VFR VSBYS WILL LOWER TO MVFR-IFR ACROSS
CENTRAL AND WESTERN AREAS IN PATCHY FOG AFTER MIDNIGHT. LLWS
POSSIBLE ACROSS CT VALLEY AFTER 06Z.
TUESDAY-TUESDAY NIGHT...EXPECT CONDITIONS TO LOWER TO IFR-LIFR
FROM W-E AS RAIN MOVES IN WITH DEEP LOW AND MID LEVEL MOIST FLOW
ON S-SW WINDS. MAY SEE LOCALLY HEAVY RAINFALL NEAR AND AHEAD OF
APPROACHING FRONT. LLWS ON 40-50 KT S-SW LOW LEVEL JET...WHICH
SHOULD SHIFT OFFSHORE AS THE FRONT PASSES TUE AFTERNOON/NIGHT.
CONDITIONS IMPROVE TO VFR SHORTLY AFTER FRONTAL PASSAGE TUE NIGHT
ACROSS CENTRAL AND WESTERN AREAS...BUT MAY LINGER TO AROUND 12Z

.MARINE...
1020 AM UPDATE...
SWELLS CONTINUE TO ROLL INTO THE COASTAL WATERS...THOUGH THEY ARE
SLOWLY SUBSIDING. NOTED 7 FT AT BUOY 44013 AT 12Z...AND STILL UP
TO 8 FT AT BUOY 44098. WILL CONTINUE SMALL CRAFT FOR HAZ SEAS
THROUGH CURRENT EXPIRE TIME THEN EVALUATE IF IT NEEDS TO BE
EXTENDED LATER TONIGHT.
PREVIOUS DISCUSSION...
HIGH CONFIDENCE.
SMALL CRAFT ADVISORIES FOR HAZARDOUS SEAS CONTINUE INTO TUESDAY
MORNING. SEAS OF 10 TO 15 FEET INITIALLY OVER THE OUTER WATERS
GRADUALLY DIMINISHING TO 5 TO 8 FEET INTO TONIGHT.
WINDS WILL INCREASE OUT OF THE S-SE AHEAD OF A COLD FRONT WHICH
WILL SWEEP ACROSS THE WATERS AROUND MIDNIGHT WEDNESDAY. ANTICIPATE
RAINS RESULTING IN REDUCED VISIBILITIES. WINDS WILL GUSTS OUT OF
THE SOUTH LATE TUESDAY INTO WEDNESDAY MORNING IN EXCESS OF 25 KTS.
SMALL CRAFT ADVISORIES WILL LIKELY NEED TO BE AMENDED FOR BOTH
HAZARDOUS SEAS AND GUSTY WINDS.
OUTLOOK...WEDNESDAY THROUGH FRIDAY...
IMPROVING WEATHER WED WITH COLD FRONT OFFSHORE. NW WINDS INCREASE
THU AND FRI WITH GUSTS OF 20-30 KT. VSBY GOOD MUCH OF THIS PERIOD
WITH THE EXCEPTION OF SCATTERED RAIN SHOWERS LATE WED/WED EVE AND
THEN AGAIN IN SCATTERED SNOW SHOWERS LATER THU.
&&
.HYDROLOGY...
A STRONG COLD FRONT WILL IMPACT THE AREA ON TUESDAY INTO TUESDAY
NIGHT BRINGING WIDESPREAD RAINFALL WITH THE POSSIBILITY OF EMBEDDED
HEAVIER SHOWERS. WHILE SOME FORECAST GUIDANCE IS FORECASTING 2 TO
2.5 INCHES OF RAINFALL...HAVE GONE A MORE CONSERVATIVE APPROACH WITH
A BLEND OF THE ECMWF/CANADIAN/WRF-ARW PRODUCING AMOUNTS AROUND 1
INCH.
THE PRESENT FORECAST HAS THE HEAVIEST AXIS OF RAINFALL THROUGHOUT
THE CONNECTICUT VALLEY REGION...BUT THIS IS NOT CERTAIN. THE AXIS
CAN EASILY SHIFT EAST OR WEST. THE BIGGEST CONCERN IS THE PROXIMITY
OF THE HEAVIEST AXIS COLLOCATED WITH THE DEEPER SNOW PACK.
ANTICIPATING GRADUAL SNOW MELT OVER THE NEXT 24 HOURS...EXPEDITED
MORE SO WITH INCREASING DEWPOINTS INTO TUESDAY. THE COMBINATION OF
SNOW MELT AND ANTECEDENT RAINS CAN RESULT IN SMALL RIVERS AND
STREAMS TO SWELL OUT OF THEIR BANKS...ALONG WITH SOME URBAN AND POOR
DRAINAGE FLOODING ACROSS THE MORE VULNERABLE AREAS.
PER COLLABORATION WITH THE NERFC...IF 1.5 INCHES OF PRECIP FALLS
OVER THE EASTERN HALF OF THE FORECAST AREA...AT MINIMUM WE WOULD SEE
SEVERAL MAIN-STEM RIVER POINTS REACHING ACTION STAGE...WITH THE
POSSIBILITY OF A COUPLE REACHING FLOOD STAGE. THE MORE SUSCEPTIBLE
RIVERS INCLUDE THE CHARLES RIVER AT DOVER...THE PAWTUXET AT
CRANSTON...AND THE ASSABET RIVER AT MAYNARD. RIGHT NOW THE FEELING
IS THAT SOME OF THESE RIVER MAY JUST HIT ACTION STAGE...BUT WE
WILL HAVE TO WATCH CLOSELY AND SEE HOW MUCH RAINFALL FALLS WITHIN
THEIR BASINS.
