AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE TAUNTON MA
1016 AM EST WED FEB 29 2012
.SYNOPSIS...
A SERIES OF LOW PRESSURE SYSTEMS PASSING NEAR AND SOUTH OF THE
REGION WILL BRING PERIODS OF ACCUMULATING SNOW AND MIXED
PRECIPITATION WEDNESDAY AFTERNOON INTO THURSDAY. FAST MOVING HIGH
PRESSURE WILL BRING DRY WEATHER ON FRIDAY. LOW PRESSURE PASSING
WELL WEST OF THE REGION WILL RESULT IN RAINY AND MILD WEATHER WITH
BLUSTERY WINDS SATURDAY...FOLLOWED BY DRY CONDITIONS INTO EARLY
NEXT WEEK.
&&
.NEAR TERM /UNTIL 6 PM THIS EVENING/...
1015 AM UPDATE...
12Z NAM MOVED BACK TO A COLDER SOLUTION FROM WHAT WAS OBSERVED FOR
THE 06Z RUN SO WE HAVE NOT MADE ANY NOTABLE CHANGES TO THE
EXISTING FORECAST. PRECIP MAY BEGIN AS SOME RAIN IN THE COASTAL
PLAIN GIVEN MILD TEMPS...BUT SHOULD QUICKLY CHANGE TO SNOW AS
TEMPS WET BULB TO 32-34 DEGREES. SNOW MAY HAVE A DIFFCULT TIME
ACCUMULATING ON THE ROADS NEAR THE COAST DUE TO SLIGHTLY ABOVE
FREEZING TEMPS SO MUCH OF THE ACCUM HERE MAY BE CONFINED TO COLDER
SURFACES AND GRASSY AREAS.
PRECIP MOVING IN A BIT QUICKER AND SHOULD OVERSPREAD THE REGION
FROM NOON TO 3 PM FROM WEST TO EAST.
PREV FORECAST DISCUSSION...
MADE SOME CHANGES TO THE WINTER WEATHER HEADLINES. THIS CONTINUES
TO BE A VERY DIFFICULT TO FORECAST...AND EVEN NOW SOME OF THE
DETAILS HAVE YET TO BE RESOLVED COMPLETELY. THIS IS THE BEST
FORECAST WE HAVE AT THIS POINT IN TIME...AND FURTHER ADJUSTMENTS
WILL BE POSSIBLE.
THE MAIN PROBLEM WILL BE THE THERMAL PROFILES AS THE PRECIPITATION
MOVES IN THIS EVENING...AND THE AMOUNT OF DYNAMIC COOLING THAT CAN
BE GENERATED. 29/00Z GFS CONTINUES TO BE THE WARMEST MODEL WITHIN
THE BOUNDARY LAYER. THIS DOES NOT LOOK REASONABLE WITH THE CURRENT
SYNOPTIC SETUP OF A LOW PRESSURE PASSING SOUTH OF NEW ENGLAND AND
A HIGH PRESSURE OVER EASTERN CANADA...A CLASSIC COLD-AIR DAMMING
SIGNATURE. BOTH THE 29/00Z ECMWF AND NAM LOOK MUCH MORE REASONABLE
WITHIN THE BOUNDARY LAYER...WITH THE ECMWF 850 MB TEMPERATURES
NEARLY 3C LOWER THAN THE NAM. THE 29/00Z UKMET WAS ALSO COLDER
THAN THE NAM AT THIS LEVEL.
THE PRIMARY FACTOR FOR DETERMINING PRECIPITATION TYPE WILL OCCUR
WITHIN THE 4500-9500 FT LAYER. THE ECMWF IS AGAIN SLOWER TO BRING
IN WARMER AIR WITHIN THIS LAYER. SHOULD THIS SOLUTION VERIFY...
SNOW COULD LINGER LONGER THAN CURRENTLY FORECAST. DESPITE THE POOR
HANDLING OF THE BOUNDARY LAYER AIRMASS...THE GFS AGREES WITH THE
NAM IN BRINGING JUST ENOUGH WARM AIR NORTH TO KEEP MIXED
PRECIPITATION IN THE FORECAST.
WINTER STORM WARNINGS ARE NOW POSTED FOR AREAS WHERE CONFIDENCE IS
GREATEST FOR SIGNIFICANT ACCUMULATING SNOW. WINTER WEATHER
ADVISORIES POSTED ELSEWHERE. SOME OF THESE ADVISORIES...MAINLY
ACROSS SOUTHWEST AND SOUTH CENTRAL MASSACHUSETTS MAY NEED TO BE
UPGRADED TO WARNINGS IF THE COLDER SOLUTION VERIFIES. CURRENT
THINKING IS THERE WILL BE A SLIGHT PRECIPITATION SHADOW WITHIN
PORTIONS OF THE LOWER CT RIVER VALLEY IN MASSACHUSETTS DUE TO
STRONG EASTERLY FLOW. THIS EASTERLY FLOW WILL ALSO BRING
SUFFICIENTLY WARM AIR OFF THE OCEAN TO REDUCE SNOW ACCUMULATIONS.
PREVIOUS TIMING ON ONSET...EARLY THIS AFTERNOON...STILL LOOKS
REASONABLE.
&&
.SHORT TERM /6 PM THIS EVENING THROUGH 6 AM THURSDAY/...
WARMER AIR STARTS TO MOVE OVER SOUTHERN NEW ENGLAND CHANGING THE
SNOW TO MORE OF A WINTRY MIX...MAINLY SOUTH OF I-90 IN MA...CT AND
RI. RAIN SHOULD BE THE DOMINANT TYPE ACROSS CAPE COD AND THE
ISLANDS. WHILE LIGHTER IN INTENSITY...STILL EXPECTING ACCUMULATING
SNOW AND SLEET FOR MOST OF THE REGION.
&&
.LONG TERM /THURSDAY THROUGH TUESDAY/...
HIGHLIGHTS...
* ACCUMULATING SNOW AND MIXED PRECIP WILL LAST INTO INTO THU NIGHT
* ANOTHER SYSTEM WILL BRING A GOOD SOAKING ACROSS SNE ON SATURDAY
WHILE SOUTHERN NH MAY SEE SOME MIXED PRECIP EARLY SAT MORNING.
CONFIDENCE...
INCREASING CONFIDENCE ON THE SYSTEM MOVING THROUGH ON THURSDAY.
HIGH CONFIDENCE THAT ACCUMULATING SNOW...INCLUDING WARNING
CRITERIA WILL OCCUR ESP ACROSS NORTHERN MASS AND SOUTHERN NEW
HAMPSHIRE. FOR THE SATURDAY SYSTEM...HIGH CONFIDENCE THAT PRECIP
WILL OCCUR...MODERATE CONFIDENCE ON TIMING AND PRECIP TYPE.
THURSDAY...MODERATE CONFIDENCE.
THIS WAS THE MAIN FOCUS FOR THIS FORECAST PACKAGE AS THERE ARE STILL
SOME DETAILS THAT NEED TO BE IRONED OUT FOR THIS UPCOMING SYSTEM.
GENERALLY...A THIRD AREA OF PRECIP WILL MOVE ACROSS THE FORECAST
AREA THURSDAY MORNING AS THE SECONDARY LOW DEVELOPS SOUTH OF
NANTUCKET. THIS LOW WILL SLOWLY MOVE EASTWARD THROUGH THE DAY
THURSDAY AND FINALLY EJECT OVER THE ATLANTIC WATERS BY LATE THURSDAY
AS UPPER LEVEL DISTURBANCE PUSHES IT OUT. THIS SYSTEM WILL BRING A
MIX BAG OF PRECIP ACROSS THE AREA CAUSING FOR A MESSY MORNING
COMMUTE ON THURSDAY.
MODELS...
OVERALL MODEL TRENDS LINE UP WITH THIS SYSTEM WHICH HELPS INCREASE
FORECASTERS CONFIDENCE. DECIDED TO LEAN TOWARDS THE NAM/ECMWF RATHER
THAN THE GFS AS IT DOES NOT HANDLE COLD AIR DAMMING ALL TO WELL.
ALSO THE NAM/ECMWF HAVE BEEN HANDING THIS SYSTEM THE PAST FEW RUNS
WELL AND HAS A GOOD TRACK RECORD FOR SYSTEM THIS MONTH. WHILE THE
NAM IS STILL COLDER IN THE VERTICAL PROFILE BLENDING THE ECMWF AND
CANADIAN WILL HELP CORRECT ANY BIAS THAT THE NAM HAS. FOR QPF DID A
BLEND WITH THE SREF/NAM/ECMWF/GFS. ALL MODELS HAVE SIMILAR OUTPUTS
WITH A FEW BEING MORE THAN OTHERS...SO TRENDED TOWARDS AN AVERAGE.
ONE CONCERN IS THE POTENTIAL FOR MESOSCALE BANDING...HAVE TRIED TO
INCORPORATE THAT INTO THE GRIDS. SURFACE TEMPS WHERE TRENDED TO THE
NAM/PREV FORECAST AS MODELS HAVE BEEN COMING IN COOLER THAN THERE
12Z RUNS. OVERALL GENERAL MODEL AGREEMENT WITH THIS SYSTEM.
DETAILS...
COASTAL LOW WILL DEVELOP ACROSS LONG ISLAND MOVE SOUTH OF ACK DURING
THIS TIME FRAME. THIS LOW WILL KEEP PRECIP GOING ACROSS THE AREA
THROUGH THE DAY AND INTO THE OVERNIGHT HOURS. THIS LOW WILL DEEPEN
AS IT MOVES THROUGH AND CAUSE ENHANCEMENT OVER THE REGION...ALONG
AND NORTH OF THE TURNPIKE. RAIN/SNOW LINE WILL CONTINUE TO MOVE
NORTHWARD AS TEMPS INCREASE ACROSS RI/NORTHERN CT AND THE CAPE AS
THICKNESSES MOVES NORTHWARD. ONCE THING TO NOTE IS THE SURFACE
TROUGHING ACROSS THE 95-CORRIDOR. BELIEVE THIS IS WHERE THE COASTAL
FRONT WILL SET UP AS WARM AIR ACROSS THE WATERS WILL MEET THE COLD
AIR OVER THE LAND...WHICH WILL LEAD TO SOME TRICKY AMOUNTS ACROSS
THE COASTAL REGIONS. WHERE THE COASTAL FRONT SETS UP...AND AS
INDICATED BY THE NAM...GOOD MOISTURE TRANSPORT MOVING ACROSS THE
FRONTAL REGION...COULD SEE HIGHER AMOUNTS. BELIEVE THE HIGHEST
AMOUNTS WILL BE NORTH OF THE I-90 CORRIDOR AS THERE WILL BE SOME
ENHANCEMENT FROM THE COASTAL LOW AS IT IS A SLOWER MOVER. SNOW WILL
BEGIN TO TAPER OFF FROM WEST TO EAST BY THE EVENING AND LAST INTO
THE OVERNIGHT HOURS.
FRIDAY...MODERATE TO HIGH CONFIDENCE.
UPPER LEVEL RIDGE WILL MOVE OVER THE REGION DURING THE DAY ALLOWING
FOR HIGH PRESSURE TO SET UP. THERE MAY STILL BE A FEW LINGERING
SHOWERS/DRIZZLE/FLURRIES FROM THE EXITING SYSTEM AS LOW LEVELS ARE
STILL QUIET DRY. HOWEVER KEPT POPS VERY LOW TO ACCOUNT FOR
UNCERTAINTY. EXPECT MAINLY LOW CLOUDS THROUGH THE DAY ON FRIDAY AS
THE MID AND UPPER LEVELS ARE QUIET DRY.
FRIDAY NIGHT - SATURDAY...MODERATE CONFIDENCE.
A STOUT TROUGH OVER THE CENTRAL CONUS WILL MAKE ITS WAY TOWARDS NEW
ENGLAND FRIDAY EVENING. THIS WILL BRING A SURFACE LOW PRESSURE SYSTEM
ACROSS THE GREAT LAKES AND INTO ONTARIO BY SATURDAY MID MORNING. THIS
SYSTEM WILL PUSH OUT A VERY STRONG COLD FRONT ACROSS SOUTHERN NEW
ENGLAND. BECAUSE OF THE STRENGTH OF THIS SYSTEM...PRESSURE GRADIENT
IS EXTREMELY TIGHT AND EXPECT WINDY CONDITIONS AREA WIDE EARLY
SATURDAY MORNING THROUGH THE EVENING HOURS. TEMPERATURES WILL START
OUT BELOW FREEZING ESP ACROSS NORTHERN MASS AND SOUTHERN NEW
HAMPSHIRE. AS PRECIP MOVES IN...A MIX PRECIPITATION WILL OCCUR
DURING THE MORNING HOURS. STILL TO MUCH UNCERTAINTY RIGHT NOW TO
PUT AMOUNTS OR EXACT LOCATION WITH THE RAIN/MIX PRECIP LINE WILL SET
UP AS WELL AS TIMING OF THE SWITCHOVER TO ALL RAIN. SINCE THIS
SYSTEM IS DEPENDING AS IT APPROACHES THE AREA...STRONG WAA WILL
MOVE IN AHEAD OF IT INCREASING 850MB TEMPS TO 8-10C. THEREFORE
EXPECT SATURDAY TO BE THE WARMEST DAY OF THE WEEK AS TEMPS WILL
REACH WELL INTO THE 50S. WITH INCREASING MOISTURE DUE TO STRONG
SOUTHERLY WINDS AND A STOUT COLD FRONT...CONVECTION IS NOT OUT OF
THE QUESTION. APPEARS THAT THE NAM IS MORE GUN-HO THEN THE GFS...AND
WITH THE MOISTURE/LIFT/AND INSTABILITY CANNOT RULE OUT THUNDER SO
HAVE INSERTED IT INTO THE FORECAST. BOTTOM LINE IS SATURDAY COULD
GET QUITE MESSY WITH VERY STRONG WINDS THROUGHOUT THE DAY...MIXED
PRECIP ACROSS THE NORTHERN TIER AND THUNDERSTORMS ACROSS THE
SOUTHERN HALF OF THE FORECAST AREA INCLUDING THE WATERS. STAY TUNE
AS THIS SYSTEM WILL EVOLVE MORE OVER THIS WEEK.
EXTENDED: SUNDAY-TUESDAY...MODERATE CONFIDENCE.
MODELS SEEM TO BE IN SOME AGREEMENT FOR THE EXTENDED WITH A UPPER
LEVEL DISTURBANCE MOVING THROUGH SUNDAY NIGHT INTO MONDAY. HIGH
PRESSURE WILL DOMINATE MONDAY NIGHT THROUGH TUESDAY.
&&
.AVIATION /15Z WEDNESDAY THROUGH SUNDAY/...
FORECASTER CONFIDENCE LEVELS...
LOW...LESS THAN 30 PERCENT
MODERATE...30 PERCENT TO 60 PERCENT
HIGH...GREATER THAN 60 PERCENT
TODAY...CONDITIONS QUICKLY DETERIORATING TO IFR FROM SW TO NE
DURING THE AFTERNOON AS SNOW OVERSPREADS THE REGION. AREAS OF LIFR
POSSIBLE LATE. AIRPORT WEATHER WARNINGS MAY BE NEEDED FOR
FROZEN/FREEZING PRECIPITATION RATES.
TONIGHT...HIGH CONFIDENCE. WIDESPREAD IFR/LIFR IN SNOW NORTH...
WITH SNOW CHANGING TO MIXED PRECIP/RAIN NEAR THE SOUTH COAST.
EASTERLY/NORTHEAST WINDS WILL INCREASE THROUGH THE OVERNIGHT
HOURS.
KBOS TERMINAL...HIGH CONFIDENCE IN TAF. SNOW DEVELOPS DURING THE
AFTERNOON WITH CONDITIONS LOWERING TO IFR BY 21Z...BUT TIMING
COULD BE OFF BY A FEW HOURS. WINDS WILL REMAIN OUT OF THE EAST
THROUGH THE TAF PERIOD.
OUTLOOK...THURSDAY THROUGH SUNDAY...
THURSDAY...MODERATE TO HIGH CONFIDENCE. EXPECT MVFR-IFR CONDITIONS
IN PERIODS OF MIXED PRECIP AND RAIN. UNCERTAINTY IN TIMING OF
TRANSITION FROM MIXED PRECIP TO ALL RAIN. E WIND GUSTS MAY REACH
25-30 KT ACROSS THE REGION FROM LATE MORNING THROUGH EARLY EVENING.
CONDITIONS MAY BRIEFLY IMPROVE TO VFR THU NIGHT ACROSS N CT/RI
INTO INTERIOR SE MA.
FRIDAY...MODERATE CONFIDENCE. MVFR CEILINGS MAY LINGER ESPECIALLY ON
THE COAST. MAY SEE MVFR VSBYS MOVE IN FROM W-E FRI NIGHT AS NEXT
SYSTEM APPROACHES.
SATURDAY...MODERATE CONFIDENCE. PERIODS OF MVFR-IFR CONDITIONS
LIKELY IN RAIN. PRECIP CHANGING OVER TO SNOW SAT NIGHT BUT WILL
TAPER OFF FROM W-E. S WIND GUSTS MAY REACH 25 KT ESPECIALLY ACROSS
THE HIGHER INLAND TERRAIN.
SUNDAY...MODERATE CONFIDENCE. MVFR CIGS/VSBYS POSSIBLE DURING THE
MORNING ACROSS RI/SE MA...OTHERWISE MAINLY VFR.
&&
.MARINE...
LIGHT WINDS THROUGH THIS MORNING...THEN EASTERLY WINDS WILL
INCREASE LATER TODAY AND ESPECIALLY TONIGHT AS A LOW-LEVEL JET
MOVES NORTH ACROSS THE WATERS. WIND GUSTS UP TO 40 KT ARE POSSIBLE
TONIGHT...ESPECIALLY ACROSS THE EASTERN COASTAL WATERS.
FORTUNATELY THE ASTRONOMICAL TIDES ARE VERY LOW AND SO COASTAL
FLOODING IS NOT ANTICIPATED.
OUTLOOK...THURSDAY THROUGH SUNDAY...
THURSDAY...E-NE WINDS WILL INCREASE...REACHING GALE FORCE AS A
GALE WARNING IS OUT FOR THE EASTERN WATERS. CONDITIONS WILL THEN
DIMINISH TO SMALL CRAFT CRITERIA THROUGH THU NIGHT. SEAS WILL BUILD
UP TO 15 FEET ON THE EASTERN OPEN WATERS AS WELL.
FRIDAY...NE WINDS GUSTING UP TO 25 KT WILL DIMINISH DURING THE
AFTERNOON...THEN VEER TO SE-S DURING FRI NIGHT AS NEXT SYSTEM
APPROACHES. SEAS REMAIN AOA 5 FT ON THE OPEN WATERS.
SATURDAY...S-SW WINDS GUSTING UP TO 30 KT. SEAS WILL BUILD UP TO 10
FT...HIGHEST ON THE SOUTHERN OUTER WATERS.
SUNDAY...WINDS VEER TO W...BUT GUSTS FORECASTED TO REACH SMALL CRAFT
CRITERIA. SEAS REMAIN AOA 5 FT ON THE OUTER WATERS.
