AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE TAUNTON MA
104 AM EST TUE FEB 16 2010
.SYNOPSIS...
LOW PRESSURE OVER DELAWARE INTENSIFIES AS IT MOVES NORTHEAST TO NEAR
NEW YORK CITY EARLY TUE...THEN TRACKS ACROSS SOUTHEAST MASSACHUSETTS
OR CAPE COD LATE TUE AFTERNOON. THIS WILL BRING ACCUMULATING SNOW TO
SOUTHERN NEW ENGLAND TUESDAY...ESPECIALLY AWAY FROM THE SOUTH COAST.
GUSTY AND SEASONABLE CONDITIONS SHOULD FOLLOW THROUGH THE WEEKEND
WITH FLURRIES OR WIDELY SCATTERED SNOW SHOWERS POSSIBLE LATE
WEDNESDAY AND AGAIN LATE FRIDAY.
&&
.NEAR TERM /UNTIL 6 AM THIS MORNING/...
HAVE DONE A QUICK REVIEW OF THE 00Z NAM AND ITS MASS FIELDS ARE VERY
CLOSE TO THE 15/12Z ECMWF...WITH MID LEVEL CIRCULATION TRACKING
ACROSS CAPE COD AND ISLANDS 00Z WED AND SURFACE LOW TRAVERSING THE
SOUTHERN NEW ENGLAND COASTLINE. DESPITE THE MASS FIELDS IN GOOD
AGREEMENT ON TIMING AND AMPLITUDE...THE 00Z NAM HAS TWICE THE AMOUNT
OF QPF THAN THE 12Z ECMWF...WITH OVER AN INCH OF LIQUID OVER PORTIONS
OF EASTERN MA AND NORTHERN RI ENDING 06Z WED. MEANWHILE THE 12Z ECMWF
HAS STORM TOTAL LIQUID QPF OF 0.4 TO 0.6 INCHES. THE 21Z SREF SUPPORTS
THE LIGHTER 12Z ECMWF.
BOTH THE 00Z NAM AND 12Z ECMWF OFFER SOME BRIEF MODEST SYNOPTIC SCALE
LIFT FROM 18Z-00Z BUT BOTH MODELS AGREE THAT THE MID LEVEL
CIRCULATION DOESN/T OFFER MUCH ATLC INFLOW/MOIST COLD CONVEYOR BELT
UNTIL LATE TUE NIGHT AS SYSTEM APPROACHES NOVA SCOTIA. THEREFORE THE
LACK OF GOOD ATLC INFLOW AND SHORT DURATION SUPPORTS THE LIGHTER QPF
FROM THE 12Z ECMWF AND 21Z SREF.
THEREFORE LEANING TOWARD A WIDESPREAD ADVISORY EVENT WITH PRELIMINARY
SNOW TOTALS OF 1-3 INCHES SOUTH COAST NORTHWARD TO PVD-MARSHFIELD /AS
RAIN-SNOW APPROACHES THIS AREA/ AND 3-6 INCHES ELSEWHERE WITH HIGHEST
AMOUNTS NORTHEAST MA INCLUDING THE GREATER BOSTON AREA AND POSSIBLY
INTO HILLSBORO COUNTY OF NH...AS SYSTEM BEGINS TO INTENSIFIES AS IT
MOVES OFFSHORE THIS EVENING.
HOWEVER...WE WILL AWAIT 00Z GFS/UKMET AND CANADIAN MODELS BEFORE
MAKING A DECISION.
MEANWHILE LOW PRES DEVELOPING OVER COASTAL DE AT 03Z WITH LEADING
EDGE OF SNOW AT MMK AND SNC ACROSS SOUTHERN CT...AS WARM CONVEYOR
BELT STREAMS NORTHWARD UP THE COAST. 21Z SREF DOING A GOOD JOB WITH
ONSET OF SNOW. BY 06Z SNOW SHOULD BE FROM SPRINGFIELD MA EXTENDING
SOUTHEAST TO WST AND BID /POSSIBLY RAIN OR A MIX/. BY 09Z SHOULD BE
SNOWING ALL AREAS EXCEPT EASTERN MA WHERE SNOW SHOULD OVERSRPEAD THE
AREA 10Z/11Z. THIS INITIAL BURST OF WARM ADVECTION SNOWS THIS MORNING
WILL ONLY GENERATE 1-3 INCHES OF SNOW...WITH HEAVIER PRECIPITATION
18Z-00Z. AS MENTIONED ABOVE LOOKS LIKE RAIN-SNOW LIFTS NORTHWARD TO A
PVD-GHG LINE LATE THIS MORNING AND EARLY AFTERNOON. THEN THE RAIN-
SNOW LINE COLLAPSES SOUTH AS SURFACE LOW HEADS FOR THE CAPE AND WINDS
BACK TO THE NNE WITH COLUMN COOLING AND PRECIP CHANGING BACK TO ALL
SNOW.
&&
.SHORT TERM /6 AM THIS MORNING THROUGH 6 PM WEDNESDAY/...
THE SNOW SHOULD DIMINISH AFTER ITS INITIAL DECENT BURST AS A DRY SLOT
TRIES TO MOVE NORTHWARD INTO THE REGION BEFORE THE UPPER LVL CLOSED
LOW CAN TURN THE DEEP FLOW EASTERLY AND SHUT DOWN THE DRYING.
THIS IN MIND...WITH TEMPS PROBABLY REACHING 32 AND KNOWING THAT FEB
SUN WHILE UNSEEN CAN STILL HEAT THE PAVEMENT A BIT MORE THAN THE AIR
TEMP...CAUSING SOME MELTING ON CONTACT...DECIDED TO CUT BACK THE SRN
PART OF THE WATCH...ESP CT RI.
THERE WILL BE RENEWED CONVECTIVE TYPE PCPN IN ERN MASS LATE MORNING
AND THEN CURLING NWWD IN THE AFTN ACROSS NE MASS AND SE NH WHERE A
MORE GENERAL SNOWFALL SHOULD DEVELOP.
DIDNT WANT TO CANCEL THE WATCH YET FOR OWD MQE BOS BUT CONFIDENCE
THERE IS LOWER THAN AVG FOR WARNING AMTS. OUR SNOW GRAPHIC HAS SPOT 6
PLUS INCHES DOWN THERE IN THE VCNTY OF HIGHER ELEVATIONS.
BEST CHC FOR 8 INCH AMTS VCNTY ORH TO LWM MHT AFN REGION.
NEXT SHIFT HAS THE OPPORTUNITY TO CONVERT.
THIS HOLDING BACK ON A CONVERSION SHOULD BE AN INDICATOR TO ALL
CUSTOMERS OUR UNCERTAINTY REGARDING SNOW AMOUNTS...ESPECIALLY THE
AFTN DAYLIGHT HOURS WITH TEMPS NEAR FREEZING. TREATED/PLOWED ROADS
AT TIMES DURING THE AFTN IN THE WATCH AREA MAY BE JUST WET...AFTER
THE INITIAL MORNING BURST OF SNOWFALL.
NOT ANTICIPATING A BLOCKBUSTER EVENT DUE TO LACK OF SUBSTANTIAL
PROLONGED 850 INFLOW AND SFC TEMPS ARE LIKELY TO PERMIT PAVEMENT
MELTING FOR AT LEAST A PORTION OF THE DAYLIGHT HOURS TUESDAY.
IN GENERAL THEN...WE ARE LOOKING AT 18 HOURS OF INTERMITTENT SNOW
TAPERING TO FLURRIES EARLY WED.
FORECAST INGREDIENTS BELOW INCLUDING SOME OF THE SCIENCE
12Z NCEP COLLAB: 6+ MOST CWA RTE 2 NORTHWARD DIPPING DOWN TO ORH BOS
AREA. LESS THAN 4 INCHES PVD TO PYM SWD...A PORTION OF THAT HOWEVER
IN OR JUST PRIOR TO THE WED MORNING RUSH. THIS
15Z SREF MEAN SNOWFALL: 8-10 AFN EAST. 6-8 LWM JUST N OF ORH TO ORE
NORTHWARD TO THE 8+ REGION... 4+ NE CT TO NW HILLS RI BOS NORTHWARD...
LESS ELSEWHERE. SREF SNOW PROBS CAN SHOW SIGNIFICANT ERROR ON THE
EDGES WHERE ENSEMBLE SPREAD AND PTYPE/SFC MELTING ON CONTACT PLAY A
ROLE. RIGHT NOW...WE ARE MOST CONFIDENT IN S NH BUT WANTED FORECASTERS
TO HAVE ANOTHER LOOK FOR THE TUE AFTN EVENING SIGNIFICANT SNOWFALL.
SREF HAS 20 PCT 12 HR PROB 8 INCHES NE MA JUST N OF BOS.
12Z QG FORCING/INSTABILITY: PROGRESSIVELY INTENSIFYING SLOWLY AND
PRIME NEWD PASSAGE THRU OUR AREA 16ZT-02Z WED AND ALMOST MIRRORED BY
BOTH NAM/GFS. FAIRLY LARGE 6-6.5C/KM MOIST LAPSE RATE INSTABILITY
BOTH MODELS.
12Z FGEN-BANDING: 2 BANDS..BOTH LOOK MINOR TO ME. ONE IN THE MORNING
MAYBE A BIT BETTER BANDING APPEARS LATE DAY RI AND E MA...FAVORING
SE 2/3RDS OF THE FA. THIS HAS QUITE A BIT OF UNCERTAINTY.
SNOW GROWTH: SPOT CHECKED LOOKS GOOD IN SNH FOR SEVERAL HOURS TUE
AFTN/EVE. THIS TOO HAS UNCERTAINTY AND APPEARS TO BE SHIFTING N
WITH MODEL RUNS.
SNOW LIQUID RATIOS...FCST WAS FOR 12 OR 13 TO 1 BUT THAT LOOKS A
LITTLE ON THE FLUFFY SIDE TO ME...ESPECIALLY E MA. ALSO AN
UNCERTAIN PART OF THE ULTIMATE FCST AMOUNTS.
MIXED PCPN AND ABV FREEZING TEMPS: WILL BE SOME SORT OF PLAYER ALONG
INTERSTATE 95 BOSTON SWWD TO WESTERLY SO FCST AMOUNTS NOT SET IN STONE.
15Z SREF 24 HR QPF .25 BDL TO .6 BOS ORH AFN NEWD WITH 20 PCT 1 INCH
LWM BVY NEWD BY 09Z WED.
12Z GEFS 24 HR QPF .2 BDL TO .6 AFN EEN NEWD ENDING 12Z WED. NOT
LOOKING AT GEFS PARALLEL BECAUSE 00Z 06Z 12Z VSNS N/A FROM MY WEB
LOCATION AND IT WAS NOT GOOD LAST STORM.
ENSEMBLE QPF INFORMATION INTERP: THINK WE SEE ENOUGH INFORMATION IN
ENSEMBLES SUGGESTING PLAYING IT CONSERVATIVE FOR MA PIKE REGION SOUTH
WITH BEST CHC WARNING AMTS N OF RTE 2.
SREF AS WELL AS ECMWF HAS SHOWN SOME CONSISTENCY FROM THE MID ATLC
INTO SNE WITH THE TYPICAL CONSERVATIVE BIAS IN TIME MORE DISTANT FROM
THE EVENT...SHOWING A A GENERAL EVOLUTION FOR 4 TO 10 INCH INTERIOR
SNE THRU 09Z WED... HEAVIEST IN NORTH MA AND S NH.
HTTP:/WWW.HPC.NCEP.NOAA.GOV/WWD/IMPACTGRAPHICS/ ALL LOWER CASE.
MEAN AREAL S/IP SERVES AS A GOOD BASE CHECK ON TRENDS AND AXIS OF MAX
SFALL NOT ACCOUNTING FOR LOCAL EFFECTS/SNOWGROWTH AND UNDERSTANDING
THAT PTYPE ISSUES ON THE EDGES AND TIMING AREAL COVERAGE SPREAD
CAN RESULT IN SIGNIFICANT EDGE ERRORS.
TEMPS ARE 12Z NCEP 50/50 BLEND.
WINDS ARE 12Z NCEP 50/50 BLEND.
GUSTS ARE NAM GUST ALG OFF NAM MXG HTS.
TUE NIGHT...MID LVL LOW WILL BE MOVING NE FROM THE BENCHMARK TUE
EVENING. BAND OF MOISTURE IN THE COMMA HEAD WILL LIKELY PRODUCE A
PERIOD OF LIGHT SNOW THROUGH TUE EVENING BEFORE ENDING FROM
NORTHWEST TO SOUTHEAST OVERNIGHT.
&&
.LONG TERM /WEDNESDAY NIGHT THROUGH MONDAY/...
WEDNESDAY TO MONDAY PERIOD IS DOMINATED BY MARITIME LOW PRESSURE WITH
CYCLONIC FLOW ACROSS NEW ENGLAND. INDIVIDUAL SHORTWAVES ROTATE
THROUGH THE FLOW ACROSS THE REGION. TIMING CAN BE DIFFICULT THIS FAR
OUT BUT LATER WEDNESDAY AND LATER FRIDAY LOOK FAVORED AT THIS TIME.
TIME SECTIONS SHOW ALMOST CONTINUOUS MOISTURE AT AND BELOW 850 MB
THROUGH SUNDAY. DEEPER MOISTURE LATE WEDNESDAY/THURSDAY AND AGAIN
LATE FRIDAY/FRIDAY NIGHT ESPECIALLY OVER NORTHERN MASS AND SOUTHERN
NH. LITTLE IN THE WAY OF LIFT IN THE PRECIPITATION GENERATION
ZONE...ONLY THE CYCLONIC FLOW SEEMS TO BE WORKING IN FAVOR OF ANY
RAIN/SNOW.
WILL GO WITH CLOUDY PERIODS DURING THE PERIODS OF DEEPER MOISTURE
BUT LIMIT ANY POPS TO AROUND 15 PCT AT BEST. SUSPECT THE REMAINDER
OF THE FORECAST PERIOD MAY FEATURE MORE SKY COVER THAN CURRENTLY
ADVERTISED BUT WILL STAY CLOSER TO GUIDANCE IN THOSE INTERIM PERIODS.
TEMPERATURES ARE A BLEND OF MOS AND HPC GUIDANCE.
