AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE TAUNTON MA
959 AM EST SAT DEC 5 2009

.SYNOPSIS...
LOW PRESSURE DEVELOPING OFF THE SOUTHEAST COAST THIS MORNING WILL
MOVE RAPIDLY NORTHEAST TODAY AND INTENSIFY DRAMATICALLY TONIGHT AS
IT PASSES SOUTHEAST OF NANTUCKET. THIS SYSTEM WILL GIVE A GOOD PORTION
OF SOUTHERN NEW ENGLAND IT/S FIRST SIGNIFICANT SNOWFALL OF THE SEASON.
THIS LOW WILL QUICKLY MOVE AWAY ON SUNDAY AND BE REPLACED BY HIGH
PRESSURE THROUGH MONDAY. WEAK LOW PRESSURE MAY AFFECT SOUTHERN NEW
ENGLAND MONDAY NIGHT. ANOTHER FAST MOVING LARGE LOW PRESSURE SYSTEM
WILL IMPACT THE REGION MIDWEEK WITH A MIXTURE OF PRECIPITATION AND
WIND.

&&

.NEAR TERM /UNTIL 8 PM THIS EVENING/...
00Z VERSIONS OF THE UKMET GGEM/RGEM HAD THE .01 INTO SNE NR 12Z THIS
MORNING. 06Z NAM CSI BANDING TOOL HAD THE SYM STABILITY MEASURABLE
RAIN SIGNAL SPOT-ON AT 12Z AND IT SHOWS A QUICK 3 HR CLUSTER OF
SHOWERS MOVING THRU SE NEW ENGLAND ENDING BY 16Z THEN AWAITING THE
MAIN EVENT WHICH FOLLOWS AN HR OR 2 LATER. THIS ONE THE 03Z SREF DID
NOT HAVE NO PREDICTION SYSTEM IS PERFECT.

HAVE HAD BRIEF R/S MIX HIGH TERRAIN N CENTRAL CT ARD 9AM. AT 10 AM
TEMPS...STILL CREEPING UP DESPITE RAIN.

TO CLARIFY...BL WARMTH CONTS TO BE A PROBLEM FOR R TO SNOW THRU
19Z... AND THEREAFTER WE HAVE TRANSITIONED SLIGHTLY FASTER...ESP HIGH
TERRAIN AND LARGEST PRES FALLS STILL E OF THE CAROLINAS... ABOUT 4 MB
IN 3 HRS.

THE PRODUCTS ARE UPDATED AGAIN AT 955 AM USING THE 12Z NAM...INCLUDING
PARTIAL THICKNESSES AS WELL NAM 2M TEMPS BLENDED FROM 19Z-01Z WHICH
YIELDS A SLIGHTLY FASTER CHANGE TO SNOW IN THE HIGH TERRAIN OF
CT/CENTRAL MA THIS AFTN. WE BOOSTED THE WIND SLIGHTLY THIS AFTN.

REMAINDER BLO FROM THE 4AM DISCUSSION.

LOW PRESSURE WILL MOVE UP THE EAST COAST TODAY AND TONIGHT AND SHOULD
DELIVER SOUTHERN NEW ENGLANDS FIRST SIGNIFICANT SNOWFALL OF THE
SEASON. HOWEVER...THERE ARE SEVERAL FACTORS INVOLVED THAT MAKE THIS A
LESS THAN HIGH CONFIDENCE FORECAST. MUCH OF THE FORECAST WAS DERIVED
FROM A BLEND OF THE NAM/GFS/ECMWF WITH SEVERAL ADJUSTMENTS MADE TO QPF
AND TEMPS. THE MAIN CONCERNS REVOLVE AROUND BOUNDARY LAYER
TEMPERATURES...AS WELL AND WHERE EXACTLY THE HEAVIEST PRECIPITATION
WILL FALL AND WHEN. IT APPEARS AS THOUGH THE MAIN ACTION WILL BEGIN
LATER THIS AFTERNOON AND ESPECIALLY THIS EVENING.

LIGHT PRECIPITATION OVERSPREADING SOUTHERN NEW ENGLAND FROM SOUTH TO
NORTH THIS MORNING WILL BE IN THE FORM OF RAIN DUE TO RELATIVELY
WARM TEMPERATURES AT AND NEAR THE SURFACE. HOWEVER...HIGHEST
ELEVATIONS OF THE INTERIOR MAY START AS SNOW OR A RAIN SNOW MIX. AS
HEAVIER PRECIPITATION DEVELOPS OVER THE REGION THIS AFTERNOON...SNOW
LEVELS WILL DROP AND ALLOW FOR SNOW TO BEGIN ACCUMULATING AT HIGHER
ELEVATIONS. THE COASTAL PLAIN AND OTHER LOWER ELEVATION LOCATIONS
WILL LIKELY REMAIN ALL RAIN THROUGH THE AFTERNOON UNTIL GREATER
VALUES OF UPWARD VERTICAL MOTION ARRIVE...WHICH SHOULD BE TOWARD
EVENING OR DURING THE EVENING. OF COURSE...THE TIMING COULD VARY A
BIT...SO ATTENTION WILL HAVE TO BE PAID TO SUBSEQUENT FORECAST
UPDATES. A VERY CHANGEABLE WEATHER SITUATION WILL LIKELY DEVELOP
TODAY...IT MAY TAKE A SHORTER AMOUNT OF TIME FOR SOME LOCATIONS TO
FLIP TO SNOW...WHILE IT TAKES A BIT LONGER AT OTHERS DUE TO MESOSCALE
ASCENT DISTRIBUTION.

WE HAVE ISSUED WINTER WEATHER ADVISORIES FOR THE WESTERN AND CENTRAL
PORTIONS OF THE FORECAST AREA STARTING MID AFTERNOON.

&&

.SHORT TERM /8 PM THIS EVENING THROUGH 6 PM SUNDAY/...
A WINTER WEATHER ADVISORY IS IN EFFECT FOR MUCH OF SOUTHERN NEW
ENGLAND FOR TONIGHT...EXCEPT FOR SOUTHERN NH AND IMMEDIATE COASTAL
LOCATIONS OF SE MASS AND RI. UPWARD VERTICAL MOTION SHOULD BE
CRANKING PRETTY GOOD BETWEEN 00Z AND 06Z. THIS WILL RESULT IN A
TRANSITION FROM RAIN TO SNOW FROM WEST TO EAST...AND IT MAY OCCUR
VERY QUICKLY BETWEEN 00Z AND 03Z ON THE COASTAL PLAIN AS LONG AS
STRONG OMEGA DEVELOPS. THE EXACT AMOUNT OF SNOWFALL WILL DEPEND ON
QPF...WHERE THE BEST OMEGA ENDS UP BEING...AND THE TEMPERATURE
PROFILES.

SOME OF THE GUIDANCE IS TRYING TO CLOSE OFF THE MID LEVEL LOW FOR A
TIME THIS EVENING...AND THIS MAY INCREASE SNOWFALL RATES QUITE
STOUTLY AS MESOSCALE BANDING TRIES TO TAKE SHAPE...ESPECIALLY ACROSS
EASTERN ZONES. THIS COULD ADD A BIT MORE TO SNOWFALL TOTALS THERE.
FOR NOW...WE THINK THE HIGHER ELEVATIONS OF CENTRAL MASS AND CT WILL
DO BEST IN TERMS OF SNOW...BUT THIS IS THE TYPE OF SYSTEM THAT COULD
THROW A FEW CURVEBALLS. AT THIS TIME...WE ARE FORECASTING A GENERAL 2
TO 5 INCHES OF SNOWFALL...WITH 3 TO 6 IN THE HIGHER ELEVATIONS. IF
MESOSCALE BANDING WERE TO GET GOING THIS EVENING...THEN HIGHER
SNOWFALL TOTALS COULD BE EXPECTED...EVEN ON THE COASTAL PLAIN.
EASTERN MASS/INTERIOR SE MASS/RHODE ISLAND LOOK PARTICULARLY
INTRIGUING WITH RESPECT TO THE POTENTIAL FOR MESOSCALE BANDING AND
WE/LL HAVE TO KEEP AN EYE OUT FOR THAT THIS EVENING. COASTAL FRONT
ENHANCEMENT MAY BE ANOTHER FACTOR TO CONSIDER AS WELL. THERE/S A LOW
PROB THAT SOMEONE SEES LOW-END WINTER STORM WARNING CRITERIA SNOWFALL
OUT OF THIS...BUT THOSE AREAS ARE TOO DIFFICULT TO PINPOINT AT THIS
TIME. IN ADDITION...SOUTHERN NEW HAMPSHIRE ISN/T COMPLETELY OUT OF
THE WOODS. THEIR ADVISORY CRITERIA IS A BIT HIGHER THAN THE REST OF
SNE SO DIDN/T ISSUE ONE AT THIS TIME...BUT THEY MAY NEED TO BE
UPGRADED LATER IF IT LOOKS FOR CERTAIN THAT HIGHER QPF VALUES WILL
MAKE IT UP THERE.

SNOW MAY FALL HEAVY AT TIMES THIS EVENING. SINCE THE BOUNDARY LAYER
TEMPERATURES WILL BE NEAR FREEZING...SNOW MAY ACCUMULATE ON TREES AND
WIRES CAUSING BRANCH BREAKAGE AND THE POTENTIAL FOR SCT POWER OUTAGES.

NORTHERLY WINDS WILL BECOME AN ISSUE ON THE CAPE AND ISLANDS WITH
GUSTS UP TO 50-55 MPH POSSIBLE AS THE STORM CONTINUES TO INTENSIFY.

SUNDAY...QUIETS DOWN WITH A NICE LOOJK TO THER LANSCAPE WITH FRESH
SNOW COVER. A BIT CHILLER THAN TODAY.

&&

.LONG TERM /SUNDAY NIGHT THROUGH FRIDAY/...
ACTIVE PATTERN CONTINUES INTO NEXT WEEK. LEFT OVER SNOW SHOWERS MAY
LINGER UNTIL 13Z OR 14Z OVER THE CAPE AND NANTUCKET. OTHERWISE...BECOMING
MOSTLY SUNNY AND BLUSTERY ON SUN. EXPECT MON TO START OUT DRY BUT
THEN BECOME MOSTLY CLOUDY WITH CHANCE SNOW SHOWERS ACROSS NORTHERN
ZONES AS SHORT WAVE TROF RAPIDLY APPROACHES IN FAST ZONAL FLOW. THERE
MAY BE A WEAK SURFACE LOW OR TROUGH REFLECTION MON EVENING.

LOOKS LIKE ENOUGH MOISTURE AND DYNAMICS TO WARRANT A LOW CHANCE OF
SNOW SHOWERS IN NORTHERN ZONES FOR MON EVE. THIS APPROACH SUPPORTED BY
SREF .01 PROB.

CONSIDERABLE COLD AIR IN PLACE AHEAD OF NEXT SIGNIFICANT EVENT WED
AND WED NIGHT WHEN EXPECT STRONG OVERRUNNING AND START OF PRECIPITATION AS
SNOW MOST LOCATIONS. MOST MEDIUM RANGE MODEL OUTPUT BRINGS PRIMARY
SURFACE LOW ACROSS EASTERN GREAT LAKES WITH DEVELOPING TRIPLE POINT
LOW THAT TRACKS RIGHT ACROSS SOUTHERN NEW ENGLAND. LOW LEVEL JET OF
60+ KT FROM SE ACROSS TIGHT TEMPERATURE GRADIENT ACCOMPANIED BY
SUBTROPICAL SOURCE OF MOISTURE WILL LIKELY PRODUCE COPIOUS AMOUNTS OF
PRECIPITATION. ATTM...THINKING THERE WILL BE A BURST OF
SNOW...PERHAPS A FEW INCHES ON THE FRONT END AND THEN A CHANGE TO
SLEET/FREEZING RAIN AND THEN MOSTLY RAIN. MAY HAVE A MORE SIGNIFICANT
SNOW ACCUMULATION ACROSS SW NH...AND IF TRIPLE LOW FAR ENOUGH
EAST...THEN LOW LEVEL COLD AIR COULD HANG IN AND CAUSE A SNOW TO
SLEET TO FREEZING RAIN SCENARIO ACROSS SW NH AND NW MA. HAVE CAPPED
POPS AT LIKELY CATEGORY DUE TO LENGTH OF TIME BEFORE MID WEEK EVENT
AND INHERENT UNCERTAINTY WITH SUCH LEAD TIMES. ALSO HELD BACK THE
ONSET A LITTLE SINCE EXPECT A LOT OF LOW LEVEL DRY AIR THAT WILL NEED TO
BE OVERCOME AT THE OUTSET.

THERE IS A CHANCE THAT SOUTH WINDS MAY REACH WIND ADVISORY CRITERIA
OVER THE CAPE AND ISLANDS SOMETIME WED NIGHT...BUT THIS DEPENDS ON
DETAILS THAT ARE HARD TO RESOLVE THIS FAR OUT.

A SHIFT IN THE TRACK AND TIMING OF TRANSFER OF ENERGY TO SECONDARY
LOW COULD RESULT IN FAIRLY DRAMATIC CHANGES TO THE FORECAST...
ESPECIALLY WITH REGARD TO PTYPE AND WIND THREATS.

WE TURN COLD AGAIN AFTER THE MID WEEK EVENT. KEPT CHANCE POPS GOING
IN NORTHERN ZONES ON THU UNTIL THE PASSAGE OF THE UPPER TROF.

.AVIATION /15Z SATURDAY THROUGH WEDNESDAY/...
