AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE TAUNTON MA
416 AM EDT MON APR 4 2016
.SYNOPSIS...
CLIPPER LOW SWEEPING S OF NEW ENGLAND TODAY WILL YIELD ANOTHER
OPPORTUNITY FOR ADVISORY-LEVEL ACCUMULATING SNOWS EARLY THIS
MORNING INTO THIS EVENING. DRIER BUT COOLER WEATHER EXPECTED
TUESDAY AND WEDNESDAY...WITH MORE WET WEATHER LIKELY BY THE END OF
THE WORK WEEK.
&&
.NEAR TERM /UNTIL 6 PM THIS EVENING/...
HIGHLIGHTS...
* MESSY MORNING COMMUTE WITH ACCUMULATING SNOWS ON ROADWAYS AND
SIGNIFICANTLY REDUCED VISIBILITIES AT TIMES
* STORM TOTAL 2 TO 4 INCH ACCUMULATIONS WITH LOCALLY HIGHER
AMOUNTS UP AROUND 6 INCHES ACROSS CENTRAL AND N MASSACHUSETTS
ESPECIALLY ACROSS THE HIGH TERRAIN
OVERVIEW...
CLIPPER LOW SWEEPING S NEW ENGLAND WILL BRING A LIGHT TO MODERATE
SNOW EVENT BEGINNING EARLY MORNING PRIOR TO DAYBREAK AND PERSISTING
INTO LATE AFTERNOON. WINTER WEATHER ADVISORIES REMAIN IN EFFECT.
EARLY MORNING PRIOR TO DAYBREAK TO MIDDAY...
BEGINNING EARLY THIS MORNING PRIOR TO DAYBREAK...ISENTROPIC UPSLOPE
OVER-RUNNING EVENT OF WARM-MOIST AIR OVER A COLD DOME OF AIR ACROSS
THE REGION. FRONT-END THUMP OF PRECIPITATION SUBSEQUENT OF STRONG
S/SW LOW LEVEL WINDS CONVERGENT AHEAD OF THE CLIPPER LOW SWEEPING
E/SE OF S NEW ENGLAND. BENEATH THE RIGHT REAR QUADRANT OF THE UPPER
LEVEL JET...DEEP-LAYER LIFT AND DECENT FRONTOGENESIS. EXPECT SOME
ROUGHLY NW-SE SNOW BANDING MORE INTENSE SNOWFALL WITHIN THE OVERALL
PRECIPITATION SHIELD. CAN ALREADY SEE THIS ON LATEST RADAR RETURNS.
EXCEPT FOR THE IMMEDIATE S-COAST MOST OF THE AREA WILL START OFF AS
SNOW. COLDER TEMPERATURES WILL ALLOW SNOW TO ACCUMULATE EASILY ON
ROADWAYS MAKING FOR A MESSY MORNING COMMUTE BEGINNING AROUND 4 TO 6
AM W TO E IN ADDITION TO REDUCED VISIBILITIES. TOWARDS MIDDAY AS WE
GRADUALLY WARM THE RAIN-SNOW LINE WILL LIFT N AS THE ABILITY FOR
SNOW TO STICK ON SURFACES DIMINISHES. ROADWAYS LIKELY TO TURN WET AS
WE WARM TO AND ABOVE THE FREEZING MARK S TO N.
LOOKING AT A GENERAL 2 TO 4 INCHES WITH LOCALLY HIGHER AMOUNTS UP
TO 6 INCHES. HIGHER AMOUNTS AROUND CENTRAL AND N MASS ESPECIALLY
ATOP HIGH TERRAIN OF BERKSHIRES AND WORCESTER HILLS. LOWEST ACCUMS
ACROSS THE S-TIER OF COUNTIES IN RI AND MASS. IMPACTS WILL BE
SIGNIFICANT DURING THE MORNING RUSH WITH SNOW ACCUMULATIONS ON
ROADWAYS WITH FORECASTED TEMPERATURES IN THE 20S...NOT TO MENTION
REDUCED VISIBILITIES.
MIDDAY TOWARDS EVENING...
AS THE FORWARD THUMP OF SNOW PROGRESSES E/NE WILL BEGIN TO SEE THE
SECOND WAVE OF FORCING PARENT WITH STRETCHED MID-LEVEL VORTEX ENERGY
AND ACCOMPANYING COLD FRONT TO THE N OF THE CLIPPER LOW. SUBSEQUENT
LIFT / FRONTOGENETICAL FORCING ESPECIALLY THRU SNOW GROWTH REGIONS
AND BENEATH GOOD VENTING ALOFT...COMBINED WITH SHALLOW COLD AIR AT
THE SURFACE SWEEPING IN FROM THE N. LIGHT TO MODERATE SNOW CONTINUES
DURING THE AFTERNOON HOURS TRANSITIONING NW TO SE...ESPECIALLY ALONG
AND S OF THE MASS PIKE. BOSTON METRO AREA MAY NOT SEE A LULL INBETWEEN
BUT REMAIN IN A PERSISTENT ALL-SNOW EVENT.
TEMPERATURES CRITICAL TO WHICH DURING THIS TIMEFRAME WILL BE AROUND
FREEZING LIMITING THE EFFECTIVENESS IN SPOTS OF SNOW ACCUMULATION.
COMPLICATED GIVEN THE UNCERTAINTY AS TO THE INTENSITY OF SNOWFALL
WITH THE POTENTIAL FOR SW TO NE BANDING. OVERALL MAY BE DEALING WITH
AN ADDITIONAL 1 TO 2 INCHES. COMPLEXITIES AND UNCERTAINTIES NOT TO
MENTION HAVING TO INTERPRET HOW WELL ROADWAYS HAVE BEEN TREATED.
FINAL NOTES...
AGREE WITH THE PREVIOUS FORECASTER. INTANGIBLES AND UNCERTAINTIES PER
COMPLICATING FACTORS SUCH AS THE INTENSITY OF SNOWFALL PARENT WITH
SURFACE TEMPERATURES. DIFFICULT TO FORECAST EXACT AMOUNTS AND
TRICKY TO KNOW EXACTLY WHERE THE HEAVIEST SNOW WILL BE OBSERVED.
BUT AN ANALYSIS OF ANALOGS AND HIGH-RES GUIDANCE...AN OVERALL 3 TO
6 INCH EVENT IS EXPECTED MAINLY N OF THE S ROW OF COUNTIES ACROSS
CT/MA/RI. LOCALLY HIGHER AMOUNTS ARE POSSIBLE MAINLY ALONG AND N
OF THE MASS PIKE...ESPECIALLY HIGH TERRAIN.
&&
.SHORT TERM /6 PM THIS EVENING THROUGH 6 AM TUESDAY/...
HIGHLIGHTS...
* ACCUMULATING SNOWS LINGER ACROSS SOUTHEAST NEW ENGLAND MAKING
FOR HAZARDOUS TRAVEL CONDITIONS
* SHOULD ROADWAYS REMAIN WET...A FLASH FREEZE POSSIBLE TOWARDS
EVENING AND OVERNIGHT
DISCUSSION...
ELONGATED CLIPPER LOW DRAGS OUT TO SEA TOWARDS MORNING BEHIND WHICH
N FLOW PREVAILS DRAWING COLDER AIR S. WET UNTREATED ROADWAYS WOULD
POTENTIALLY FREEZE AND RATHER QUICKLY AS THE SHALLOW COLD AIR MASS
WILL BE ADVECTING S DURING THE AFTERNOON DROPPING TEMPERATURES INTO
THE MID TO UPPER 20S BY NIGHTFALL. LOOKING AT LOWS DOWN INTO THE
TEENS.
MEANWHILE SNOW WILL LINGER ACROSS SE NEW ENGLAND MAINLY DUE TO MID
LEVEL FORCING AND CONTINUED VENTING ALOFT...BUT ALSO PERHAPS UNDER-
GOING OCEAN ENHANCEMENT PER COLDER AIR PUSHING S ENHANCING A SHALLOW
UNSTABLE BOUNDARY LAYER PROFILE AND UNIFORM N FLOW. COULD SEE AN
ADDITIONAL INCH OF SNOW ACCUMULATION PRIOR TO MORNING.
&&
.LONG TERM /TUESDAY THROUGH SUNDAY/...
HIGHLIGHTS...
* HIGH PRESSURE LATE TUESDAY INTO WEDNESDAY
* ACTIVE WEATHER PATTERN BEGINNING THURSDAY INTO NEXT WEEK
* UNSEASONABLY COLD THROUGH WED...THEN MODERATING THU AND FRI
OVERVIEW...
OVERALL 00Z MODELS SYNOPTIC FIELD IS IN GOOD AGREEMENT FOR THIS
FORECAST. STILL A LOT OF UNCERTAINTY IN REGARDS TO THERMAL
FIELDS...TIMING AND STRENGTHEN OF EACH SYSTEM BEGINNING THURSDAY TO
DAY 7. QUICK MOVING LOW TODAY WILL BE OFFSHORE BY TOMORROW FOLLOWED
BY ARCTIC HIGH PRESSURE FOR WEDNESDAY. FIRST FRONTAL WAVE WILL MOVE
THROUGH THE REGION ON THURSDAY AS ANOMALOUS UPPER LEVEL TROUGH OF 3
SD BELOW NORMAL DEVELOPS OVER THE NORTHEAST. STRONG RIDING OUT TO
THE WEST WILL CUTOFF THE UPPER LEVEL LOW IN RESPONSE WHICH WILL
WOBBLE AND ROTATE SEVERAL MORE SHORTWAVE OVER THE NORTHEAST INTO
NEXT WEEKEND. RIGHT NOW HAVE HIGHEST CONFIDENCE THAT BELOW NORMAL
TEMPS WILL OCCUR ON TUESDAY INTO WEDNESDAY WITH NEAR RECORD LOW
TUESDAY NIGHT/WED AM. ALSO BELIEVE TEMPS WILL WARM BACK TO
SEASONABLE BY THURSDAY AS RAIN MOVES THROUGH THE REGION. LOW
CONFIDENCE ON TIMING AND P-TYPE AFTER THURSDAY FOR EACH WAVE THAT
MOVES THROUGH THE FLOW.
DAILIES...
TUESDAY INTO WEDNESDAY...HIGH CONFIDENCE.
QUICK MOVING LOW PRESSURE SYSTEM WILL BE OFFSHORE BY TUESDAY
MORNING. ON THE BACK SIDE OF THE SYSTEM...PERSISENT NORTHERLY FLOW
COMBINED WITH MOISTURE AND Q-G FORCING ALOFT ANTICIPATE OCEAN EFFECT
SNOW TO CONTINUE ACROSS PLY AND THE CAPE INTO TUESDAY MORNING. THE
NORTHERLY TRAJECTORY APPEARS TO BREAK UP OR SWITCH TO A MORE
NORTHWEST COMPONENT BY 15-18Z. HOWEVER WITH OVER 300 J/KG OF LI CAPE
WE COULD SEE A QUICK INCH AROUND THE MORNING COMMUTE ON TUESDAY ESP
ACROSS THE CAPE AND ROUTE 3 CORRIDOR.
OTHERWISE ARCTIC HIGH PRESSURE WILL APPROACH THE NORTHEAST TUESDAY
AFTERNOON BRINGING BELOW NORMAL TEMPS BOTH TUESDAY AND ON WEDNESDAY.
TUESDAY NIGHT TEMPS COULD MAKE A RUN AT RECORD LOWS AS HIGH
PRESSURE...CLEAR SKIES AND LIGHT WINDS WILL RESULT IN RADIATIONAL
COOLING. SINCE DEWPOINTS ARE IN THE SINGLE DIGITS AND 850 MB TEMPS
ARE BETWEEN -14 TO -10 WE COULD SEE TEMPS BOTTOM DOWN INTO THE LOW
TO UPPER TEENS AWAY FROM THE COAST. BELIEVE ALL SITES MINUS BOS HAVE
A GOOD SHOT.
WEDNESDAY NIGHT INTO THURSDAY NIGHT...MODERATE CONFIDENCE.
DYNAMIC LOW PRESSURE SYSTEM WILL DEEPEN AS IT APPROACHES THE REGION
FROM THE MIDWEST ON THURSDAY. USED A NON-DIURNAL TREND IN TEMPS ON
WED PM INTO THU AM AS WAA WILL BEGIN TO INCREASE AS WARM FRONT
PUSHES THROUGH. DEPENDING ON SURFACE TEMPS AND PRECIP TIMING THERE
IS A LOW PROB OF SOME FREEZING RAIN/DRIZZLE OR SLEET ACROSS THE
ROUTE 2 CORRIDOR OF MASS WEDNESDAY EVENING/NIGHT.
THE FIRST OF A SERIES OF FRONTAL WAVES ARRIVES BY THU. THE BULK OF
GUIDANCE SHOWS THE TROUGH BECOMES NEGATIVE TILT...ALLOWING FOR THE
INITIAL WAVE TO PASS OVER OR JUST INLAND OF SRN NEW ENGLAND WITH
THERMAL PROFILES SUPPORTING MAINLY RAIN THURSDAY INTO THURSDAY
NIGHT. STILL SOME TIMING DIFFERENCE ON WHERE AND WHEN THE HEAVIEST
PRECIP WILL MOVE THROUGH THE REGION. PWAT VALUES ARE CLOSE TO AN INCH
RESULTING IN 2 SD ABOVE NORMAL AND WITH STRONG LLJ OF 50-65 KTS
TAPPING INTO GULF MOISTURE...THE AREA COULD SEE A GOOD SLUG OF RAIN.
RIGHT NOW THING THAT MUCH OF THE AREA WILL SEE MODERATE RAINFALL
WITH POCKETS OF HEAVY RAINFALL LINGERING INTO THURSDAY NIGHT.
APPEARS THAT BOTH ENSEMBLE AND DETERMINISTIC GUIDANCE IS DEVELOPING
A SECONDARY LOW PRESSURE SYSTEM BY THURSDAY EVENING RIGHT OVER SNE.
THIS WILL ALLOW FOR PRECIP TO CONTINUE INTO THURSDAY NIGHT BEFORE
ENDING BY FRIDAY. AS DYNAMIC AS THIS SYSTEM IS IT IS VERY SLOW
MOVING THANKS TO THE SECONDARY LOW DEVELOPMENT. THIS WILL HELP
INCREASE RAINFALL TOTALS IN WHICH COULD BE OVER AN INCH IN SOME
LOCATIONS. THIS IS SUPPORTED BY ENSEMBLES GUIDANCE WHICH ARE SHOWING
HIGH PROBS OF OVER AN INCH OF QPF WITH EVEN A FEW PROBS OF CLOSE TO
2 INCHES. THIS MAY PUT A FEW AREA RIVERS ABOVE ACTION OR PERHAPS
FLOOD STAGE DEPENDING ON WHAT HAPPENS UPSTREAM. STAY TUNED THROUGHOUT
THE WEEK TO THE LATEST FORECAST.
COLD FRONT SWEEPING THROUGH FROM THE POTENT WEATHER SYSTEM LATE
THURSDAY NIGHT INTO FRIDAY MORNING. MAY NEED TO WATCH THE WINDS AS
GUSTY S-SW WINDS ON THU COULD COME CLOSE TO ADVISORY LVLS THU
AFTERNOON PRIOR TO THE FRONTAL WAVE.
THE ONE ADDED ISSUE IS THAT THESE WAVES WILL MOVE THROUGH DURING A
PERIOD OF ASTRONOMICALLY HIGH TIDES. AS THE PREVIOUS SHIFT
NOTED...THIS IS MOST LIKELY A SOUTH COASTAL POTENTIAL ISSUE GIVEN
THE CURRENT STORM TRACK. THERE IS STILL MORE TIME TO ASSESS...BUT
STAY TUNED TO UPDATES IN REGARD TO THE COASTAL FLOOD RISK FOR THE
LATE WEEK TIMEFRAME.
FRIDAY AND BEYOND...LOW CONFIDENCE.
DRY WEATHER TO START ON FRIDAY...UNLESS THE ABOVE MENTIONED SYSTEM
SLOWS DOWN. ANOTHER WAVE OF ENERGY WILL PUSH THROUGH THE FLOW ON
FRIDAY RESULTING IN THE DEVELOPMENT OF ANOTHER LOW PRESSURE SYSTEM
OFFSHORE. THIS SYSTEM APPEARS TO MOVE THROUGH LATE FRIDAY NIGHT INTO
SATURDAY WHERE TEMPS WILL BE COLD ENOUGH TO PERHAPS SUPPORT SNOW
SHOWERS. STILL A LOT OF UNCERTAINTY WITH THIS SYSTEM AS THE EXACT
STRENGTHEN...LOCATIONS AND TIMING OF THE LOW IS STILL IN QUESTION.
SOMETHING TO WATCH IN THE COMING DAY.
DEEP TROUGH WILL BEGIN TO LIFT BY SUNDAY WITH ANOTHER SHORTWAVE
MOVING THROUGH THE FLOW FOR EARLY NEXT WEEK. ONCE AGAIN HAVE A LOW
CONFIDENCE ON THE FEATURES OF THIS SYSTEM. BUT IT DOES APPEAR THAT AN
ACTIVE PATTERN WILL CONTINUE THIS WEEKEND INTO EARLY NEXT WEEK.
