The episode as NWS BOX wrote it up.
An intensifying clipper low pressure system passed north of southern New England, bringing an arctic cold front through the area. This resulted in snow across much of the region and strong, damaging winds near the coast. Unseasonably cold weather then spread across southern New England.
The local office's own words before the first event, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.
NWS Boston/Norton, MA wrote its last area forecast discussion before the first event at Apr 3, 12:31 AM EST, 29 minutes earlier.
AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE TAUNTON MA
131 AM EDT SUN APR 3 2016
.SYNOPSIS...
RAIN AFTER MIDNIGHT TRANSITIONING TOWARDS A BRIEF PERIOD OF HEAVY
SNOW IN MOST LOCALES BY DAYBREAK SUNDAY. DEVELOPING STRONG WINDS
MAY RESULT IN WHITEOUT CONDITIONS ALONG WITH DANGEROUS TRAVEL FOR
A SHORT TIME SUNDAY MORNING. THE SNOW WILL COME TO AN END BY LATE
SUNDAY MORNING...BUT IT WILL REMAIN VERY WINDY. ANOTHER LOW PRESSURE
TRACKS OVER OR NEAR THE SOUTH COAST OF NEW ENGLAND MONDAY...BRINGING
THE RISK FOR ANOTHER ROUND OF ACCUMULATING SNOW TO THE AREA. DRYING
TREND TUE BUT REMAINING UNSEASONABLY COLD. MODERATING TEMPERATURES
MID TO LATE NEXT WEEK BUT ALSO THE RISK OF WET WEATHER.
&&
.NEAR TERM /MESOANALYSIS/...
1 AM UPDATE...
WILL USE THIS DISCUSSION AS A MESOSCALE ANALYSIS DURING THE OVERNIGHT
PERIOD AND TREAT THE SHORT-TERM DISCUSSION AS AN OVERVIEW NARRATIVE
TO THE STORM SYSTEM GOING INTO SUNDAY.
STORM CENTER EMERGING OVER THE NYC METRO DOWN TO 992 COINCIDENT
WITH STRONGER PRESSURE FALLS OF 1 MB / HR TO START. CONTINUED
PREFERENCE TO A CONSENSUS OF NEAR-TERM HIGH-RES GUIDANCE...NAMELY
THE HRRR. SEVERAL THINGS WORTH NOTING.
1) CONVECTIVE ACTIVITY OVER THE NYC METRO AND NJ COAST WILL SWEEP
E/NE ACROSS S/SE COASTAL NEW ENGLAND INTO THE EARLY MORNING HOURS
EXPECTED TO CONTINUE E/NE ALONG THE S COAST. CHANCE THUNDER IN THE
FORECAST ACCORDINGLY. MINIMAL INSTABILITY AVAILABLE BUT WITH THE
DEEP CYCLOGENESIS AND INTENSE LIFT ONGOING WITHIN THE REGIME OF
THE COLD FRONT AND BENT BACK WARM FRONT TO THE LOW OVER THE NYC
METRO AREA...SHOULD BE NO STOPPING ADDITIONAL THUNDERSTORM ACTIVITY
AS THE STORM PEELS OFF TO THE E. SHORT-FUSED STATEMENTS LIKELY
NEEDED FOR S/SE TIER OF NEW ENGLAND CLOSE TO THE COAST BUT SUB
WARNING.
2) SNOW BAND EMERGING
DEVELOPING ACROSS THE HUDSON RIVER VALLEY AS ENERGY CONGEALS ROUND
THE DEEPENING LOW CENTER. ALREADY SEEING SOME LIGHTNING IN NE PA.
TOWARDS EARLY MORNING...SHOULD SEE ROUGHLY SW TO NE BANDING MAINLY
COINDICENT WITH SURFACE TO LOW LEVEL WARM FRONTAL INFLOW BENEATH
THE MID LEVEL VORTEX AND POSITIVE DIFFERENTIAL VORTICITY ADVECTION
INTENSIFY IN TANDEM WITH DEEPENING CYCLOGENSIS OF THE STORM ACROSS
S NEW ENGLAND. DEEP FRONTOGENETICAL FORCING.
ANTICIPATING A 1 TO 2 HOUR BURST OF HEAVY SNOW / THUNDERSNOW THAT
WILL RESULT IN QUICK ACCUMULATIONS AND NEAR WHITE OUT CONDITIONS
IF NOT SO. VISIBILITIES OF A QUARTER MILE OR LESS POSSIBLE. WILL
MAKE FOR HAZARDOUS TRAVEL CONDITIONS EARLY THIS MORNING.
3) WINDS...
CONTINUED REPORTS OF 40 TO 50 MPH NW GUSTS UPSTREAM. AS THE STORM
CONTINUES TO DEEPEN PARENT WITH RAPID PRESSURE FALLS...EXPECTING
WINDS TO RESPOND ESPECIALLY IN WAKE OF THE STORM DURING THE MORNING
PERIOD AS IT SWEEPS E OF THE S COAST OF NEW ENGLAND.
ALREADY SOME GUSTS IN THE NYC METRO OF 40 MPH. ANTICIPATING BLUSTERY
WINDS TO BEGIN MOVING INTO THE HUDSON VALLEY REGION IN THE NEXT
HOUR OR TWO AS LAPSE RATES BEGIN TO STEEPEN WITH THE USHERANCE OF
COLD AIR E. YOU CAN SEE THIS AREA WITHIN THE SPC MESOANALYSIS.
&&
.SHORT TERM /THROUGH TONIGHT/...
*/ HIGHLIGHTS FOR EARLY SUNDAY MORNING TOWARDS EVENING...
- HIGH IMPACT/SHORT DURATION WINTER WEATHER EVENT
- BRIEF PERIOD OF HEAVY SNOW WITH WHITEOUT CONDITIONS POSSIBLE
- STRONG-DAMAGING WIND GUSTS OF 50 TO 60 MPH WITH UP TO 65 MPH
POSSIBLE ACROSS SOUTH COAST/CAPE/ISLANDS
*/ DISCUSSION...
FOLLOWING CLOSELY WITH A CONSENSUS OF HIGH-RES GUIDANCE NAMELY THE
HRRR.
SHORT DURATION HIGH IMPACT WINTER WEATHER EVENT EARLY SUNDAY MORNING
TOWARDS EVENING. POTENT ARCTIC SHORTWAVE WILL APPROACH FROM THE WEST
INDUCING RAPID CYCLOGENESIS SOMEWHERE NEAR AND ALONG THE S COAST.
DEVELOPING AFTER MIDNIGHT...INITIAL RAIN LOOKS TO CHANGE TO SNOW IN
MOST LOCATIONS FROM NW TO SE BETWEEN 3 AND 7 AM. WHILE SNOW WILL NOT
LAST LONG IN A GIVEN LOCATION...A 1 TO 3 HOUR PERIOD OF HEAVY SNOW
IS EXPECTED WITH NEAR WHITE OUT CONDITIONS AS THE LOW BOMBS OUT.
FORTUNATELY...THE STORM IS VERY PROGRESSIVE AND THE SNOW THREAT
SHOULD BE OVER BY LATE MORNING AND GIVE WAY TO PARTIAL SUNSHINE BY
AFTERNOON.
1) HIGH IMPACT SNOW POTENTIAL...
AS THE LOW RAPIDLY BOMBS OUT AND MID LEVELS CLOSE OFF...A SHORT
DURATION / HIGH IMPACT SNOW EVENT IS EXPECTED. A VERY STRONG MID
LEVEL BANDING SIGNATURE WILL SETUP...COUPLED WITH STEEP MID LEVEL
LAPSE RATES EXCEEDING 8C/KM...SHOWALTER INDICES NEAR ZERO AND 30
TO 40 MICROBARS PER SECOND OF LIFT IN THE SNOW-GROWTH REGION. THE
RESULT WILL BE RAIN FLIPPING OVER TO A 1 TO 3 HOUR PERIOD OF HEAVY
SNOW...AT LEAST AWAY FROM THE SOUTH COAST/CAPE AND ISLANDS. WHILE
THE SNOW WILL NOT LAST LONG...THE RARE PARAMETERS MENTIONED ABOVE
MAY RESULT IN LOCALIZED 2"+ PER HOUR SNOWFALL RATES. DECENT SHOT
OF ISOLATED THUNDER-SNOW GIVEN RARE INSTABILITY...SO HAVE CONTINUED
IN THE FORECAST. IN ADDITION...STRONG TO DAMAGING WIND GUSTS ARE
EXPECTED WHICH WILL DISCUSS FURTHER BELOW.
SNOW ACCUMULATIONS: QUITE TRICKY SINCE THIS WILL BE A VERY DYNAMICAL
SYSTEM WITH SIGNIFICANT BANDING POTENTIAL. EXPECTING A GENERAL 1 TO
4 INCHES OF SNOW AWAY FROM THE IMMEDIATE SOUTH COAST/CAPE/ISLANDS.
THERE IS A LOW RISK FOR LOCALIZED 5 TO 6 INCH SNOW AMOUNTS ACROSS
THE HIGHER TERRAIN. DESPITE THE WARM GROUND...WHERE THE SNOW FALLS
HEAVY IT WILL ACCUMULATE ON ROADWAYS EVEN IN THE LOWER ELEVATIONS.
2) STRONG-DAMAGING WINDS EXPECTED...
THE LOW BOMBING OUT AND THEN RAPIDLY PULLING AWAY WILL RESULT IN
STRONG TO DAMAGING WIND GUSTS. IMPRESSIVE PRESSURE RISES OF 10 TO
15 MB IN JUST 3 HOURS WILL HELP IN TRANSPORTING VERY STRONG WINDS
TO THE GROUND WITH THE ASSISTANCE OF COLD AIR ALOFT AND STEEP
LAPSE RATES PREVIOUSLY MENTIONED OF 8C/KM.
STRONGEST OF THE WINDS EXPECTED EARLY SUNDAY MORNING WITH NW WIND
GUSTS OF 50 TO 60 MPH...WITH PERHAPS NEAR 65 MPH ALONG THE SOUTH
COAST/CAPE/ISLANDS. WHILE THE STRONGEST WINDS WILL OCCUR DURING
THE MORNING...EXCELLENT MIXING WITH VERY COLD AIR/ALOFT AND STEEP
LOW LEVEL LAPSE RATES WILL ALLOW 40 TO 55 MPH WIND GUSTS TO CONTINUE
TOWARDS EVENING.
AFTER COORDINATING WITH OUR ADJACENT OFFICES...HAVE ISSUED A HIGH
WIND WARNING FOR ALL OF S NEW ENGLAND. WHILE THE STRONGEST WINDS
WILL LIKELY BE ACROSS OUR S/SE ZONES...STILL A GOOD POTENTIAL FOR
DAMAGING WIND GUSTS ACROSS THE ENTIRE REGION.
3) SUMMARIZING HIGH IMPACT / SHORT DURATION EVENT...
THIS WILL BE A HIGH IMPACT / SHORT DURATION EVENT CONSIDERING THE
HEAVY SNOW AND POSSIBLE WHITE-OUT CONDITIONS ONLY LASTING BETWEEN
1 AND 3 HOURS...ALONG WITH STRONG TO DAMAGING WINDS.
IT IS DURING THIS BRIEF TIMEFRAME EARLY SUNDAY MORNING CONCLUDING
TOWARDS MIDDAY THAT TRAVEL WILL BE DANGEROUS. WHERE THE SNOW FALLS
HEAVILY...IT WILL ACCUMULATE ON THE ROADS. MOTORISTS TRAVELING
BETWEEN 4 AND 10 AM ON SUNDAY MORNING SHOULD BE PREPARED FOR BRIEF
HEAVY SNOW AND NEAR ZERO VISIBILITY.
HIGH TEMPS SUN AFTERNOON WILL ONLY RECOVER INTO THE 30S TO NEAR 40
DESPITE PARTIAL SUNSHINE.
&&
.LONG TERM /MONDAY THROUGH SATURDAY/...
HIGHLIGHTS...
* VERY ACTIVE WEATHER PATTERN NEXT 7 DAYS
* TEMPERATURES - UNSEASONABLY COLD FOR EARLY APRIL SUNDAY THROUGH
WEDNESDAY...THEN MODERATING LATE NEXT WEEK
* PRECIPITATION - ACCUMULATING SNOW LIKELY MONDAY ALONG WITH OCEAN
EFFECT SNOW SHOWERS EASTERN MA TUE MORNING. OTHERWISE DRY TUE INTO
WED FOLLOWED BY WET WEATHER LATE NEXT WEEK
OVERVIEW AND MODEL PREFERENCES...
HIGHLY AMPLIFIED FLOW PATTERN IS THE MAIN ISSUE AT HAND FOR THE
COMING WEEK. THIS IS WITHIN A VERY NEGATIVE EPO...AND POSITIVE PNA
REGIME...WHICH ALLOWS A SUSTAINED LONGWAVE TROF TO DOMINATE
ACROSS THE ERN CONUS. THE IMPLIED CYCLONIC CURVATURE AND
CONSISTENT DRAW FROM THE ARCTIC SUGGESTS THE GENERALLY COOL AND
ACTIVE WX PATTERN EXPECTED TO BEGIN TOMORROW SUSTAINS ITSELF AT
LEAST UNTIL THE END OF THE WEEK.
ALTHOUGH SOME SMALL /MAINLY MESO-SCALE/ DISCREPANCIES CONTINUE TO
CROP UP...MAINLY WITH THE CLIPPER SYSTEM MON AND THE LATE WEEK
SLOW MOVING FRONT...THERE IS ENOUGH AGREEMENT BETWEEN ENSEMBLES
ESPECIALLY THAT AN OVERALL CONSENSUS BLEND OF GEFS/ECENS SHOULD
STILL PROVIDE A GOOD FOUNDATIONAL FORECAST.
DETAILS...
SUN NIGHT...
BRIEF RIDGING WITHIN COLD ADVECTION REGIME WILL ALLOW FOR A
MAINLY DRY OVERNIGHT PERIOD UNTIL WEAK MID LVL FRONTOGENESIS
APPROACHES FROM THE W ATTENDANT TO CLIPPER LOW. ALTHOUGH ONLY
MODEST BREAKS IN SKYCOVER AND BRIEF WEAK FLOW ARE EXPECTED...TEMPS
MAY STILL BOTTOM OUT IN THE 20S AND UPPER TEENS IN SPITE OF
LACKING RADIATIONAL COOLING SETUP.
EARLY MON INTO MON NIGHT...
LATE SEASON MODEST SNOWFALL EVENT LOOKING MORE LIKELY. WEAK
CLIPPER WITH NEAR NORMAL PWATS WILL APPROACH FROM THE W AND DIVE
JUST S OF THE REGION THANKS TO WEAK STALLED FRONTAL BOUNDARY
OFFSHORE. MODEST WARM CONVEYOR/NRN QUADS F-GEN TO WORK WITH...SO
SUSPECT PRECIP ACROSS MOST OF SRN NEW ENGLAND WITH SOME AREAS NEAR
AND S OF THE MASS PIKE ESPECIALLY SEEING AS MUCH AS 0.5 INCHES OF
LIQUID.
H92 TEMPS WILL APPROACH 0C NEAR THE S COAST...DROPPING ABOUT -6C
AT THE MASS/NH BORDER. THEREFORE...EXCEPT FOR SOME MODEST
MIXING...MUCH OF THIS IS EXPECTED TO FALL AS SNOW...ESPECIALLY IF
ANY DYNAMIC COOLING IS OBSERVED. DRY DRAINAGE FLOW FROM THE
N...WILL LIKELY YIELD A FAIRLY TIGHT GRADIENT TO THE N. REGARDING
SNOWFALL AMOUNTS...BULK OF THE LIFT IS BELOW THE SNOW GROWTH
REGION...BUT ENOUGH IS WITHIN TO WARRANT DECENT DENDRITE
DEVELOPMENT. PAVED SURFACES MAY STILL REMAIN TOO WARM FOR MUCH
ACCUMULATION SO GRASSY SFCS WILL BE THE MOST LIKELY TO SEE ANY
ACCUM. ENOUGH FOR HEADLINES...POSSIBLY IN A REGION ACROSS SRN MA
AND ACROSS NRN RI AND CT.
MON NIGHT INTO TUE...
PRES GRADIENT ORIENTATION BECOMES NEARLY W-E AS HIGH PRES MOVES
INTO THE GREAT LAKES AND LOW PRES STRENGTHENS S OF THE MARITIMES.
THIS SUGGESTS A PROPER FLOW FOR OCEAN EFFECT SNOWS OUT OF THE NNW.
H85 TEMPS AVERAGE NEAR -16C WITH SST/S NEAR +6C. THIS SUGGESTS A
DELTA-T VALUE NEAR 22C. THEREFORE...AREAS OF THE CAPE/PLYMOUTH
COUNTY MA WILL HAVE TO WATCH FOR MODERATE SHSN CONTINUING UNTIL
THE PRES GRADIENT INCREASES AND SHIFTS THE FLOW MORE W-E DURING
THE DAY ON TUE. THE COLD H85/H92 TEMPS ALSO SUGGEST HIGHS STRUGGLE
ONLY IN THE 30S.
TUE NIGHT INTO WED...
LIKELY THE QUIETEST STRETCH. HIGH PRES NEARLY 1035MB CRESTS OVER
THE REGION. WITH H92 TEMPS REMAINING NEARLY -2C TO -5C...TEMPS
WILL REMAIN GENERALLY BELOW NORMAL THROUGH THE PERIOD. WITH HIGHS
ONLY REACHING THE LOW 40S AND LOWS STILL BELOW FREEZING.
THU AND FRI...
TEMPERATURES BEGIN TO WARM FINALLY BY THE LATTER HALF OF THE
WEEK...AS RETURN FLOW DEVELOPS ALLOWING H92 TEMPS BACK TO NEAR +4C
TO +6C. HOWEVER...PWATS ALSO REACH NEARLY 2 STD DEVIATIONS ABOVE
NORMAL AS A SLOW MOVING FRONT APPROACHES AND SLOWLY CROSSES THE
REGION BY FRI. THEREFORE...EXPECT A TRANSITION TO MORE WIDESPREAD
RAIN SHOWERS LATE THU INTO EARLY FRI. THERE IS A STRONG SHORTWAVE
TO WATCH WHICH COULD LEAD TO SECONDARY FRONTAL WAVE DEVELOPMENT
LATE FRI. ECMWF CONTINUES TO BE THE STRONGEST MODEL WITH THIS...AS
IT BRINGS ANOTHER ROUND OF POTENTIALLY HEAVY RAINFALL. FOR
NOW...WILL CONTINUE WITH THE ENSEMBLES WHICH ARE NOT QUITE AS
ROBUST...HOWEVER THIS WILL BE SOMETHING TO WATCH BOTH FOR THE
HEAVY RAIN POTENTIAL...AND THE RISK FOR SOME COASTAL FLOODING
ISSUES THANKS TO VERY HIGH ASTRO-TIDES DURING THIS PERIOD...TOPING
OUT ABOVE 12 FT IN BOSTON HARBOR.
NEXT WEEKEND...
STILL TOO UNCERTAIN TO NAIL DOWN ANY TIMING...BUT SLOW MOVING
UPPER LVL CUTOFF IS LIKELY TO YIELD UNSETTLED CONDITIONS WITH
DIRUNALLY DRIVEN SHOWERS POSSIBLE.
