The episode as NWS BOX wrote it up.
Low pressure moved up to southern New England from the southern plains bringing a mix of wintry precipitation to southern New England. This coincided with an arctic cold front moving through the region as well. Due to the heavy snow collected through the month of February, the roof of the Garden Center at Lowe's on Quaker Lane in Warwick collapsed.

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE TAUNTON MA
439 PM EST SAT FEB 21 2015
.SYNOPSIS...
LOW PRESSURE WILL MOVE ACROSS NEW ENGLAND TONIGHT BRINGING A MIX
OF WINTRY PRECIPITATION TO THE AREA INTO SUNDAY MORNING. AN ARCTIC
COLD FRONT MOVES ACROSS THE AREA SUNDAY NIGHT. NORTHWEST WINDS
WILL BRING BITTERLY COLD AIR FOR THE START OF THE WEEK. ANOTHER
ARCTIC COLD FRONT MOVES THROUGH ON WEDNESDAY WITH POTENTIAL FOR
SOME MORE SNOW. HIGH PRESSURE THEN FOLLOWS WITH ANOTHER PERIOD OF
BITTERLY COLD AIR.

.NEAR TERM /UNTIL 6 AM SUNDAY MORNING/...
430 PM UPDATE...
*** SNOW/SLEET AND FREEZING RAIN YIELDS DIFFICULT TRAVEL INTO THIS
EVENING ALONG THE COAST AND OVERNIGHT INLAND ***
SYNOPTIC OVERVIEW...
AT 4 PM THE LEADING EDGE OF THE SNOW SHIELD IS INTO RI AND EASTERN
MA. ONCE SNOW BEGINS IT QUICKLY BECOMES MODERATE WITH VSBY AOB 1
MILES ALONG WITH SNOWFALL RATES APPROACHING AN INCH PER HOUR. LATEST
WATER VAPOR IMAGERY SHOWS A NICE PLUME OF ENHANCED/COOLING CLOUD
TOPS FROM THE TN VLY NEWD INTO NEW ENGLAND. THIS IS IN RESPONSE TO
STRONG JET DYNAMICS IN THIS CONVEYOR BELT WITH 925 MB AND 850 MB
WIND SPEEDS +2 TO +3 STD FROM CLIMO...ALONG WITH STRENGTHENING UPPER
LEVEL JET STREAK AND RRQ OVER NEW ENGLAND. THESE STRONG JET DYNAMICS
ADVECT A PLUME OF PWATS EXCEEDING +1 STD DEVIATION FROM CLIMO. HENCE
PLENTY OF FORCING FOR ASCENT WITHIN A MOIST COLUMN. THIS YIELDS A
MODEL CONSENSUS QPF OF UP TO 1 INCH ALONG THE SOUTH COAST TAPERING
DOWN TO 0.40 INCHES ALONG THE MA/NH BORDER.
PTYPE AND SNOWFALL...
STRONG LOW LEVEL WARM ADVECTION ACROSS THE AREA IS BEING OFFSET OR
MODIFIED BY VERY COLD NEAR SHORE WATER TEMPS WITH MANY HARBORS/BAYS
PARTIALLY OR COMPLETELY FROZEN. AS A RESULT DEW PTS ARE ONLY IN THE
U20S ACROSS CAPE COD AND THE ISLANDS WITH TEENS WELL INLAND. GFS/NAM
AND HI RES GUID IN GOOD AGREEMENT THAT NOSE OF WARM AIR AROUND 925
MB HOLDS OFF UNTIL AFTER 03Z. THUS MOSTLY SNOW ACROSS THE REGION
THRU 03Z/10 PM...THEN BETWEEN 03Z AND 06Z WILL SEE LINE OF MIXED
PRECIP SPREAD NORTHWARD TO ABOUT A BDL-ORH-BED-BVY LINE AND HOLD
THERE OVERNIGHT...WITH ALL SNOW TO THE NW OF THIS LINE. THUS
EXPECTING ABOUT 4-6" OF SNOW ALONG AND NORTHWEST OF I-84 TO I-90 AND
NORTHEAST INTO I-495 CORRIDOR OR NORTHEAST MA. SOUTH OF THIS AREA
INTO NORTHEAST CT-MUCH OF RI INTO SOUTHEAST MA EXPECTING 2-4" OF
SNOW FOLLOWED BY A PERIOD OF SLEET/FREEZING RAIN 10 PM TO 1 AM. THIS
INCLUDES THE BOSTON TO PROVIDENCE CORRIDOR. CAPE COD AND THE ISLANDS
WILL HAVE A FEW HOURS THIS EVENING OF SNOW...SLEET AND POSSIBLY
FREEZING RAIN BEFORE CHANGING OVER TO ALL RAIN. GIVEN THIS HAVE
EXPANDED THE WINTER WEATHER ADVISORY FOR CAPE COD AND THE ISLANDS.
AS PREVIOUS FORECASTER INDICATED DESPITE SURFACE TEMPS CLIMBING INTO
THE MU30S A FROZEN GROUND MAY STILL YIELD FREEZING RAIN. HENCE VERY
TREACHEROUS TRAVEL INTO AT LEAST THIS EVENING AND OVERNIGHT ACROSS
THE INTERIOR.
MAY SEE LOWER SNOW TOTALS ALONG THE MA/NH BORDER AS BEST FORCING FOR
ASCENT IS FARTHER SOUTH CLOSER TO THE I-84 CORRIDOR NORTHEAST INTO I-
90 AND I-495 OF NORTHEAST MA. LITTLE CONCERNED HOW SNOW INTENSITY
DROPS OFF ACROSS NORTHERN NJ/LOWER HUDSON VALLEY WESTWARD INTO PA.
COULD BE SOME MID LEVEL DRY AIR THAT SHOULD EVENTUALLY RESATURATE.
THUS RADAR SHOULD FILL BACK IN TOWARD 00Z/7 PM.
RAINFALL...
AS PTYPE TRANSITIONS FROM SNOW/SLEET TO FREEZING RAIN IN THE 10 PM
TO 1 AM WINDOW...EXPECT A PERIOD OF MODERATE TO PERHAPS HEAVY RAIN
ALONG THE SOUTH COAST. MODELS SUGGEST UP TO 0.50 INCHES OF RAINFALL
AFTER THE CHANGEOVER. THIS COMBINED WITH SNOW CLOGGED STORM DRAINS
WILL RESULT IN AT LEAST MINOR TO PERHAPS MODERATE STREET/URBAN TYPE
FLOODING. IN ADDITION...THIS RAINFALL COMBINED WITH LEFTOVER
SNOWPACK AND TODAY/S SNOWFALL WILL INCREASE THE RISK OF ROOF
COLLAPSES. GREATEST RISK LIKELY ALONG THE SOUTH COAST WHERE RAINFALL
WILL BE HEAVIEST.
WINDS...
NOW THAT LOW LEVEL WARM ADVECTION IS INCREASING INVERSION IS
BEGINNING TO DEVELOP. SO DESPITE LOW LEVEL JET INCREASING TO 50-60
KTS STRONGER WINDS ALOFT WILL NOT BE ABLE TO MIX DOWN AS WAS THE
CASE THIS AFTERNOON.
&&
.SHORT TERM /SUNDAY/...
PRECIP LINGERS IN THE MORNING. PTYPE REMAINS TRICKY BUT SHOULD SEE
SNOW/SLEET ALONG AND NW OF I-84/I-90 AND I-495 WITH RAIN ELSEWHERE.
HOWEVER GIVEN COLD GROUND WOULD NOT BE SURPRISED TO SEE POCKETS OF
FREEZING RAIN IN NORTHEAST CT/NORTHWEST RI INTO NORTHEAST MA
INCLUDING THE BOSTON TO PROVIDENCE CORRIDOR. ALL RAIN LIKELY FOR
SOUTHEAST MA INCLUDING CAPE COD AND THE ISLANDS WHERE TEMPS MAKE A
RUN AT 40.
TROUGH MOVES OFFSHORE WITH A DRYING TREND FROM NW TO SE AS THE
MORNING PROGRESSES. BY MIDDAY PRECIP WILL HAVE ENDED MOST LOCATIONS
EXPECT LINGERING OVER CAPE COD AND THE ISLANDS INTO EARLY AFTERNOON.
DESPITE COLUMN DRYING OUT LOW CLOUDS SHOULD HANG TOUGH ALONG WITH
POSSIBLE AREAS OF DRIZZLE.
&&
.LONG TERM /SUNDAY NIGHT THROUGH SATURDAY/...
BIG PICTURE...
MEAN PATTERN FOR NEXT WEEK CONTINUES TO FEATURE A TROUGH IN THE EAST
AND RIDGE IN THE WEST. SOME SIGNS OF THE WESTERN RIDGE SHIFTING
FARTHER WEST OVER THE PACIFIC LATE IN THE WEEK. SHORTWAVES TRAVEL
THROUGH THE EASTERN TROUGH DURING THE WEEK. ONE PASSES NORTH OF NEW
ENGLAND MONDAY. A SECOND SHORTWAVE DIVES SOUTH FROM THE ARCTIC AND
SWEEPS ACROSS NEW ENGLAND AROUND WEDNESDAY. CONTOUR HEIGHTS REMAIN
BELOW NORMAL AND OCCASIONALLY WELL BELOW NORMAL MOST OF THE WEEK.
THIS POINTS TO CONTINUED COLD WEATHER THROUGH THE WEEK WITH ONE
PERIOD OF UNSETTLED WEATHER MIDWEEK. MODEL MASS FIELDS ARE SIMILAR
THROUGH FRIDAY ALTHOUGH WITH SOME DIVERGENCE LATE IN THE PERIOD. WE
USED A BLEND OF THE LONG RANGE GUIDANCE.
DAILIES...
SUNDAY NIGHT-MONDAY... ARCTIC COLD FRONT MOVES OFFSHORE SUNDAY
NIGHT. DIFFERENCES IN TIMING BETWEEN GFS AND ECMWF WITH THE GFS A
LITTLE FASTER. BUT TREND AND RESULT IS THE SAME. NORTHWEST WINDS
TRAILING THE FRONT THEN DRAWS ARCTIC COLD AIR OVER THE REGION. THIS
ARCTIC FLOW CONTINUES ON MONDAY. HIGH PRESSURE BUILDS OVER THE
REGION MONDAY NIGHT DIMINISHING WINDS AND PROVIDING MOSTLY CLEAR
SKIES.
OBSERVED TEMPERATURES UPSTREAM SUGGEST SUNDAY NIGHT MIN SFC TEMPS
HERE WILL BE IN THE ZERO TO 15F RANGE. WE USED 5 TO 15 ABOVE. TEMPS
ALOFT ON MONDAY START THE DAY SUPPORTING MAX SFC TEMPS OF 15 TO
20F...BUT THEN COOLING ALOFT REDUCES THIS TO 10 TO 15F IN THE
AFTERNOON. SO LIKELY SCENARIO HAS TEMPS GOING UP A LITTLE IN THE
MORNING BUT THEN FALLING AGAIN BY AFTERNOON. CLEAR SKIES AND
DIMINISHING WIND MONDAY NIGHT WILL ALLOW RADIATIONAL COOLING WITH
DEWPOINTS BELOW ZERO AND SOME BELOW -10. WE NUDGED MIN TEMPS 2-3F
COLDER THAN GUIDANCE.
COLD ADVECTION MIXING WILL REACH TO 900 OR 925 MB. WINDS IN THIS
MIXED LAYER REACH 25 KNOTS ON THE ECMWF AND 30 KNOTS ON THE GFS.
EXPECT NORTHWEST WIND GUSTS REACHING THIS RANGE ON MONDAY THEN
DIMINISHING MONDAY NIGHT.
WIND CHILLS MONDAY WILL BE ON EITHER SIDE OF ZERO. THEN AS THE WIND
DIMINISHES MONDAY NIGHT THE CHILL CAUSED BY THE REMAINING WIND WILL
REACH 10 TO 20 BELOW ZERO. A WIND CHILL ADVISORY MAY BE NEEDED
ESPECIALLY IN WESTERN/CENTRAL MASSACHUSETTS.
FINALLY...THE FLOW OF VERY COLD AIR OVER THE COASTAL WATERS WILL
RESULT IN ANOTHER ROUND OF OCEAN EFFECT SNOW SHOWERS. AIR-WATER
TEMPERATURE DIFFERENTIALS WILL REACH 20-23C. THE NORTHWEST FETCH
SHOULD FAVOR BANDS THAT EITHER GRAZE OR STAY NORTH/EAST OF OUTER
CAPE COD.
TUESDAY-WEDNESDAY... HIGH PRESSURE SHIFTS EAST OF NEW ENGLAND
TUESDAY WITH A SOUTH/SOUTHWEST FLOW DEVELOPING. THIS WILL BRING
INCREASING SKY COVER LATER TUESDAY THROUGH WEDNESDAY. SURFACE
CLIPPER PASSES NORTH OF NEW ENGLAND WEDNESDAY BUT SWINGS A COLD
FRONT THROUGH THE REGION IN THE EVENING. NORTHERN AND SOUTHERN JETS
MOVE CLOSE TO EACH OTHER OVER NEW ENGLAND AND THE MID ATLANTIC
COASTS AND COULD SPIN UP A WAVE ALONG THE FRONT AS IT REACHES THE
COAST. THE 00Z GEM GLOBAL IS THE ONLY ONE TO SUGGEST THIS SCENARIO
WHILE THE GFS AND ECMWF MAINTAIN A SIMPLE COLD FROPA. THE FLOW AND
THE MOISTURE PROFILES ARE MEDIOCRE. BUT THE PROXIMITY OF THE TWO
JETS IS A RED FLAG THAT IS DIFFICULT TO IGNORE. WE WILL MAINTAIN
CHANCE POPS FOR SNOW SHOWERS TUESDAY NIGHT AND WEDNESDAY MORNING.
THIS REMAINS LOW CONFIDENCE.
THURSDAY-FRIDAY... HIGH PRESSURE FROM THE NORTHERN PLAINS BUILDS
OVER THE NORTHEAST USA. THIS WILL MEAN DRY WEATHER. IT ALSO MEANS
ANOTHER NORTHWEST FLOW OF ARCTIC AIR DRAWN SOUTH BY THE DEPARTING
SYSTEM. THE COLD AIR SHOULD BRING OCEAN EFFECT SNOW NEAR CAPE COD
WITH AIR-WATER TEMP DIFFERENCES AROUND 17C. A NORTH FLOW WOULD BRING
THE SHOWER BANDS INTO CAPE COD BAY WHILE NORTHWEST FLOW WOULD AGAIN
KEEP THE BANDS JUST EAST OF PROVINCETOWN. TEMPS ALOFT OVER LAND
WOULD BE AROUND -20 TO -25C WHICH WOULD SUPPORT MAX SFC TEMPS 15 TO
25F.
