A potent Alberta Clipper low moved from southwestern Canada on January 24th to the Plains states and Ohio Valley on the 25th. The low then redeveloped off the Mid Atlantic coast on the 26th and rapidly intensified into a strong nor'easter, bringing heavy snow and strong winds to Southern Connecticut, with blizzard conditions in New London County.

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE NEW YORK NY
636 AM EST MON JAN 26 2015
.SYNOPSIS...
A NOR'EASTER DEVELOPS OFF THE DELMARVA COAST THIS AFTERNOON AND
TRACKS SLOWLY NORTH TONIGHT AS IT INTENSIFIES REACHING JUST EAST OF
MONTAUK POINT BY TUESDAY NIGHT. THE STORM WEAKENS AS IT MOVES EAST
TO THE GULF OF MAINE ON WEDNESDAY. HIGH PRESSURE ON THURSDAY IS
FOLLOWED BY A CLIPPER LOW PASSING ACROSS THURSDAY NIGHT INTO EARLY
FRIDAY. COLD HIGH PRESSURE BUILDS IN FOR THE WEEKEND.
&&
.NEAR TERM /UNTIL 6 PM THIS EVENING/...
FORECAST ON TRACK THIS MORNING. LIGHT SNOW/FLURRIES BEING REPORTED
ACROSS PARTS OF NE NJ AND NYC METRO. LIGHT SNOW WILL EXPAND IN
COVERAGE FROM SOUTH TO NORTH THROUGH THE MORNING HOURS. DEW POINTS
IN THE SINGLE DIGITS ACROSS SOUTHERN CT WILL LIKELY PREVENT MUCH
SNOW FROM FALLING HERE UNTIL MID/LATE AFTERNOON WITH BETTER LIFT.
SURFACE LOW PRESSURE IS CURRENTLY LOCATED OVER THE SOUTHERN
APPALACHIANS...AND WILL MOVE OFF THE COAST THIS MORNING AND
DEVELOP INTO A NOR'EASTER.
LIGHT SNOW IS EXPECTED TO DEVELOP THIS MORNING ACROSS AT LEAST SW
PORTIONS OF THE TRI-STATE. THIS SNOW WILL SLOWLY EXPAND NORTHWARD
THROUGHOUT THE DAY. NOT EXPECTING MORE THAN 1 TO 3 INCHES WITH
THIS FIRST WAVE OF SNOW.
TEMPERATURES WILL ONLY BE IN THE LOWER AND MIDDLE 20S INLAND...TO
THE UPPER 20S AND LOWER 30S CLOSER TO THE COAST.
&&
.SHORT TERM /6 PM THIS EVENING THROUGH 6 PM TUESDAY/...
A LIFE THREATENING...POTENTIALLY HISTORIC WINTER STORM EXPECTED
FROM LATE TODAY INTO TUESDAY...
NWP GUIDANCE HAS SHOWN A LITTLE MORE SPREAD THAN ONE WOULD LIKE TO
SEE AT SUCH A SHORT RANGE. MUCH OF THE 00Z GUIDANCE LOWERED QPF
AMOUNTS FOR MUCH OF THE REGION...WHICH WOULD MEAN LOWER SNOW
TOTALS. HOWEVER...THE 00Z ECMWF REMAINED VERY CONSISTENT WITH ITS
PREVIOUS RUNS. IT DID LOWER QPF SLIGHTLY...BUT THE OVERALL EVOLUTION
OF THE SYSTEM REMAINED SIMILAR TO ITS 12Z RUN. DID NOT WANT TO MAKE
DRASTIC CHANGES TO THE EXPECTED SNOW AMOUNTS AND HEADLINES WITH
JUST ONE MODEL CYCLE. IN FACT...THE LATEST 06Z NAM HAS COME INTO
CLOSER AGREEMENT WITH THE 00Z ECMWF. THE 21Z AND 03Z SREF MEANS
REMAINED SIMILAR TO THE 00Z ECMWF AND 06Z NAM.
THE 00Z GFS APPEARS TO BE A FAST NE OUTLIER. IT MAY ALSO BE
SUFFERING FROM CONVECTIVE FEEDBACK AS THE SURFACE LOW FOLLOWS QPF
MAXIMUM OFFSHORE...AND DOES NOT SEEM TO GET FULLY CAPTURED BY THE
UPPER LOW.
STILL ANTICIPATE THE LOW TO UNDERGO RAPID INTENSIFICATION AS THE
PARENT UPPER LOW CUTS OFF ALOFT NEAR THE MID ATLANTIC COAST
TONIGHT. THE LOW STALLS SE OF MONTAUK LATE TONIGHT INTO TUESDAY. A
PROLONGED PERIOD OF MODERATE TO HEAVY SNOW IS EXPECTED ON THE NW
FLANK OF THE LOW...IN THE DEFORMATION ZONE. THE MID LEVEL LOW
CENTERS AND INTENSE MID LEVEL FRONTOGENESIS WILL PROMOTE HEAVY
SNOW BANDS...BUT IT IS IMPOSSIBLE TO PREDICT THEIR LOCATION THIS
FAR OUT. MODELS ALSO HAVE A TENDENCY TO NOT SPREAD THE BEST LIFT
FAR ENOUGH NW IN INTENSE CYCLONES.
WITH ALL OF THIS IN MIND...DID LOWER SNOW TOTALS SLIGHTLY IN
COLLABORATION WITH SURROUNDING OFFICES AND WPC...BUT WE ARE STILL
EXPECTING AN OVERALL 18 TO 24 INCHES...LOCALLY HIGHER WHERE BEST
MESOSCALE SNOW BANDING SETS UP. SNOWFALL RATES OF 2-4 INCHES PER
HOUR EXPECTED LATE TONIGHT INTO TUE MORNING.
IN ADDITION...THE DEEP LOW PRESSURE COMBINED WITH STRONG HIGH
PRESSURE TO THE NORTH AND WEST AND HEAVY FALLING/BLOWING SNOW WILL
CREATE BLIZZARD CONDITIONS ACROSS THE ENTIRE REGION. A BLIZZARD
WARNING REMAINS IN EFFECT...WITH POTENTIAL FOR SUSTAINED WINDS UP
TO 35 MPH ON LONG ISLAND...AND WIND GUSTS RANGING FROM 40 MPH
INLAND...TO 45-50 MPH MOST ELSEWHERE. GUSTS UP TO 60 MPH CANNOT BE
RULED OUT ACROSS FAR EASTERN LONG ISLAND.
WITH THE LOW NEARLY STALLING NEAR CAPE COD ON TUESDAY...LIGHT TO
OCCASIONALLY MODERATE SNOW IS POSSIBLE IN MESOSCALE
BANDS...ESPECIALLY LATE TUESDAY MORNING INTO EARLY AFTERNOON.
TEMPS DURING THE STORM WILL GENERALLY BE IN THE 20S...EXCEPT
FALLING TO 15-20 TONIGHT INLAND. WIND CHILLS WILL BE MOSTLY IN
THE SINGLE DIGITS TO MID TEENS...BUT COULD GET CLOSE TO ZERO ACROSS
SOUTHERN CT. TEMPERATURES ON TUESDAY WILL ONLY BE IN THE LOWER TO
MIDDLE 20S.
&&
.LONG TERM /TUESDAY NIGHT THROUGH SUNDAY/...
THE NOR'EASTER BEGINS TO FILL AND PULL AWAY TUESDAY NIGHT. LIGHT
SNOW ENDS FROM WEST TO EAST WITH AN INCH OR LESS OF ADDITIONAL
ACCUMULATION. WINDS ALSO DIMINISHING AND HAVE REMOVED MENTION OF
BLOWING SNOW.
BECOMING SUNNY ON WEDNESDAY WITH 15-20 MPH WINDS. TEMPS FCST BELOW
MOS WITH SNOW COVER. WIND CHILLS ON WEDNESDAY ARE IN THE LOWER
TEENS.
CONTINUE TO UNDERCUT MOS THROUGH THE PERIOD WITH THE NEW SNOW COVER.
CLIPPER SYSTEM STILL ON TAP FOR THURSDAY NIGHT INTO FRIDAY MORNING.
THIS LOOKS LIKE A "TYPICAL" CLIPPER WITH 1-3" IN AN ALL SNOW EVENT.
HIGH PRESSURE BUILDS BACK IN ON SATURDAY WITH BELOW NORMAL
TEMPERATURES CONTINUING.
THE ACTIVE PATTERN REACHING THE LIMITS OF PREDICTABILITY BY SUNDAY.
SUGGESTION OF A SOUTHERN STREAM SYSTEM SOMETIME LATE THIS WEEKEND
INTO EARLY NEXT WEEK. WITH GEFS LOOKING VERY CHAOTIC...HARD TO SAY
MUCH AS TO WHAT MIGHT HAPPEN WITH THIS NEXT SYSTEM.
&&

BACK NORTHERLY TO MINIMAL HURRICANE FORCE ON THE EASTERN OCEAN
WATERS LATE MON NIGHT INTO TUE MORNING...AND STORM FORCE ELSEWHERE
AND ALSO ON EASTERN LONG ISLAND SOUND AND THE BAYS OF LONG ISLAND.

DURING THIS TIME.
WINDS AND SEAS START SUBSIDING TUESDAY NIGHT. EXPECT TO BE BELOW
GALES BEFORE MORNING AND BELOW SCA LEVELS IN THE EARLY EVENING
TUESDAY.
SUB SCA ON THURSDAY INTO EARLY FRIDAY MORNING. THEN SCA WINDS RETURN
AS A CLIPPER SYSTEM DEEPENS WELL OFF SHORE.
&&
.HYDROLOGY...
A MAJOR SNOWSTORM EXPECTED FROM MON INTO TUE NIGHT...WITH LIQUID
EQUIVALENT AMOUNTS OF 1.5 TO 2.25 INCHES.
LIQUID EQUIVALENT PRECIPITATION AMOUNTS FOR THE SYSTEM MOVING
THROUGH THURSDAY NIGHT INTO FRIDAY IS CURRENTLY FORECAST TO BE
LIGHT...MOSTLY IN THE FORM OF SNOW.
ICE ON THE WALLKILL AND YANTIC RIVERS IS CAUSING MINOR
FLUCTUATIONS IN RIVER LEVELS AT THIS TIME.
&&
.TIDES/COASTAL FLOODING...
COASTAL FLOOD WATCH CONTINUES AS IT REMAINS UNCERTAIN IF WE WILL SEE
WIDESPREAD COASTAL FLOODING.
THE NOR'EASTER IS EXPECTED TO PRODUCE MODERATE COASTAL IMPACTS
FOR PARTS OF REGION OVERNIGHT INTO EARLY TUESDAY MORNING HIGH
TIDE. THERE'S THE POTENTIAL FOR FLOODING OF VULNERABLE SHORE ROADS
AND/OR ADJACENT PROPERTIES DUE TO HEIGHT OF STORM TIDE AND/OR WAVE
ACTION.
THE UNCERTAINTY WITH THE SURGE IS IN HOW QUICKLY WINDS TURN FROM
THE NE TO N. AN EARLIER VEERING OF WINDS TO THE N AHEAD OF HIGH
TIDE TYPICALLY REDUCES SURGE IN OUR REGION.
THE MOST LIKELY SURGE FOR COASTAL AREAS IS:
- WESTERN LONG ISLAND SOUND IS 3 TO 4 FT OF SURGE WITH POTENTIAL FOR
UP TO 4 1/2 FT.
- EASTERN LONG ISLAND SOUND IS 2 1/2 TO 3 1/2 FT OF SURGE WITH
POTENTIAL FOR UP TO 4 FT.
- NEW YORK HARBOR AND THE SOUTH SHORE BAYS 2 1/2 TO 3 1/2 FT OF
SURGE WITH POTENTIAL FOR UP TO 4 FT.
BEACH EROSION AND WASHOVERS ARE EXPECTED ALONG OCEAN FACING BARRIER
BEACHES OF LONG ISLAND DUE TO 7 TO 12 FT WAVES AND THE HIGH STORM
TIDE. A FEW EXPOSED WATER FRONT STRUCTURES MAY BE DAMAGED.
HIGH WAVES AND HIGH STORM TIDE WILL ALSO CAUSE BEACH EROSION ALONG
NORTH FACING SHORELINES OF LONG ISLAND SOUND AND ALONG THE TWIN
FORKS. A FEW EXPOSED WATER FRONT STRUCTURES MAY BE DAMAGED.
COASTAL FLOOD WATCH CONTINUES AS IT REMAINS UNCERTAIN IF WE WILL SEE
WIDESPREAD COASTAL FLOODING. THIS MORNING EXTRA-TROPICAL STORM SURGE
MODELS HAVE LOWERED THE SURGE FORECAST...SO THE THREAT IS SOMEWHAT
DIMINISHED. THE TIDE OF CONCERN IS THE ONE OVERNIGHT...THIS
AFTERNOON'S HIGH TIDE IS NOT EXPECTED TO CAUSE COASTAL FLOODING.
THE NOR'EASTER MAY PRODUCE MODERATE COASTAL IMPACTS FOR PARTS OF
REGION OVERNIGHT INTO EARLY TUESDAY MORNING HIGH TIDE. THERE'S THE
POTENTIAL FOR FLOODING OF VULNERABLE SHORE ROADS AND/OR ADJACENT
PROPERTIES DUE TO HEIGHT OF STORM TIDE AND/OR WAVE ACTION.
THE UNCERTAINTY WITH THE SURGE IS IN HOW QUICKLY WINDS TURN FROM
THE NE TO N. AN EARLIER VEERING OF WINDS TO THE N AHEAD OF HIGH TIDE
TYPICALLY REDUCES SURGE IN OUR REGION.
THE MOST LIKELY SURGE FOR COASTAL AREAS IS:
- WESTERN LONG ISLAND SOUND IS 2 TO 3 FT OF SURGE WITH POTENTIAL FOR
UP TO 4 FT.
- EASTERN LONG ISLAND SOUND IS 1 TO 2 FT OF SURGE WITH POTENTIAL FOR
UP TO 3 FT.
- NEW YORK HARBOR AND THE SOUTH SHORE BAYS 1 1/2 TO 2 1/2 FT OF
SURGE WITH POTENTIAL FOR UP TO 3 FT.
BEACH EROSION ALONG WITH SOME WASHOVERS ARE EXPECTED ALONG THE OCEAN
FACING BARRIER BEACHES OF LONG ISLAND DUE TO 7 TO 12 FT WAVES AND
THE HIGH STORM TIDE. A FEW EXPOSED WATER FRONT STRUCTURES MAY BE
DAMAGED.
HIGH WAVES AND HIGH STORM TIDE WILL ALSO CAUSE BEACH EROSION ALONG
NORTH FACING SHORELINES OF LONG ISLAND SOUND AND ALONG THE TWIN
FORKS. A FEW EXPOSED WATER FRONT STRUCTURES MAY BE DAMAGED.
