Projected qpf output has been steady & consistent up here. Pretty much 0.25-0.35. Factor in high ratios and we have ourselves a decent event. 

If the storm is flatter it might almost help inland areas if the cut off is less sharp due to less subsidence, of course if it goes too far east then we all get nothing...

Going to be plenty of surprises... thing is cranking now.   Bombs away.   Look at the satelite satellite presentation.  Further NE, but this thing is going to set up some incredible rates in these bands with the expansion.  NYC still getting a foot.  Coastal Monmouth and Ocean in Jersey will see pockets of 18 plus.   Good storm.  Beautiful transition from something we discounted less than 36-48 hours ago... and on a weekend none the less.

I agree

Something is weird right now with the models

Pixie dust begins on Barnegat Bay.  Returns should fill in over the next 45-60 minutes.  A band is going to set up north of here within 2 hours.  2018 redux version?

 

Edit : light snow came in like a wall within 2 minutes, and large flakes. Instantly beginning to cover lawn, boat, and car.

HIGHLIGHTS...

* WE NOW HAVE HIGH CONFIDENCE IN A HISTORIC MAJOR WINTER STORM FOR
 EASTERN NEW ENGLAND. WIDESPREAD 1 TO 2 FT SNOWFALL WITH LOCALIZED
 3 FT IS LIKELY FOR EASTERN MA AND RI ALONG WITH BLIZZARD
 CONDITIONS.
* SNOWFALL RATES COULD REACH 2 TO 4 INCHES PER HOUR AT TIMES DURING
 THE DAY ON SATURDAY WITH POSSIBILITY OF THUNDERSNOW ACROSS EASTERN
 MA AND RI.
* IN ADDITION TO POTENTIAL HISTORICAL SNOWFALL, STRONG WINDS UP TO
 HURRICANE FORCE ESPECIALLY ALONG THE COAST WILL LEAD TO BITTERLY
 COLD WIND CHILLS ON SATURDAY ALONG WITH MINOR TO MODERATE COASTAL
  FLOODING.   

DETAILS...

HEAVY SNOWFALL/EXTREME SNOWFALL RATES...

MODELS HAVE NOW COME INTO CONSENSUS FOR A HISTORICAL BLIZZARD TO
IMPACT EASTERN SOUTHERN NEW ENGLAND. EXPLOSIVE CYCLOGENESIS WILL
OCCUR OFF THE MID ATLANTIC COAST TONIGHT, WITH AN IMPRESSIVE 40 MB
PRESSURE DROP IN 24 HOURS AS A SURFACE LOW TRACKS FROM EAST OF THE
CAROLINAS TO THE 70W/40N BENCHMARK. FOR REFERENCE, A BOMB CYCLONE'S
CRITERIA IS A DROP OF 24 MB IN 24 HOURS. AT THIS POINT WITHIN 24
HOURS OF THE STORM, WE ARE NOW IN THE TIME FRAME WHERE THE NAM
GENERALLY PERFORMS WELL DURING AN EAST COAST CYCLOGENESIS EVENT.

WE NOW HAVE HIGH CONFIDENCE IN EXCEPTIONAL TO EXTREME SNOWFALL RATES   
WITH THE POSSIBILITY FOR THUNDERSNOW ACROSS EASTERN MA AND RI.   
SOMEWHAT LOWER CONFIDENCE IN THE EXACT PLACEMENT OF THE HEAVIEST   
BAND, HOWEVER. BOTH NAM AND GFS BUFKIT SOUNDINGS SHOW OVER 50 UNITS 

OF OMEGA COINCIDING WITH THE FAVORABLE SNOW GROWTH REGION. GIVEN   
THAT A DOUBLE BARREL LOW COULD DEVELOP WITH THE POTENTIAL FOR AN EYE-
LIKE FEATURE AT SOME POINT, WHEREVER THE MESOSCALE SNOW BAND SETS UP
COULD SEE 2 TO 4 INCHES PER HOUR SNOWFALL RATES WITH AN OUTSIDE
CHANCE FOR 5 INCHES PER HOUR ESPECIALLY WHEN ON THE BACKSIDE OF THE   
SYSTEM. IF A DEFORMATION BAND CAN PERSIST WHEN THE ARCTIC AIR
ARRIVES LATER IN THE DAY, SNOW TO LIQUID RATIOS (SLRS) COULD BE AS   
HIGH AS 20-25 TO 1. THEREFORE, WE FELT CONFIDENT ENOUGH IN THIS
FORECAST PACKAGE TO INTRODUCE AN AREA OF 24 TO 30 INCHES STORM TOTAL
SNOWFALL. IT IS POSSIBLE THAT THIS BAND COULD SET UP FURTHER WEST,
OR THERE MAY BE TWO BANDS OF HEAVY SNOW WITH LESSER AMOUNTS IN
BETWEEN. EITHER WAY, WE ARE CONFIDENT ENOUGH TO GO WITH A BLIZZARD
WARNING FOR THE POTENTIAL OF BLOWING AND DRIFTING SNOW WITH NEAR
ZERO VISIBILITY AT TIMES ACROSS MUCH OF EASTERN MA AND RI.

STRONG WINDS/BLOWING SNOW...  

WITH 925MB WINDS AT 65-70 KTS OR 4 TO 5 STANDARD DEVIATIONS ABOVE   
NORMAL ACCORDING TO GEFS AND NAEFS SITUATIONAL AWARENESS TABLE AND
COMBINED WITH EXCELLENT MIXING, THERE WILL BE HURRICANE FORCE WIND   
GUSTS AT TIMES ALONG THE IMMEDIATE COAST AND 50-60 MPH GUSTS FURTHER
INLAND. THIS WILL TRANSLATE TO WIDESPREAD DRIFTING AND BLOWING OF
SNOW WITH LOCALIZED SNOW DRIFTS OF UP TO 4 FT OR HIGHER. WITH
TEMPERATURES IN THE TEENS TO LOW 20S, WE HAVE HIGH CONFIDENCE IN
RATHER WIDESPREAD BLIZZARD CONDITIONS ACROSS EASTERN MA AND RI,
INCLUDING THE PROVIDENCE TO BOSTON CORRIDOR. BASED ON THE LATEST
GUIDANCE TRENDS, IT IS POSSIBLE THAT THE I-95 OR EVEN THE I-495 
CORRIDOR ENDS UP WITH A SECONDARY LOCAL SNOWFALL MAXIMA. THE SILVER
LINING IS THAT BECAUSE WE ARE DEALING WITH DRY POWDERY FLUFF, THERE
IS LESS OF A CONCERN FOR SNOW LOADING ISSUES EXCEPT FOR PARTS OF THE
OUTER CAPE AND NANTUCKET DUE TO THE COASTAL FRONT.

POWER OUTAGE POTENTIAL LOOKS TO BE HIGHEST ACROSS CAPE/ISLANDS,
WHERE THE WARMER TEMPS WOULD LEAD TO HEAVIER AND WETTER SNOW AND
CONSEQUENTLY HIGHER SNOW LOADING. WITH 70 MPH WINDS, POWER OUTAGES
WILL BE LIKELY.

THERE IS SOMEWHAT LOWER CONFIDENCE HOW FAR WEST THE HEAVY SNOW
OVERSPREADS AND THIS IS SOMETHING THAT WE CANNOT BE ENTIRELY SURE
UNTIL THE MESOSCALE BAND SETS UP AS THE STORM GETS GOING TOMORROW
MORNING. WHILE WE DO THINK THAT PLYMOUTH COUNTY IS STILL GOING TO
END UP WITH ONE OF THE HIGHEST TOTALS FOR THIS STORM, HOWEVER, THE 
SLRS MAY BE AFFECTED BY THE DENDRITIC GROWTH ZONE'S LESS THAN IDEAL
COINCIDENCE WITH THE BEST OMEGA RESULTING IN RIMING AND THE FACT
THAT THE HURRICANE FORCE GUSTS COULD BREAK UP DENDRITES.

Feels like I've read this before:


HYDROMETEOROLOGICAL PREDICTION CENTER...NCEP...NWS...WASHINGTON DC
2:27 PM EST FRI MAR 02 2001...PRELIMINARY VERSION.

...

WE NOW HAVE HIGHER CERTAINTY THAT THERE WILL INDEED BE THE
DEVELOPMENT OF A MAJOR STORM ALONG THE EAST COAST...MAYBE EVEN A
BLIZZARD...IN THE DAY 2-3 PERIOD.

THE VERY STRONG BLOCK NW OVER THE SOUTHERN DAVIS STRAIT WILL DRIFT
WESTWARD AND WEAKEN SLOWLY OVER THE NEXT DAYS...BUT CONTROL THE
WEATHER OVER NOAM THE ENTIRE TIME.

CONCERNING THE EAST COAST CYCLOGENESIS...MODELS ARE GROUPED INTO
THREE SCHOOLS OF THOUGHT. THE ECMWF HAS NOW JOINED THE AVN/MRF
NOGAPS IN FORECASTING STRONG CYCLOGENESIS EAST OF CAP HATTERAS IN
THE 60-72 HOUR PERIOD...POSSIBLY EVEN A SNOWSTORM OF HISTORICAL
PROPORTIONS FOR THE MID ATLANTIC STATES AND SOUTHERN NEW ENGLAND.

this was worse for me personally

Im going to trust the professionals here and upton still has 7-10 for NYC. I mean this was never NYC's storm anyway but people are overreacting I think to some small shifts east.   

I think 6-8 is still on the table for NYC
