Or the more obvious they just F'd up the measurement as always.

They did mess up. It wasn't the banding because LGA didn't really get into that (as opposed to southern Brooklyn or Queens) and they measured 3.6. Pretty ridiculous but more of the same.

1.6 central park complete bust..

Seems legit, I don't know where they measure, but walking around in the Park it's about 2" all over.

Nice storm here with 6” or so up to 12.4” on the season.

I "think" the NWS was pretty accurate with this one.  There were a lot of varying forecasts from other entities, but none too far off the mark.  Even though my backyard (Garwood NJ - central Union county) received 3.5", I was a little disappointed.  I was hoping for a little bit of an overperformer.  But with the subsidence at the exact time the heavier stuff was supposed to fall, I knew it was not to be.  Even though the radar showed the "screw" zone, I was pessimistically optimistic that it would quickly fill in as some had mentioned.  At least it's cold, and my fire is still burning from last night...

I don't think there was much of a screw zone. The graupel mixing in during the heavier precip for the first few hours may have hurt us a bit.

There were a few isolated amounts over 4" but most of the 5+ was from Hunterdon over through Morris and west Essex on north and west. Generally it was 3 to 4 south of 78 and dropped off once south of us by 20 or 30 miles.

On the low end of expectations generally but a nice event. It was clear yesterday AM that other than the places hit by the 700mb/mid-level band it wouldn't live up to the higher expectations since this was a disorganized system that couldn't really drive in the Atlantic moisture. 3.5-4" around this area, can't complain.

Yes

I suppose varying waves of heavier precipitation that occurs in almost nearly every storm, rain or snow events, is banding.  However, I think we throw around the term as though one town receives 12" while a neighboring town receives 2".  These would more appropriately be referred to as deformation zones, or areas of intense lifting caused by specific synoptic conditions?  I think this would be an interesting point of discussion on one of the banter topics?

I would debate that central Union county NJ was in a bit of a "screw" zone.  Around 3 PM, when the system was forecast to really start intensifying, an area of subsidence occurred and brought the intensity to a very light flizzle...

3.5 total in Metuchen 

 

Deep winter landscape currently 

 

disappointing total for nyc especially considering the model runs leading up to the event. We very well might break the longest streak without a 4+ snowstorm

Maybe it's 2 inches now after a whole night of compression and settling. Doubtful at midnight last night when they measured it was 1.6 but it's par for the course.

Do you live in Manhattan? 
 

I’m about a mile from the CPK station and I couldn’t measure 2” last night anywhere.  I would have guessed more like 1.8” but it’s not some criminal under measurement.

Still enough to create a winter wonderland with the cold.

Summary: You be the judge of the ensemble performance 8 days ago when this 88 page thread began.  Added a bunch of CoCoRaHs data (as reported) to verify...more or less what happened yesterday-last night.
