LGA ended with 7".

So after 4pm, they received 2.4" more snow.

NYC somehow only ended with 5.1". Only .8" after 4pm. 

Bad measurement.

It was 6.0 here, it was 5.8 at 7pm and then another 0.2 fell.  I have no idea why it always seems they miss that 7pm measurement.  Its always that particular one that seems wrong.

If they measured at 7pm, they had the same powder snow falling that Queens had until 10pm. LGA added .7" of powder after 7pm and JFK over 1" more after 7pm.

Even prior to 1993 the NYC measurements were not great for whatever reason.  That was NWS staff back then too I believe.

Probably just need to average the local sites out to get a better representation of snowfall. We already look past the artificially low high temps there due to the vegetation.

NYC got less then JFK and LGA though. Further west.

If EWR received 5.8", KNYC was probably 6"-6.5".

it's a disgrace...almost 150 years of record ruined by none weather people...

Not only that. It was the 1st 6"+ snowfall with a +Ao, +Nao and neutral PNA. But it won't show in the KNYC records. But at least 2 NYC stations, JFK and LGA verified that.

We should probably just take the highest snowfall total out of EWR..NYC..JFK..LGA for classification in reaching various benchmarks like 6" 12" storms for the metro.

Local sites like ISP and BNL for Long Island. That way people don't worry so much about Central Park in classification of our local winter storms.

So this will go down as reaching the 6" benchmark for NYC snowstorms.

someone other than myself could go over past snowstorms from the four big obs sites and do an average for area snowstorms...Reading old stories of the 1800's and early 1900 snowstorms from old newspapers show that measurements from that era are much different than what was recorded for Central Park...1892-93 had 77" and 1893-94 had 37" in February...January 1893 had a 17" snowstorm in lower Manhattan but much less in the park...

LGA: 7.0"

JFK: 8.2"

NYC: 5.1" - RIDICULOUS

ISP: 9.7"

BDR: 5.7"

EWR: 5.8"

When the under count at Central Park is this obvious like this one is I always send an e-mail to NOAA pointing it out and they do always respond. Usually they say they are aware and sometimes they even adjust the amounts several days later. If more people would do this they might stay more on top of it.

For purposes of illustration concerning the visibility yesterday during the most intense snow band in my area, below is a photo from the heavy snow and another from this morning. I wasn't exactly in the same spot (the trees on the left were on the right in this morning's shot), but the location of the trees should provide some context into the distance and visibility.

We could do that. And anyone who wants to compile the snowfall data from spotters at points between the official sites also.

I am a bit disappointed that the NWS seemed to have erased the old OKX LSR's from 2000-2010. There is now only very sparse

data until 2010 and after. Maybe they ran out of room on the OKX official site.

Would be nice if they adjusted the temperatures there and published them to account for the vegetation shading the sensor.

I wonder if they kept an old back up temperature sensor above the canopy on top of the castle?

Since they always under count snowfall totals, maybe this is their way of compensating on the other side.

Incompetence in one area breeds incompetence in all areas.

It's too bad that ASOS wasn't put in a section of the park with a clearing away from vegetation.

Yup.  Ridiculous.  

 

They really don't do anything right when it comes to trying to provide the most accurate wx statistics for NYC.  There's no way this site should be used for the climatology of NYC. I'd be ok if they just starting using LGA at this point.  

 

Until they clear away the vegetation for accurate temperature readings and start measuring snowfalls correctly, I see no reason the NWS should use this site.

And to think Philly's official stats comes from Jersey!!! (National Park, NJ which is across the river from the airport) So they could just as easily change NYC as well.
