Timing? Just as I drove by the speed camera on Northern Blvd on my way back from the gym in Great Neck I saw a flash. I think it was lightning as I was only going 29mph in a 30mph zone. Anyway 1" on my car in Great Neck and it looked like an inch on the ground in Great Neck, a little less here in Douglaston with light snow falling.

Only time I’ve ever witnessed thunder snow was the 12/30/00 storm. Would be awesome for it to happen here tonight.

Moderate snow with fat snowflakes in Brick, just started to snow in the past 30 minutes and streets are getting covered already.

And this is being described as a “weak” storm. Imagine if this was deepening rapidly

Meanwhile neither JFK/LGA reported TSSN, shows you how you have to be very close to where its occurring to hear it

The beginning of that band dropped me 2 degrees and ended the graupel / mix and absolutely started ripping snow here. That has to help the city / LI. The rates are high.

Bloomfield, NJ

EWR has 2 on the ground, LGA/JFK have nothing as of the 00Z METAR.  This may be an event where NYC reports way more than LGA/JFK do due to temps being cooler in the park 

[Allsnow]

Where is @weatherpruf? 
 

it’s ripping

Makes no sense though based on GFS track, GFS has N'ly winds and a T/Td at EWR of 32/24 when snow moves in, would probably be down to 29 degrees pretty fast and never move from there

In retrospect, this ECMWF AIFS forecast made total sense.   

EWR went below freezing this evening just before 7 pm with 2 inches of new snow on the ground for the storm (so far).

The AIFS (AI model) had the warm layer properly forecasted 60 hours in advance.  The Google Graphcast had an even longer lead time, and the GFS MOS and 1000 hPa GFS charts eventually also showed the warm boundary layer near the coast.  

The AI models (including their temperature forecasts) are to be respected, in my opinion.  The models did not fail in the situation. 

I'm glad the end of this storm has a good band of moderate to heavy snow more many people.

Snowing heavily here wow
