Newark airport measures 4.2 inches and LGA also 4.2 inches and right in between the two Central Park, for once, correctly measures 4.3 inches and now someone on social is suddenly concerned Central Park over measures. Amazing.

I received 2.5" (maybe 2.8" figuring in compression), so I would naturally assume Central Park was not going to excced central Union County NJ (about 10 miles south/southwest of Newark Airport).  But the storm was farther north and east, so the CPK measurement is not suspect, in my opinion...

Yeah I reached about 6 here in Lindenhurst, the showers lasted on and off for a couple hours and were pretty heavy gave me an additional 2" from the initial 3.5", with about another 0.6" falling with the light snow overnight between midnight and 5 AM

Can confirm about an even 6 inches in Lindy. 

Happy for the south shore crew. Love to see you guys clean up.

Let's not forget,  they measure and clear the board each time measurement is made,  with how they had sleet and freezing rain, compaction was legit so if the got 4 it would likely not show 4 if any Joe smo stuck a ruler in the snow.  I maybe wrong but that's what my guess would be.  

Yeah I think this is what it is. It can officially be over 4", but be hard pressed to find an actual snow depth to match that this morning.

Which is silly of course. The whole snow board thing is ludicrous. Just measure snow on a table top or god forbid the ground and call it a day. People go a little nuts

I don’t believe they clear the board every time they measure. That was the old way every 6 hours.

Now, I believe it’s clear the board after 24 hours or when there is a change of precip type.

I just got done shoveling and wow, what a job. Very difficult due to the layer of ice under the snow. I had to scrape and scrape so hard with the shovel to get it up. In some spots I had to put salt down to loosen it up before getting it up. A total of only 2 and a half inches here, but it was a very high impact due to the ice. I am going to skip my workout today because I already got it with the shoveling, lol. Hopefully the next winter storm will be all snow for our area. 

Yeah, I tried about 30 seconds of getting that bottom layer of frozen cement up and promptly decided to just shovel off all the loose snow/sleet and then I spent 5 minutes putting salt down, went and did a bunch of errands, and when I came back the cement was melted in spots making removal easy.

Every 6 hours was silly.  The actual snowfall is what is on the ground (or measuring surface), rather than a theoretical depth not accounting for gravity or other physical properties.  And I believe there is an average based on a differernt number of spots, so as to account for variations due to drifting, or is this just for larger snow falls?

I would think water content would be more meaningful than depth.  Not that measuring air has no value.

Was in Long Beach and can say they definitely had as much or more than at my house. Winter wonderland there.

Melted the snow that was caught in the 4" gage down to .59".  That works out to 9:1 on our 5.3" snowfall.  Not surprising as I noticed a lot of small crappy flakes for most of the storm.

Second snowfall in a row with light winds where the catch in the gage was quite accurate.

Just about all of the models had us around or over .50 LE, including the NAM.  A couple runs of the GFS were .8 or .9, but otherwise the qpf modeling for LI was pretty consistent and quite accurate.  The snow map algorithms were not as consistent or accurate.

Yea this was a heavy dense snow.
