That map severely underdone for Nassau County. Sorry, most of the county has more than 6”. Also CT had many spots over 6”…I guess the map shows the areas that got the most, but the amounts are way underdone 

I dont understand why maps arent made based off of spotter reports

Thanks Don, so this was a 6-7 inch event here.  I'm trying to remember what storm we had that winter that was a 10-11 inch event (not the Blizzard of Dec 2003).

The only other event was in late jan and was an 8 to 12" event but a few spots may have done better

Thanks Don!  I see why I confused the two.....they both happened in Jan 2004 and they both ended in the morning!  So the mid Jan 2004 event was the one with the extremely high ratios and the late Jan 2004 event was the one with the pink snow?  I still remember the wide variance in snowfall..... Far Rockaway had almost 11 inches while JFK was closer to 6.5!  Did this one not have the extreme ratios of the prior storm and were the temps not as cold?  I think this was the pink snow storm that I still remember all these years later.

 

[BombsAway1288]

What were the ratios at LGA for this? 30:1?

[wdrag]

Will add CoCoRaHs two day around 10A and probably repost these graphics below on the initial thread for review. In essence... our first week of January snowstorms in the northeast.

No negative NAO and no positive PNA. The indices are nice but I still think it's location-location-timing-timing.  

Anyone look back at the NAM banding graphics for S+.  Pretty interestingly accurate.

It looks like the ASOS may have undermeasured the actual liquid equivalent of the snow. The NWS has noted this at certain ASOS stations in the past  during heavy snows. Other North Shore observers picked up nearly .50 of precipitation

 

https://storymaps.arcgis.com/stories/96964b6457794d2196dff24d68d4688d

 

Sometimes the Automated Surface Observing System (ASOS) can struggle to melt snow for liquid equivalent in heavier snowfall.

I'm no longer up to speed on ASOS snow melt but I agree it could still be a problem. 

 

I just want everyone to see those indicies where these events occurred Jan 3 and 7 and again, helpful NAM Banding guidance showing potential 1+"/hr. 

[wdrag]

Here is the wrap up...CoCoRaHs and NOHRSC analysis. Hopefully this is acceptable. 

NAO and PNA indicies at the time. Click for details.

Thanks. Didn't even know this was an issue. LGA was likely closer to 20:1 or less. Still very impressive for being down on the water basically.

Looks like down here on the south shore it was closer to 10:1.....I wonder why?  The trees here are full of snow, just like a heavy wet snow.....8.1 inches on 0.90 precip? Wow, that's actually, 9:1, might explain the lower snow totals down here?

Based on Walt's numbers.....

Chris do you have the official JFK ratios?  Either way the snow down here was really wet and caked all the trees until they were bent over.....until the wind started up and blew it all down lol.

Here is the wrap up...CoCoRaHs and NOHRSC analysis. Hopefully this is acceptable. 

NAO and PNA indicies at the time. Click for details.  

Walt.... 8.1 inches of snow here on 0.90" precip jives well with how heavy and wet the snow was here, all the trees are literally caked in snow!  9:1 ratio.....I wonder what it was at JFK?

JFK: 8.1" on .9 precip    but Flushing Meadows  7.9" on .53" precip.  

Didn't happen they were both along the same band. 

The .53" is probably correct for both sites. Gives about 15:1 ratios.

I'm no longer up to speed on ASOS snow melt but I agree it could still be a problem. 

 

I just want everyone to see those indicies where these events occurred Jan 3 and 7 and again, helpful NAM Banding guidance showing potential 1+"/hr. 

Just based on my own experiences with my standard 4" COCORAHS gauge, which might not be a valid comparison, they catch rain a lot better than snow.  At the time I measured 9.1" on the ground yesterday, there was an uneven (stacked higher on one side) 2" of snow in the guage (I had removed the center and top prior to the storm).  I'm not sure what the physics/mechanics of this is, but I've seen it many times.

I emptied the paltry catch from the guage and used it to get a clean core of the snow on the ground which melted down to 0.65", a hair under 15:1.

The snow depth here this morning was 6", so that 15:1 stuff compacted quickly.

Wait what, the JFK number keeps going up? I thought it was 6.2" lol.  Did the NYC number go up too?  Where is the final report?

Shows the typical nw Suffolk snowfall jackpot zone well.

Thanks for the feedback... I'm un sure of NOHRSC practices but am sure they use filters and the longer we wait after the event ends, the more complete the data set.  We in the NWS could produce these types of maps back in 2018, but it's a bit time consuming ensuring the data is correct. Staffing and other priorities may preclude?

Yes low on the priority list haha

The 8+ amounts looked common from LGA east to Port Jeff. Crazy difference between LGA and Central Park-4” difference in a few miles. 

The jackpot locally may have been N Nassau. A couple of 9” amounts there.

I think our snow was wetter here on the south shore.
