A-L-E-X Posted December 27, 2010 Share Posted December 27, 2010 It really shouldn't have any affect since procedure is to let it build up on the board for 6 hours, then clear it. Assuming they followed standard procedure, their measurements were proper. Now the SITING of their measurements is possibly another story altogether, but Alex and Tony Gigi know much more about that than I. Will told me about it-- I gather he knows the person who does the measuring. BTW, as an aside, I was able to locate the exact location of the JFK ASOS, and its near the southeastern part of the airport, not far from the Nassau Border (North Woodmere is on the other side.) It's like a few hundreds yards from the Bay! Link to comment Share on other sites More sharing options...

SACRUS Posted December 27, 2010 Share Posted December 27, 2010 whoa. you learn something new every day..... monmouth and mercer have a common border. i never noticed that before. meanwhile,,,,,,,,,, sitting at 19" here. no heavy stuff in the last 2 hours or so. East Brunswick looks to bein the better bands now? Link to comment Share on other sites More sharing options...
A-L-E-X Posted December 27, 2010 Share Posted December 27, 2010 JFK I had a feeling over measured, that 16-1 ratio sort of proves it. What I dont understand is how can that liquid equivalent be so low-- is it possible that is wrong? How do they measure liquid equivalent in a snowstorm like this, SG?

How do they measure liquid equivalent in a snowstorm like this, SG? I believe they just take a core of the snow with some device used to measure liquid equivalent Link to comment Share on other sites More sharing options...

nzucker Posted December 27, 2010 Share Posted December 27, 2010 Dobbs Ferry, NY SN 22.2/20 12" total snowfall... It's been a bit frustrating being on the edge of the mega band in NE/C NJ but still a great storm...winds were probably gusting near 60mph in the woods behind our house at 450' elevation. Incredible dynamics and still a few more inches to go. Totals won't rival February 25, 2010 in this area although its cold and winds certainly exceeded that storm.

famartin Posted December 27, 2010 Share Posted December 27, 2010 Do you know how liquid equivalents are measured in storms like this? Is it indendent of the manual snowfall measurement? Is it automated? ASOS is not good at water equivalent of snowfall, though not all ASOS's are alike. The old style ones with heated tipping buckets are the worst... TTN measured 0.06" yesterday. I know we got screwed but not THAT badly ;-) I melted just about a 10:1 ratio, 0.87". However, even the new AWPAGs, which are weighing gauges with heated orifices, have trouble because they are so exposed, they have real trouble catching the snow. Procedures for correcting this problem vary from airport to airport and WFO to WFO. Some have the snowfall observers measure the liquid equivalent directly in a manual gauge (what I did here this evening), and use that. Others will just make an estimate. I couldn't tell you what procedure occurs at the NYC area airports, though I'd suspect its the former. Link to comment Share on other sites More sharing options...
Dark Energy Posted December 27, 2010 Share Posted December 27, 2010 Yea that is terrible. Been wondering when someone from that area was gonna post here. How much snow have you gotten so far? I measured a couple hrs ago about 4 inches. thats it. but im sure the top layer has blown off. I would estimate at least 5.5 or 6 so far. it's been snowing since 11am here.

Absolute Humidity Posted December 27, 2010 Share Posted December 27, 2010 This is pretty crazy considering 2 days ago we were not even sure if we would see one flake and now looks like some partsapt Nj are trying to make a run at the state record of 33". Not here IMBY, I'm just outside the heavy Monmouth banding yet still have measure 20" avg, incredible. Link to comment Share on other sites More sharing options...

A-L-E-X Posted December 27, 2010 Share Posted December 27, 2010 I believe they just take a core of the snow with some device used to measure liquid equivalent Oh cool, like the way scientists take ice cores up in the Arctic. So do you think they would measure that every 6 hours like they do with snowfall or is that an hourly measurement? Sorry for all the questions, Im just trying to figure out if the core is the same thing they use to measure the snowfall with. Link to comment Share on other sites More sharing options...

Not here IMBY, I'm just outside the heavy Monmouth banding yet still have measure 20" avg, incredible. The state record is approx. 35" from Cape May NJ (of all places-- the southern tip of NJ lol) from Feb 1899. There was a disputed report of a slightly higher total in Jan 1996, which was refuted Link to comment Share on other sites More sharing options...

Windchill has been near zero here. Brutal. Haven't been outside in a couple hours, but I'm sure we'll see at least a foot here in Sussex County (Vernon). Surprised to hear about the low snow totals down in Hunterdon County. I guess I was just far enough east to still get a decent dumping. Link to comment Share on other sites More sharing options...

Manny Posted December 27, 2010 Share Posted December 27, 2010 Once the radar filled in over the City, all hell as broken loose. Extremely intense winds with Moderate Snow. Could add on another 4-5" when all is said and done, but not as impressive as John's totals. LOL Link to comment Share on other sites More sharing options...

In other words, Ray, liquid equivalent measurement of snowfall is probably less accurate than actually measuring the snowfall? Sounds like your numbers, done manually, are a lot more accurate.

tmagan Posted December 27, 2010 Share Posted December 27, 2010 As I said before, there will be debate about actual snowfall measurements from this storm for many years because of the extreme wind, unfortunately we may never know the true measurements.

A-L-E-X Posted December 27, 2010 Share Posted December 27, 2010 Wow, just 5-6 in NWNJ...I think I forecast 11 or 12 for KFWN. Some interesting things happened with this storm. 1) Western fringe was displaced eastward 2) Axis of heaviest snow was displaced westward. I wonder if the storm's track had anything to do this; with two opposite things happening, I would think the storm's rapid intensification was the cause of this moreso than the track.

Dark Energy Posted December 27, 2010 Share Posted December 27, 2010 Wow, just 5-6 in NWNJ...I think I forecast 11 or 12 for KFWN. yea, we never got into a mega band. im in north central hunterdon, near I78 and i can tell you i can drive out of my drive way tomorrow no problem. winds are gusty but nothing like they are seeing along the coast so i have to think some has blown off the top layer of snow. the last models i saw last night had .75 for my area under a tight gradient. so far, that is looking good, if not a little too high.
