I remember you lamenting the band being just on the other side of the canal and I said it would get there, which it did.

It did. It was a little rough being on the outside looking in for that 3-4 hour stretch, where it was like .5-1.5"/hr while just over the canal and beyond as 3-4"/hr but we did dance with good echoes often...especially the first half of the storm, and last several hours.

Thanks for always keeping good records (with pretty maps )

It'd be awesome if you could calculate return rates/quartiles/means with all your interpolations, @The 4 Seasons.

Are your products still images, or are they vectorized/rasters?

Random, but a colleague sent me an image of your 1888 interpolation yesterday

Nice. 1888 was just based on NESIS and COOP data, it's nothing special just had to go off whatever is out there since it's so incredibly old. We were still riding around on horses, wild to think about. 

Everything was done manually in Photoshop and exported as a jpg. I have that and the original psd file for everything,  almost 2k files of each. So nothing is vector based.  

Thanks for all your help over the years.

Do you get the totals just from this board? I am in Mansfield and I plow in Willington, numbers seem high to me. We had a snow hole here for almost 2 hours in the middle of the storm.

Some are from here but the vast majority are from cocorahs, COOP and climate sites. There's maybe like 20 out of 400 from here on those maps.

COLUMBIA 2.6 S CoCoRaHS 18.5"

WILLINGTON 2.7 SE CoCoRaHS 18.4"

AMSTON 1.7 N CoCoRaHS 18.0"

STAFFORDVILLE COOP 14.0"

and kevin from here Tolland 15.5"

If you have a Mansfield proper snowfall total i can include it

But besides that, your map makes me feel good about my number. That was difficult to determine and I was getting t frustrated because it was more than measuring what fell.

I was too busy plowing to measure anything. It's really the willington one I am questioning. I plow right off of 44 in SE willington and that number seems very high for what I saw there. Tough one to measure with the winds anyway.

Ok. Well If you want my opinion that seems too high. But it’s  not like it changes the overall map.

doesnt change anything but a deletion of a text box, which i can do

Gotcha yea there was a pretty extreme gradient from Windham to Tolland this storm there was 13-15s just to the north and west and 22s-27s to the east, so it looked reasonable to me. Impossible for me to know for sure so thats why its in there. And theres a ton of other variables like you said with wind, the way people measure, how often, etc 

And i see the same cocorahs reports over and over from each storm and Willington is one that never really felt off/slanted in previous storms so i always used them

The more reports i get the better than i can cross check but there was like 6 in Tolland and maybe 6 or so in Windham, that were final anyways. 

[Sled]

Yessir. Just my two cents. Ought to put up or shut up and do my own measurements I suppose.

Hours of 35-40DBZ with good snow growth is 3-4”+/hr. Fact not opinion. He’s off the rails. Maybe something was wrong with the accordion?

So the areas he measured away from his neighborhood did have more snow. Seems they were generally 16-18 new snow otg and a decent amount of old snow which he clearly finds with the yard stick. So I can see the new snow compacting a few inches from the depth when the last flakes fell which pushes the total to say a roughly 20 inches when the snow stopped . I understand by measuring every six hours with those crazy rates , snow settling under its own weight , winds pulverizing the flakes, temps 29-33 causing a wetter snow etc one is certainly going to get bigger numbers for snowfall. But is the difference really ten to fifteen inches making storm total snowfall 30-35 inches? It just seems like a 30-35 inch snowfall would leave a depth of 24 to 30 inches on top of the old snowfall and then overnight and next morning til he got there to measure would find depths around 21 to 27 inches. I have never had a situation like this to deal with so I don't really know. Just seems like reporting 36 inches of snowfall and then not even twenty four hours later a settled depth of 18-19 inches is suspicious. I know the difference between snowfall and snow depth. Listen he is a lot but I think his researching the issue was more than reasonable and doesn't make him more crazy.

I mean you see the pictures of cars buried and it wasn’t just Fall River. Of course they had near 3’ with those rates. It wasn’t that wet either out that way. Temps snuck below 32 early on. Once you get below 32F you’re off to the races. Not to mention that band had great snow growth too. 
 

It also matters where and how you measure. There was a lot of wind. You can’t just stick a ruler in some area and think that’s what fell. Trust me, I deal with this a lot in my area. Also the PVD metars still had over 30” on the ground the next day. If he claims Fall River was legit why wouldn’t the same areas to the west that were in the same band not be legit?

RGEM and ICON really nailed that snowfall spike over NYC north to Danbury.

Ok well that's big if the metars had over 30 the next day of the new snow. My former supervisor and a coworker (Green Hill and Coventry RI respectively) each sent me a few pictures and it looked like at least thirty inches of snow at both places.

Unless he didn't drive all over the place but said he did?? I don't know and its giving me a headache lol. I guess I just wish he had gotten buried.

More food for thought. If that area that was under those extremely heavy returns of 30-40dbz got say 16-24". Then what about all those reports in CT of 16-24" and in Middlesex and Worcester counties up to ORH? Thats basically saying all those reports are too high as well because those areas were well outside the main heavy banding and for far less time, even when they were. Looking back at that radar animation several times, there is no question to me that a large area of 24-40" fell especially when i go back and compare it to something like 2005 or 2015.

Yep, great response there. As I mentioned before, people have no idea how hard it snowed there. Literally hours of the atmosphere choking on snow.

Glad to help @The 4 Seasons!

You could vectorize those images using QGIS (free software). It'd be incredibly tedious though. 

You'd have to geo-reference the images, then trace the contours. I think it'd be worth it
