I like his map and the numbers on it. You’ll always have some variation in this type of storm, as long as the outliers are gone it’s perfectly fine and within margin of error. His map looks good. 

As I stated earlier his map is definitely good, but the 30+ zone will be slightly smaller in area coverage than what his map includes based upon NOAA and the National Weather Service  in Norton.

Thanks. What's your thoughts on that 22.5 in S. Harvard?

Why do I care what they have? They are including ridiculous amounts in their PNS.

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.

Blue Hill had 17 on the ground day before 24 total day of 28 otg next day. Its science

Thanks, figured. Only reason I included it is because it's not that far off from the surrounding 18-19" reports. 

I'll be doing a third update tomorrow

If you have any more you think are sus or missing lmk

Yeah, one day cocorahs totals for one and that's not the half of it

NWS has a great page for the storm.

Radar loop as well as surface map loop.

So a net increase of 11 inches from a snowfall of how much?

ill have all that up tomorrow with NE sfc map loop and radar loop, as well as a bunch of other images, satellite, H5, snowfall totals etc

I'm working on a third, and hopefully final, update to the Blizzard snowfall maps

This map you have here is shows why the area of 30" + by NOAA/National Weather Service in Norton have a more conservative swath. They are very particular about specifics. They don't like 5-7" differences in a town over, not to mention in some of the same towns. So, as I stated before they data cleanse and smooth over the numbers. 

I don't doubt that at all. I plot and do all the contours by hand for every storm. I don't have software to feed in a bunch of data and auto generate a snowfall map from averaged/smoothed data. A lot of the NESIS maps are conservative and in some cases way too conservative like February 2013 where there is no 30"+ area over CT despite a very large area and many many reports of 30-40". @ORH_wxman can attest to that, we were talking about that a few weeks ago. That's just one example.

So i knew the NESIS map would be a bit lower/conservative, every map is going to look a bit different. However even with that being said there are some glaringly obvious problems with the current storm. There is a small area of 4-10" near Danbury which i am certain was well over 10" being on the eastern edge of that deformation band. Most of the reports around there are 17-22" and on the low end 12-15" so there's no reason why a hole of sub 10" should be there. Just one example. The area of 20-30" should also be much wider over NJ west and south of NYC, even with smoothing considered, many reports of 20-30" in Monmouth and Ocean counties away from the immediate shore.
