The thing is you have weenies like us clearing huge amounts of fluff every 6hrs and then the general public sticking the yardstick into the driveway at random times. When the PNS is showing a handful of reports a bit over 20” for the high range in a populated county and then a report comes in of over 30” it definitely stands out. That Wilmington 22.5” cocorahs report is just as fishy with about 3.00” of liquid reported. They reported 21.4”/2.75” for 7a-7a....I don’t think so. The other Wilmington cocorahs only reported 17.8”/1.22” for 7a-7a so the obs are all over the place. 

But you’re going to have trouble with people actually believing it since even the highest cocorahs reports are 20-25”. It’s simply just differing methods and that’s the nature of the beast. You’ll just have to deal with the skepticism. :lol:

Anything under 15 to 1 up in that area that was also measured last night isn't credible IMHO. That band was blower powder. You need to be either outside the band with crappier snow growth or right on the beach where the snow stayed pretty wet to have ratios under 15 to 1. I can buy it maybe if you didn't measure until morning. Given the nature of the snow in that band...if you were swiping every 6 hours, your total is def going to contrast more with the "yardstick in the ground at the end" method more than normal. In a typical dry cement windblown blizzard, the difference might only be 3 inches. It could very well be double that in a storm like yesterday if you were being very diligent.

22.5"....accumulated another inch, and LOST another 1.5" depth. 

The old school weenies that like to measure at the end of the event can come in here and tell us those couple of inches overnight never happened.

Probably going to shatter that record.

You would think so....but the 2nd half of March can shut down quickly sometimes even when things look pretty good for more threats like they do now. Climo would get them there, that's for sure.

"General Public" :lol:

In fairness, in my hierarchy of reports I put general public before social media. 

In extreme cases when someone doesn't go to spotter training (@dendrite), we'll just give them a spotter number and enter it on our own when we see the report on a message board.

Exactly.

Thanks.

I wish they would go back to just sticking a ruler in the ground...I would have said 24.7" and be done with it.

That’s what I do . It’s to confusing the other way and reports all over the place . To the public that’s all that counts anyway . The big storm for me last week dropped  24 plus in my area (northern nj morris county )My depth was 23 and that’s what I reported

My chuckle was more around Ray getting the label of General Public.  Feels like he's deserving of more just based on his dedication, but there's no other appropriate bucket for him.

 

Side note:  do you know why the reporting from the PWM ASOS site is inconsistent in terms of when you all report it?

I don't know why it drops out of the PNS sometimes.

That's on me...I need to do the training....that,  graphics and seasonal temp anomalies are on my summer to do list.

Oh, yea...and marriage.

I'll add to the list for ORH....

21.8" yesterday was a daily record, but it also put the monthly total at 40.0".....this is the 2nd snowiest March on record for ORH only behind March 1993 which saw 44.1".

That's hugely impressive. Worcester has a real shot at setting a new record.

If you want to compare real impact...just measure the snow water equivalent and go with that. 10” of 8:1 has more impact than 15” of 30:1. That gets rid of most of the method issues.

I have Advanced Skywarn training from NWG GSP office, but that was a warm-season training. Definitely need to do cold-season training to get my spotter ID.

Mekster and I both got hammered with NoPoles in Canada so I think that’s how I got mine.

Snow pack is extra impressive looking because we still had all that low ratio cement from the previous storm last week before yesterday happened....so while 2 feet of snow looks impressive no matter what, the piles and everything are starting to give me flashbacks to 2015.

LOL.  I did mine way back in 2005 with Max(CapeCod04)  Think we did it at the Natick Town Hall.  May have been Eleanor and Joe that did the presentation.

I think i did mine before that even, It was at the Auburn Public Library..........lol

PWM actually has 2.5" officially since midnight, so that's 9th snowiest.

Public Information Statement
National Weather Service Taunton MA
827 AM EDT Wed Mar 14 2018

...BLIZZARD OF MARCH 13 2018...

Blizzard conditions were reached at many locations across
southeastern New England during the storm on March 13.

The definition of a blizzard is that falling and/or blowing snow
reduces visibility to below 1/4 mile along with sustained winds or
winds that frequently gust to 35 mph or more...and that these are
the predominant conditions for a period of 3 consecutive hours.

When reviewing whether a particular observation location had
blizzard conditions, we counted visibilities equal to 1/4 mile,
since that is quite low for an automated visibility sensor to detect.
We also made some subjective decisions. For example, at Marshfield,
MA, there were significant wind sensor outages, but mesonet data
from Duxbury Bay were used as a proxy and indicated nearly
continuous gusts at or above 35 mph during that time period.
At Martha`s Vineyard, there was a 3-hour wind data outage, but
mesonet data at Vineyard Haven indicated continuous gusts at or
above 35 mph during that period. At Plymouth, blizzard criteria was
met just before a complete data outage occurred, lasting most of the
day, which made the duration undeterminable.

The following observation sites were determined to have had a
blizzard...

HYANNIS, MA............10 Hours 35 Minutes...from 730 AM to 605 PM
MARSHFIELD, MA......... 9 Hours..............from 855 AM to 555 PM
FALMOUTH, MA........... 8 Hours 40 Minutes...from 715 AM to 1055 AM
                                        and from 1155 AM to 455 PM
MARTHA`S VINEYARD, MA.. 8 Hours 22 Minutes...from 800 AM to
                                             approximately 422 PM
BOSTON, MA..............6 Hours..............from 840 AM to 240 PM
NEWPORT, RI.............4 Hours 20 Minutes...from 850 AM to 110 PM
PLYMOUTH, MA............>2 Hours 53 Minutes from 732 AM to 1025 AM
                                             but then power outage
