vortex95

5" Brunswick ME Thursday. 3-6" NNE Friday, now 6-12" for much of NNE Sun-Mon, and two more clippers w/ accumulating snow NNE later next week. Well, unlike SNE, NNE is "only" close to avg snowfall season-to-date, except far N ME which is below. So CoastalWx needs to learn to share, even though he was "DONE" w/ NNE earlier this winter!

There were significant issues at many climate sites when ASOS was installed in the mid 90s concerning snowfall. Some sites like ORH have big gaps in the record b/c of this. So I would avoid F6 data when it is obvious it does not jibe w/ surrounding reports. And even when snow observations were set at climate sites were set post-ASOS, we know just from BOS the issues were still rife. And how about DCA official snowfall for the Bliz of '16?, what a joke when you look at other reports in the metro area.

CoastalWx will LUV the Feb 1995 event snow map!!! "NOR'EASTER '95" was the tagline how WBZ lead their news that day (he has told me that many times), and I think that was the first time CoastalWx realized the cheesy hype wx was becoming in the MSM (Hurricane Andrew and Bliz of 93 not long before were the catalysts)!

So you may want to contact this person as to where and how gets all his snowfall data. Actually, he lists his sources on the snowfall map attached! I think there is a lot data out there you could use to produce in detail many pre mid-1990s events for SNE.

I might actually have saved text files for the biggest storms from the early and mid 90s (PNS and other bulletins). I'll get to that in the next few days, along w/ stuff from individual storms from New England snow books that cover every year from the early 70s to the mid 90s.

Perhaps the mega snow weenies on this group can shed some light here. Snow total reports that always had bugged me from the Dec 11-12, 1992 blockbuster (the one that started it all - meaning ending the overall "lame" snow period 1978-79 to 1991-92 for the most epic period ev-A!) Below is the NWS BOS summary for the storm. The 48" report at Savoy and Plainfield MA I find suspicious, esp. since they are both at an even 4 feet! Also, the 40" at Sandisfield, next town over in Otis had 33" and both towns are very close in elevation. I can believe 36" max from this storm, but not 40"+. On Dec 3 there was a big snowstorm in the Berkshires w/ 19" at Monterey and 15" at Peru (side note: that 19" was the highest single storm snowfall in MA in nearly 5 years), so I have to wonder if the 40"+ totals were a result of including previous SOG. This was before the NWS modernization, which started in SNE late 1993. Before this time, spotter training was not organized and they did not aggressively reach out to the public ("send us your reports!") for wx events. So how snow was measured was all over the place and not standardized. This is significant b/c we can count on one hand how many times since the late 19th century SNE has had single storm snowfalls 40" or larger. Only two I know of prior to 1992 -- 1888 and 1978, the 100 hr storm in Feb 1969 was really close - 39" at Rockport MA). OTHER PUBLIC PRODUCTS..FINAL CORRECTED STORM ESTIMATES..

Before the NWS started issuing PNSs, they used OPUs (other public products). Reports from the early-mid 90s from BOS and PVD can be found here. https://mesonet.agron.iastate.edu/wx/afos/old.phtml Enter OPUBOS and OPUPVD and go back 1500 bulletins.

ZR = FZRA and IP = PL. Precip codes used prior and after METAR format was adopted in 1996 in the U.S.

He didn't. Just his uber weenie status and working w/ him for 10 years warrants a lot of "digs"!

I'll dig out of my archives soon booklets I have that summarize all snow events for SNE from the early 1970s to the mid 1990s. I'll take pix of the more significant ones, and send them along.

CoastalWx probably gives it a "C" b/c "all that cold and all we could get is two lousy 20"+ storms in Weymouth!!" And he was so "done" w/ NNE getting it all so early!

Bookend winter, like 1981-82. Early Dec big S+ (and big bust surprise) and then April blizzard!

Yes the first one, I recall that morning, scud off the ocean up the wazoo. Definitely did not look like a pre-snowstorm environment! Too mild. But the convective nature of the storm did its magic across SNE. Big surprise. The second one R/S mix in Woburn w/ .3" of slush when I left for WSI at 1130pm. Got to Rt 3 in Burlington, S+ and quite a ride. Trees and branches all leaning over on the highway (this was when it was still 2 lanes). Pulled into work, and the power when out. Worked a midshift on backup power. Not too bad. Just whiny ppl call saying Intellicast was not available. Those servers were not on the UPS. I got one caller say "people are gonna DIE b/c Intellicast is not available!!!" Yeah, yeah, whatever, I felt like quoting Butt-head and saying, "Hey, it's FREE asswipe!!!" Not a paying client/customer. Scott was probably mad it was down b/c that was one of the only sites that had radar at the time (NWS radar data was not free on the web until 1999).

Dec 6-7, 1996. Two sig snow nor'easters in two calendar days. That is exceptional. I know of no other so short time period events for the region, at least in the last 50 years. First storm was tightly wrapped 990 mb low that dumped max of 18" at Cornwall CT and 17.6" at Worthington MA (wet glop that stayed on the trees for the next storm). Then a much larger, more classic coastal came in the evening of the following day w/ 19.5" at New Ipswich NH, 18" at Ashburnham MA, and 16.5" at Union CT (wet glop again that turned to rain many area). So the result w/ 900k w/o power, 500k in MA alone. Biggest power outage for NH up to this time. CoastalWx lamenting in Brockton once again I bet for that event. Funniest thing I recall was the huge lines at DD's the following morning of the second storm (Sunday) in places like Bedford MA. B/c it was largely rain here but not even 5 mi N, wet snow disaster w/ no power. So no one could make coffee and were flocking S to get their fix!

Brockton or GHG at the time? Yah, but you just had the Bliz of 97 9 months earlier! "I want everything IMBY no matter what!!!" LOL.

So for the dedicated snow weenies here, what is your take on when ASOS reports UP? I always thought it was IP, but can it be a mix of R/S/ or R/IP or S/R/IP? Never ZR?

Ayer MA SNOINCR 8! Bright-banding was not melting snowflakes aloft, it was giant dendrites making to the surface! This was a watershed event in a way b/c it was then recognized how important the DGZ was (not all snowflakes created equal!) Seriously, DGZ and flake type was not a thing prior, and least in mainstream forecasting. Pretty MEH sfc low as well for this event. Not much wind either.

Most anomalous in terms of weirdness set up I have ever seen for a biggie snowstorm for SNE. Sfc low 600 mi SE of ACK when the big S+ kicked in late night on the 7th and turned the AM commute in a disaster b/c schools were not closed and the area was not prepared. I think the fcst the night before was a general 3-6" in ern MA. IIRC, the ECMWF had the most fcst for the event at 4-8", but even that was 3x too low! Biggest modern day bust for so much snow for a storm in the region. Another one that stands out was 12/23/1997. Fcst was 4-8" at best and we ended up w/ 12-24" for the event. BOS Herald cover the next day, "THEY BLEW IT!" and showed mug shots of all local OCMs! I still have the paper. Also, another big bust 12/5/2005. The CoastalWx special, he recalls that vividly in GHG. Woke up to this wind roar all of sudden from the NW and then when to S+. Small nor'easter very tight but wicked! One of the few times a nor'easter in New England produced 100+ mph gusts (I can count on one had the number of times that has happened in the last 50 years). Usually, only hurricanes here give gusts that high! SNOINCR 9 reported in Andover MA area from a reliable source.

I bet the animated GIFs from "MID-LO" were hot and heavy for this event!!!! LOL.

IMHO, range should be limited to 12", such as 12-24", for a region/area.

6" or bust for Weymouth!

Will CoastalWx eek out another 6" "VIOLENTLY BEAUTIFUL" wet snow pasting? 12z HRRR thinks so! So borderline. The issue is between 850 and 700. Right on the fence for so much of the nrn 1/2 of MA. 1000-850 thickness ok. One thing of note that may make ern MA down to Weymouth a "surprise," the sfc pressure never falls below about 1028 mb at BOS, which very high for a sig snowfall/QPF event. And you can see the sfc high pressure wedge holds strong and tries hard to push SW in ern MA during the entire event. Another thing, such high heights and thicknesses, so more moisture. In fact, the 12z HRRR shows a max of 1.80" rain/LEQ not far S of ORH. That is quite impressive for what amounts to a meager 1019 mb sfc low SE of ACK! And yet another thing, it is quite strong mid-upper level trof (500-250) that passes right over SNE, cold pool and all, and you can see what happens later in the event over ern MA (esp. NE) as the pcpn "hangs back" a bit. Sim IR shows a pseudo-common head. Just sayin' that given high QPF, the ideal track of the 500 trof, and the borderline temps, there could be a "wild turkey surprise" here for more snow than explicitly shown! Edit: And the peak of the pcpn is overnight, which makes an enormous difference for accumulating snow this time of year and give just a few less tenths of a degree to the BL!

And forgettable for CoastalWx as well GHG *yawn*! Worst than 12/12/1992 when he lived in Brockton?! I got 22" in N Woburn that was 100% wet snow, most ever I had seen from single storm.
