I thought I was in the Twilight Zone when I was arguing with some posters who think he's an awesome met. I said he's great with patterns, but overhypes storms and they asked me for "proof."

I do think that this storm can deliver your second HECS and one thing I've noticed about JB is he does much better in snowier/colder patterns than he does in others.

Noooo, disagree vehemently. Major, not historic.

Not sure where the specific pics are from (what town, etc), but this was in Quebec and this season was the second snowiest winter on record.

Here is what I could find on it:

The most remarkable amount of snow was in Ottawa, where an excess of 432 cm fell just 12 cm short of the venerable snow record of 444.6 cm in 1970-1971 – an event often regarded as a 1,000-year occurrence. Ottawans did not see bare ground for 143 consecutive days, from November 21 to April 11. This was the longest stretch on record and four days longer than the string of 139 snow cover days in 1970-1971. Less than a week before the first day of spring, snow on the ground in the nation's capital was at the season's deepest – 87 cm. During one particularly brutal four-day stretch in March, the city was pummelled with 73.2 cm. And while the snowiest month in history occurred in 1970-1971 (159.5 cm in February), Ottawa did claim its second- and third-snowiest months ever this winter (121.0 cm in December and 113.4 in March). Montreal's 371.4 cm also came close to breaking its 1970-1971 record of 383.3 cm and – like Ottawa – could claim December and March as its second- and third-snowiest months (respectively) on record.

I thought Ottawa's peak depth would have been more like 50" that winter....not 34"...WTF.

Can't be right.

Area Forecast Discussion

Issued by NWS Upton,NY

403 pm est mon jan 24 2011

CONCERNS ABOUT MODEL GUIDANCE ARE HIGH DUE TO EXTENSIVE CONVECTIVE

PCPN BEING GENERATED THROUGH MODEL PARAMETRIZATION. THE LATENT HEAT

RELEASE AND THE DYNAMIC BUILDING OF THE DOWN STREAM RIDGE ARE

AFFECTED. THUS...WHILE MODEL TRACK IS CLUSTERED NICELY...HUMAN

UNCERTAINTY REMAINS HIGH FOR THE ACTUAL TRACK. THE NAM IS AN

INTERESTING EXAMPLE...AND WHILE BEING DISCARDED FOR FORECAST

INTEGRATION...IT IS RIGHT OF THE ENSEMBLED TRACK AND PRODUCES ZERO

QPF.

HAVE CONTINUED BASICALLY THE PREVIOUS FORECAST UNTIL THINGS BECOME

CLEAR. NOTE THAT NOAA WINTER RECONNAISSANCE IS BEING FLOWN FOR THIS

SYSTEM IN THE GULF OVERNIGHT. THESE CRITICAL OBSERVATIONS WILL GET

INCLUDED INTO TOMORROW`S 12Z AND SUBSEQUENT MODEL CYCLES. THUS

EXPECT THINGS TO BECOME CLEARER TOMORROW. NO WATCHES WILL BE ISSUED

THIS AFTERNOON AS WERE STILL OVER 48 HOURS FROM POSSIBLE WARNING

CRITERIA.

PTYPE IS A MAJOR ISSUE WITH THIS EVENT AS MODEL SOUNDINGS SUPPORT A

WARM NOSE ALOFT. EVEN INLAND LOCATIONS SHOULD EXPECT AT LEAST SOME

MIXED PCPN. A WINTRY MIX APPEARS TO BE THE PREDOMINATE TYPE WITH MORE

RAIN TO THE EAST. OF COURSE WITH TRACK AND QPF AMOUNT HIGHLY

UNCERTAIN...ANY SNOW AMOUNT FORECAST IS EVEN MORE UNCERTAIN. IT DOES

APPEAR THAT LIKELIHOOD OF WARNING CRITERIA SNOW IS LOW...EVEN

INLAND.

This is HECS potential, but not 1978 potential..nothing does.

I know this is slightly off-topic, but took a drive yesterday out west. We drove from Cambridge, over to Brookline, through Coolidge Corner, then out to Wellesley, Newton and into Natick/Sherborn.

I was amazed how much of a difference between Cambridge and Brookline. Seemed like a pretty palatable difference in snowpack. My end point was Sherborn and the snowpack out there was as deep as I can remember. The only thing that seems similar (excluding my 4 years in Syracuse for school) to this is the 95-96 winter. Everyone seems to be buzzing about where to put the snow if it snows anymore (which looks increasingly likely) -- reminds me a lot of that winter.

Can't wait to see what BOX has to say about this next storm.

I drove Boston->Brookline->Newton->Needham->Dedham to Norwood yesterday.

Beautiful, deep satisfying snowpack everywhere.

Deep, deep winter.

Even broken clocks are correct twice a day.

I'll let verification do the talking...I muddeled this thread enough rebutting your whiff concerns right before the 00z GFS caved.

BM....maybe a hair inside.

I've said for two days a track near the BM plus/minus 30 miles. Yesterday you took some of what Scott said out of context, you've done it now every 6-12 hours with me. You were all over the place with the 12z Euro muddling that as many others have said and that's fine it's your choice, but "whiff" concerns...I've said all along I favor the extreme tracks versus the "cape cod/ack" specials of this winter.

---

Anyway, the RGEM has the same split moisture shield, not all that different from the 18z NAM. There's a huge dryslot up to Hatteras that's gradually being wiped out, and a dryer punch up into NJ with the main moisture shield offshore but wrapping as the entire thing develops/washes out the dry slot offshore. Different, yes, but not tremendously so. I don't think there's any doubt it's also hinting (maybe feedback too who knows) at some intereference from small vorticies coming out of the Gulf well east of the main system.

Hey Ray, not disagreeing with the potential for Boston but doesn't HECS imply a greater portion of the E. Coast (major cities etc) is affected. I might be wrong on that though.

Well, it won't be high on the NESIS scale, but I think it could go HECS for a good chunk of SNE, though MECS level is more likely.

Can't be right.

EPIC BLOWTORCH......janaury 2008 (you've seen Will's pictures i am sure), melted off 90% of the nearly 3 feet depth as well as the associated snowpiles that come with it. and i mean, it was total devestation. before that we had the Grinch Xmas storm.......so in mid-jan, we started from scratch after 75 inches down. like totally scratch.

:axe: :axe: :axe:

that was the difference between us an quebec city that year, in terms of depth

ironically Ray, with all that snow, it ended up being one of the biggest regret seasons ever....

1. we fell short of snowfall records by as close as 4 inches

2 . what could have been without the torch

thats why for me, 92-93 is still the greatest winter ever around these parts.

(1970-71 is actually the greatest statistically)

That wasn't me....it was Steve.

I muddled nothing up; differences were trivial between the 00z run and 12z....the issue is that trying to extraploate early on makes it difficult to discern subtle differences.

You're simply wrong.

I do think that this storm can deliver your second third HECS and one thing I've noticed about JB is he does much better in snowier/colder patterns than he does in others.

I thought Ottawa made out better than Quebec....wow.
