March 2011 was a huge snowpack up here of over 40" below 1000ft, but did SNE peak that winter in February? Everyone had a big pack that winter at some point.

Topped out at 28" on 2/28 that year - my avg max depth is 29", median 26". Missed out on the early March dump by about 40 miles - Eustis got 19", I got 2" IP/ZR and a very cold dark house when I got back from a conference at 8 PM (wife was house-sitting near BGR.) Had some 20"+ days Apr 1-2 after the 15" April Fool storm, last event where MBY was anywhere near the bullseye.

yup, #4 all-time..March 1960 is the only other Mar storm in the top 10, but I was trying to see where last week's 13.1" stacks up as far as March or later goes. 

I know will pulled out the March ranking for ORH and BOS somewhere back in the later obs thread... I think it was #4 or so for March for BOS, #1 all time for ORH (22.8")

Anybody have a list of the top March/April snowstorms at KBOS handy?

 

 

Mar 31- Apr 1, 1997...25.4"

Mar 3-4, 1960.........19.8"

Apr 6-7, 1982.........13.3"

Mar 19-20, 1956.......13.3"

Mar 6-8, 2013.........13.1"

Mar 13-14, 1993.......12.8"

I might be missing one but these are the ones over a foot I believe.

Thanks Will.

 

I'm assuming ORH has a much more impressive list this time of year

I think Apr. 6-7, 1982 might have beaten out 1997 in these parts. Not positve though.

Not sure what's the worth of laboring into a analysis wrt to the difference between the operational Euro and GFS, but they are profound.

 

The Euro version has had a giant eastern U.S. signal for 2 consecutive runs, during which the GFS is vastly more than 50% out of phase.   About the only similarity in the two versions is that in the days prior, 5, 6...8, there is a -NAO, west-based blocking.  But after that there's zippo similarities.  

 

The GFS breaks the NAO ridge down, and retrogrades it into the OV, merging with an evolving SE ridge such that we kind of end up spring-like with limited cold variety storm threats during that same time frame that the Euro has a monster.  The Euro on the other hand is much more agressive with a +PNAP pattern, which train-wrecks S/W dynamics up under a longer lasting, west-based -NAO ridge.

 

I'm pretty sure the GFS is the more guilty in this case owing to it's particular bias', but it is just too far out there to have much faith in the Euro just the same.  I will say this much ... the 00z GGEM has an event but it's more of a higher latitude Miller B ...marginal type deal.  Not as powerful either.

Yeah ORH has a ton of 12"+ storms after Mar 1st...here's just the top 10:

Mar 31-Apr 1, 1997....33.0"

Mar 6-8, 2013.........22.8"

Mar 3-4, 1960.........22.1"

Mar 5-7, 2001.........22.0"

Mar 13-14, 1993.......20.1"

Mar 20-22, 1958.......18.8"

Mar 29-30, 1984.......17.6"

Apr 28-29, 1987.......17.0"

Mar 16-17, 2007.......16.9"

Apr 9-10, 1996........16.0"

2013 did quite well...only failing to pass the epic 1997 storm.

May '77 didn't have enough snow to make the top 10 on that list for events after Mar 1st...12.7" was the total. For the date though, it certainly would be right up at the top.

Still ... I think it should be included but perhaps with an asterisk and an explanation, because it was like 20" very nearby in interior els -

EXTENDED FORECAST DISCUSSION



NWS WEATHER PREDICTION CENTER COLLEGE PARK MD



1051 AM EDT MON MAR 11 2013



VALID 12Z THU MAR 14 2013 - 12Z MON MAR 18 2013



CONFIDENCE IS LOWER THAN AVERAGE THIS MEDIUM RANGE PERIOD, WITH



THE ENSEMBLE MEANS NOT QUITE IN SYNC, AND THE DETERMINISTIC



SOLUTIONS WILDLY DIVERGENT. THE 00Z/11 ECENS MEAN--USED AS A GUIDE



FOR THE CURRENT FORECAST--REPRESENTED A MIDDLE GROUND BETWEEN THE



12Z/10 AND 00Z/10 VERSIONS, AND ALSO BORE AT LEAST A PASSING



RESEMBLANCE TO THE MOST RECENT GEFS MEAN. THE 00Z/11 DETERMINISTIC



ECMWF WAS A DEVELOPED OUTLIER WITH THE MILLER B WAVE APPROACHING



THE EAST COAST AT THE END OF THE PERIOD; SO, WILL WAIT TO SEE IF



IT GATHERS MORE FRIENDS BEFORE GIVING IT ANY REAL WEIGHT. THE



GENERAL FLOW FEATURES A MEAN RIDGE OVER THE WEST AND A BROAD



TROUGH OVER THE NATION EAST OF THE ROCKIES. EXPECT ENOUGH ONSHORE



FLOW INTO THE PACIFIC NORTHWEST TO KEEP THE CASCADES AND COASTAL



RANGES WET.



Looks at least through D6 like the GFS may be friendlier -
