Although you are in theory correct, the Dec '92 storm was pretty far west....moved over Chesapeake Bay, IIRC...before eventually moving northeast...IIRC, even up at Greenwood Lake State Park...on the Passaic / Orange County border....though they ended up with about 14"...it kept changing back and forth from rain to snow and back again...and they have some elevation there, too. One would probably have to go as far NW as High Point State Park to have seen an all snow event out of this thing. NYC would probably have gotten something like 4 - 6 inches out of this one if it were in March...the track is what killed it more than anything else.

13 inches thursday overnight to friday morning at 32 degres, wet snow no accumulation from about 9am through 3pm that day, then then temp dropped and we accumulated another 4-5 inches through Saturday. This is at 830 feet in orange county.

Yeah I think the station I cited was right on the NY / NJ border...you must have been a bit farther north...and I would have to double check the altitude.

So maybe we should do snowfall predictions at the local stations for 2012-13...that would be fun and could kill some time....

FWIW , This is NOT going to be a torch winter . Not one serious trader in charge of managing huge Ag and Energy portfolios out 6 to 9 months

have any internal view of a warm winter in any way . Havent seen doomsday views , but slightly colder in the northeast and normal to above snow seems to be the opinion

Way to early to be prediciting snowfall totals - impossible - think they would have learned their lesson from last years fiasco - but accuweather is in the business of hyping everything to try and make a $.Still an even chance of a "NINA Hangover" while on paper a weak NINO favors above normal snowfall the winter of 1976 is an example of NiNO following NINA and not delivering - cold fall and winter but not above avg snowfall

Its likely that we're going to see some sort of carryover effect for sure, the 02-03 analogs are simply not going to work because we were coming off a weak Nina/neutral setup, this time we're coming off a very strong La Nina...without going into depth and just looking at the past 30-40 years purely at the ENSO setup where we saw a weak Nino following a relatively long La Nina period that was at times moderate to strong we have 76-77 as you mention above and thats about all....86-87 could sort of qualify but 85-86 saw a somewhat weak or near neutral stretch so you could argue the southern branch was probably more active in 86-87 than it may be this winter. If I had to forecast snow relative to normal this winter just using the ENSO state I'd say that the Northeast is going to see the highest departures relative to normal, I think the pattern may favor too much ridging over the Rockies for the Midwest/Plains and the southern branch may not be active enough for the MA, Srn Plains, or TN Valley.

At least 76-77 was very cold.

1976-77 was a weak nino...The highest oni index was 0.8 for the ONDJ period...there are five other weak el nino's below 1.0 on the new oni index scale...assuming we will see a weak el nino 1976-77 was the only one coming off a la nina...

year.....OND...NDJ...DJF...JFM...

1953-54...0.8...0.7...0.7...0.5...

1958-59...0.5...0.6...0.6...0.6...

1969-70...0.9...0.8...0.6...0.4...

1976-77...0.8...0.8...0.6...0.6...

1977-78...0.8...0.8...0.7...0.5...

2004-05...0.7...0.7...0.6...0.4...

all six had a cold January...

04-05 was weaker than 02-03, more like what we'll probably see this year.

Perhaps in pure ENSO strength it could be similar. I just think prior years have some influence as well not to mention the many other key teleconnectors that are out there to compare.

Definitely...my top analogs are 51-52, 68-69, 69-70, 76-77, and 04-05....Niños like 02-03 and 09-10 are probably too strong and too west-based to fit into the analog package, although 09-10 did follow a double Niña which may have some forcing on global temperatures. I am looking more at the east-based events like 51-52, 69-70, 76-77 which tend to offer some cold weather but not as snowy, although it's certainly possible it shifts west as time goes on. It's also possible the Niño continues to strengthen as 09-10 was also a late bloomer in that respect.

This is my thinking as well. I wonder how active the sun was in 51-52, 69-70 and 76-77. I am thinking that even though the sun has become more active recently that the Sun is still very inactive when compared to those particular analogs that match the ENSO state we are entering.
