Think the index can get down to -5? Is that the lowest it's gotten in a long time?

Wow the last third of December is MUCH worse than even the first third of the month!

The increase in big precip events (both rain and snow) is very noticeable.

It's noticeable in urban areas where it's become much harder to get a big event in March

But also much bigger snowfalls, I'll take that trade off

the early 00s were notable for big December snowfalls though

it's not the same as before though, the cold AMO phase in the 80s featured much colder northern Atlantic SSTs.

Triple phasers can track further east....there was one in 2004 or 2005 I think it was that hit Nova Scotia really hard. One could argue that the tracks of triple phasers have been moving east with time if you track the historical progression of their storm tracks.

Sounds like you think the possibility of a BM track triple phaser has increased with climate change, maybe this is why you think we still have a chance to one day break our all time snowfall records.

Would love the CMC to score the win. Based on the "downgrade" of the GFS might mean that the CMC moves ahead of the GFS for accuracy.

what's the record overall and for the month of December and for winter? Looks like it's approaching -5 on that graphic!

We really just need two nice wintry months to have a very good winter. 1977-78 was basically a two month snowy winter 2010-11 was a two month snowy winter 2014-15 was a two month snowy winter too

I wonder if there is a way to track of the signals these indices have been provided have slowly warmed over time I can see our Januarys are definitely warmer than they were in the 80s, when they averaged in the 20s the majority of the time.

0.T?

where do you find this stuff lol and what are they carrying? are those midget St Bernards going to rescue people?

But wasn't the 13th always the target date? Somewhere around that date was always supposed to be the first realistic possibility at snow.

well when we actually have important storms the weather moves from south to north or southwest to northeast. when storms are weak it moves from west to east-- that's a boring zonal pattern. North America is a puny continent, consider Asia, where no one ever talks about the influence of the Atlantic on their pattern, even though that is the Ocean to their west.

the "warming" of the -nao/-ao signal over time shows the impact of climate change moreso than the importance of the Pacific (also the Pacific is changing because of climate change.)

Reagan inauguration day in Jan 1985 was the coldest day I've ever experienced. No snow on the ground of course, which made it even more amazing that it went below zero in the morning and only reached single digits for the high in NYC (the only time in my memory that's happened here.) The theme of the 80s was mostly suppression events with cold and dry in January with the few outlying storms I mentioned above, and then it warmed up rapidly in February and the cold and dry was replaced with rainy and mild.

Unfortunately that's often too late for urban areas.

Yep, it created a nice suppressed pattern all the way up to DC where areas near there and south of there actually had real winters. I don't remember March 1980, but January 1982 was pretty big here, that one caused the downing of a jet in the Potomac if I remember correctly? Later, in April, we had a historic blizzard, that may be the only time I'll ever get to see that. February of 1989 was a blown call for us, as cold and dry air kept that storm south of us and ACY got 19 inches! December 1989 was another one....this time the storm was too close to the coast and we changed to rain with less than 1" of snow on the front end-- both were predicted to be 6-8 inches here. Do you remember the Veternas Day storm in 1987, and did you get anything from that? We only got 1-3 inches here, but that storm hit much harder both south and northeast of here. Jan 1987 was big here too, I think the biggest storm since the Feb 1983 historic 2 ft blizzard. Later, we had accumulating 2-4" snow after the middle of April which is almost unheard of here! Back to back Aprils with snowstorms!

That was a superclipper. I think the Millenium Storm was one of those too?

That became a more recent phenomenon, back in the 80s they were more likely to give a light to moderate snowfall. The last winter we had that kind of pattern that I can remember was 08-09.....remember that pattern (before the March 09 coastal)....it was cold with frequent light snowfalls. Nice wintry feel, an overperformer of a winter.

We had them at least once a month back in the 80s....they were good for 2-4 or even 3-5 inches sometimes.

There was a snowstorm in November too, and since we didn't get that if you subtract that from the totals, most of us are below average snowfall.
