Can always squeeze out a nighttime event in between periods of warmth

Yeah wavelengths shorten and bowling ball systems can occur, however overall pattern sub par.

At least DC and Baltimore have a legit shot at average annual snowfall with the next statem.

I thought we had like one inch in April?

But in the middle of March it was amazingly warm (mid to upper 80s with sunshine!)

 

yeah april was minor. May have been more significant to the south with of course the major mid month warmth that wasn't expected. I believe my forecast was 72 and we hit 85

It's probably why mild winters tend to stay mild even when the pattern becomes "better" later in the season.

You usually need that December snow and cold to make sure it comes back after any thaw later in the winter.

 

Definitely a big takeaway...mild/snowless winters don't usually turn cold/snowy.   (exceptions like 06-07 do exist)   So had to be skeptical of calls of a big pattern from mid Feb to mid March-in reality it will be a window of about 10-12 days like the one in January.

The AMOC shutting down abruptly would wildly disrupt monsoon cycles and lead to major agricultural failure. Whatever the actual acute temperature impacts on North America (lesser) and Europe (greater), it would be a catastrophe for many other reasons. 

There was a concerning paper last year stating collapse could occur between 2025 and 2090 which is considerably sped up from timelines running on older data. Doesn’t mean they’re inherently correct, but it’s concerning (IMHO). 

Yeah sooner rather than later is happening:

Yeah, cold and snow cover, makes more cold and snow cover. Kind of how snow ball earth was a runaway feedback cycle to cold. You have record low snow cover over our cold air source region. That’s going to increase solar absorption. We are lucky we even made it to double digits snowfall wise. This could easily have been 97/98 up in till now (.5” cpk)

2015-2016 was the real outlier. All the rest of the Decembers with under 1” of snow since 1950 had below average seasonal snow in NYC. This season is continuing that pattern.

Did we have snow December of 2014?

Yep. This one is following the strong Nino climo of warmth early-mid March warmup

 

Ultimately ensembles did okay...we got the window 2/12-2/25 we thought we'd get and we might see 3 snow events out of it in the end if something latter next week works out.. the rule this winter was no pattern held for more than 10-14 days really and I expect the same happens again...the pattern 3/10-3/30 probably won't look anything like the one from 2/26-3/10 will.

so this weekend's storm is probably the last snowstorm of the winter?

Considering that there is no background cold or high pressure confluence in southeast Canada to prevent systems from cutting, I would argue yes. And every passing day, the average temperature becomes warmer and it’s harder to snow. With no cold air in the mix and minimal snowpack, it becomes even harder. What’s worse is that high latitude blocking has all but disappeared from guidance, indicating a very warm March coming. I think it’s safe to say this is it for the season. Sometimes the easiest path is the right path, and for this winter, persistence forecasting was key.

We done after Saturday 

Eh, no one really knows. (See this past week)

The only thing that changes are probabilities. I’ve seen enough nice, early springs interrupted by nonsense. (April 1990 snow, March 1998 and 1999 snow, etc.)

Sure, it’s unlikely, but you never know.

and who knows how different the winter would have been with more sustained snowcover to our north as well as more ice cover on the great lakes.

Historic low for Great Lakes ice in mid-February.

I'm glad I'm not the only one who remembers these lol.

I think we had a 2 incher in April 2000 also, people tend to forget these events.

We also had an event in April 2006 that is mostly remembered for adding the 0.1 that NYC needed to get to 40.0 on the season.  What they don't remember is how heavy the snow was and down here on the south shore, it added up to about 2 inches of snow in 2 hours in the middle of the day. From Brooklyn on east the snowfall rates with this storm were more impressive here than what we got with the so-called February 2006 "HECS"

Admittedly, getting at least three 2 inch events in this winter with snow cover lasting for a week on two different occasions would raise this winter to a C-.  We can't expect 30 inches every winter, or even 20 inches unfortunately.

If there was only one event in this winter of 2-4 inches it would still be a failure.  But getting possibly three such events makes it tolerable.

Big part of the reason cold was lacking this year....

Snow cover is important, but I think the effect of lake water temperatures or lake ice on the temperatures in downstate NY is less than some here seem to think.  If you live on the south shore of Lake Erie, then it is significant.
