Maybe an XMACIS glitch since it’s now back down to 2.9”. Very similar to LGA.

There are 16 days left with a volatile pattern evolving. Way way to early to throw in the snow towel for this month.Way way too much cold around. The junkies don't see their next fix and are jonesin hours after the last flake fell. This place is bonkers

Yes, I think we will avoid getting shut out next few weeks...couple that with improving climo and the next few weeks will probably still be snowier than the last few.

Great calls! Ryan had a great forecast for CT too.

18.1

Low of 11 and currently 12.

That’s definitely possible. Would need a front ender or else we’re rear ender.

Definitely a D- or an F on my forecast for this. I also try to factor in the backend/reasoning to the forecast into the verification and weigh that much more than the outcome itself. For example, if I did a forecast somewhere of 3-5" and said that would come on the front end of a storm, and it turned out that happened on the back end with a CCB...well that would grade extremely low, but the reasoning was incorrect. The most incorrect aspect of my thinking here was a stronger band developing and impacting Long Island would cut back on totals farther north across CT (subsidence) but that did not happen. While I don't know what everything looked outside Saturday night in terms of snow growth and flake size, it was clear there was just enough lift, combined with a deeper DGZ, to utilize better ratios. I definitely underplayed that component. In terms of assessment, I don't think I would do anything different if I had to do this over. But what I would do is certainly go a bit more "aggressive" (putting aggressive in quotes because we were really dealing with 1.5-2.5") and maybe do a range of 1-3" over a larger area to cover uncertainty better. Or maybe even C-2" but that's a range I hate.

I know you are into that, but I don't give a rat's ass about the negative departure if it doesn't snow.

Pacific upwelling much faster at the equator than scientists thought “It turns out that equatorial upwelling in the Pacific is about 10 times faster than we previously thought,” Karnauskas said. “And this could be really important because that water rising toward the surface in the Pacific covers a huge fraction of the ocean surface, and it affects things like temperature and nutrients needed for photosynthesis.” His work, published today in the Journal of Climate, reveals the faster rate of upwelling and determines why older estimates were off. Karnauskas combed through old observations and analyzed vast amounts of new data from state-of-the-art measurement tools to get a more accurate estimate. The findings point to a key discrepancy in global climate models, which currently predict significant warming along the equator in the Pacific. This new rate may help researchers understand why they have struggled to capture key climate trends in the region. https://cires.colorado.edu/news/pacific-upwelling-much-faster-equator-scientists-thought https://journals.ametsoc.org/view/journals/clim/38/16/JCLI-D-24-0704.1.xml

Would still need some improvements but doesn't seem like much in order to get some front end snow on a couple of these systems traversing down from the Lakes through New England. Obviously we want to see some shifts but we are still 7-10 days out from the next period of interest. This is not a big storm pattern that's for sure

Yeah about 2” here. Bent over again. But cheer up, Mansfield stake at an all time high. Boing!

Yea just ignore the ensembles. 2 days ave above normal and snow is possible. Month will finish some -7 -8 here

Interesting inversion. One of the quickest cold shots I can remember

12/5: 1.3" 12/14: 1.8" T: 3.1"

Final total from Rainthuen- .8

12 here.

Low of 15. Deep winter feel. Even in good winters we don’t get many days like yesterday and today.

Didn't the 1 inch record continue because Central Park said there was .9 in one of the snowfalls?

Maybe snowpack? Otherwise odd to me.

I totally buy it...man, like exactly the PT pattern that I expected to develop around the holiday and well in January. I think the next window opens in mid January (ducks and runs) I can not believe that I am coming out of this pattern with 3.75"...less than NH and the cape....just unbelievable. We should get some shots at front enders and SWFE given Canada shouldn't torch, but my god...

As things stand right now it looks like at least the next 8-10 days go by the wayside....

Looks like it's completely in the center. That's a bullseye if we're playing darts.

12/14: 1.5"
