All snow here in this part of the valley as well. Maybe another half inch almost. Seems likely to slot here soon, maybe we get a few more snsh later on again before the system finally pulls away

Yeah it's ugly. Raining fairly heavily now, 32 degrees. Higher terrain could get bad.

I think it has more promise for short term advection based nowcasting algorithms. Google has code in github you can run. IMO it's still not as good as DFT based approaches but closer and could eventually be an improvement. At some point it may be able to somewhat resolve CI based on implied OFB positions. A DFT based alg won't be able to do that.

It's been awful with cyclogenesis this year. Next time you read a magazine article pimping how AI based models will soon be better than physics based models, take the believe it when you see it approach.

I like the 1-2 line summary record keeping and do the same. Here's mine: 24/25 37.5" 12/5 7.5" Strong clipper, surface low dropping through ON/QC, cold air in place, s/sw flow jacked here to Kev. Sticky, trees caked. Overperformer. 12/8 .5" Weak clipper, not much moisture. Forcing mostly north. 2-4" higher terrain 12/16 .5" NE fringe of a deamplifying wave bringing WAA snows and drizzle further south. 12/20 1" Ocean storm trending west, incoming clipper, fluffy sn- all day. 4-8" near Boston, 3-6" ENY 12/24 1" Trailing cold front from clipper moving north of here. Dry, dense snow. Small flakes. White Xmas 1/2 2" Lake Ontario narrow streamer lined up perfectly. SN++, light, convective. Lucked out 1/11 3.5" Northern stream s/w with unphased ocean storm ots. Very fluffy, moderate snow all morning. 1/19 4" Wave forming on arctic front behind initial -rn storm. Quick hit, very fluffy. 1/30 1" very light, southern edge of a clipper precip shield. Periodic snsh afterwards and wind. 4-6" N Berks. 2/3 2.5" dense. Fast moving clipper, cold air in place. Widespread 2-4" across SNE 2/6 1.75" dense. Quick hit, weak swfe. Mostly sn but bad growth. Cold, bad radar. 2/9 4.5". 3" dense from WAA, 1.5" fluff. Mod bust, MA in subby zone. Fast mover, 2ndary shot east, snow in VT. 2/10 .25" persistent backbuilding mid morning snsh on weak CAA 2/13 .5" front end of a weak and warm swfe. Followed by ice and some rain. Net loss 2/16 6" 2 day event, sn->ip->zl->rn->sn+. Long duration, complex SWFE w/backside snow. Glacial with fluff top. 3/13 1" narrow w->e convergence band left a stripe of snow across parts of W and C MA

Nice, thanks. FWIW I have 30" here very near where you show 21" just SW of Quabbin.

I've noticed over the years that the nam occasionally has weird precip issues that look to be more of a software bug than valid output, albeit with its own caveats. If look at all the other model parameters there they aren't discontinuous run to run in the same way that precip is.

We've checked off the remember when we used to get clippers and remember when we used to get nickel and dime events this year. Maybe in March or next year we bowl.

persistent backbuilding snsh at the moment

Ripping pretty good along i91 atm

3" on the nose, dense. Squeaked out advy criteria at least.

Take em down I think.

The slot is killing my virga lol

RGEM coup incoming?

Yeah, it should be 100% or nearly so. Stuff that hasn't been skiable in 2 years. Happy for them. Hope they get a nice big crowd willing to human groom the woods in for the weekday morning crew

I'd rather positive bust an advy then negative bust a warning. 3-6" here final call. Moving quick, meso QPF red flags, less than 10:1 with lift not ideally aligned with the DGZ, maybe some downsloping on easterly flow. 3-6" cake flour is a great event regardless IMO, but selling bigger totals here IMBY right now.

Just 21 here, but 27/28 on the hilltops nearby.

1.75" dense Maybe 3 or 3.5" at the Beast earlier when I left. Reporting 4" now.

Now this is awesome

good on trail at any rate. They might find themselves hopefully on the right side of this N->S gradient for the system tomorrow, and could use a heavy stick to your bones snow to get the natural stuff open. Yesterday was great, but the snow was too fluffy to venture onto that stuff. Maybe more on Sunday too.

Definitely the big cold departure days, 21st to 23rd yeah. But the first half of the month was super windy out here and we weren't radiating very well at all. 27 high 22 low type days with no precip. The real feel was more BN than the actual, at least for a while. Less the 2nd half, but even the last 3 nights have been breezy.

A good decoding explanation here: http://www.theweatherprediction.com/models/fous/

local coops, with records that go back pretty far, were ~ -1 for Dec and will be ~ -1 for Jan. We take.

Great morning at the Beast. Been waiting for this one. 4-5" of blower on top of smooth hardpack. Super fast, super fun. And where they groomed was amazing too, cord so soft and poppy it would bounce you out of turns like a trampoline.

FFD or bust. RFD was very meh.
