Little ocean effect out by Chatham right now?

Nice looking band! edit: appears as though I linked a dynamic radar that is updating. The band doesn’t look as nice now due to beam blockage

Heard some reports that Jay Peak was a bit wind affected following the squalls on Thursday. That fierce northwest flow deposited a ton of snow downwind into what is usually the deepest locale in New England. I was confident depths would be good, and a thorough exploration on Saturday found conditions that exceeded my expectations. The whole zone is wide open for the taking, though some danger still lurks with a smattering of open drainages poking through. Up high, tight tunnels transition into spacious gladed gullies choked with powder. Bushwacking and bootpacking into a zone famous for it's felonious past yielded a skied off chowder experience. When the forest closes back in on the scar, prior traffic disappears into an extensive menu of deep lines that open up among powder plastered conifers and hardwoods. I've never been to Japan, but I imagine this is as close as the East Coast can get visually. Hard to believe it was December 6th South of I-89 it is a different world. MRG managed to get the single going, but rock skis are an absolute necessity. If you're willing to take a few shots to your skis, conditions were actually pretty ripper up high with tons of funky low tide features. Chute was especially sporty, with a double (or triple) drop that was teed up right under the lift.

MRG opening Saturday with the Double and P-slope… though the Single has been spinning on the webcam so we may get some additional terrain added

St Johnsbury is somehow the current accumulation leader in New England with 8.6". I don't think a single model had anything close to that outcome

Models can't initialize this storm to save their life. The hrrr is completely missing the big band over Northern Vermont. Pretty garbage model performance all around, from the medium to short terms

I don't know if there's any actual significant correlation between these two variables, but it seems like you need a deep and rapidly intensifying low pressure in order to have a successful backend "flash over". Mbs in the 990s, tilted mid levels, and rapid forward progression just won't cut it. Kind of a weird SWFE hybrid rather than a true coastal. Big warm nose etc... If you can't stack the lows, the dynamics just aren't as good for the development of a cold conveyor belt

Yes, or just south of you

Sorry for a bit of mesoscale PBP, but yeah, it's coming. 850mb banding is about to start cranking, huge fronto uptick over the Southern Hudson Valley

Very impressive band over Albany right now, this is likely more associated with the cyclone starting to get it's act together rather than the WAA forcing we've seen to this point

Should fill in as the cyclone gets going... rapidly too. There's a good slug of dynamics lined up that will only improve as it approaches

850mb fronto really starting to kick into gear upstream as H8 works to close itself off. Heavy rates are likely to develop along the coastal front soon. Central New England still doing nicely under some respectable H7 fronto delivering steady moderate snow

Light rain showers in South End, Boston

Deformation band showing up right over BTV and into Mansfield. Take the over for the Spine?

H7 fronto is fueling this banding in the WAA. Once the 850mb low begins closing off this afternoon, banding will shift closer to the surface low

The jack should be where the WAA portion of the storm is maximized, and the banding this afternoon overlaps the most. I think the deformation is gonna come in a bit NW of modeling, seems like the atmosphere has it’s preferred deform location across Central NH based off prior events (aka congrats Dendrite)

Looks like BTV will be ticking up totals for Thursday along the spine if that modeling holds

This includes the squalls on Thursday

Dual lows still on NAM. Really having trouble pulling off a coherent cyclone in the fast flow

If the band orients WSW-ENE through you and Dendrite, would have to think the summit of Kearsarge could be our jack

Gotta think a lot of the bigger terrain available off 242 might be in play by now…and I’m not talking about The Dip. @bwt3650 you hearing any rumors? Hypothetically of course

It's going to take a significant resolution upgrade in order for the AI models to make the jump. Outputs look smoothed, especially at long range

Pretty bad medium range fumble by the Euro-AI. A bit more concerning was just how long and arduous the cave back towards the globals was. Once outputs began to trend, corrections were steady and incremental but far too slow for me to take runs seriously for several days. Model outputs aren't very useful if it's obvious they're playing catch up. The AI Models as they currently stand are a great new tool, but I don't think they're ready to compete with the globals... yet. I guess I currently treat them akin to the Canadian, maybe a tick below. However, I think that in a couple years we may have significant disruption of the current model heirarchy.

Dual lows showing up for both EURO and GFS. Couple more cycles of that and I’d be inclined to say that’s a real feature. Nonetheless, cyclogenesis seems to be going to shit

Looks like amounts really dropped off south of I-89. Judging from webcams, probably 1-2 windblown inches at MRG/Sugarbush
