I didn’t hate that run…decent overrunning potential shown there even if it didn’t crush us verbatim on that run.

NAM keeps interior in the 30s. Maybe near 40F at the peak. But it torches SE of a BOS-IJD line.

On that map I’d say the risk is fairly low. PV is pretty far southeast and heights out west aren’t that low. Prior to that though, the risk is higher with lower heights out west….so 1/30-2/1 could be a cutter but it could also be a a snowier solution depending on all the shortwave nuances we can’t predict yet.

Yeah HRRR and RGEM were more like 2-4” (maybe a little higher up by you)….There’s some synoptic stuff I don’t love about this one if we’re trying to slam 4-6” in 6-8 hours. Usually want to see a nice broad area of isentropic lift well out ahead and it’s kind of meh…NAM does try for a narrower area and it’s fairly intense, but I hate relying on a thin band. A little shift east or slight increase I confluence would probably do wonders.

GFS still pretty weak with the thump down here. I’m leaning toward that solution and not really buying the large NAM amounts. There’s just not a lot of vort energy that curls up into us until later when we’re already too warm for snow…and even when that happens, it’s strung out vort energy. Of we get a slight bump east or a slight increase in confluence, that could change but for now I’m leaning in the 1-3” range.

That was a nightmare month up there. I remember Scooter had like 15” from one of the storms and you were posting a crust of like 2” glacier that had refrozen after a massive cutter. The silver lining was that it didn’t last into February. Pattern flipped and NNE got annihilated the rest of the winter. Went up to Sunday River around the equinox in March that year and they must’ve had 45”+ on the level where we were staying. Up at the mountain it was even more than that.

Yeah it’s one of those classic gradient looks where it could be quite prolific if nuances/areas of confluence break right for us…and if they don’t, it could be a real 1980s pattern with cutter and then arctic cold shots behind them.

Def overperformed over a large area. Not a lot of models had widespread 12-18” amounts over CNE…even the weenie clown maps. A few RGEM runs had around 12-14” but even that wasn’t high enough in many spots up there.

NAM still looks quite thumpy down here. HRRR was pretty meh this run.

Yeah prob run into the WAA band on the way down.

GFS still not biting on the NAM/HRRR optimism. Pretty weak sauce on the thump. Bit of a model battle.

00z NAM is quite a thump too

I’m gonna call it 5.3” here. Great over achiever. Actually the event total would be more like 6” but the rest was from last night before the rain.

Took a few pics when out shoveling

Jet streaks FTW too. That powerful exit region worked some magic and prob turned this from mundane 1-2” to lots of 3-6” amounts.

53.6 last year at ORH. Not quite a ratter but not good.

Nearly 5”…should eclipse it if we haven’t already as this was about 10 min ago

Last bands coming through. Snow growth actually still pretty decent in this

Hoping to crack 5”. At 4.5 now

Funny I posted that and literally liken5 min later we are pounding perfect dendrites again. Awesome snow growth…must be a deeper area of lift punching the DGZ in this band here.

Snow growth isn't pristine like it was in that first monster band, but vis is down again and it "Feels" like a snowstorm in this stuff.

Nice you got over 3.5”. Might be able to nudge it up to 4” with that last band rotating down.

I doubt it trends much…it’s been amazingly consistent for days (I know Tip posted something similar). But small nuances could help…if we can get just a little more vort energy on the eastern flank of that trough, it would really help that WCB be more intense and perhaps also nudge the secondary reflection a little deeper which would lock in lower level cold more efficiently. We’re not talking drastic changes but it could be like the difference between 2” and then rain with temps getting to 40-43F in a place like Bedford versus 5” and temps never really getting above 35F.

Steadier snow has resumed. Not as heavy as that first band though

There’s almost two different WAA precip batches…the first initial one is pretty good from like N NJ to S CT and it’s weakening as it lifts north from there and then another reorganizes about 8 hours later but by that point, we’re starting to warm aloft so that batch is mainly for N of MA/NH border. We got caught in between….hopefully that doesn’t happen but some models have shown that. 18z NAM actually got us decent with the initial band. Didn’t weaken it as fast.
