ORH_wxman

I think the key is probably the DGZ lift. My guess is the best DGZ lift stayed near 495 and westward for most of the storm. It also coincided with the higher terrain so we saw a bigger elevation gradient than usual. But even a lot of 495 belt with modest elevation in the Littleton to Berlin to Hopkinton/Holliston zone saw 4-6”...it was kind of telling to me that once you got further east on 495 like over to Lowell and Lawrence that they really struggled and I’m wondering if the longitude there hurt with worse DGZ lift.

Phineas prob has 16-18? Could be more...Alex in the other side of the mountains looked like he did pretty well too though prob a bit less. Our N ORH county posters had 10-12...I measured just shy of 10” on winter hill on the north side of ORH. Back in Holliston we had about 4 inches of the densest/wettest snow I’ve seen. Randy/Zwyts chasing in eustis Maine prob had over a foot.

That was also a ridiculous cutter. It basically stalled up in Ontario. Pretty unique. When you have tropical dewpoints into northern Maine, there’s no escaping those cutters.

Yeah that is snowpack country there eastward into Maine because of the big CAD they get. The torches they get are usually brief, even in most cutters.

Yeah I was mostly commenting that the map got it right but prob not due to an exceptional skill there...it was wrong further southwest...even excluding elevated places like ORH (say, the 495 belt from maybe Berlin/Bolton down to Milford had solid advisory level snows 3-6” when the map was spitting out like an inch) But it was definitely far more accurate than the other clown maps which we knew would be too optimistic in this airmass. You're still going to defeat that map in the long run looking at soundings and analyzing the model.

Yeah I don’t think anyone would have forecasted 2” there based on the data we saw. Same reason I didn’t buy the 3-4” amounts it was spitting out for ORH. I figured at least 4-5” minimum for you (like what many got further south of you in the 495 belt). One of those weird events...I’m wondering if the longitude there hurt with the lift placement not being as much in the DGZ. Would be interesting to go back and look when this is over.

Ahh yes those piles were prob from the 3/4/19 storm. That was the best storm that winter. Dumped a widespread 8-16” for the eastern 2/3rds of SNE.

My guess is they had about 5 or 6 inches. Not too bad but I would’ve thought more of you asked me this morning when it was flipping pretty early.

When everyone was flipping to snow ahead of schedule I thought it was going to be a positive bust...LOL. Shows how quickly things can change. I was sure that the 128 belt was gonna get rocked. They were changing over around 2pm and it looked excellent for hours...but they just never mustered the intensity after the flip. The low level temps were a problem but I’m still surprised. I guess maybe the lift wasn’t quite lining up perfectly in DGZ which really helps in marginal setups. You need everything to go right...esp at lower elevations and perhaps that was the one ingredient missing in an otherwise perfect opportunity to overcome the marginal near-sfc layer.

Yep, 900+ feet in ORH. Paxton just west of ORH just reported 12.5”...they are up near 1200 feet.

Yeah I was wondering if the airport was running a degree warm or so. Several of the other mesosites around there got to 32 as well.

It’s so-so. Today’s storm really messes up an otherwise great setup for Dec 7-8. We’ll see about 12/13ish...that could cut or it could end up ok...but will depend on nuances. Today’s guidance wants to lean cutter. Hopefully we get another chance behind that but a lot of uncertainty.

Here Walt, I measured this about an hour ago

I am a bit surprised we didn’t see thunder snow in more spots. I agree with Scott that a little more antecedent airmass would have helped tighten up that ML Fronto. Then again, like Tip said, with a colder airmass oozing in, this storm is probably hitting the Grand Banks instead, lol.

He said he lost power quite a while ago.

Metrowest band incoming. Ray, you are probably finally ripping pretty good.

YEah that looked really weird and the snow intensity didn’t respond by ramping down. So I was suspicious as well.

Very aesthetically pleasing radar...classic looking storm

Yellows are starting to shrink a bit as the R/S lime becomes more defined (as Chris opined above) You can still see the ML forcing back into ORH county up into Hillsborough county NH and it’s going to go nuts for metrowest here

R/S line is hanging out just outside of BOS

There’s a feedback there too in addition to what you said. The harder it snows, the closer to 32F the lowest layer gets from latent cooling...and when the intensity slackens a bit it goes back to like 33-34F.

Ha, you got me, it was windy.

Go north on 495
