Even snowing harder than expected way up this way. Only an inch but we should be able to pull 3" when models had just clouds as of 18z yesterday. That band is much further north than expected it seems... even north of ALB.

That’s as classic a radar as it gets. Widespread 20-40” in that arc starting in PA and going ENE.

That’s the craziest nor’easter obs i think I’ve ever seen at those temps.

My sister near the BGM airport is getting crushed. Can’t wait to see the pics. 0.75” water in 2 hours. (0.40” and 0.35” in consecutive hours now).

ORH wind increasing pretty decently... ENE at 10G20mph. That's a classic flow. Just favorable obs all over the hit zones.

BGM with 0.21" water in the bucket over the past hour... at 18F degrees! That is an impressive cold column QPF dump.

This is as healthy as it gets for banding... Central PA. State College area. Has to be widespread 2-3"/hr. Maybe 4"/hr in the heaviest sustained echoes? That is an incredible signal.

I feel like it can be a security blanket though. Even if mid-level subsidence arises, you at least can maintain on low level lift but maybe that's more true for the NNE mountains. But yeah, the jackpots don't have to be the higher terrain in a system with strong mid-levels... the valleys are fair game. I just think of a spot like the Catskills that may jack with mid-levels and orographics... 4,000ft is 4,000ft. That's a lot of prominence from the Hudson Valley on ENE flow to begin with. That Eastern Catskill zone can rack up some ridiculous totals.

Sounds fun in PA. PAZ017-024-033-170130- Somerset PA-Clearfield PA-Cambria PA- 729 PM EST Wed Dec 16 2020 ...A BAND OF HEAVY SNOW WILL AFFECT SOMERSET...CLEARFIELD...AND CAMBRIA COUNTIES... HAZARDS...A slow-moving band of heavy snow which can rapidly reduce visibility to near zero. The snow intensity is extremely high and thunder has occurring close to Johnstown.

The Berkshire areas of Jiminy, Catamount and B-East should be awesome. I think everyone has a shot at 18”. They'll have much more natural snow than General Stark, Mansfield, or Jay for sure...which is always worth reveling in the backyard bounty.

Thanks for that man! I didn't know that's where Mittersill was... or at least never thought about it, figured it was all Cannon. Good info. I love trying to push the boundaries of a camera and seeing how far you can see. The winter arctic air views from the summits in lower angle light can go forever. Can see 80-100 miles away easy.

My sister's near BGM. She's at about 1,000ft there. That snow growth bodes well upstream into SNE/CNE.

So not 3-6” lol.

It’s a 10:1 snow map. The 12-18” forecast isn’t made at 10:1. We all know this .

It takes a lot to excite you doesn't it? lol. Widespread 8-16"... local amounts to 16+ gets a "meh" then you are in the wrong hobby for the northeastern US.

Yeah I've had my share of 600mb bands, lol. I always look at those Coolwx graphics for the slice of atmosphere vs. time to see where the lift and DGZ is. I do like the visualization and evolution of those 600-800mb fronto maps... shows how this event should play out pretty well. There's a wall that comes in over everyone in the SNE forum and then pivots across that interior zone the GFS has the max QPF over. Overall a big storm for the heartland of the Northeast. Not going to lie, I definitely should've traveled down to my parent's house for this one... I think they'll get croaked. That area has had a decent run of it in recent years... they had like 26" from the early December event last winter too.

Ahh makes sense, I figured the average of 600-800mb would capture some deviation (like using an average thickness of a slice of atmosphere) but you're right if it's higher up at 500-600mb that makes sense. Thanks though, great learning experience.

Just crushed. That's a lot of QPF in a very short period of time. You guys are going to make up for lost time so far. Excellent banding signal.

Very Jelly of my hometown just SW of Albany... 18z GFS with a sick panel for that band from BGM-ALB-RT 2 in MA. It even has a spot of 1.20" in 6 hours near the intersection of Albany County with Columbia County. Those are crippling snow rates. Hippy gets crushed.

18z NBM/National Blend of Models has that very clearly on the simulated radar. It goes from NE PA through ALB/Just South and through NW MA/SVT and into NH.

I've always done the same thing. Dendrite cleared me up last night on that too. I didn't know the best actual band was NW of the best fronto... I just assumed the models missed it by a few miles, ha.

Good luck AMWX SNE crew... plenty of photos please!

Was pushing the camera lens again this morning.... but above the inversion the visibility was insane. Could see from Maine to Quebec and New Hampshire from Mt Mansfield. I had never in 15 years noticed the trails on Cannon Mountain being visible from Stowe but could make out the top trails with the naked eye. The photo is a bit "noisy" but you can see the trails on Cannon with Lafayette behind it.

GFS

Lines up well with Reginald.
