January 26-27 Snowstorm Disco V

The RAOB missing in a key area from the NAM makes me suspicious of it.

That said the Euro did come a long way off it's solution of a big wrapped up storm. It's now like all the others in having a semi-split shield and it takes longer to wrap up.

What if the meso's aren't having feedback issues but are instead picking up on what will be intense banding that limits the NW extent of precip?

No it didn't . It adjusted and made some relatively small changes. No one will likely get 20 but per Euro many get 12+.

You are really reaching. We should say the NAM really caved too in favor of the Euro since it came NW from its whiff at 06z.

yeah the NAM was a huge whiff, lol....its been atrocious IMO with this event.

but i guess its just the usual waffling and arrival at concensus.

ensembles have been great, and I'm really starting to learn this winter from you, why you should use them........

You really think they are going to get this much?? That would be nice..

Well to be exact they need 11.8''...I went 8-14'' for the area but not sure if we will get more than 10-11''. If this thing tracks any more east than modeled we can easily forget that.

I think we should be good for at least 6-8''.

Ya thats my guess also.. Probably more towards the 6 side..

Love the spread...

Not criticizing any professional forecasters by any means, quite the opposite... this is an extremely difficult scenario and I have all the respect for those who have to put their money down on a solution. Just a reflection of the difficulty here. We are within 24 hr frame.

You said last night you felt the idea of the moisture running out ahead of the support was wrong/that the split idea was wrong. The euro doesn't wrap up like it did, as early as it did. It just came off the idea of pounding far western areas with another epic storm. Who cares what the NAM did, I think everyone has put it on the burner until it's not missing critical data.

Why don't you post the 700 RH maps (or if Scott has them so we can overlay) from last night versus todays run, and the QPF totals from selected points like Albany, southern Vermont, NW CT, western MA, west/southwest NH? It's changed how it's handling the system. Wrapping up later was a premise of all the other models coming into the 12z today.

It's a two part storm on the Euro, or closer to it. That's not a minor change SW of us.

There's no sense fighting over it, I don't think we're done with that change. We can pick up the merits at a later time.

Why is Barry going so much lower than most?

How is it a 2 part storm???????? it comes in with a bang around 36 hours and dumps through 48 and tapers off to 54. Typical big storm. I'm perplexed how you are getting this from the Euro?

I've said the whole time I don't think its fragmented by the time it reaches us, I'm not talking about well S of here.

But at any rate, I'm not going to get into one of these obscene 2 pages debates with you over semantics that has little affect on the sensible wx forecast. Bottom line is most guidance is much closer to the Euro than the mesoscale models.

I don't think anyone was forecasting 2 feet of snow despite the uber wrapped Euro solution. I have said I believe the Euro was closer to reality than the mesoscales, and I'm sticking with that. You can believe what you want or how some model is moving a little vortmax in the gulf of mexico the wrong direction but its "still a great storm for most us"...I'm mostly interested in 3 things: timing, duration, and snow totals.

To get those 3 things, I'm focusing on the track of the upper level low.

SW Jerry, No model shows a two part storm...you know what I mean. Instead of the initial pulse getting entrained into the entire system it's ending up a little east. So when the entire thing WRAPS UP LATER (YOUR WORDS), it's not able to produce as much snow as it was earlier as far west. The CCB gets ripping, we get our snow, the kicker comes in and closes the door.

I'm done fighting over it, the Euro didn't hold serve, tick west, or anything else but move east, and shift the dynamics ESE in far western areas.

It moved towards consensus as everything moved towards it.

The speed of this storm will make it tough for huge amounts...we saw most guidance slower the previous 2 days, but its really hauling.

One of these days we will get a nice, long duration event. Most of what we have seen this winter have been fairly quick.

I long for a CCB that just parks its snowy but overhead for 48 hours

We thought it would trim back qpf a bit and move a hair se..it did. The NAM will probably come nw again at 18z. My guess is the GFS will too. This is what sometimes happens when models have different solutions. A compromise. The question is....how weighted is the compromise?? Is it more to the GFS/NAM or Euro? I just don't see how one caved to the other. You can pick apart any change on a model and make it the principle of your argument. I think we are stabilizing overall, but I think the NAM and GFS may tick a little nw at 18z. As far as the euro goes, maybe it moves 10 miles se at 00z..I dunno, but I would not be shocked if it holds steadfast overall. That's some nice convection in the GOM.

Edit: I meant would not be shocked.

That's a nice, out of context/never spoken shot you threw in bravo as a moderator. Way to play by the rules of attacking the idea but not the poster.

Well the Euro shifted east a fair amount from its days 6-7 progs to around day 4. Obviously it's earlier hugger or inland runner scenario didn't work out. SYR won't be under 18" of snow on Thursday morning. ;) But it has been pretty stable over the past few days.

No it didn't . It adjusted and made some relatively small changes. No one will likely get 20 but per Euro many get 12+.
