OT: Major West Coast winter storm where some will see over 150 inches of snow

Actually, that's a misnomer - nor'easter is used to describe the predominant winds out of the northeast at the coast from such storms, which keep the winds mostly over land (colder) and often lead to snow. The fact that the storms usually move NE is a coincidence for the naming (over 100 years ago, nobody knew which way a storm was moving, but they knew which way the winds were blowing in a fierce coastal storm).

Thank you. I've always been confused by the wind direction because it seems to me it would be different at different points. I'll remember that it has to do with the wind at the coast. BTW, didn't Benjamin Franklin do some research into how nor'easters work, using the various directions in which trees fell in different places?

I agree with that. Hate snow- it’s a giant pain in the ass for me on several levels, but I appreciate the info so I can make educated decisions to plan ahead.

If you listen to him rather than the official forecast you would have prepared yourself for a 2-4 inch snowfall that never came nor was ever forecasted

Ask him. He felt and feels the need to post the worst possible scenario every single time. Defending Philly news stations when he doesn't live here was strange. BTW that "big" storm was a complete bust. Lots of business closed because of a dusting or rain. My point is what is the rush??? I still don't get it.

And thats the issue...the hype began last night for this storm yet 5 days out we have no clarity even today. We have seen these storms give us big dumps of snow as well as slop to rain and mostly rain. Therms for this at the moment are questionable
 
A thread in which WhiteBus accuses someone of loving to argue for the sake of it and Bac suggests someone lacks self awareness - that's all-time!

Please pin this thread for future reference and lulz.
 
You are doing the same thing

Self awareness would help
C’mon man. You can do better than that. I’m fine and don’t have a history of being a dick in these threads. You do and you should own it. But thanks for the self awareness advice Dr. Phil. I find it funny that I didn’t expose you clowns by name in my initial post, but you trotted yourselves out anyway.

I disagree with this point. He has a snow bias for sure but always lays out the scenarios and qualifies things. Given that we’re still in this COVID thing, not sure the early storm predictions had a major impact here.

A lot of us like the day to day of following a storm to fruition no matter if predictions were correct. The more perspectives the better. The annoying trolling from the same people for years is so tiring already. Just stay out of the thread.
This is their excitement as trolls.

And they say #s only reports info not predicts anything. But he sure does edit it to the worst case scenario every single time. Such a saint.
 
Like the stock market, the weather is not an exact science nor is it predictable. I for one appreciate #’s posts. Why don’t you folks that have such disdain for these posts just not read or follow them? Life is too short. I can’t understand the derision. I’m not trying to single you out because I like you posts on other topics but don’t understand the hate in the weather posts by many on this board.

The worst part is he's a meteorologist, but won't even comment on these threads, which is a shame, as we could use some good input. Let's see if we can get @RUJohnny to post, though - he nailed the 12/16 storm.
Just way too many inputs to nail down a solution at this point. Too many vorts, and need to clear out tomorrow's southern miss to set up the height field in its wake in order to figure what happens Sun night. If I had to forecast now I'd just say plowable event possible statewide, potential for a long duration, high impact event.
 
Well, given that all 4 major models (Euro, UK, CMC, and GFS, as well as every lesser known model) are showing a major winter storm traversing the US from the west coast (currently getting crushed with rain and mountain snows) today and tomorrow, through the central Plains by Saturday and the Ohio Valley on Sunday, reaching our area late Sunday/early Monday (depending on the model) and then redeveloping off the NC/VA coast and hammering most of our area with generally 8-12" of snow (only the UK shows a bit less - more like 5-9") and more than 12" for many (and this storm is hitting everywhere from DC to Maine), mostly from late Sunday through Monday (but into Tuesday on some), it's time to start a new thread, as we're now within 5 days of the start of the event. I don't intend to paste a bunch of model runs in this thread until we're maybe 3 days out (like Thurs night; others can, of course), as they're going to shift some (maybe a lot) until we're closer to the event (and the system isn't over land, with better data inputs to the models until tomorrow afternoon).

Like any potential major storm, the details are highly uncertain 4-5 days out, with outcomes being somewhat different across the models which is to be expected this far out. The point isn't to debate the exact details of who will get how much snow/rain and when, but just to recognize that a significant winter storm is looking likely for our area, with a wide range of potential wintry outcomes. Just as a point of comparison, though, this system looks to be at least as imposing as the 12/16 system did at 4-5 days out on the models.

It's possible that the cold air in place could still suppress the storm causing it to largely miss us to the south, although even the least snowy case is likely still a few inches for everyone from the initial low before it redevelops off the coast). And it's also possible the storm takes a track much closer to the coast bringing in much more rain, especially for 95 and SE of there. A third thing that could go "wrong" is that the northern and southern stream systems don't "phase" well, leading to a much weaker storm with less precip. But right now the models are all showing a pretty classic Miller B system approaching from the west (with the lighter snows possible on Sunday) and then transferring its energy to a coastal low, which heads NE as a nor'easter bringing heavy wintry precip to our area.

With respect to the models, the Euro is a major snowstorm with 8-14" for everyone except less, due to rain, about 20-30 miles SE of 95 and maybe only a few inches at the coast. The Euro is the slowest model, bringing precip in early Monday and lasting into late Tuesday. The Canadian shows 7-12" (with a few lollipops up to 15") for essentially everyone, except near Cape May, due to some mixing; it starts late Sunday night and goes through early Tuesday. The GFS shows 8-14" for everyone N of 276/195, with 4-8" south of that line due to mixing; the GFS starts with some light snow Sunday afternoon, but the main snow is late Sunday through late Monday. Finally, the UK is showing a bit less snowfall than the other models, as it's a bit further offshore, so less precip - it's showing 6-9" for NYC metro and NENJ from Monmouth/Middlesex up through Bergen, but less N and W of there (4-6") and south of 195 (3-6"); the UK also shows precip from late Sunday through early Tuesday. Lots more to come, I'm sure. The usual links below...

And with regard to what's heading here, this is a really good tweet thread from Jim Sullivan from WeatherWorks (a local outfit many here like) on why he thinks this could be a significant winter storm for the midwest and mid-Atlantic/Northeast. He explains the teleconnections and drivers pretty well.


It was our weekly poker night (COVID home game is on line now - will start a thread on that if people are interested in the on-line site we use), so I missed all the bickering and will try to not engage since it's pointless. I will just say this though: I didn't start any of the arguing and I never post about my love for snow in these threads since some dislike that so I leave it out, in an attempt to not start arguments.

Anyway back to the storm. Tonight's 0Z models are all in and there is even a bit higher confidence in a major (major is 8-12" to me) winter storm for most of the Philly-NJ-NYC region (and most places from DC to Boston). We're still about 4 days out from the start of the storm, as depicted by every model now (they all start with some light snow by late Sunday afternoon to Sunday late evening (the spread on start/end times was about 18 hours, 12 hours ago and is now <6 hours, which indicates better consensus/confidence); the end times are Tues morning/afternoon on all of the models (it's a long duration storm, as modeled). And 3 of the 4 global models show widespread "historic" snowfall amounts (12-20" for me; one can debate the descriptor, so that's why I include the amounts) for most of CNJ/NNJ/NYC. With respect to the big picture model details...
  • The Euro shows a major to historic snowstorm for all of CNJ/NNJ/NYC/EPA with 12-16" of snow for everyone N of 195/276 and 6-12" everywhere else in EPA/SNJ S of 195/276, except for about 3-6" for SE of Salem to Toms River. These lower amounts are due to mixing/change to sleet/rain at times.
  • The Canadian shows a historic snowstorm for all of CNJ/NNJ/NYC/LI and Monmouth/Ocean with a range of 12-20", but with 20-26" for the eastern parts of Middlesex to Bergen and all of NYC/LI. The CMC has a general 8-12" for EPA and the rest of SNJ/Phillly (even down to Cape May. The CMC probably represents the ceiling with this storm and nobody is going to predict that as an outcome without every other model in line with it <1 day out.
  • The GFS shows 12-16" for NENJ from Monmouth up to Bergen and for NYC/LI and 8-12" for the western 1/3 of CNJ/NNJ (Merceer-Hunterdon-Warren) and E-PA N of 276 and has 3-6" for SEPA and SNJ S of 276/195 (except much of Monmouth, as per above) and only a few inches for SENJ, again due to sleet/rain.
  • Finally, the UK is now only showing a little less snowfall than the other models, as it's no longer further offshore (it had a fair amount less earlier today). It's showing 6-12" for everywhere in EPA/NJ N of 276/195 and for NYC/LI, including a decent area of 12-16" N of 80 in NNJ and the HV. South of 276/195 is about 3-6" with less towards the coast and far SNJ, due to mixing/changeover.
  • One other thing to keep in mind: if this storm ends up being anything like modeled, there will be mesoscale deformation snowbands that setup which will put down an extra several inches of snow in some spots (these are normally SW to NE oriented and well inland of the surface low and are often about 20 miles wide by 50-75 miles long), but we won't know where they set up until the storm hits.
  • With the primary surface low still off the US West Coast, the data inputs are still sparser than they'll be tomorrow afternoon, after the system comes ashore, so, in theory, we should have higher confidence forecasts starting tomorrow night, as the data inputs will be more complete and we'll be closer to the event. But that doesn't always happen that way. Figure I'll post snowfall maps starting tomorrow night (another reason not to is that they don't always remain for reasons I can't figure out, as I host them on imgur - those big red X's). The usual links below including to the free model output sites I usually use and which are pretty easy to use.
So, some will read all that and think I'm predicting an 8-12" or even 12-20" snowstorm for most of us. No, I'd never do that this far out, but confidence is pretty high in at least several inches of snow and is growing in getting at least 8", but a coastal hugger track bringing a fair amount of rain to the 95 corridor/coast is still on the table, as is a mostly suppressed storm to our south that might only given a few to several inches of snow primarily SE of 95 and towards the coast. A complete whiff is almost off the table (and will be if we still have a pretty good consensus tomorrow night), but a storm that's just weaker with less precip is also possible.

For some perspective, we're 4 days out and in the modern era of numerical weather prediction (last 20-25 years or so) we've had one horrible complete bust for everyone in this area (March 2001, which was off by 100+ miles) vs. what was forecasted right up until the storm start and one mostly bad bust for this area (Jan-2015, where the forecast for Philly and most of NJ was way way off, while eastern NJ/coastal NJ/NYC were off, but not nearly as badly. Those two and especially Jan-2015, which was recent, as some major advances have been made in modeling since 2001, will always make any forecasters reluctant to predict big snowstorms 4 days out let alone even 2-3 days out.

We've also had some other modest busts on some big storms, where some areas busted, but other areas didn't (like last month on 12/16) and we've also had some pretty good forecasts on big storms from a few days out (not always 4 days, though), including Jan-96, Dec-2000, Feb-2003, Dec-2003, Feb-2006, Feb-2010, Dec-2010, Jan-2011, Feb-2014, and Jan-2016, which were all 12" or more storms in NYC (and much of CNJ/NNJ). The point is, for forecasted big storms, most of them have been forecasted pretty decently (never perfectly) from a few to several days out, with a few major busts.
 
If you listen to him rather than the official forecast you would have prepared yourself for a 2-4 inch snowfall that never came nor was ever forecasted

Numbers loves the applause and does post very valuable stuff but he and his peanut gallery need to grow tougher skins on stuff they do not get right.
Weak. 3.5 days before the event started I said, "At this point, I'd say a general 2-4" snowfall is starting to look likely, with the potential for a 4-8" event still on the table, as well as the potential for just a 1-2" event." Even if you think that's a 2-4" forecast (I don't), it was 84 hours before the event - there wasn't even an official forecast out yet and who takes info from 3+ days out and "prepares oneself" for that forecast without checking back in as the event gets closer? Nobody.

Then ~60 hours before the start of the event I said 1-3" was looking more likely and then 48 hours before the event, as the models continued to show less and less snow, I showed the NWS 1-2" statewide snowfall forecast and mentioned how it was likely overdone given the models showing <1" for large parts of NJ. I would think anyone smart enough to check back in at that point would've seen that this was now a pretty minor event (I also changed the thread title to "minor" at that point).

And finally about 30 hours before the event, I was questioning why so many mets/media sources were calling for 1-3" when the models weren't showing that and I was saying <1" south of 78 and maybe 1-2" N of 78 was more likely - and that's what we actually got. You need to do a little better homework before you make patently wrong claims about what I said on that thread.

The NAVGEM? Really? You know you'd be laughed out of the storm thread on the weather boards if you tried to use the crappy NAVGEM to make a point about a storm. I'd actually like to see that, so please do. And for the record, the 0Z NAVGEM shows an historic blizzard for the region. Also, talking about individual ensemble members is just silly. All that really matters is the ensemble mean and how different it might be from the operational run, showing the sensitivity of the model run to the initial conditions, mostly.
 
Ask him. He felt and feels the need to post the worst possible scenario every single time. Defending Philly news stations when he doesn't live here was strange. BTW that "big" storm was a complete bust. Lots of business closed because of a dusting or rain. My point is what is the rush??? I still don't get it.
Read my reply to bac on Tuesday's storm. Yes, the models 4-5 days out were wrong, but I quickly responded to the change in models and actually was noting how the NWS/media forecasts 1-2 days before the event were likely overdone. That's certainly not "posting the worst possible scenario every single time." Same thing on 12/16, where I strongly questioned the NWS having 12-18" for most of the area just NW of 95 - I said I thought 8-12" was a much better call (and 6-10" would've been even better, in hindsight).
 
Just way too many inputs to nail down a solution at this point. Too many vorts, and need to clear out tomorrow's southern miss to set up the height field in its wake in order to figure what happens Sun night. If I had to forecast now I'd just say plowable event possible statewide, potential for a long duration, high impact event.
Well said, thanks for posting. Sounds similar to my bottom line in the long post I just made, where I said, "confidence is pretty high in at least several inches of snow and is growing in getting at least 8"." and then went on to outline a few of the things that might cause this to not be a major storm. Of course I also highlighted the major impact that the models are indicating is quite possible. Will you be doing an "official" forecast? If so, would be great if you could share it here.
 
Thank you. I've always been confused by the wind direction because it seems to me it would be different at different points. I'll remember that it has to do with the wind at the coast. BTW, didn't Benjamin Franklin do some research into how nor'easters work, using the various directions in which trees fell in different places?
I don't know about the tree thing, but as per the linked article, he was one of the first people to establish that a storm's wind direction (like in a nor'easter) has nothing to do with the direction the storm is traveling, per se, as he corresponded with his brother about weather conditions during an eclipse with his brother in Boston and figured out that the storm he had experienced didn't hit Boston for several hours indicating that is must have moved NE-ward. Pretty clever dude.
