In case anyone is interested in my summary posted elsewhere, here you go. Well, Dr. No, the King, looks like he might be back, as most of the global models tonight at 0Z caved to the Euro depiction over the last several runs of a much more progressive, flatter storm much further to our SE. So, the chances of a major snowstorm have gone down substantially, but not to zero, and the chances of even a minor to moderate storm have gone down significantly. The AI models, which have done quite well in the 4-6 day range this winter, still show a moderate to significant storm (with only one model the AIGFS still showing a major snowstorm)., while all of the physics-based models show either no snow or only a few inches. The cries you heard last night were from all the snow lovers around the world, lol. Below is a summary of the 12Z to 0Z changes...

• The ICON went from a 12-18" monster for all to nada for everyone (1-2" for AC to Cape May). That's nuts.
• The GFS went from 6-12+" for everyone at 12Z to 2-5" for most at 0Z
• CMC went from an 18-24" monster for everyone at 12Z to <1" for everyone at 0Z. Also nuts.
• The UK went from 8-14" for everyone at 12Z to ~1" along 95 and a few inches for the coast at 0Z. More nuts.
• The Euro had little to no snow for everyone at both 12Z and 0Z. Dr. No.
• The AIGFS went from 12-18" for everyone at 12Z to 6-12" for everyone (the high end at the coast) at 0Z.
• The Euro-AIFS went from 6-12" for everyone at 12Z to 2-3" for 95/3-5" coast at 0Z.
• The Weathernext 2 went from 8-14" for everyone at 12Z to 2-3" for 95/3-5" coast at 0Z.

 

 

All models beat by a model that will be replaced lol. Why couldn't thebEURO be king in January 2015.

It’s a fragile setup in a fast moving pattern. Lots of things can shift around and ruin the storm setup. It’s still 4 days out but this wouldn’t be the first whiff or OTS this or last winter. 

I am not disappointed in the fact that a storm in the LR disappeared. Its the model performance. I have never seen this before.

The lead system out front develops a little faster so we get more confluence to the north this run as it becomes the 50/50 low. So the phase happens a little later and the 2nd system develops further southeast.

It’s tough to get an higher end event like some of the OPs were showing yesterday with systems so close together. Also the ridge axis out West is pressing too hard to the east like we have been seeing repeatedly this winter with many coastal lows tracking further south.

The hope with this one is that areas that are just under 25” on the season can pick up enough to cross the finish line.

Someone posted a while back the ocean temps, which were running well below average. The configuration of the temps off the coast would favor a further south track moving ENE. Wonder if this is part of the issue this year.

I think anyone that has been doing this for awhile knew that a perfect setup at day 6 was unlikely to hold regardless of model performance.    The Euro showing nothing at 12z yesterday was also big red flag.

I know. I have seen probably hundreds of storms dissappear. I have never seen a situation where ALL models including crap models like the JMA and ICON show something then its gone. 

2015 at least the EURO had the NAM by its side being INCORRECT).

Nice bump in the EPS mean, also...

The Euro is now teasing us - trying to make us all crazy............BTW anyone notice the mainstream media especially online now advertising this as a "big storm" ?

Deep down we all knew day 6 perfect setup was prone to disaster. Same script. Disappointing yes.

you don't want to be in the jackpot yet, let this trend northwest the next few days and we're at a blizzard warning! Think positive it could realistically happen. One thing to note, the later this storm develops the better because it has that chance of stalling developing and riding up the coast instead of just fast flowing and bouncing without impact! I wonder what I post today on my weather page! I'm sticking with a direct impact I think this comes back at least somewhat!

yes - but go back to Boxing Day 2010 here same thing  happened 4-6 days out

where is your evidence to support this theory of yours ?

Nam and Rgem are slightly more amped than 0z

84 hr. NAM is even more fun to look at - 12Z should be fun too

Seems fitting but this is like the winter Olympics final game, models version

USA, versus, Europe, versus the other countries.  Who will be crowned gold?

Stay tuned

americans have never dominated winter olympics.

Seasonal numerical forecasting euphoria to the doldrumms .  if you go back and check the threats / discussions from Jan 17/18 and the NC storm similar challenges with coastal formation and even some of the same models run to run changes.   Each situation is unique and perhaps as we go deeper into the season we can ween off the seasonal trends.

True, maybe we should look at any Norwegian forecast models?
