Your snowfall estimates are pretty benign for such a nice pattern though.

Relatively conservative, and I think the correction vector is upwards with those, but keep in mind that I also expect some not so favorable tracks, too. At the end of the day, snowfall is an educated guess.

But yes, maybe I get 90" instead of 65" if we get lucky.

Gotta hedge for being unlucky sometimes....we remember the good patterns that smoked us, but sometimes we have good patterns that don't produce...there's been some big disappointments in good patterns before (see Dec 1987, Jan 1985, Feb 2010 in SNE, Jan/Feb 1980)

Man, the '80s sucked considering we had some good patterns, lol

This is something that you can only completely appreciate with forecasting experience....took me several years of doing those outlooks to grasp it, but those 2018, and 2019 double-busts taught me a great deal.

You especially have to be careful in la nina because its much more difficult to get an epic season as compared to el nino.

We could replicate 2010-2011 10 more times, and maybe do as well in one of those simulations....don't forget that.

That’s a good point, to get those insane snowfall totals you need both a great pattern AND luck. That Feb 2021 storm mu area got 8 inches or so, but just a 20 min drive NW and there was 18 inches of snow on the ground. It’s very easy to get screwed like that even in good patterns especially closer to the coast.

Anyone remember the December 23-26, 2010 Winter Storm? Midwest storm occluded & formed a east coast low. Brought heavy snow Midwest, light snows in OV & heavy snow in NE. 

 

One of the GFS runs kind of hints at something like that & the Ensemble mean 500mb pattern favors it. Not saying it's happening, it's pastday 10 lol. I'm just sharing:

If you walk the 500mb through day by day of the 2010 Winter storm its almost exactly like above.

That's going to be another huge key too in order to have an extended period of fun and chances. If we get the initial block and it just sits there and slowly rots...we may still get some fun but we'll be playing with fire and maybe only get a chance or two. If we can get pattern re-loading we could get several-plus chances and this is how we can really cash in and pile up.

A rotten block in Dec/Jan is better than latter Feb/March. At least climo is still better. 

That being said the Pacific does actually improve over time so reloads are very possible

I'm not so sure I totally buy that. I think there are too many factors to consider to say it's better in one period vs. another.

I do see the similarities between the pattern that would be setting up to pattern in 2010-2011. But, it does seem that the pattern back in 2010/2011 seem to push a little further south. Just by a little. So the hope is the storms don't get deflected to the mid-atlantic only. But time will tell. It's still very exciting to track what's coming and I love seeing that we're all discussing this in a positive way.

Is there a modal upgrade today? What's being updated.

Parallel universe? 

But we're actually upgrading to 16.3 today. Looks like mainly some snow depth changes and increasing data assimilation (which could be important).

Yes

Hopefully the gfs is better this winter

Anyone ever considered making snow , air compressor , pressure washer, special snow nozzle for hose , anyone ever try this . Wether it’s for the kids to sled or for a holiday or whatever. I bet some have most of the ingredients except the nozzle 

A buddy of mine just did it yesterday up here with a pressure washer when the temps were mid 20's.
