What's that word when the same things happen over and over again and you expect the result to be different? ...

Don't say it, I know it already.  

It's not totally the same.  I don't care what the surface says this setup is way better. The trough axis isn't digging on top of us. Look at these panels. If something decided to develop it has more room then last time. The ridge/trough configuration is better. We were behind the 8 call from go needing some crazy capture and tuck solution last time because of where the trough was digging. This setup isn't as dire. Doesn't mean we get snow.  But I'm not convinced it would be a replay.

Guidance is converging on legit blocking Ji. Eps has a closed ridge near the pole before d10 and the d15 mean looks pretty much just like the gfs you posted. If the pna or epo flips in our favor I think it's game on not too far down the road. 

That big ridge NW of Alaska was there in November and that eventually moved over Alaska turning the Epo negative. IF history repeats, Epo tanks within a few days thereafter.

I think the problem is the trough is positively tilted. We need neutral or better, or it just scoops everything up and out to our north and east. Heck, the trough earlier in the run at 156-168 hrs. should have caused something to fall from the sky imho, but it was dry as a bone too for us.

Holy -NAO/-AO signal! Showing up in the +250dm contour on 18z GFS ensembles, and this will strengthen in size and maximum over the next few days. Probaby a +400-+500 peak verification. Nailed this Dec 8-27 +Stratosphere = -NAO mid-January thing. Must have said it 15 times. This will trend stronger: (Nice 4-wave split PV)

I guaranty you that sometime in the next 5 days we will have a good digital snowstorm show up. Probably multiple iterations. Having something hold in the short range will be the real challenge. Lol

Your 100% right that exactly as shown the trough is too positive and nothing is amplified enough. But there is way more room to get the subtle improvements needed there to get a storm then last time when the entire trough location was bad.

of course when the models show a cutter in the long range...nothing changes...

There were a lot of flags for a favorable track next weekend. Zero blocking, strong WAR, and no reason except for really lucky timing for something to run the gauntlet. What happens after that is the next chance unless just about everything going against the weekend deal suddenly fixes itself.

I think the first rainstorm tracking so far west killed the idea of the storm behind it giving us a favorable track. Lets see what D9 says...got something brewing lol

Lakes low/northern stream is going to make us mad. Don't worry though. I'm pretty much 100% sure we'll get a good digital storm this week.

if it was warm for 6 weeks and we were waiting for the cold pattern to come and we saw this model run tonight....we would be in pure panic

Another op run showing a very strong block forming over the pole. It can be abrupt sometimes and if it really is going to happen it's going to cause a lot of problems with ops and ens until it's resolved. 

yep....this certainly would mute/delay the 10-15 day warm period if its true
