Well a 1042mb sprawling banana to our north in Canada definitely helps

It is what we have been missing in past years but is this real?  It is almost like models say this is what should be happening and the next run the same model comes back and says this is what you are getting and reality though in our new set up.

Even if the trough retracts westward, it looks more central CONUS-based rather than a deep -PNA as is typical in a Niña. Wouldn’t be a shit-the-blinds look. But let’s see what develops over the next 2 weeks first?

 

I noted the jet retraction in my earlier post. Seems he expects it to be temporary. As advertised the shift in the longwave pattern is relatively minor, and could potentially allow for a more significant storm.

Yea west coast ridge is my base level look for any hope of snow or cold in these parts anymore. I really, really hope this is a semi permanent festure this winter.

Cmc with a nice evolution around day 9. 

It's pretty obvious the first week of December isnt going to produce but as the pattern relaxes a bit maybe the second week of December can.

Ops and ensembles have all hinted at that over the last few days.

Hopefully as we get into next week something will show up more concretely.

18z GEFS really shifted away from last nights modeling of -EPO/+PNA in the medium-long range. Now it shows a Gulf of Alaska/Aleutian High pressure. Although the pattern may be getting wetter after Day 10, it may just be rain. 

Happy Thanksgiving! 

You know what I'm thankful for? The 'block user' feature on this forum.

Hard to complain about the advertised h5 pattern on the 12z EPS heading into mid Dec. Solid look out west, TPV stretched southward towards Hudson, and indications of +heights building westward into the NAO domain.

Don’t worry, people will find ways to complain.

GEFS is similar, almost identical
