Wintry 1/9-12 Winter Potential Great Dane or Yorkie

Surely this won’t do any shifts of this magnitude anymore and we’ll all live happily ever after
i think that the most underrated thing to look at is the PNW ridge. it was much weaker this run. the ridge has a lot of influence on how much that piece digs and a weaker ridge means less digging.
00Z GFS took the surface low from 997 to 974 in 12 hours. This could have been even bigger.

there's a certain quality to that gfs run that really pissed me off. big hit in spite of never having its act together

I really disregard the GFS surface output almost always. And frankly, we shouldn't put any stock into it's H5 output beyond about D4-5 lol. I feel like this winter is really revealing just how bad it is in many areas.

About the fastest pressure drops you will see with winter storms in the SE is a drop of 10mb in 6 hours - so yeah, that was rapid deepening. Here, the Superstorm pressure drop

This entire setup is weird to me. Usually to get a big storm, we need one of two things.

1. A dominant northern stream energy that picks up southern energy, digs, and cuts off. (January 2000, January 2002)

2. A suppressed dominant southern low that is fed cold air from an exiting SE Canada low (December 2018, February 2004)

This setup relies on two dominant northern and southern pieces phasing at the same time, seperate from our cold source ( the SE Canada low).

Crazier things have happened, and needles can be threaded, but this setup raises a lot of red flags in my mind. I have a hard time buying the possibility of a big storm.

If you all can think of any analogs where this setup has worked, let me know.

That's the type of dynamics that could be in play here. That's why I said before, if 2-4" is all we can muster out of this, it will be one heckuva a loss of potential and 2-4" is going to be hard for me to take as a consolation prize. There are many events where squeezing out an extra inch or two feels like you've scaled Everest, this ain't one of them.
 
I said it in jest earlier but keeping the Icon and Canadian in the suppressed camp at 12z earlier was critical. Kept us alive. CMC staying in that camp tonight is a win as well. Our spread needs to remain as south as possible through the weekend. We ain’t cooked. We cooking
 
UKMet is kind of bad in all ways. Misses the phase with baja wave and wave digging into the S Plains is on the weak side, and it's warm across the south

I'm not sure I'm buying what the 00z UKMET was selling. It sure looked like it should have phased with the ull.

Put all the operational models and ensemble members into the bouncycorn model blender though, and we have something to keep tracking
