Ostrich December

Can we trend this the right direction more or do we suck at that View attachment 58357
Problem I saw last night is that +PNA sliding East from this point going forward. I don’t love the WAR but it doesn’t necessarily hurt us if it stays where it’s at. What do you see? Can we get that trough to dig in long enough to let a southern stream wave make a pass?
 
If we can slow that wave entering the Pacific Northwest down to keep our +PNA in place a touch longer then we might have a chance?
 
I know I said that a phasing Baja wave wasn’t likely, but now I take back that it’s impossible. I think that we could get a phase with better trends, but this is another, I’ll see it when I believe it situation.

I agree, I'd like to see a second piece of energy in the N/S dive behind this Christmas anafrontal miracle, because chances are that big trough the GFS keeps showing will move out, or if the Baja energy caught up and interacted w/ it we'd be too warm. Instead it'd be nice to see that trough position itself more as a 50/50 low for a storm on the 27/28th. GFS did this on yesterday's 18z, but it's not shown up since and I'm not confident it will again.
 
If we can get the Baja wave to move over into the red circled area about 500-600 miles to the east, we'll have a classic southern slider/overunning event on our hands because it's plenty cold enough to snow at least to the I-20 corridor w/ this deep longwave trough centered near the Lakes

Plenty of time to do so still, my expectations are very low but it’s still very possible

We're getting closer. These southwestern US/northern Mexico cut off upper lows are so fickle though, they can easily trend 500 miles+ inside day 3-4 in or against our favor. I'd like to see the wave come a little more east and north so it's more deeply embedded in the westerly flow (moves faster east if it's further north) & is further east so timing wise it comes out and starts throwing moisture into this arctic air mass before it leaves

This is how we determined our state borders in South Carolina.

We just can't buy anything but an apps cutter. You would think, just by the odds, we could eventually get a gulf coast track but we just can't. These apps cutters, especially with marginal cold, just aren't going to do it.?
 
And honestly the ingredients are there to pop a coastal off the Carolina coast if enough energy drops down out of Montana on the 26/27th. It’ll be moving fast. Ensembles showing any OBX snow around that timeframe? Hmm
