I’ve yet to ever even look at it 

You should check this one just academically because it's what we were talking about earlier in getting the vort more S - immediately you see that improve.  

There's definitely an odd moisture deficit going on... It's almost like we're getting a negative feed-back over the continent because of the lack of cyclone traffic.   These potent but compressed waves are failing to generate inflow pooling of theta-e into the S, whereby subsequent wave traffic have that source available to them.   Something like this ... that ICON solution should be exploding frankly  - it may also be that it's at the time horizon of the models outer edge too...

Whats cutting in this pattern ?

Could easily have that 1/24-25 system cut. Depends how much phasing you get. Keeping the shortwave kind of separated from the main PV as long as possible is essential to getting a huge overrunning storm like we see in the 18z run….check out the 12z run if you want to see how it cuts.
