I think you are in a good spot. I feel like this system is a classic look for going west of the QPF max/gradient for good snows...esp up that way when the mid level lows mature more.
TT has the cross sections. You can see PV from what looks to be a possible trop fold and low level PV close to the low center from WAA and latent heat release. A recipe for bombing.
I use it. A tool, like anything else. Sometimes it's good with very dynamic systems, sometimes it can be a little wrapped up. It's good for meso things like CAD etc.
