It does try to get there though. It's below freezing in Oklahoma Friday and holds it for a little while, the overrunning system is on it causing the issues. It waits for it to come through before sending more cold (though I don't think it's cold enough.)
In essence all the models are converging on the same idea. A bitter cold air mass will pool in along the Rockies. How they discern the TPV orientation and what vorticity pieces opens the gates is the difference.
What's your thought on the orientation?
I like the ICON's initial handling. -PNA supports a westward lean at the start and a pivot. GFS strings it out too fast because it wants to transfer the vorticity into the Atlantic which with a block, not favoring it. In terms of cold push, the ICON too started the faster trend and the others have followed the past several days.
