There is very strong capping in place today.
At 700mb a surge of warm air from 14C in TX to 11C thru the mid Plains.
Also noticed in the long-range model runs a large Omega Block could be setting up over CONUS with mid-level lows off west Conus and other SW of Greenland.
That will create an entrenched ridge over CONUS and block mid-level PV anomalies from spinning up TUTTs in the usual spot around 30N 65W.
Might start seeing some tropical action in a week or so.
