The GFS and WRF are on different planets right now. They both seem to handle the upper level system closely, but the surface conditions are wildly different.
If I am to believe the GFS (which I am wishcasting with right now), there is a marginal chance of severe weather in northwest Kansas on Saturday and in west-central Texas on Sunday. I'm not inclined to get too detailed at the moment as things will likely change a lot by the next run, but I'm keeping my eyes out.
