It looks like there might be a decent chase day this coming Thursday across parts of southern Kansas and northern Oklahoma. It is still a long ways out so I'm sure a lot will change. This is also the first time I've looked at this setup on the GFS, so I have no idea how consistent the GFS has been with the evolution of this trough. Right now instability isn't that great due to somewhat low temperatures, but moisture and wind shear both look really good. It is definitely something to keep an eye on.
