I could be incorrect but the track of the surface low (especially on the 12z NAM) seems odd. It runs from Brownsville to Houston then due north from Dallas to Tulsa. Not saying it won’t happen that way but it isn’t typical from what I recall.
Our best track for snow is roughly Houston to Shreveport to Memphis. Doesn’t look promising. To Jomo’s point, if the west trend continues, frozen precip may end up west of OKC and Wichita.
