Late to this case, but the 12Z and 15Z data would have found me in Boise City, OK. It looks like a pretty classic high Plains setup with good moisture making it into southeastern CO. Further south seems too capped for my taste with nothing obvious to break it loose. The higher surface elevations of eastern CO and NM and pretty good flow profiles should break things loose, with storms moving north of east at a pretty sedate 20 kts. or so.
The 18Z data seems to confirm the previous, with cells developing already in a line from about Lamar into northeast NM. After lunch I'm deciding to get a little closer to storms that may develop off the outflow of this line. I'm going to amble up to Springfield, CO, by 19Z. Mid 60's dewpoints and backed south-southeast winds work pretty well in that area.
