Tim.... I (and my chase partners) were on that storm from initiation in northwestern KS. It was pretty LP from the get-go. While it was tornado-warned pretty much it's whole life in northenr KS, it was quite high-based and, while visually impressive with it's nice LP-esque updraft, had quite poor low-level rotation. IT was until it got very near the NE/KS border that a nice wallcloud developed. There was one attempt at a tornado, and it actually might have produced a tornado briefly, just south of the border, but there was a much more successful attempt as the storm neared REd Cloud. Personally, I think this was my favorite night-time tornado -- second only to the Anthony/Harper nighttime tornado on 5/12...
