Looked like there was a small tongue of richer theta-e air poking right into that supercell's inflow zone. Saw this on the SPC Mesoscale page. Looked like it hit the best of all worlds there on the Red River and slightly off the dryline.
The Mesoanalysis page did show that, and it was a pretty localized, though impressive poke, in fact it was one of the main things yesterday evening that caught my attention and I mentioned on pg. 7 of the NOW thread at around 6 p.m. or so, how it was poking and pooling right into the Ardmore area. Your right, it was as if everything was coming together in that localized area around Ardmore and points East, the only thing that prevented this from being an even larger tornado event, was the fact that the DL started surging East quickly enough to overtake the discrete cells shortly after they had reached the favorable environment, unfortunately it just wasn’t quick enough for the community of Lone Grove. Had the DL held off to the West just a tad longer, the Lone Grove cell, as well as the one just to its south, would have continued NE into the favorable environment while likely continuing to produce tornadoes.
