I was at work last night on the 30th and there were several CGs (not to mention additional in-cloud stuff more than likely) over portions of west-central and central Missouri from, say 04z to 07z. Surface temps underneath were 19 degrees. Wow! The potential instability that was being created and released was around the 650-500mb layer or so right at the nose of the tremendous mid level PV anomaly. In the conceptual-model sense, this is about exactly the location in the compact mid-latitude cyclone where the Minneola, KS tornadoes occurred on 26 October. Very interesting stuff for sure.
