A nice case study of the October 26, 2006 cold-core tornado outbreak is presented by Jon Davies at the URL below. John Davies has published several articles concerning the typical synoptic and mesoscale features of cold-core tornado events, including Davies and Guyer (2004).
Many of the tornadoes observed on October 26 appear to be non-supercell tornadoes or landspouts, which are those not associated with a deep persistent mesocyclone. Landspouts are typically much weaker than supercell tornadoes, and form via the stretching by an updraft (from a cumulus cloud or thunderstorm) of pre-existing vorticity or rotation associated with surface boundaries.
