In the high CAPE, low shear environment not favorable for the EF-5 tornado that occurred, a local intensification mechanism was necessary. Real-data WRF simulations are used to reproduce behavior observed in the event such as storm mergers and other storm intensification mechanisms. Soundings retrieved from the near-storm environment in those runs are used in idealized simulations to test storm morphology resulting from minor modifications in the shear and thermodynamic profiles. Allowing for tests without the effects of boundaries and storm interactions, the idealized runs help to identify the effects of individual changes in the local storm environment. This work reproduces and identifies modifications in the local environment leading to the rapid intensification of the mesocyclone prior to tornadogenesis.
