In-depth meteorological discussion of one of the more prolific early-season tornado outbreaks in recent years: the March 2, 2012, outbreak that included the Henryville, IN, EF-4. In this video, we'll do a deep dive into the meteorology behind the Henryville supercell, including why this area within the broad severe risk area ended up being the most favorable for significant tornadoes. We'll also discuss additional supercells that spawned killer tornadoes that ravaged West Liberty and Salyersville, KY, including how they were able to continue to produce significant tornadoes despite outrunning the warm sector.
