May 19th had some decent hopes of structured supercells. SPC highlighted the southern Nebraska area for higher tornado threat, but we chose to play further south along the dryline. Late afternoon, a line of towers rapidly formed and back built south as the boundary drifted southeast. A couple of these storms exhibited supercellular features, but it wouldn’t be until late afternoon that the boundary rapidly built south with each tower stretching the vorticity along the boundary and producing numerous non-supercell tornadoes. What a crazy day! We saw 5 tornadoes, with the final one being a strong EF3.
