The directional shear didn't seem as impressive to me as some of the bigger outbreaks. But this one has some steep mid level lapse rates and strong wind velocities to maybe offset the lack of directional shear.
Outbreaks are very difficult to predict in terms of how many SUP cells or intense tors. One or two ingredients can be altered slightly which is the difference between St Patty's Day 2021 and April 2011.
