The NTDA and NMDA for KENX had significant shortcomings for the 15 May 2018 event in the ALY CWA. The algorithms struggled to detect clear mesocyclones in cases where a significant hail spike was present. Could this hail spike be interrupting velocity data and causing unnecessary filtering of the algorithm? Also note that the velocity data appears to be more convergent, possibly due in part to the hail spike.
