An outlier severe weather and tornado case to say the list. Adjusted NMDA threshold to the bottom value of 0.06 to detect weak MESO’s and the NTDA percentage to 10%. The tornadoes to the east to the RDA I warned on based on the ground truth to the north and what they may have seen outside the WFO DMX. Tornado Probs 10-20% were yielding the tornadoes with very strong inbound velocities. The inflow ahead and along the warm front was strong. The image below is the 2018 UTC 0.5 DEG SRM with NTDA and NMDA algorithms overlayed. Also, the TOR polygons I issued were overlayed. Slider Bars and ground truth was the key to this event.
