Note the flash trend in this sector and the associated lightning jumps. The pink is a 12 sigma jump.
BAJ
Note: This jump was primarily related to a storm merger — this is something that should be addressed with training as a limitation of the product. (K. Calhoun)
Radar signatures clearly indicated this storm deserved a severe thunderstorm warning about 5 minutes before ProbSevere exceeded 60% or any lightning jump was evident. ProbSevere and the lightning jump did eventually catch on, jumping to 99% and 4-sigma, respectively.
-Toki Wartooth
The storm that prompted the severe thunderstorm warning #2 continued to show the potential of severe weather. Both radar signatures as well as ProbSevere and the Lightning jump algorithm show this possibility.

Pulled the trigger on the second severe thunderstorm warning of the day. Radar signatures (60 dBZ to -20C, TBSS) began to indicate hail was possible at roughly the same time that ProbSevere jumped to around 80% and there was a 7-sigma lightning jump. I was ready to pull the trigger when I saw the radar signatures, but the ProbSevere and lightning jump gave me more confidence on the warning.

KICT was down for us, but we relayed with OUN on warning (also pulled up the Topeka radar to help).
