prior to tornadogenesis was the only instance where flash rates from GLM17 increased slightly in tandem with GLM16 and ENTLN. All three MRMS variables also remained elevated until the end of the third tornado at 2026 UTC. Through the 270-min study of the supercell, GLM16 recorded 168% more flashes than GLM17. When accumulating the optical energy from all of the flashes from each sensor, GLM16 recorded 27% more optical energy than GLM17, which means that GLM17 observed 112% more optical energy per

simulations of marginally unstable environments, steeper LLLRs corresponded to stronger convection when compared to modest LLLRs. Additionally, in the eastern United States, where elevated mixed layers are rare compared to the plains, steep LR75s have shown high correlation with significant severe weather outbreaks ( Banacos and Ekster 2010 ). Other studies have noted that steep lapse rates corresponded to a greater likelihood of tornadogenesis ( Godfrey et al. 2004 ; Parker 2012 ) and damaging winds

the radar-observed process of cyclic tornado production, the following intriguing concurrent satellite observation is noted. At the time the cyclic tornadogenesis began, a thin line of cloud at the cirrus level and apparent in the visible satellite imagery ( Fig. 14 ) was noted extending from storm N southwestward through the Texas Panhandle into southeastern New Mexico. This line did not coincide with the location of the dryline as it was retreating westward ( Figs. 2c and 2d ). Cell N at 0130
