Indirectly, I think it holds some relevance. Climate change is leading to forces that make widespread, violent tornado activity—that is, outbreaks with multiple long-tracking supercell tornado families over a wide geographic area—less likely than it was prior to 1965 and especially prior to 2013. Certain models, including mesoscale such as the NAM/HRRR, still struggle to account for climate change’s impact on wavelengths vis-à-vis the warmer Pacific and the weaker AMOC signal in the Atlantic. Significant tornado outbreaks can still occur, but they are becoming less frequent, more limited in aerial coverage, and more confined to one (or two) big supercell that thrives more due to mesoscale quirks than large-scale synoptic factors vs. the past. Just a day and a half ago the GFS was suggesting a widespread SIGTOR threat from the Gulf Coast northward to IL/IN. Now the SIGTOR threat looks to be more confined, geographically, to parts of MS/AL and more dependent on boundaries than synoptic-scale factors, given that models have trended toward a higher-amplitude solution than a day and a half ago or so. Now we are still likely to see some significant tornadoes, but the potential “ceiling” does not look to be quite as menacing as it did earlier, though.
