Iowa Supercell – Significant Tornado possible

Posted in News on by Brandon Smith.

An outlier severe weather event turned out a few classic supercells with tornadoes.  The algorithms performed well with this supercell with extreme values on the NMDA, and the NTDA having a 99+ percent chance for a tornado.  The V-R shear couplet was intense with a high probability of an intense tornado.  Would not be surprised if this was an EF2 or even an EF-3. High confidence tornado warning issued with these algorithms doing a stellar job with a tricky convective environment.

18 July 2019 KDMX 0.5 SRM with NMDA and NTDA overlaid. Impressive tornadic supercell with V-R Shear showing 58 knots of rotation with a shear value of 0.0625 s-1. It was a distance of 40 nm from the radar with an extreme MESO from the NMDA.
