"This is an uncommon, upper-echelon parameter space. In such an environment, any relatively discrete supercells will be capable of multiple tornadoes, some long-tracked and strong to violent (EF2-5 possible), with considerable destructive potential. A very moist boundary layer also will reduce potential cold-pool/outflow strength via less subcloud evaporation, so that even closely spaced storms may have substantial tornado threats. Forecast wind fields and model soundings reasonably suggest any sustained supercells and their tornadoes will be fast-moving (45-55 kt), with individual tornado paths nearly as long in miles as their duration in minutes."
Hoping it doesn't end up as bad as it could be, not often you get wording like that.
