Brad Panovich is calling today's flash flood a 200-year rainfall event.

Right now the winds in the line of Severe Thunderstorms over North Dakota are below Hurricane force.

Another tornado in southwest Missouri a bit ago. Actually one of the more ominous signatures I've seen all year apart from Kankakee and Enid.

With vertical instability of this caliber underneath an inversion layer like this, you can legitimately go from a small puff of cumulus humulus to a full mature supercell over a 100miles long in the span of 30minutes.
Obviously this is the 3km NAM here and over 2days out. Nebraska really has a low chance of seeing convection even with this environment because the forcing mechanism will be too far north.

8900 CAPE?! Holy $hit! It's worth noting a wet bulb temp of 88 is considered deadly for healthy adults. 86 is deadly for young children and the elderly. This sounding is showing around 83 or 84.
