So right now the latest runs are showing big storm developments down through central and northern Nebraska around 5 PM. These sweep east and southeast through the state. Powerful storms also develop over NW Iowa and track southeast as well. Many of these storms appear to stay discrete for a decent period of time (that's when strong tornado formation is most likely).

CAPE values of 1500-3000+ are forecast. Forecasted shear values are extremly high during the time of storm formation and propagation in those areas. The helicity values are also supposed to be high. In short, all the ingredients for extremely strong storms and potentially strong tornadoes are forecast to be there. Now that daytime convective heating has started, I'd say we've got a good chance of seeing some serious sh#t go down. GI, Lincoln, Omaha, etc will be under the gun (basically most of central and eastern Nebraska). Most of Iowa will be, too.

The current storm in NE has reported 100 mph winds and golf ball sized hail. We'll see more of that. A lot more. A derecho wouldn't be surprising up in the northeast of Nebraska or NW of Iowa.

Dun, dun, dunnnnn. Dominator3 sighting around Omaha. That thing gets crazier looking with every new iteration.

And to think, I just "closed the book" per se on my past meteorology life. This statement right here opens it up again. As a sidenote: Sounds like you have some high level of knowledge (degree even?), looking for a copy of Holton's Dynamics book? It's the 4th edition though and currently it makes about as awful of a paperweight/doorstop as it does compelling read. I might be a bit biased though due to how ridiculous my dynamics class was.
