Confirmed tornado near Plattsmouth, NE as well, moving into Iowa now. 85 mph storm motion according to the warning text.

The line is moving into the MDT area now. I guess the question is whether we get discrete supercellular development ahead of the line at some point.

Do we know if there are going to be any special soundings from e.g. Des Moines?

I don't know about special soundings, but the HRRR forecast soundings from a few runs ago showed some SBCINH remaining ahead of the line which *should* keep it as the only game in town...but it's quite a game.

And to think this is just now entering the moderate risk. This system is absolutely bonkers.

Yeah, mesoanalysis has eastern Iowa still capped for now, but it looks like the cap has eroded in the area immediately in front of the line in west-central Iowa.

Based on the radar, it looks like the bowing segment north of Omaha is producing 85 mph winds.
