What am I missing there why those have TOR instead of PDS TOR as the hazard type?

The "Possible Hazard Type" window uses a set of criteria to identify, well, possible hazards. Here's a pic from the official paper about SHARPpy:

Note that, if certain parameters don't meet/exceed all listed criteria for a given hazard type, it'll move on to determine if they meet the next type on the list.

The two soundings you linked have some of the craziest hodos I’ve seen. Man. I am hoping things don’t pan out as modeled…

I agree. I almost want to frame that one hodo you posted. I do notice the critical angle is 70 vs. the more desired 90-degrees neighborhood. But the shape of this hodo & accompanying wind profiles it represents is classic.

Bleh, looks like we are going to have poor radar coverage for these storms.

Speaking of PDS watches and warnings, the GFS seems to agree with the HRRR about the evolution of a single monster supercell in central IA and this is what its forecasted sounding has to say...
