Severe Weather 3/9 - 3/12

12Z HRRR is...something. Two discrete rounds, and just about an ideal chasing scenario for me. Early one is far enough north and holds off just long enough that I could possibly get to it after work, and the late round fires before 23Z and remains discrete for much longer than earlier runs.
 
I'd say its certainly a solid possibility, especially if this scenario from the 12z HRRR holds:

Not only does it fire more discrete/semi-discrete convection in IL/IN, it fires KS/MO, which is also in a volitile environment.
Jeez, if this holds up, there’s going to be a lot of people who are going to be under not one but two tornado warnings this evening with the different rounds moving through.

13z HRRR goes full Nacho Libre on IL/IN, showing multiple discrete OWS cells in the first round, a discrete mode that quickly turns semi-discrete in the second, and perhaps most shockingly, a 3rd mode that starts off near the warm front as supercells before turning upscale. It also shows these cells lasting much longer as they tread eastward into Indiana and Michigan, with a warm front rider or two as well.

Utterly incredible parameter space near the warm front as well.

Kinematic profiles suggest that any surface-based warm sector
development should quickly become supercellular, with all severe
hazards possible, including very large hail and tornadoes. A strong
to intense tornado is possible, particularly with any storms ongoing
around 00Z when the low-level flow increases notably, resulting in
considerable elongation of the low-level hodograph
 
I think it's the job of the local meteorologists to translate the CIG risks into something that's accessible and understandable for their area - the SPC is producing these as more scientific and analytical forecasts not really intended to be put up as is on the 11pm news. I don't believe the general public/non-weather trackers are refreshing the SPC website for the detailed analysis used in these outlooks, so in my opinion I don't see a reason the SPC should have to appeal to the general public. I'd leave that to the local mets who best know their area and audience
