Some good reading if you're interested in some theory/explanation of the failure modes that led to a lack of a historic outbreak yesterday. Edwards is one of the forecasters that did the 13z outlook so definitely some valuable insight.
Found this through a page on the Target Area of Storm Track if anyone is interested in exploring the topic further. Some very interesting points from Jeff Duda discussing the event, one thing that stuck out to me was his discussion of the very deep nearly saturated inflow layer and its impacts along with general severe weather enthusiasts (such as myself) over reliance on the HRRR and the importance of utilizing various tools and different CAM's. Defintiely a thread worth a read.
