It's going to be a linear storm mode and the warm mid-level temps are going to prevent any kind of deep updraft development so there isn't much of a sigtor risk. This is why posting composite parameters with no other context is bad communication at best and clickbait at worst. All the STP is telling you is that threshold values of instability and shear are being met, you have to look at the broader context to determine whether those parameters are relevant to the forecast. You can have off-the-charts STP, but without supercells you're not going to get a substantial sigtor risk that would warrant higher probabilities. This is why people were criticizing them for the post.
