Agreed for the most part. I think there's a few ways we can score still -
1) Super high heat, ring of fire ridge type derecho event (June 2012 esque)
2) A high instability day where a lone cell or two can really blow up and cause a stripe of hail/very damaging wind (but large enough to not be considered super isolated)
I'm holding out hope that we can get a strong front still at some point with some sort of EML type airmass and having the warm front nearby but north of us. That's very wishful thinking though. We are probably into summer pulse season for the most part.
