@MN Transplant I think you’re right for TX. Based on my experience in 2017, the reduced solar will suppress convection for 2-3 hours centered on totality. Cumulus field totally dissipated in South Carolina in 2017 when I was there and reformed after.
Still seems like best case for TX is for the storm/trough to be more consolidated and push through with force Sunday and clear behind on Monday. Trend on guidance though is for another shortwave to dump into the trough and get stuck near the 4 corners area.
