After a relative lull in severe potential mid-week, latest guidance indicates increasing severe possibilities late week. Compared to 24 hours ago, deterministic models have vastly changed to an evolution of a shortwave trough digging south from the Canadian Rockies into the Lower CO Valley during D5-7/Wednesday-Friday. This would support a greater breadth and quality of western Gulf moisture advection across the central states beneath an initially pronounced EML. SPC and NSSL GEFS-based ML guidance indicate
