Some unusual strong wording from MRX in their AFD for Wednesday/Night severe chances. “Much uncertainty still exists in the location, type(s), and magnitude of potential severe weather with this mid-week system. With respect to the cyclogenesis expected to occur on Wednesday, the GFS is the most aggressive deterministic model, suggesting the surface low to strengthen below 995mb as it moves into the lower Midwest. The ECMWF and CMC guidance are less aggressive with the CMC holding a more northerly track towards the Great Lakes. The strength and track of the system is key for efficiency of surface-based WAA and sufficient instability in our area. In any solution, strong deep- layer and low-level shear is expected, along with a veering vertical wind profile. The GFS solution, being most aggressive, suggests surface-based instability sufficient for organized supercellular convection Wednesday afternoon into Wednesday night in southern portions of the area at a minimum. With this solution, a threat for all types of severe weather exists. However, the ECMWF and CMC solutions keep instability and convection as elevated with possible threats for damaging winds and hail. Ensemble solutions also vary significantly. Ultimately, this system will certainly be something to watch as we head into next week since potential exists for notable severe weather across southern portions of the U.S” .
