I actually am not a huge fan of the mlvl lapse rate output from COD. It always tends to want to bring in steep lapse rates. But...there were times throughout the summer where the look seemed to favor it, but there was one or two key pieces missing. not sure what exactly but you need the airmass to sort of remain homogeneous moving through the upper-Midwest and OV and that hasn't happened. Probably mT air from the Gulf being entrained into the mid-levels.
