A midlevel shortwave trough over the central Plains this morning will progress eastward to the middle MS Valley by this evening and the OH Valley overnight. A lingering plume of steep midlevel lapse rates precedes the midlevel trough, with sufficient midlevel moisture for very weak buoyancy (MUCAPE 100-200 J/kg, rooted near or above the 700 mb level).
