Thursday may actually setup nicely for a possible chase across extreme SW/SC Iowa into NW/C Missouri particularly towards the evening hours. Good strong 500mb flow...and focus along the boundary to get action going. 0-3km CAPE 100-150 j/kg and 30-40 kt. of deep shear may be the right mix for supercells and maybe a few weak tornadoes. This looks like the best supercell threat area will be along and east of a Shenandoah IA to Columbia MO line. Just something to keep an eye on...
