Current supercell activity over KS and OK will consolidate in to a squall line later this evening as it moves in to western MO. This activity will try to move toward the area after midnight and may still produce gusty wind gusts and hail.
More potential will exist tomorrow afternoon and evening as instability and wind profiles will be conducive to produce at least some severe weather.
The mode and coverage is still in question and will have to be monitored as conditions develop. The highest chance of tornadic activity look to be to the southwest of St. Louis but we are not completely without some potential. Posting this latest graphic which is a leading indicator of tornado ingredients for tomorrow evening.
