I've been looking over the data this morning... IF I were to go storm chasing locally (in southeast Missouri, southern Illinois or western Kentucky) my initial target be somewhere between Charleston, Mo and New Madrid, Mo. I like this area's atmospheric environment for storm development during the late morning/early afternoon.
I think storms will initiate in southeast Missouri and move in to western Kentucky and southern Illinois as maturing thunderstorms.
It is a tough call for a specific location due to having to deal with the Mississippi River. Storms will eventually cross over the river in to western Kentucky and those storms may be the better chasing storms. That is why I am hedging up towards the Charleston area because it gives me access to east, west and south.
