The afternoon starts to heat up at 2356Z (5:56 pm CST).  Note the two cells in the upper right corner moving out of the area - one of these cells is the long-lived cell that traveled 400-500 miles (from Oklahoma-Kansas border to Indiana) in 14 hours.

In just one hour (7:00 pm CST), a whole new line of supercells has formed.  Note the long-lived cell has passed into Illinois by this time. 

8:00 pm CST.  The line of supercells extends down into Oklahoma now, and note the large cell over in Illinois (the long-lifer still traveling).

By 9:00 pm CST the storms are becoming more severe in the southern Missouri/northeastern Oklahoma areas.  Note the pink in the center of the cell in Oklahoma (very heavy rain).  The long-lifer cell keeps traveling northeast.

At 10:00 pm CST, the squall line has formed in Kansas.  This squall line kept me off the computer for the rest of the evening.  And the long-lifer cell is still going strong in the upper right corner.

By 11:00 pm CST, the squall line is well-formed and wreaking havoc in Missouri and the southeastern tip of Kansas/northeastern tip of Oklahoma.  Note the bow echo east of Kansas City (that's about where Sedalia is).  Also, the red cells on the Missouri/Arkansas border (Branson) and the one just above it (Pomme de Terre Lake) spawned tornados - an F3 was reported in Hermitage, MO, Hickory County, Pomme de Terre area.  [My relatives live at Pomme de Terre, and Carson's Corner, a little collection of grocery/bait shop and boat storage on a neighborhood corner, was heavily damaged by the F3 that just skirted my relatives' house - this was the corner of the neighborhood street my mother used to live on.  My relatives gave a visual report of the damage.]  Meanwhile, the long-lifer cell is almost off the screen by now.

Midnight and the squall line is still intact as well as some supercells, though they're obviously starting to wind down here.  The long-lifer cell can no longer be seen on this radar screen - however, it didn't dissipate until close to sunrise in Indiana, so at this time, it's still going strong up there.
