1400 UTC: Morning complex left over from the previous night.
1800 UTC: Morning complex moved east, with last vestiges east of St. Louis. Note first cell in western MO. But this one dissipated quickly.
1930 UTC: Cells already developing upstream in very unstable air mass.
2100 UTC: Pattern of discrete cells despite enough time to have started forming a line - environment ahead of prefrontal trough supported isolated supercells.
2200 UTC: Most well-developed cell, with large inflow notch, is the middle of the group of three in northeast MO. This one produced the Canton/Lima tornado.
2300 UTC: Southernmost of that group of three now has the strongest reflectivity. It later produced the Monroe City tornado.
Meanwhile, a line is forming further west along the cold front
2330 UTC: Note the storm just north of Columbia, MO. It will become important much later...
0030 UTC: Note the western appendage on the Monroe City storm (now in IL), as a new cell went up just west of it and began to merge with it.
0200 UTC: The merger now looks complete, and the old Columbia storm which had weakened now restrengthened and is rapidly catching up, almost ready to merge
0300 UTC: The old Columbia storm now appears to have a little hook. I'm not sure if this cell or the earlier merger with the Monroe City storm spawned the South Pekin F3, but it was one or the other, not the Canton/Lima cell.
