Got on a couple strong storms in west-central IL near Macomb. No tornado potential with these, but still some decent storm structure:
The second storm, which was more isolated, seemed to go up on the outflow boundary of the first, over northeasterly surface outflow winds from the first storm. The upper winds were from the southwest, a combination which 1) stretched out the storm giving it an LP look (though I would not call it a supercell) and 2) causing the rainshafts to be very slanted. Both of these features can be seen in this picture:

This picture, my first try at a photomerge panorama, is too wide to imbed, so to see it please click the link above.
