With a rather strong cold front, good speed shear, and some low-level directional shear, it looks like storms are a good bet and supercells a possiblity in and near southern Illinois. Moisture is an issue, but strong forcing, shear, and upper support will likely be enough to trigger strong storms anyway. Could go linear fast, though. I am thinking of heading down to around the Rend Lake or Carbondale areas to see what happens. If severe wx does occur, it will likely be in the same general area affected by last Friday's outbreak, though perhaps just a tad further east.
