Watching the progression of ongoing activity, it seems clear that a narrow zone from the eastern Texas Panhandle into SW Oklahoma will have a chance at a slow moving, SE moving supercell this afternoon with an attendant threat of giant hail and a tornado or two. While shear is weaker than yesterday (to the point I think HP modes are more likely) — the low-level environment will be supportive of a tornado or two with a mature and dominant supercell in this region. Expect storm motions to be slow (15 mph or less) to the south and east.
