I personally feel like what "junk" convection there is... will be moving rapidly out of the way tomorrow morning, possibly faster than the NAM shows. Also, with the storms closer to I-20 to our west running into capping as they head eastward later tonight, they will likely weaken. A lot of the high resolution, proprietary models that are usually accurate... show this well... and the SPC WRF has suggested this also. In these low amplitude events with a fast upper jet... MCS complexes often also move faster than the synoptic models show. I think most of the overnight stuff stays north of US 278/west of I-65... if even affecting Alabama at all... and then clears the LLJ axis by mid morning or so. There may actually be some mid-level subsidence behind the junk.... that would help break holes in the clouds.
