   The severe weather threat for Tornado Watch 722 continues.

   SUMMARY...Severe squall line will propagate across Alabama late this
   evening.

   DISCUSSION...Severe QLCS is propagating steadily east, in response
   to a strongly dynamic trough that is ejecting across the lower MS
   Valley. This linear MCS has surged 100-150mi ahead of the synoptic
   front, with the leading edge of the squall line now roughly
   extending along the AL/MS border. Intense LLJ has aided some
   northward destabilization, with lower 60s surface dew points noted
   to near the TN/AL border. Damaging winds can be expected with this
   MCS, along with some risk for tornadoes, especially with embedded
   supercells. This line is expected to advance across the remainder of
   ww722 into eastern AL after 07z.
