   The severe weather threat for Tornado Watch 721, 722 continues.

   SUMMARY...Severe threat will spread across eastern Alabama and the
   western Florida Panhandle into extreme western Georgia after
   midnight. New watch may be warranted later this morning downstream.

   DISCUSSION...An elongated QLCS, arcing roughly 500 miles, currently
   extends from middle Tennessee-central Alabama-southeast LA-northern
   Gulf of Mexico. This MCS is largely supported by a strong upper
   trough that has advanced into the lower MS Valley, and a pronounced
   LLJ that extends across AL into KY. This activity is expected to
   remain organized as it propagates downstream into an air mass that
   is adequately buoyant, but strongly sheared. Isolated damaging winds
   continue to be reported along the leading edge of the MCS, and a few
   embedded circulations are noted at times. Of note, a few pre-squall
   line supercells continue across southeast AL and the tornado
   potential appears to be a bit higher with these more isolated,
   longer-lived updrafts.

   With time, a new watch may be warranted downstream.
