   Concerning...Tornado Watch 701...

   Valid 162110Z - 162215Z

   The severe weather threat for Tornado Watch 701 continues.

   SUMMARY...A strong convective line capable of damaging wind gusts
   and tornadoes will continue across northeast/east-central MS into
   northwest/west-central AL over the next few hours. A downstream
   watch will likely be needed across northwest/west-central AL within
   the next hour or two.

   DISCUSSION...Convective line moving through northern MS has recently
   shown increased forward motion to around 45 kt. At this speed, this
   portion of the line will likely reach the MS/AL border around 2200Z.
   Instability is expected to be modest, tempered primarily by cooler
   surface temperatures (i.e. low 70s) and warm mid-level temperatures.
   That being said, a remnant of the EML will still exist and
   deep-layer shear is expected to be very strong (60+ kt from 0-6 km).
   Additionally, the strongest part of the low-level jet will be
   focused across the region from west-central MS into middle TN. The
   conditions suggest the ongoing line should persist as it moves
   across northeast/east-central MS and into northwest/west-central AL.
   Damaging wind gusts are likely with tornadoes embedded within the
   line also possible. A Watch will likely be needed across portions of
   northwest/west-central AL within the next hour or two.
