   Concerning...Tornado Watch 677...

   Valid 210319Z - 210445Z

   The severe weather threat for Tornado Watch 677 continues.

   SUMMARY...Threat for strong wind gusts and QLCS tornadoes is
   expected to increase over the next hour.

   DISCUSSION...Recent radar imagery has shown increased eastward
   motion with the westernmost convective line along the front across
   northeast OK. This westernmost line is expected to merge with
   earlier pre-frontal convection, likely contributing to initial
   updraft intensification followed by further upscale growth. The
   initial updraft intensification could lead to instances of large
   hail while the additional upscale growth will contribute to increase
   organization of the overall convective line. After the line
   consolidates, an increased threat for strong wind gusts as well as
   embedded/QLCS tornadoes is anticipated as the line continues across
   northeast OK into far northwest AR.
