   Mesoscale Discussion 0139
   NWS Storm Prediction Center Norman OK
   0808 PM CST Wed Feb 08 2023

   Areas affected...Portions of southwest into south-central MS and
   southeast LA

   Concerning...Tornado Watch 32...

   Valid 090208Z - 090345Z

   The severe weather threat for Tornado Watch 32 continues.

   SUMMARY...The risk of damaging winds and a couple mesovortex
   tornadoes should increase during the next few hours.

   DISCUSSION...Latest radar data from KPOE shows an organizing
   north-south-oriented line segment tracking east-northeastward at
   around 50 mph over far southwest MS into southeast LA. Lower/middle
   60s dewpoints should continue to yield surface-based inflow for this
   line, while 50+ kt of midlevel flow oriented oblique to the
   leading-edge gust front should favor a continued organized/linear
   mode. Additional upscale growth/storm mergers downstream along with
   a strengthening pre-frontal low-level jet should support an
   increasing risk of damaging gusts. 50-70 mph gusts (some locally
   higher) are possible with any bowing/forward-propagating segments in
   the line. In addition, favorably curved low-level hodographs (per
   DGX VWP data) could also support a couple mesovortex tornadoes --
   especially in parts of the line that become oriented more SSE-NNW.
