   Mesoscale Discussion 0351
   NWS Storm Prediction Center Norman OK
   1203 PM CDT Sun Apr 12 2020

   Areas affected...Portions of far northeastern LA...far southeastern
   AR...and central MS

   Concerning...Tornado Watch 106...

   Valid 121703Z - 121830Z

   The severe weather threat for Tornado Watch 106 continues.

   SUMMARY...Strong tornado potential is increasing across northeastern
   LA into central MS early this afternoon.

   DISCUSSION...Multiple tornadic circulations producing TDSs have
   recently been observed with a QLCS advancing rapidly eastward across
   north-central into northeastern LA. The VWP from KDGX (Jackson, MS)
   shows a very strongly sheared low-level wind profile. Over 80 kt of
   southwesterly flow is being estimated around 3 km AGL, with around
   70 kt of 0-3 km shear present. A corridor of greater severe
   potential, including the possibility of strong tornadoes and
   widespread damaging winds, will likely be focused through the early
   afternoon from parts of northeastern LA into central MS ahead of the
   QLCS and to the south of a northward-developing warm front. Embedded
   circulations within the line, or a supercell or two developing on
   its southwestern flank, will pose the best potential for strong
   tornadoes given the very favorable low-level shear (0-1 km SRH in
   excess of 500 m2/s2).
