Mesoscale Discussion 0027
   NWS Storm Prediction Center Norman OK
   0908 AM CST Sat Jan 19 2019

   Areas affected...southeast Mississippi and southwest through central
   Alabama

   Concerning...Severe potential...Watch possible 

   Valid 191508Z - 191715Z

   Probability of Watch Issuance...60 percent

   SUMMARY...Threat for damaging wind and isolated tornadoes is
   expected to develop eastward through southwest and central Alabama
   this morning into the afternoon. Trends are being monitored for a
   possible WW east of WW 0001.

   DISCUSSION...As of mid morning a broken band of thunderstorms
   extends from extreme east central MS southwest into southeast LA. A
   few organized structures including bowing segments and embedded mini
   supercells persist within the line. Surface low will continue east
   through the TN Valley this afternoon with associated downstream
   strong low-level jet maintaining modest theta-e advection with low
   60s dewpoints contributing to around 500 J/kg MLCAPE. The band of
   convection will likely persist as it advances east within this zone
   of ascent and weak destabilization. VWP data show very impressive
   wind profiles with 60+ kt 0-6 km shear and large hodographs along
   the low-level jet corridor. This high shear/low cape environment
   will likely continue to support occasional embedded organized
   structures next several hours with damaging wind and isolated
   tornadoes the main threat.
