   Mesoscale Discussion 1936
   NWS Storm Prediction Center Norman OK
   0346 PM CST Wed Nov 10 2021

   Areas affected...northwestern Missouri and south-central Iowa

   Concerning...Severe Thunderstorm Watch 546...

   Valid 102146Z - 102345Z

   The severe weather threat for Severe Thunderstorm Watch 546
   continues.

   SUMMARY...Strong wind gusts remain possible this afternoon, but a
   downstream Watch is not currently anticipated.

   DISCUSSION...A line of storms that was previously surface-based and
   producing  locally strong to damaging wind gusts continues advancing
   northeastward at over 40 knots into a less favorable environment
   where lower/middle 50s dewpoints are resulting in only weak
   instability (MLCAPE less than 500 J/kg). While somewhat favorable
   deep-layer shear of 30 to 40 knots continues to support modest
   organization of the line and the potential for strong/damaging wind
   gusts, the increasingly stable boundary-layer conditions should
   continue to limit the severe threat with northeastward extent.
   Therefore, a downstream Watch is not currently anticipated.
