   Concerning...Severe Thunderstorm Watch 650...

   Valid 270001Z - 270130Z

   The severe weather threat for Severe Thunderstorm Watch 650
   continues.

   SUMMARY...The threat for severe gusts, hail, and possibly a tornado
   will continue eastward through the evening.

   DISCUSSION...A QLCS with embedded supercell structures has produced
   occasional severe wind and hail reports as it moves eastward. Recent
   VWP data from KUDX suggests the presence of a rear-inflow jet, and a
   combination of sufficient instability and rather strong deep-layer
   shear will help to maintain this QLCS as it moves eastward this
   evening. Embedded supercells will remain possible along the southern
   flank of the QLCS, with some additional development possible into
   northwest/north-central NE. 

   The threat for severe gusts will continue to accompany this QLCS as
   it moves eastward this evening, along with a threat of hail and
   possibly a tornado with any embedded supercells. The northern extent
   of the severe threat into central SD remains in question, due to
   cooler/more-stable conditions and stronger MLCINH in the wake of an
   outflow-reinforced surface front. This renders the need for a watch
   north of WW 650 uncertain, though some threat for strong to locally
   severe gusts cannot be ruled out into central SD, given the
   relatively organized nature of the QLCS.
