   Mesoscale Discussion 0842
   NWS Storm Prediction Center Norman OK
   0810 PM CDT Thu May 25 2017

   Areas affected...Portions of central Kansas

   Concerning...Severe Thunderstorm Watch 267...

   Valid 260110Z - 260215Z

   The severe weather threat for Severe Thunderstorm Watch 267
   continues.

   SUMMARY...Thunderstorms will continue to progress east/southeast
   this evening, with a few more instances of large hail and/or
   damaging winds possible. However, the overall threat should further
   wane over the next few hours. Downstream watch issuance is not
   anticipated but trends will continue to be monitored.

   DISCUSSION...Recent regional WSR-88D data indicate the overall
   organization of a pair of severe storms has trended downward over
   the last hour or so. Reflectivity data have suggested a transition
   to a more diffuse cluster mode, versus the previous
   southeastward-propagating supercell/bowing structures. This trend is
   likely to continue, as storms move into an environment characterized
   by increasing convective inhibition. Furthermore, warm-advection
   related cells ahead of the main cores are likely stabilizing the
   downstream environment further. As such, downstream watch issuance
   is not anticipated as storms approach the southeastern extent of
   Watch 267. However, a few cores could occasionally intensify over
   the next 2-3 hours, with large hail and damaging winds remaining
   possible (as evidenced by upshear propagation/development over
   southeastern Gove County recently).
