   Areas affected...Portions of Kansas and far northern Oklahoma

   Concerning...Severe Thunderstorm Watch 332...

   Valid 152258Z - 160000Z

   The severe weather threat for Severe Thunderstorm Watch 332

   SUMMARY...Congealing severe thunderstorms will accelerate
   east/southeast across Kansas this evening, with a continued threat
   of damaging wind gusts, a few of which could be significant.

   DISCUSSION...Several clusters of severe thunderstorms, with a few
   embedded mesoscale vortices, are evolving generally southeastward
   this evening. The overall evolution appears to suggest upscale
   growth into a bowing complex stretching from Clay County southward
   to Marion County as of 2250Z. Additionally, low-level
   confluence/warm advection is enhancing storm propagation to the west
   towards Rice County (noted in the recent appearance of several ZDR
   columns and expansion of low-level hydrometeor size sorting
   signatures). Reflectivity, velocity, and dual-pol data also suggest
   a surge or rear-inflow drying/winds pushing across Rice County. With
   storm-relative inflow bolstered by south/southeasterly winds of
   15-20 kt and strong instability ahead of the organizing complex,
   storms will likely continue to accelerate east/southeastward, with
   the potential for one or more swaths of damaging winds across
   southern/eastern Kansas. Indeed, a few significant severe gusts
   remain possible. As such, an extension and/or replacement of Watch
   332 will likely be coordinated within the hour.
