   Areas affected...Western/Central KS...Northwest OK

   Concerning...Severe Thunderstorm Watch 371...

   Valid 150421Z - 150615Z

   The severe weather threat for Severe Thunderstorm Watch 371
   continues.

   SUMMARY...Isolated hail/wind threat continue across western/central
   KS and northwest OK.

   DISCUSSION...An expanding corridor of convection is currently noted
   across southwestern KS/northwestern OK within a zone of focused
   low-level warm advection. Surface boundary that is draped across
   central KS into the TX Panhandle is not expected to move appreciably
   over the next several hours, and a LLJ over western OK is impinging
   on this boundary over south-central KS. This appears partly
   responsible for the recent increase in thunderstorm activity over
   the last hour. Long-lived supercell cluster that formed over CO has
   evolved into a LEWP over southwest KS. These storms are expected to
   propagate east, along the cool side of the boundary. Hail/wind
   remain possible with this activity.

   If the ongoing activity over southwestern KS continues to grow
   upscale, there may be a need to consider a new watch downstream.
