   Areas affected...Portions of northern KS and southern NE

   Concerning...Severe Thunderstorm Watch 311...

   Valid 280714Z - 280815Z

   The severe weather threat for Severe Thunderstorm Watch 311
   continues.

   SUMMARY...Mainly a strong to locally severe wind gust threat
   persists early this morning. Downstream watch issuance into
   northeastern Kansas and southeastern Nebraska will probably not be
   needed.

   DISCUSSION...Strong outbound velocities have recently been noted
   from the KUEX radar with a small but well organized bowing line of
   storms across north-central KS and south-central NE. The
   semi-discrete storms in a warm advection regime that had earlier
   been ahead of the line have generally been absorbed within the past
   hour. With a linear mode now prevalent, strong to locally severe
   wind gusts should be the main threat through the early morning
   hours. This wind threat may be somewhat greater along/near the NE/KS
   border along an instability gradient. A 35-45 kt south-southwesterly
   low-level jet over the central Plains should peak in the next couple
   of hours before slowly weakening. Given that the overall wind threat
   with ongoing storms is expected to remain relatively confined in
   both areal extent and time, current thoughts are that a downstream
   watch will probably not be needed.
