   Areas affected...Western/southern Nebraska and western Kansas

   Concerning...Severe Thunderstorm Watch 389...390...

   Valid 210429Z - 210600Z

   The severe weather threat for Severe Thunderstorm Watch 389, 390
   continues.

   SUMMARY...Overall severe-weather potential continues to diminish
   in/near Severe Thunderstorm Watches 389/390, with a lingering risk
   mainly across northwest Kansas. Watch 389 will likely expire by/at
   05Z.

   DISCUSSION...A linearly organized band of storms continues to settle
   south-southeastward across northwest Kansas, with the stronger
   updrafts embedded within the westernmost portion of the line just
   south of I-70 and Goodland/Colby areas as of 1015 pm MDT. Cloud tops
   have tended to gradually warm and the advancing cluster should
   continue to encounter increasing boundary layer inhibition and
   lesser buoyancy with southward extent. Thus, the severe-weather
   potential should continue to trend increasingly marginal over the
   next 1-2 hours, and an additional Watch issuance or extension is not
   expected.

   Farther north, additional upscale quasi-linear growth could occur
   with multiple clusters ongoing across south-central Nebraska. While
   a localized severe thunderstorm cannot be entirely ruled out,
   increasingly stable nocturnally/convectively influenced inflow
   should keep the severe potential limited.
