   Areas affected...Western Nebraska/northwest Kansas

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

   Valid 210218Z - 210345Z

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

   SUMMARY...Severe wind/hail potential continues mostly across far
   southwest Nebraska/northwest Kansas, and to a lesser extent across
   the Nebraska Sandhills/west-central Nebraska, this evening in and
   close to Severe Thunderstorm Watches 389/390.

   DISCUSSION...Upscale quasi-linear growth has occurred across
   southwest Nebraska with a 100-mile-extensive band of storms
   continuing to spread south-southeastward from far southwest Nebraska
   into northwest Kansas. While boundary layer inhibition has begun to
   slowly increase, 80s F surface temperatures persist ahead of the
   line with MLCAPE remaining in excess of 2000 J/kg. With some
   increase noted in southeasterly low-level winds (1km) per the
   Goodland WSR-88D VWP, increased low-level storm-relative inflow will
   aid severe-storm persistence into/across far northwest Kansas in the
   short-term with severe-caliber wind gusts/wind-driven hail a
   possibility.

   Another organized but less intense linear cluster ongoing across the
   eastern Nebraska Panhandle/Cherry County at mid-evening will
   continue southeastward. While some wind/hail remains possible,
   overall storm intensity will likely be limited by increasingly
   stable inflow owing to influences of prior convection and loss of
   daytime heating.
