   The severe weather threat for Severe Thunderstorm Watch 440

   SUMMARY...Severe winds will generally become the predominant threat
   in western/central Nebraska with time as an MCS moves east. Storms
   favorably interacting with the warm front, particularly those of
   discrete mode, will still pose some risk of a tornado and large

   DISCUSSION...Storms continue to grow upscale into an MCS in western
   Nebraska. Severe winds will likely be on the increase with this
   activity--the Alliance, NE ASOS recently recorded a 70 kt gust.
   Temperatures ahead of this line of storms remain in the upper 80s to
   low 90s F and the low-level jet should increase over the next few
   hours, aiding in storm maintenance. Along the warm front, more
   discrete storms in northwest Cherry County and east of Ainsworth
   continue. These storms will pose the greatest risk for large hail
   and possibly a tornado should they interact favorably with the warm
   front. The storm east of Ainsworth produced one reported tornado so
   far. The storm has become more HP/messy in character; however, the
   mesocyclone has periodically intensified over the last couple of
   hours as well.
