Areas affected...Western into central Nebraska

Concerning...Severe Thunderstorm Watch 440...

Valid 202333Z - 210100Z

The severe weather threat for Severe Thunderstorm Watch 440
continues.

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
hail.

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.
