Areas affected...Southwest NE into western KS and parts of eastern
CO

Concerning...Severe Thunderstorm Watch 413...

Valid 140432Z - 140600Z

The severe weather threat for Severe Thunderstorm Watch 413
continues.

SUMMARY...Some severe threat could persist into the early overnight.

DISCUSSION...A loosely organized storm cluster recently produced a
57 kt gust in Ogalalla, NE. Moderate downstream buoyancy and
modestly favorable deep-layer shear will continue to support some
severe-wind threat in the short term as this system moves across
southwest NE and extreme northwest KS. The longevity of the severe
threat is uncertain due to increasing MLCINH with time. Some
backbuilding along the trailing outflow also remains possible into
far northeast CO.=20

Farther south, a storm cluster has shown some signs of
intensification across southeast CO. With strong downstream buoyancy
(MLCAPE greater than 3000 J/kg) and the nocturnal low-level jet
forecast to become focused into southwest KS overnight, there is
some potential for this cluster to intensify with time, and
potentially pose some threat for severe wind and hail. However, this
potential remains uncertain due to the competing influences of
increasing CINH and generally modest deep-layer flow/shear. Trends
will be monitored for an uptick in severe potential and the need for
watch issuance downstream of this cluster.
