Areas affected...Southern Nebraska...northern and western Kansas

Concerning...Severe Thunderstorm Watch 192...

Valid 192312Z - 200115Z

The severe weather threat for Severe Thunderstorm Watch 192
continues.

SUMMARY...Severe threat continues across Severe Thunderstorm Watch
0192. Large hail will likely be the main threat along with isolated
damaging wind gusts.

DISCUSSION...Multicell clusters are in progress across much of the
area under Severe Thunderstorm Watch 0192. Stronger effective bulk
shear values are present in western Kansas, where occasional
supercell structures have been observed. Deep-layer and low-level
shear decrease with eastward extent, suggesting that storms will
remain multicellular and outflow dominant in eastern portions of the
watch and perhaps points east. 

CAPE of 500+ J/Kg in the -10 to -30 C layer suggests that large hail
will remain a concern, while a relatively well-mixed boundary layer
should promote strong evaporative cooling with an associated risk
for isolated damaging wind gusts with the more intense storms.
