Areas affected...Nebraska Panhandle

Concerning...Severe Thunderstorm Watch 586...

Valid 160713Z - 160845Z

The severe weather threat for Severe Thunderstorm Watch 586
continues.

SUMMARY...Thunderstorms continue to move southeast out of eastern
Wyoming and into/across portions of the Nebraska Panhandle. The
threat for hail and gusty winds will continue for another couple of
hours.

DISCUSSION...Thunderstorms continue to move southeast from eastern
Wyoming into and across the Nebraska Panhandle. These thunderstorms
are slightly offset to the east-northeast from the best corridor of
instability, being supported by warm-air advection originating
within the corridor of better moisture and instability. The airmass
feeding these thunderstorms has resulted in most-unstable CAPE
values around 1000 J/kg and deep-layer shear around 50-60 knots.
Given the organized nature of the ongoing thunderstorms, the
potential for severe hail and gusty winds will continue for the next
few hours before instability diminishes sufficiently -- and
inhibition increases sufficiently -- to weaken overall thunderstorm
intensity.
