Areas affected...portions of western Nebraska

Concerning...Severe Thunderstorm Watch 456...

Valid 070829Z - 070930Z

The severe weather threat for Severe Thunderstorm Watch 456
continues.

SUMMARY...Locally strong gusts may persist another or so before the
severe threat diminishes with eastward extent.

DISCUSSION...An organized, likely elevated, line of convection is
expected to continue developing eastward through early morning.
Locally strong gusts may accompany this convection in the short term
as storms traverse an environment characterized by modest
instability and moderate vertical shear. A 30-40 kt southerly
low-level jet and sufficient instability will likely maintain
convection through early morning. However, low-level inhibition and
weakening instability with eastward extent should limit severe
potential beyond 09-10z. As a result, a downstream watch is not
expected once WW 456 expires at 09z.
