Areas affected...Western Nebraska

Concerning...Severe potential...Watch possible=20

Valid 282318Z - 290045Z

Probability of Watch Issuance...40 percent

SUMMARY...Multicell clusters with isolated severe outflow gusts will
be possible, but the need for a watch is uncertain.

DISCUSSION...High-based storms have developed along a surface trough
from northeast CO into the NE Panhandle. These storms are primarily
driven by surface heating/mixing, with new development expected
along convective outflows that spread eastward into the larger
buoyancy. The storms/clusters will be capable of producing
strong-severe outflow gusts in an environment with very steep
low-midlevel lapse rates and strong downdraft potential. However,
vertical shear is weak and storm organization/longevity will be
limited and the need for a watch is uncertain.
