Areas affected...Portions of northern KS and southern NE

Concerning...Severe Thunderstorm Watch 311...

Valid 280714Z - 280815Z

The severe weather threat for Severe Thunderstorm Watch 311
continues.

SUMMARY...Mainly a strong to locally severe wind gust threat
persists early this morning. Downstream watch issuance into
northeastern Kansas and southeastern Nebraska will probably not be
needed.

DISCUSSION...Strong outbound velocities have recently been noted
from the KUEX radar with a small but well organized bowing line of
storms across north-central KS and south-central NE. The
semi-discrete storms in a warm advection regime that had earlier
been ahead of the line have generally been absorbed within the past
hour. With a linear mode now prevalent, strong to locally severe
wind gusts should be the main threat through the early morning
hours. This wind threat may be somewhat greater along/near the NE/KS
border along an instability gradient. A 35-45 kt south-southwesterly
low-level jet over the central Plains should peak in the next couple
of hours before slowly weakening. Given that the overall wind threat
with ongoing storms is expected to remain relatively confined in
both areal extent and time, current thoughts are that a downstream
watch will probably not be needed.
