    Areas affected...far south-central Nebraska and north-central Kansas

    Concerning...Severe Thunderstorm Watch 360...

    Valid 100645Z - 100745Z

    The severe weather threat for Severe Thunderstorm Watch 360
    continues.

    SUMMARY...Local severe risk persists across a small, southwestern
    portion of WW 360.

    DISCUSSION...Latest radar loop shows that convection has vacated
    eastern portions of WW 360, moving east-southeastward into
    southeastern Nebraska and northeastern Kansas (into WW 363). As
    such, severe risk has largely ended across WW 360. The exception to
    this exists across southwestern portions of the watch, ahead of
    storms moving southeastward across southwestern Nebraska. A
    corridor of instability is evident at this time across northern
    Kansas -- including southern portions of WW 360, and with a 40 kt
    southwesterly low-level jet providing warm advection-induced ascent
    across this area, storms on the southern flank of the Nebraska
    cluster may spread into the watch in the next hour or so, along with local/attendant risk for damaging wind gusts. If this convection
    persists as expected, a local extension in time for a small portion
    of the watch may need to be considered, beyond the scheduled 10/08Z
    expiration time.
