    Areas affected...north-central into northeast Kansas and
    south-central into southeast Nebraska

    Concerning...Severe Thunderstorm Watch 211...

    Valid 170315Z - 170515Z

    The severe weather threat for Severe Thunderstorm Watch 211
    continues.

    SUMMARY...The threat for significant damaging gusts of 70-85 mph
    persist this evening.

    DISCUSSION...A relatively compact but intense bow echo continues to
    produce significant severe gusts as it moves across northern KS and
    southern NE. Multiple gusts of 70-80+ mph have been measured over
    the past few hours, most recently 82 mph at Holdrege NE. Notably,
    these gusts have occurred even after cool northeast surface winds
    were seen at these stations. As such, at least the leading edge of
    the southward-moving outflow ahead of this bow does not appear to be
    mitigating severe potential.=20

    With a 50 kt low-level jet ahead of this activity and ample
    instability, the damaging wind threat is expected to persist across
    WW 211, possibly reaching the MO River later this evening.
