    Areas affected...South-central and southeast NE

    Concerning...Tornado Watch 114...

    Valid 160822Z - 160915Z

    The severe weather threat for Tornado Watch 114 continues.

    SUMMARY...QLCS tornadoes and severe wind gusts should remain the
    primary threats with a north-northeast moving line of storms over
    south-central NE.

    DISCUSSION...Numerous but generally brief, mesovortices were noted
    earlier along the north to eastern flank of a QLCS in south-central
    NE. Measured severe wind gusts up to 67 mph have been common. The
    attendant MCV centered over Dawson County appears to be advancing
    north, along with its immediate downstream deep convection arc. This orientation has become perpendicular to the low and deep-layer shear
    vector which is aligned from the south, and should move along the
    fringe of 60-61 F surface dew points. Farther southeast closer to
    the KS border, the bowing arc is closer to slightly richer surface
    dew points (62-63 F), and its orientation should favor sporadic
    transient mesovortices within 40-50 kt of south-southwesterly 0-1 km
    shear.
