    Areas affected...portons of northern Missouri

    Concerning...Tornado Watch 210...

    Valid 170158Z - 170330Z

    The severe weather threat for Tornado Watch 210 continues.

    SUMMARY...A few severe gusts may still occur with an MCS across
    northern MO over the next few hours. Isolated severe hail remains
    possible and a tornado cannot be ruled out.

    DISCUSSION...Multicells and supercells have grown upscale into a
    southward propagating MCS. A strengthening LLJ is fostering
    low-level moisture convergence/WAA with this MCS, aiding in its
    persistence this evening. Given over 2000 J/kg MLCAPE residing ahead
    of the MCS, a few severe gusts may still occur over the next few
    hours, before boundary layer stabilization limits wind potential. A
    few instances of severe hail could also briefly occur with the
    stronger storm cores. A tornado still cannot be ruled out, either
    with merging supercell structures, or a resultant embedded
    mesovortex.
