    Areas affected...portions of north Texas

    Concerning...Tornado Watch 149...

    Valid 200310Z - 200415Z

    The severe weather threat for Tornado Watch 149 continues.

    SUMMARY...The supercell tornado threat continues across southern
    parts of Tornado Watch 149. A brief, short-term uptick in tornado
    potential is possible with supercells merging with a baroclinic
    boundary.

    DISCUSSION...Three supercells are currently tracking northeastward
    across portions of north TX, west of the DFW metroplex. The Parker
    County supercell has a history of tornadoes, and tornado potential
    will continue with both of these storms over the next few hours. In
    the next 1-2 hours, these storms are poised to merge with a
    baroclinic boundary, which has encouraged other storms to merge into
    an MCS. With the boundary merger, a localized, brief uptick in
    tornado potential may be realized, and a strong tornado may occur.
    Thereafter, the storms will merge into the MCS and either become
    embedded supercells, or LEWPs/bowing segments, with some tornado
    threat persisting, though severe gusts will also be a concern.
