    Areas affected...portions of northern into central Texas

    Concerning...Severe Thunderstorm Watch 13...

    Valid 030033Z - 030200Z

    The severe weather threat for Severe Thunderstorm Watch 13
    continues.

    SUMMARY...The severe threat continues across northern portions of
    Severe Thunderstorm Watch 13 over northern to central Texas.
    Damaging gusts and large hail remain the primary concerns, though a
    tornado cannot be ruled out, especially with stronger QLCS
    circulations.

    DISCUSSION...Strong thunderstorms are merging into a singular squall
    line across portions of northern into central TX as large-scale
    ascent continues to overspread the southern Plains. MRMS mosaic
    radar imagery had displayed possible severe hail with the earlier
    discrete storm modes, with a tornado also reported in southwestern
    Haskell County, TX in the past hour. While a couple instances of
    severe hail could still occur with the stronger storm cores,
    damaging gusts may become a relatively greater threat this evening
    given the transition to more linear storm modes.=20

    KDYX radar data has also shown brief instances of strong low-level
    rotation embedded within the maturing QLCS. Deep-layer is modest
    (i.e. 30-40 kts of effective bulk shear per 00Z mesoanalysis).
    However the mesoanalysis also shows 200 m2/s2 of effective SRH, and
    the FWS VAD shows over 300 m2/s2 0-1 km SRH with enlarged hodograph
    curvature. Since the deep-layer shear vectors are also oriented
    roughly normal to the convective line, a QLCS tornado cannot be
    ruled out this evening.
