    Areas affected...Western North-Central TX

    Concerning...Severe Thunderstorm Watch 21...

    Valid 130803Z - 130900Z

    The severe weather threat for Severe Thunderstorm Watch 21
    continues.

    SUMMARY...Corridor of greater wind damage and QLCS tornado potential
    exists across western north-central TX.

    DISCUSSION...Recent KDYX imagery has shown a sharpening of the
    convective line moving into western north-central TX. This
    sharpening is coincident with the lines interaction with slightly
    better low-level moisture and moderate southerly/southeasterly
    surface winds. Additionally, VAD wind profiles from KDYX show a
    well-defined rear-inflow jet. Interaction between this
    well-organized part of the convective line, southeasterly surface
    winds, slightly better low-level moisture, and favorable orientation
    of the storm motion to the vertical shear suggests a higher wind
    damage and QLCS tornado threat within this corridor for the next
    hour or so.
