    Areas affected...Central and North Texas...Southern Oklahoma

    Concerning...Severe potential...Watch unlikely=20

    Valid 241137Z - 241400Z

    Probability of Watch Issuance...20 percent

    SUMMARY...A severe threat may continue across parts of central and
    north Texas this morning. Isolated severe gusts and hail will be the
    primary threats. The potential for weather watch issuance is low.

    DISCUSSION...Mosaic radar imagery shows a line of strong
    thunderstorms located from southern Oklahoma into north Texas, with
    a linear cluster extending southward into central Texas. The storms
    are located near a moist axis where surface dewpoints are in the mid
    to upper 60s F. Across the moist airmass, the RAP is estimating
    MLCAPE in the 1000 to 1500 J/kg range. The instability, combined
    with large-scale ascent ahead of a shortwave trough and warm
    advection are supporting the storms. In addition, the FWS WSR-88D
    VWP has 0-6 km shear has 30 to 35 knots with some directional shear
    in the low to mid-levels. This shear environment should be enough to
    continue an isolated wind-damage and hail threat. The severe threat
    may increase locally over the next hour or two, as the cells to the
    south merge with the line to the north.
