    Areas affected...Eastern Texas into central Louisiana

    Concerning...Severe potential...Watch unlikely

    Valid 071742Z - 071915Z

    Probability of Watch Issuance...20 percent

    SUMMARY...A few strong to severe gusts may occur this afternoon. The
    severe threat should remain isolated overall, so a WW issuance is
    not currently anticipated.

    DISCUSSION...MRMS mosaic radar and NLDN lightning data both show a re-intensification of a thunderstorm cluster, which is gradually
    organizing into a southward-sagging MCS structure. The southwest
    flank of this MCS is beginning to interact with a relatively
    pristine airmass preceding a stalled outflow boundary remnant from
    earlier convection. Here, surface temperatures are exceeding 90 F
    amid low 70s F dewpoints, yielding over 2500 J/kg MLCAPE. While
    deep-layer shear is weak, the aforementioned buoyancy should support
    wet downbursts capable of damaging gusts, especially with cold pool
    mergers along the leading line. Given poor vertical wind shear, the
    severe threat should be isolated, with a WW issuance not currently
    expected.
