    Areas affected...portions of southeastern Texas

    Concerning...Severe potential...Watch possible=20

    Valid 051818Z - 051915Z

    Probability of Watch Issuance...40 percent

    SUMMARY...An increase in localized severe potential is evident with
    an intensifying supercell. Severe wind and hail are the main
    threats, though a tornado could also occur.

    DISCUSSION...MRMS mosaic radar imagery depicts a deepening supercell
    updraft across Lee County, TX, with 40 dBZ echoes exceeding 50 kft
    and MESH exceeding 1.5 inches. KGRK radar data shows this supercell
    deviating to the right, toward a surface airmass with mid to upper
    70s/60s F temperatures/dewpoints and SBCAPE approaching 1000 J/kg.
    It is possible that this currently elevated supercell may become
    surface-based, allowing for this storm to ingest more buoyant
    parcels and favorable low-level shear (evident via curved low-level
    hodographs on the EWX and GRK VADs). As such, a severe hail/gust
    threat may be increasing, and a tornado cannot be ruled out.
