    Areas affected...Central Texas

    Concerning...Severe Thunderstorm Watch 340...

    Valid 192158Z - 200000Z

    The severe weather threat for Severe Thunderstorm Watch 340
    continues.

    SUMMARY...A severe threat is expected to continue into this evening
    with large hail and wind damage possible across parts of central
    Texas. As the severe threat moves toward the edge of weather watch,
    new watch issuance will need to be considered.

    DISCUSSION...The latest high-resolution radar imagery from San
    Angelo shows a severe convective cluster over the Texas Hill
    Country. These storms are located near a thermal axis extending
    southeastward across central Texas, where surface temperatures are
    well above 100 F. Large temperature-dewpoint spreads are resulting
    in high-based storms with damaging outflow potential. The WSR-88D
    VWP at Fort Hood has a supercell wind profile, with 0-6 km shear
    near 40 knots. This, combined with 700-500 mb lapse rates near 8.5
    C/km, will also support a large hail threat. The severe threat will
    move toward the edge of weather watch 340 over the next hour, and
    could affect areas to the east of the watch later this evening. For
    this reason, a new watch could be needed across central Texas by
    00Z.
