    Areas affected...central to south-central Texas

    Concerning...Severe Thunderstorm Watch 232...233...

    Valid 200133Z - 200400Z

    The severe weather threat for Severe Thunderstorm Watch 232, 233
    continues.

    SUMMARY...A storm complex may consolidate and shift south/southeast
    across south-central Texas, with continued threat of locally
    damaging winds and marginal hail.

    DISCUSSION...Storms have consolidated into a SW-NE oriented line
    roughly from Gillespie into Bell/Falls Counties, with recent
    propagation to the southeast. Given the robust moisture and
    instability in place, along with southeasterly low-level winds into
    the complex, it appears likely these storms will maintain intensity
    for a few more hours as they move across the Austin area, and
    possibly close to San Antonio later this evening. Gusts at or above
    50 mph will be possible, along with hail at or above 1.00" diameter.

    Farther west, other strong cells are noted along the same aggregate
    outflow boundary, from Val Verde into Edwards Counties. The 00Z DRT
    sounding does indicate capping above 850 mb, though not particularly
    strong, and an MCS appears less likely than farther east.
