    Areas affected...portions of south Texas

    Concerning...Severe potential...Watch likely=20

    Valid 082355Z - 090100Z

    Probability of Watch Issuance...95 percent

    SUMMARY...A new small WW will be issued shortly. A cluster of storms
    is expected to continue eastward toward the Texas coast with a risk
    for hail and damaging winds this evening.

    DISCUSSION...As of 2355 UTC, regional radar analysis showed a
    cluster of severe storms ongoing near a diffuse front/modified
    outflow boundary across portions of the Rio Grande Valley and South
    TX. Recent radar trends and CAM guidance continue to suggest upscale
    growth is likely with this cluster, and additional storms moving
    over the River in the next few hours. The environment downstream
    remains favorable for organized severe storms with moderate
    instability and deep-layer shear. While some prior convection and
    the coastal front have reduced temperatures near the immediate coast
    somewhat, robust moisture (surface dewpoints in the 70s F) and steep
    mid-level lapse rates will likely offset nocturnal stabilization
    this evening. This suggest the threat for damaging winds and hail
    may continue into the immediate coastal counties and offshore
    tonight. Given the increasing severe threat, a small WW will be
    issued shortly east of WW241.
