    Areas affected...much of western Texas

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

    Valid 241605Z - 241830Z

    Probability of Watch Issuance...95 percent

    SUMMARY...Storms capable of large, damaging hail and eventually
    damaging winds are likely to develop this afternoon from southwest
    into much of western Texas.

    DISCUSSION...Cooling aloft with a shortwave trough is already aiding
    the development of thunderstorms containing hail over Far West TX
    this morning. Substantial high clouds are currently limiting surface
    heating over much of the region, but breaks in the clouds as well as
    eventual boundary layer mixing with gusty south winds will
    accelerate warming over the next several hours.

    Surface analysis indicates the ongoing activity is just west of the
    better low-level moisture where dewpoints are in the lower 60s F.
    Despite the clouds and only modest surface warming, forecast
    soundings indicate strong instability will develop as mid and upper
    level lapse rates steepen. MLCAPE over 1500 J/kg is likely, with
    greater values where heating is stronger.

    Effective deep-layer shear of 40-50 kt as well as modest low-level
    veering with height will favor supercells for a few hours, with
    locally significant hail possible. A tornado or two is possible with
    the stronger supercells that may develop, with sufficient effective
    SRH increasing toward 200 m2/s2 by 00Z
