    Mesoscale Discussion 0866

    Areas affected...west Texas

    Concerning...Severe potential...Watch unlikely

    Valid 242250Z - 250045Z

    Probability of Watch Issuance...20 percent

    SUMMARY...Isolated storms are developing over west Texas and may
    pose a risk for large hail and downburst winds. Storm coverage is
    expected to remain sparse. As a result a WW will probably not be
    needed, but trends will continue to be monitored.

    DISCUSSION...Early this evening Isolated storms are in the process
    of developing across west TX between Fort Stockton and Snyder where
    deep mixing with temperatures exceeding 100 F is occurring in
    vicinity of the dryline. Vertical shear is weak, but steep lapse
    rates, inverted-V boundary layers and moderate instability will
    support a risk for downburst winds and hail. Storms appear diurnally
    driven and should begin a weakening trend after sunset. Due to the
    expected short duration and very isolated coverage, a WW will
    probably not be needed.
