    Areas affected...portions of central and eastern Oklahoma

    Concerning...Severe Thunderstorm Watch 192...

    Valid 082215Z - 090015Z

    The severe weather threat for Severe Thunderstorm Watch 192
    continues.

    SUMMARY...Threat for large to very large hail continues across
    portions of central and eastern Oklahoma.

    DISCUSSION...Supercells continue to increase in coverage along the
    cold front sagging southward into central/eastern Oklahoma. Hail up
    to 2.75 inches and winds gusts to 60 mph have been reported with the
    northern cells in Osage County. Supercells will continue eastward in
    the Oklahoma City Metro and Tulsa Metro this evening. The
    environment downstream remains very favorable for large hail (1.5-2+
    inches) with steep low to mid-level lapse rates and moderate MLCAPE.
    This has been well sampled in the 20z RAOB from OUN, where lapse
    rates around 7 C/km extend through the profile and 45 kts of 0-6 km
    shear. Given dew point depressions around 20-25 F, the threat for
    damaging wind will continue, possibly increasing into the evening as
    cells cluster and tend to grow upscale.
