    Areas affected...Texas/Oklahoma Panhandles

    Concerning...Severe Thunderstorm Watch 250...

    Valid 310045Z - 310215Z

    The severe weather threat for Severe Thunderstorm Watch 250
    continues.

    SUMMARY...Storms are expected to increase in intensity within the
    western OK/TX Panhandles. Strong/severe wind gusts are the main
    threat with isolated large hail also possible.

    DISCUSSION...Updraft development has started to increase in far
    northeastern New Mexico over the last hour. Most of these storms
    have only shown modest strength. With area VAD profile showing an
    increase in low-level southeasterly winds, the expectation is for
    storm coverage and, eventually, intensity to increase as they move
    into the TX/OK Panhandles. A radar fine line feature on KAMA imagery
    has been present along the Caprock for several hours. This feature
    has shown some westward progress recently in combination with the
    low-level winds. This appears to be a subtle moisture boundary. The
    00Z AMA sounding showed very steep mid-level lapse rates (around 9
    C/km) with little MLCIN. Efficient outflow production is expected
    which will promote strong to severe wind gusts. Large hail remains a possibility, but this is expected to occur with initial updraft
    pulses and be more isolated than wind damage.
