    Areas affected...Portions of western into north-central AR

    Concerning...Severe Thunderstorm Watch 137...

    Valid 040322Z - 040445Z

    The severe weather threat for Severe Thunderstorm Watch 137
    continues.

    SUMMARY...A focused corridor of 60-80 mph severe gusts appears
    likely in the next hour or two across parts of western into
    north-central Arkansas.

    DISCUSSION...A cluster of storms crossing from eastern OK into
    western AR has recently formed into a small bowing complex. The ASOS
    at Fort Smith AR observed a 74 mph wind gust at 0253Z, and multiple
    reports of wind damage have been received. 50-70+ kt outbound
    velocities have been noted with this bow from the KSRX radar. Latest
    tracking indicates this activity is moving quickly northeastward
    around 50 kt along an instability/DCAPE gradient. The presence of
    moderate to strong instability to the south of a front, steep
    mid-level lapse rates, and 35-40 kt of deep-layer shear all suggest
    that the bow will maintain its intensity as it moves northeastward
    into north-central AR. Given the fast storm motion and rather strong
    velocities noted on radar, widespread 60-80 mph wind gusts appear
    likely in the next hour or two in association with this bowing
    complex.
