    Areas affected...Northeast New Mexico...southeast Colorado...and
    portions of the Texas/Oklahoma Panhandles

    Concerning...Severe Thunderstorm Watch 181...

    Valid 172210Z - 180015Z

    The severe weather threat for Severe Thunderstorm Watch 181
    continues.

    SUMMARY...The threat for severe wind and hail will continue in the
    near term, especially across northeast New Mexico into the
    northwestern OK/TX Panhandles. The potential for severe wind may
    increase into the early evening hours.

    DISCUSSION...Latest regional radar and GOES IR trends show a few
    discrete supercells, along with severe semi-discrete clusters,
    developing along the higher terrain of northeast NM/southeast CO and
    along a dryline across far eastern NM and west TX. Sporadic severe
    wind and hail have been reported with this activity with 1 inch hail
    recently noted across eastern NM and a 51 knot convective wind gust
    reported at KLVS in northern NM.=20

    In the near term, the potential for severe wind and hail will
    continue across all of WW 181, though the corridor of highest severe
    potential will likely reside from northeast NM into the
    west/northwestern OK/TX Panhandles region. Across this area, steep
    low-level lapse rates (near 9 C/km) are overlapping with 35-45 knots
    of effective bulk shear as well as near 30 knots of 0-3 km bulk
    shear (noted in regional VWPs), which will continue to support a
    large hail threat and perhaps increase the potential for severe
    winds as discrete/semi-discrete storms gradually grow upscale this
    evening.=20

    Further to the north across southeast CO, storm motions have largely
    been slow and along the axis of initiation, and continued upscale
    growth is anticipated for the next few hours. Instances of severe
    hail are possible with any stronger updraft pulses, but weaker
    deep-layer flow amid steep 0-3 km lapse rates suggest a gradual
    eastward progression of a broken line, and and isolated severe wind
    threat, is possible as cold pools begin to consolidate.
