    Areas affected...eastern New Mexico and portions of northwest Texas

    Concerning...Severe Thunderstorm Watch 235...

    Valid 250034Z - 250130Z

    The severe weather threat for Severe Thunderstorm Watch 235
    continues.

    SUMMARY...Severe threat continues within WW235. There is a
    conditional risk across the far southern portion of the watch for
    large hail, gusty winds, and a tornado or two into the evening.

    DISCUSSION...A storm ongoing near Tucumcari, NM has produced 2 inch
    hail along with significant wind gusts as high as 75 mph in the last
    hour. Additional thunderstorm development is occurring along
    developing outflow emanating from this storm across south-central
    Quay and Curry Counties. Expect additional development further south
    in the next couple of hours with potential for gusty winds and large
    hail.

    Further south in WW235, uncertainty grows with a conditional threat
    through the evening. Recently, an area of more pronounced cumulus
    development was ongoing across Chaves County. Surface observations
    indicate that mixing has been occurring with the surface dew point
    dropping into the upper 40s from the early afternoon mid 50s.
    Visible satellite has shown many failed attempts at initiation
    within this area and further west along the dryline. One weak cell
    was able to initiate but has struggled to intensify. Day Cloud Phase Distinction satellite imagery continues to show deepening cu with
    evidence of glaciation. As the low level jet intensifies this
    evening, moisture should increase along with low-level flow. If a
    cell can successfully initiate in this regime and track eastward, a
    conditional threat of large hail, damaging winds, and a tornado will
    be possible through the evening.
