    Areas affected...portions of western Texas

    Concerning...Severe potential...Watch unlikely=20

    Valid 080225Z - 080330Z

    Probability of Watch Issuance...20 percent

    SUMMARY...A few severe gusts and instances of large hail are
    possible this evening with an MCS. However, the limited duration,
    areal coverage, and ongoing nature of the severe threat suggests
    that a WW issuance is unlikely.

    DISCUSSION...Multicellular clusters and supercell structures have
    grown upscale into an MCS across western Texas. This MCS continues
    to propagate eastward into a boundary layer that has yet to
    completely stabilize, with near 80F surface temperatures and 8 C/km
    low-level lapse rates (per 02Z mesoanalysis) still present, which
    will allow for efficient downward momentum transport amid
    evaporative cooling. KMAF velocity data shows strong inbound
    velocities at the 0.5 degree scan, suggesting that a strong
    downburst or a rear-inflow jet is present within the ongoing MCS.
    Severe gusts may accompany this feature, with some of the heavier
    cores still capable of producing some severe hail. However,
    low-level shear is weak (per the latest MAF VAD), and when also
    considering boundary-layer stabilization, the severe threat should
    remain limited in coverage and duration, and a WW issuance is not
    expected.
