    Mesoscale Discussion 0973

    Areas affected...TX Panhandle

    Concerning...Severe potential...Watch possible=20

    Valid 252048Z - 252315Z

    Probability of Watch Issuance...40 percent

    SUMMARY...Convective Initiation along a frontal zone appears
    increasingly likely between 4-7pm CDT (21-00z). Large hail appears
    to be the primary threat, although the risk for severe gusts will
    increase during the evening.

    DISCUSSION...Visible-satellite imagery shows a gradual clumping of
    cumulus along a front draped from southwest to northeast across the
    TX Panhandle. A patch of cirrus over eastern NM appears associated
    with the leading edge of appreciable large-scale ascent from a
    Desert Southwest upper trough. As continued heating of a
    moist/destabilizing boundary layer occurs this this afternoon,
    expecting additional erosion of convective inhibition along the
    boundary. Modifying the 18z Amarillo raob for lower 80s deg F
    temperatures and lower 60s dewpoints, yields around 2400 J/kg MLCAPE
    and minimal MLCINH (-35 J/kg).=20=20

    Models continue to vary regarding timing/coverage of storm
    development within this mesoscale corridor. However, cloud trends
    and forecaster experience imply at least isolated to widely
    scattered storm development over the next 3 or so hours. Depending
    on timing/coverage of developing storms, a severe thunderstorm watch
    will be considered.
