    Mesoscale Discussion 0074
    NWS Storm Prediction Center Norman OK

    Areas affected...Parts of south-central into north TX

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

    Valid 141649Z - 141845Z

    Probability of Watch Issuance...20 percent

    SUMMARY...An isolated severe threat may develop into the early
    afternoon. Short-term watch issuance is considered unlikely.

    DISCUSSION...A band of thunderstorms is ongoing this morning from
    south-central into north TX, in advance of a vigorous
    mid/upper-level shortwave trough approaching the southern High
    Plains. Outflow associated with this band of storms has shown some
    acceleration this morning, which will result in eastward progression
    of the ongoing storms through early afternoon. Despite the presence
    of strong deep-layer shear, convection has remained relatively
    disorganized thus far, due to rather weak buoyancy and the
    undercutting influence of the outflow.=20

    With time, increasing ascent associated with the approaching
    shortwave trough and gradually improving buoyancy (with MLCAPE
    gradually increasing through the 500-1000 J/kg range) may allow for
    some strengthening and increased organization into early afternoon.
    Isolated supercells and/or bowing segments could evolve with time,
    posing at least a localized threat for severe hail and wind. The
    undercutting outflow may continue to limit the magnitude and
    coverage in the short term, and watch issuance is considered
    unlikely through early afternoon.=20

    An increase in the severe threat is still expected later in the
    afternoon, as storms begin to approach east TX. Parts of
    south-central TX (near the southern periphery of ongoing convection)
    will continue to be monitored for isolated supercell development
    within a somewhat more unstable environment.
