    Mesoscale Discussion 1412

    Areas affected...Texas Panhandle into Western Oklahoma

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

    Valid 252048Z - 252245Z

    Probability of Watch Issuance...20 percent

    SUMMARY...Thunderstorm development appears likely in the TX
    Panhandle into W OK later this afternoon. A few isolated damaging
    wind gusts and hail reports are possible, but overall coverage of
    severe weather is expected to remain low, meaning watch issuance is
    not likely at this time.

    DISCUSSION...Visible satellite imagery shows vertical development of boundary-layer cumulus has increased over the Texas Panhandle in the
    last 1.5-2 hours, suggesting that convective initiation may be
    likely in the next hour or two. This cumulus is in the vicinity of a
    weak surface low, with surface temperatures in the upper 90s to low
    100s F, and dewpoints ranging from the upper 50s F in the northwest
    panhandle to mid 60s F near the TX/OK border, resulting in MLCAPE >
    1000 J/kg. Deep layer vertical shear is strongest in the Northern TX
    Panhandle into W OK, with values around 35 kts, decreasing with
    southwestward extent.=20

    Given the hot, dry boundary layer, and weak to modest vertical
    shear, a few isolated damaging wind gusts from thunderstorm outflow
    may be possible this afternoon into the evening. Eastward extent of
    convection is uncertain at this time, but given the better
    combination of shear and buoyancy over W OK, a few isolated hail
    reports are possible with any storms that develop. However, overall
    coverage of severe weather is expected to be low.=20

    Given the lack of support for organized convection, and uncertainty
    in eastward extent of convection with the better environment, watch
    issuance is not likely.
