    Areas affected...parts of central and eastern Oklahoma and north
    central Texas

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

    Valid 061957Z - 062230Z

    Probability of Watch Issuance...60 percent

    SUMMARY...Isolated to widely scattered strong to severe thunderstorm development may gradually initiate through 3-6 PM CST. This may
    include supercells accompanied by large hail, and at least some risk
    for tornadoes.

    DISCUSSION...Though the dryline may remain relatively diffuse, it
    appears to be coming at least a bit better defined near the I-35
    corridor of Oklahoma, southward into portions of western North
    Texas. Low-level convergence along it is generally weak, and the
    primary short wave perturbation emerging from the southern Great
    Basin is tending to slowly pivot northeast of the Colorado Rockies
    into the central Great Plains. However, aided by a corridor of
    low-level moistening near the interface of the stronger
    boundary-layer warming, notable destabilization is ongoing as
    mid-level inhibition erodes.

    This is evident in 18Z raobs from Lamont, Norman and Fort Worth, and
    it appears that, with continued low-level warm advection, isolated
    to widely scattered thunderstorms may begin to initiate during the
    next few hours. Within strongly sheared, 40-50 kt
    south-southwesterly deep-layer mean flow, the evolution of a few
    supercells appears possible, which should tend to take on a more
    prominent easterly propagation as they intensify.=20=20

    Given the conditional and convective instability present, these
    storms will pose a risk for large hail and localized strong surface
    gusts. Low-level hodographs appear at least conditionally
    supportive of tornadoes. However, the extent of this potential
    remains unclear, particularly given the downstream low-level
    subsidence and drying forecast in the Rapid Refresh output,
    including forecast soundings, through early evening.
