    Mesoscale Discussion 0073

    Areas affected...Western to central Texas

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

    Valid 140957Z - 141200Z

    Probability of Watch Issuance...20 percent

    SUMMARY...A corridor favorable for weak supercells may persist
    across portions of western to central Texas through 6 AM CST. Watch
    issuance is not expected.

    DISCUSSION...Intensification of maturing supercells is noted in
    recent MRMS and GOES imagery to the north and west of the San
    Angelo, TX area. These cells are becoming established within a
    somewhat narrow mesoscale corridor where low-level warm/moist
    advection is overriding cold pools established by prior precipitation/convection, which is maintaining MUCAPE values between approximately 500-1000 J/kg. Persistent deep-layer ascent within the
    warm air advection regime and ahead of the approaching upper wave,
    coupled with strong flow aloft (60-70 knots between 6-8 km per the
    KSJT VWP), should maintain a corridor favorable for supercell
    development. Based on recent MRMS estimates, these cells should be
    capable of producing severe hail (most likely up to 1.5 inches in
    diameter) and isolated strong to severe gusts. Undulation in the
    vertically integrated ice fields associated with the deeper
    convective cores casts some uncertainty onto the longevity of any
    individual cells, but this favorable mesoscale corridor may persist
    across the region through roughly 6 AM CST.
