    Mesoscale Discussion 0813

    Areas affected...Parts of west/southwest TX

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

    Valid 211902Z - 212130Z

    Probability of Watch Issuance...20 percent

    SUMMARY...Strong to locally severe storms will be possible through
    the afternoon.

    DISCUSSION...A small supercell has recently developed to the
    northeast of Midland. With generally weak deep-layer flow noted in
    regional VWPs, the relative organization of this cell is likely due
    to locally backed winds and enhanced shear/SRH in the vicinity of a differential heating/baroclinic zone draped from north to east of
    Midland. This cell and any other cell that can mature within this
    zone may continue to move southeastward along the boundary, with
    moderate MLCAPE supporting a threat of large hail. Localized strong
    to severe gusts may also occur.=20

    Additional storms have recently developed near and east/northeast of
    Fort Stockton. Deep-layer shear is weaker in this region compared to
    areas farther north near the boundary, but MLCAPE of near/above 2000
    J/kg will support at least transient robust updrafts, with a threat
    of hail and localized strong to severe gusts.
