    Mesoscale Discussion 1032

    Areas affected...portions of the southern High Plains and central
    Great Plains

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

    Valid 082012Z - 082215Z

    Probability of Watch Issuance...20 percent

    SUMMARY...Isolated, high-based thunderstorms will pose a risk for
    large hail and damaging/severe wind gusts this through this evening.
    Watch issuance appears unlikely at this time.

    DISCUSSION...Latest surface analysis depicts a surface low located
    in southwestern Kansas, with a trailing dryline extending
    southwestward through the Texas Panhandle and into far southeastern
    New Mexico. A weak cold front/surface trough was also analyzed,
    trailing southwestward from the low into the Oklahoma Panhandle
    before extending into Colorado. Latest guidance continues to suggest
    that isolated, high-based thunderstorms will develop along/west of
    this dryline and south of the surface trough through the late
    afternoon/early evening. Recent satellite/observational data
    supports this, with deepening cumulus noted along and west of the
    dryline within the plume of steep low-level lapse rates and a
    modified 18z observed AMA sounding suggesting minimal remaining
    inhibition.

    Weak mid-level flow and effective shear (less than 20 kts per latest mesoanalysis) will largely inhibit updraft organization. Deep,
    well-mixed boundary layers west of the dryline (dewpoint depressions
    exceeding 40-50 F) and steep low-level lapse rates will promote the
    potential for isolated damaging/severe wind gusts. Despite weak
    effective shear, steep mid-level lapse rates (9+ C/km as sampled by
    the AMA/DDC/LMN 18z observed soundings) and a modest strengthening
    of upper-level flow through the evening will also support isolated
    large hail, particularly with any storm that can interact with
    greater moisture along/east of the dryline (although, low-level
    capping within the moist air mass east of the dryline will likely
    yield short longevity for any storms that cross the dryline).

    Watch issuance appears unlikely at this time owing to the
    expectations for limited storm organization and only an isolated
    severe threat.
