    Mesoscale Discussion 1002

    Areas affected...portions of the eastern Texas Panhandle into
    western and central Oklahoma

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

    Valid 061817Z - 061945Z

    Probability of Watch Issuance...5 percent

    SUMMARY...Widely scattered thunderstorms may pose a low-end risk for
    isolated strong to occasionally damaging wind gusts, small hail, and
    a landspout or two.

    DISCUSSION...Latest surface analysis depicts a surface low west of
    the Oklahoma City Metro, downstream of a mid-level closed low/MCV.
    More prevalent cloud cover is tempering diurnal
    heating/destabilization across portions of this area compared to
    areas farther south, but guidance still suggests 1000 to locally
    1500 J/kg MLCAPE will be present by peak heating this afternoon.
    This is expected to support widely scattered thunderstorm
    development this afternoon from the eastern Texas Panhandle into western/central Oklahoma. Deep-layer flow is also weaker across this
    region, with effective shear analyzed at 20-25 kts or less. While
    this should largely inhibit updraft/storm organization, high PWAT
    contents (1.6 inches or greater per latest objective analysis) may
    promote occasional strong wind gusts with water-loaded downbursts
    and perhaps an instance or two of damaging wind gusts. Enhanced
    surface vertical vorticity in the vicinity of the aforementioned
    surface low and increasing 0-3 km CAPE through the afternoon will
    also foster a risk for a landspout or two. Lastly, small to perhaps
    marginally severe hail may accompany the most robust updrafts. Watch
    issuance is not expected given the limited magnitude/coverage of the
    severe threat.
