    Mesoscale Discussion 2163

    Areas affected...Western/northern Oklahoma and southern Kansas

    Concerning...Severe potential...Tornado Watch likely=20

    Valid 301815Z - 301945Z

    Probability of Watch Issuance...80 percent

    SUMMARY...There is an increasing threat for supercells this
    afternoon across western/north-central Oklahoma and southern Kansas.
    These storms will have a threat for large hail and a few tornadoes.

    DISCUSSION...Some type of impulse triggered some elevated
    thunderstorms across southern Kansas this morning. In the wake of
    this activity, subsidence has resulted in clearing and significant
    surface heating across western Oklahoma and southern Kansas. In
    addition, low-level moisture advection has increased dewpoints to
    64-67F ahead of the dryline as far north as Reno and Harvey Counties
    in Kansas. SPC mesoanalysis currently suggests around 1000 to 1500
    J/kg MLCAPE and minimal inhibition. Continued surface heating and
    mid-level cooling may allow for some additional destabilization
    later this afternoon. Current visible satellite shows deepening
    cumulus along the dryline from Harper County, Oklahoma to near
    Childress, TX. Expect initial strong/severe storm development near
    the triple point in northwest Oklahoma/southern Kansas where forcing
    is strongest. Eventually expect additional development southward
    along the dryline to near I-40 in Oklahoma. These storms along the
    dryline will have greater potential to remain discrete for a few
    hours given the more favorable boundary orientation. At this time,
    the most favored solution is a more linear wind/QLCS tornado threat
    along the cold front in Kansas with a more discrete hail/strong
    tornado threat associated with supercells in northern Oklahoma and
    southern Kansas. Based on current trends, a tornado watch will
    likely be needed soon.
