    Areas affected...Northern OK and southeast KS

    Concerning...Severe potential...Watch possible=20

    Valid 160622Z - 160715Z

    Probability of Watch Issuance...40 percent

    SUMMARY...Isolated severe storms may develop east-northeast across
    parts of northern OK into southeast KS through the pre-dawn hours.
    Large hail appears to be the most likely hazard.

    DISCUSSION...Elevated storms gradually deepened into north-central
    OK for about an hour, but appeared to plateau over the past 15
    minutes. This activity seems to be forced by lower-level warm
    theta-e advection (greater mean mixing ratios sampled by the 00Z FWD
    sounding relative to OUN) and mid-level height falls downstream of
    the vigorous shortwave trough over southeast CO. Elevated buoyancy
    and favorable southwesterly speed shear will support a threat for at
    least marginally severe hail if cells can sustain mid-level
    rotation.=20

    Primary concern is whether this activity might further deepen and
    acquire low-level rotation. MLCIN at present appears sufficiently
    robust to likely mitigate that potential in the near-term. But with
    further moistening from the south-southwest coupled with adequate
    cooling around 700 mb, there is conditional potential for a storm or
    two to become more surface-based in character. While the probability
    of this appears low, should it occur, all hazards would be possible.
