    Mesoscale Discussion 0659
    NWS Storm Prediction Center Norman OK
    0158 AM CDT Thu Jun 07 2018

    Areas affected...Central KS...North-central OK

    Concerning...Severe potential...Watch possible

    Valid 070658Z - 070830Z

    Probability of Watch Issuance...60 percent

    SUMMARY...The threat for large hail and strong winds gusts will
    likely persist across central KS for the next several hours and a
    watch may be needed.

    DISCUSSION...Thunderstorms have developed rapidly along the eastern
    edge of the low-level jet over the past hour or so. In this area,
    steep mid-level lapse rates are contributing to moderate to strong
    instability and warm-air advection is lifting parcels to their LFC.

    Additionally, southeastward progressing MCS moving through northwest
    KS has begun to interact with the newly developed warm-air advection
    storms. Expectation is for this storm interact to result in
    increased forward propagation into central KS and a higher
    probability for damaging wind gusts.

    Initially disorganized cluster across southwest KS has become
    increasingly more organized over the past hour. As a result, the
    reflectivity gradient along the leading edge has become
    significantly sharper as storms have increased in strength.
    Furthermore, recent velocity data from KDDC reveals strong westerly
    winds in the wake of the system, indicative of a strong rear-inflow
    jet. MCS strengthening and maintenance is anticipated as this system
    continues eastward across south-central KS. Some development
    southward into north-central OK is possible.
