    Mesoscale Discussion 0676
    NWS Storm Prediction Center Norman OK
    0935 PM CDT Fri Jun 08 2018

    Areas affected...Portions of northeast Missouri

    Concerning...Severe potential...Watch unlikely

    Valid 090235Z - 090430Z

    Probability of Watch Issuance...5 percent

    SUMMARY...Storms that fired along a remnant outflow boundary have
    persisted over the hour or two and have shown some propensity for
    severe hail. Some continued development along any storms outflow is
    still possible with an isolated hail threat being the primary
    concern. The overall nature of the threat should be limited in
    coverage and duration. A WW is not expected.

    DISCUSSION...Over the last hour, storms in northeast Missouri have
    continued to show at least intermittently strong cores. A 1.25 hail
    report out of Grundy County occurred within the last half-hour. RAP
    analysis and WV imagery show a very weak wave that may help maintain
    storm intensity for perhaps an hour or two. Latest high-resolution
    guidance has storms declining by 04Z. However, MUCAPE values
    2000-3000 J/kg and modest deep-layer shear of around 25 kts should
    allow for a continued, isolated severe hail threat as long as storms
    can persist. A WW is not expected.
