    Mesoscale Discussion 1987
    NWS Storm Prediction Center Norman OK
    0637 PM CST Fri Dec 10 2021

    Areas affected...Eastern Oklahoma and western Arkansas.

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

    Valid 110037Z - 110200Z

    Probability of Watch Issuance...60 percent

    SUMMARY...A new tornado watch may be needed across portions of
    eastern Oklahoma and western Arkansas.

    DISCUSSION...Rapid storm development has occurred along the dryline
    near the Oklahoma/Arkansas border as the strong ascent overspreads
    the warm sector. These storms will likely pose a threat for large
    hail, damaging winds, and a few tornadoes as they continue east into
    the overnight hours. A new tornado watch may be needed to cover this
    threat west of watch 552.
