    Mesoscale Discussion 1273
    NWS Storm Prediction Center Norman OK
    0456 PM CDT Fri Aug 10 2018

    Areas affected...Portions of the Southern Plains and Mid
    Missouri/Mississippi Valleys

    Concerning...Severe potential...Watch unlikely

    Valid 102156Z - 110030Z

    Probability of Watch Issuance...5 percent

    SUMMARY...Thunderstorms continue to develop along/near a surface
    boundary and an upper-level trough axis. Strong wind gusts are
    possible.

    DISCUSSION...Scattered pulse thunderstorms continue to develop
    across this region in the vicinity of a surface boundary and
    upper-level trough axis. Storms are forming in a moderately buoyant
    environment (1500-2500 J/kg), but without strong shear and flow
    aloft, a pulse storm mode should continue as outflow from
    dissipating storms will help generate new storms. Strong daytime
    heating has destabilized lower-levels and DCAPE of 1000+ J/kg
    indicate the potential for strong wind gusts. Some severe wind
    reports have already occurred in Oklahoma and the wind threat should
    continue until around sunset when activity is likely to decrease.
    The convection should remain unorganized and the overall severe wind
    threat is limited/isolated, therefore, a watch is unlikely.
