    Mesoscale Discussion 1161
    NWS Storm Prediction Center Norman OK
    0751 PM CDT Wed Jul 25 2018

    Areas affected...Eastern Nebraska and western Iowa

    Concerning...Severe potential...Watch unlikely

    Valid 260051Z - 260215Z

    Probability of Watch Issuance...20 percent

    SUMMARY...Several storms are developing along a southward moving
    cold front in eastern Nebraska. Isolated large hail and damaging
    winds are possible.

    DISCUSSION...Storms have developed in an area of increased
    convergence along a southward moving cold front in eastern Nebraska.
    The 00Z OAX sounding shows MLCAPE around 1100 J/kg with around 40
    knots of effective shear. This combination of buoyancy and shear
    will support at least a few organized storms, however, the longevity
    of this threat will be limited as surface-based CINH increases with
    the loss of daytime heating. Isolated large hail and damaging winds
    will be the primary threat for the next few hours.
