    Mesoscale Discussion 0454
    NWS Storm Prediction Center Norman OK
    0317 PM CDT Fri Apr 26 2019

    Areas affected...Central/Southern UT

    Concerning...Severe potential...Watch unlikely

    Valid 262017Z - 262215Z

    Probability of Watch Issuance...5 percent

    SUMMARY...Isolated strong wind gusts are possible for the next
    several hours.

    DISCUSSION...Amidst filtered sunshine and deep mixing, temperatures
    have warmed into the 70s across much of central and southern UT.
    This has eroded preceding convective inhibition and allowed for the
    development of scattered thunderstorms. Instability is modest (i.e.
    MLCAPE around 500 J/kg) and much of the region is displaced south of
    the stronger flow aloft and vertical shear. Even so, unidirectional
    wind profiles support quick storm motion and the steep low-level
    lapse rates will aid in strengthening downdrafts. As such, sporadic
    instances of strong wind gusts are possible. Isolated/marginal
    nature of the severe threat will preclude the need for a watch.
