    Mesoscale Discussion 0653
    NWS Storm Prediction Center Norman OK
    0235 PM CDT Wed Jun 06 2018

    Areas affected...MUCH OF WYOMING

    Concerning...Severe potential...Watch possible

    Valid 061935Z - 062130Z

    Probability of Watch Issuance...40 percent

    SUMMARY...Severe wind gusts and large hail may accompany storms this afternoon/evening across most of Wyoming (except southwest/western
    Wyoming).

    DISCUSSION...Surface temperatures have warmed into the upper 70s and
    low 80s increasing buoyancy across most of Wyoming. Current
    satellite imagery shows building cumulus clouds are still mostly
    tied to terrain features. However, continued steepening low-level
    lapse rates and falling heights aloft associated with an approaching
    shortwave trough should help increase ascent/buoyancy and develop
    storms by 20z. Storms should eventually move off the terrain and
    form a loosely organized cluster as they move northeast. Forecast
    MLCAPE of 1500-3000 J/kg and DCAPE of 800-1500 J/kg with 30-40 kt
    bulk shear are supportive of a few storms with the potential to
    produce severe wind/hail.
