    Mesoscale Discussion 2050

    Areas affected...North-central Nebraska...south-central South Dakota

    Concerning...Severe potential...Watch unlikely=20

    Valid 082324Z - 090030Z

    Probability of Watch Issuance...5 percent

    SUMMARY...An isolated severe gust or marginally severe hail is
    possible with the strongest storms. Activity will likely diminish
    around sunset.

    DISCUSSION...A weak area of mid-level ascent near the Black Hills
    has helped promote widely scattered storm development near a weak
    surface low in north-central Nebraska and south-central North
    Dakota. Over the past 2 hours, updrafts have generally struggled to
    maintain intensity, likely due to weak large scale support and dry
    air entrainment. However, a couple storms have showed more intense
    cores within the last 30-45 minutes. With around 2000 J/kg MLCAPE
    and 30 kts of 0-6 km shear (per KLNX VAD), an isolated severe gust
    or marginal hail is possible. MLCIN to the east should limit the
    duration of any more intense activity. Storms are likely to weaken
    by sunset.
