    Areas affected...Southeast ND into northeast SD and extreme
    west-central MN

    Concerning...Severe Thunderstorm Watch 476...

    Valid 100323Z - 100530Z

    The severe weather threat for Severe Thunderstorm Watch 476
    continues.

    SUMMARY...A threat for severe wind and hail will continue
    southeastward through late evening, though an eventual weakening
    trend is expected.

    DISCUSSION...A persistent cluster of storms with embedded supercell
    structures is moving southeastward across southeast ND late this
    evening. A few measured severe gusts and reports of wind damage have
    recently been noted, while MRMS hail-size estimates continue to
    occasionally exceed severe criteria. While a favorable combination
    of buoyancy and deep-layer shear is in place downstream of this
    cluster, nocturnal cooling and increasing MLCINH is expected to
    result in a gradual weakening trend by near/after midnight CDT.
    Given the forward-propagating nature of this cluster, some threat
    for severe wind and/or hail may eventually move out of WW 476 into
    parts of northeast SD and extreme west-central MN. Short-term trends
    will continue to be monitored regarding any need for downstream
    watch issuance.
