    Areas affected...eastern Minnesota...western/central Wisconsin

    Concerning...Heavy snow=20

    Valid 100112Z - 100415Z

    SUMMARY...Heavy snow to continue through the evening with occasional
    1"/hr rates.

    DISCUSSION...Heavy to moderate snow continues to be reported across
    portions of eastern MN into central WI as of 01z. The surface low
    continues to shift south and eastward, currently located over
    southern MN. 750-850 mb frontogenesis is maximized across far
    eastern MN into portions of central WI. 00z sounding from MPX shows
    a nearly saturated dendritic growth zone. Moist profiles and
    continued frontal support will continue to bring potential for heavy
    bands with 1"/hr rates over the next few hours. As the surface low
    continues to shift south and east, rates will decrease through the
    late evening/overnight.

    Areas affected...portions of southern South Carolina and far eastern
    Georgia

    Concerning...Severe Thunderstorm Watch 660...

    Valid 062300Z - 070000Z

    The severe weather threat for Severe Thunderstorm Watch 660
    continues.

    SUMMARY...Isolated damaging wind gusts and marginally severe hail
    remain possible across portions of Severe Thunderstorm Watch 660,
    but the overall severe risk is gradually diminishing.

    DISCUSSION...Latest objective analysis indicates an increase in
    convective inhibition to the south of ongoing convection across southern/eastern South Carolina where surface temperatures have
    fallen into the 80s F amid widespread cloud cover, outflow from
    prior convection, and waning diurnal heating. This has resulted in a
    gradual weakening of ongoing convection, as noted via recent
    lighting trends, and a gradual decrease in the overall severe risk.
    While this risk will continue to decrease over the next 1-2 hours,
    isolated damaging wind gusts and perhaps an instance of marginally
    severe hail cannot be ruled out with the more robust cores in the
    meantime.
