    Mesoscale Discussion 1745

    Areas affected...Portions of northern/central WI and the U.P. of MI

    Concerning...Severe Thunderstorm Watch 556...

    Valid 280230Z - 280400Z

    The severe weather threat for Severe Thunderstorm Watch 556
    continues.

    SUMMARY...Isolated severe threat should continue to slowly diminish
    this evening.

    DISCUSSION...Outflow from multiple thunderstorm clusters has pushed
    well south of ongoing convection across northern/central WI.
    Multiple recent observations across this area show sub-severe wind
    gusts up to around 40 kt occurring. While the 00Z GRB sounding
    showed around 2000 J/kg of MLCAPE present, modifying this sounding
    for current surface observations suggests that MLCIN has
    strengthened somewhat. Tendency should be for these clusters to
    gradually become more elevated above the slowly stabilizing boundary
    layer this evening. While isolated strong to damaging winds will
    remain possible in the short term, the overall severe threat should
    continue to wane towards 04Z/11 PM CDT, which is the scheduled
    expiration of Severe Thunderstorm Watch 556.
