    Concerning...Severe Thunderstorm Watch 461...462...

    Valid 242210Z - 250015Z

    The severe weather threat for Severe Thunderstorm Watch 461, 462
    continues.

    SUMMARY...Damaging winds, and perhaps some hail, are expected with thunderstorms this evening.

    DISCUSSION...Early-day thunderstorm clusters that spread over MN/WI
    have generated substantial convective outflow that has surged south
    into northern IL. Thunderstorms are gradually increasing just north
    of this boundary near the WI/IL border which should aid a slow
    southward movement this evening. Additionally, two strong/severe
    line segments have evolved over eastern IA and this activity is
    moving southeast at roughly 35kt. Given the strength of this
    convection, it appears organized thunderstorm clusters will spread
    across the remainder of northern IL toward southern Lake MI over the
    next several hours. Strongest winds will likely be noted with any northeast-southwest oriented bow-type structures along the line.
