    Areas affected...Extreme eastern IA into northern IL and extreme
    southern WI

    Concerning...Severe Thunderstorm Watch 361...

    Valid 040024Z - 040200Z

    The severe weather threat for Severe Thunderstorm Watch 361
    continues.

    SUMMARY...Threat for severe/damaging wind and line-embedded
    tornadoes will spread northeastward this evening.

    DISCUSSION...A storm cluster with embedded circulations remains
    intense early this evening near/south of Davenport, IA. Deep-layer
    shear vectors remain favorably orthogonal with this line segment,
    with stronger cores aloft indicating the presence of embedded
    supercells within this cluster. Favorably moist and sufficiently
    unstable downstream conditions favor maintenance of this system into
    a larger portion of northwest IL. A wind gust of 81 mph was recorded
    earlier in Burlington, IA, and wind gusts of 60-80 mph remain
    possible with this intense storm cluster. Low-level flow/shear is
    strengthening ahead of the system (as noted on the KILX VWP), and
    line-embedded tornadoes will continue to be possible, given the
    presence of embedded supercell structures.=20=20

    The severe threat may eventually spread east of WW 361, and local
    expansion of the watch will continue to be possible with time this
    evening.
