    Areas affected...Portions of upper Mississippi Valley

    Concerning...Severe potential...Watch unlikely=20

    Valid 072224Z - 080000Z

    Probability of Watch Issuance...5 percent

    SUMMARY...Isolated marginally severe hail and strong wind gusts are
    possible with storms in eastern Iowa, southwestern Wisconsin, and
    northwest Illinois.

    DISCUSSION...A very narrow warm sector has developed in the upper
    Mississippi Valley southeast of an occluded surface cyclone.
    Deep-layer shear is quite marginal, but a few semi-organized storms
    are possible over the next 1-3 hours. The threat should be short
    lived as the storms will likely move into outflow from storms along
    the warm front (particularly in Wisconsin). Furthermore, dewpoints
    have been mixing out over the last hour. Isolated marginally severe
    hail and strong wind gusts will be possible with this activity.
