    Areas affected...eastern Iowa...southern Wisconsin

    Concerning...Severe Thunderstorm Watch 377...

    Valid 141645Z - 141845Z

    The severe weather threat for Severe Thunderstorm Watch 377
    continues.

    SUMMARY...The threat for isolated strong gusts or marginal hail
    continues mainly from northeast Iowa into southwest Wisconsin. It is
    unclear if another watch will be needed in the short term.

    DISCUSSION...A north-south oriented band of storms continues
    eastward across the watch and is now crossing the MS River. This
    activity is associated with the leading warm advection ahead of the
    midlevel wave, with veered low-level winds across central IA feeding instability eastward.=20

    Objective analysis shows less instability ahead of the system
    compared to farther west, but continued theta-e advection and areas
    of filtered sunshine may aid destabilization enough for some of this
    activity to become severe. While an additional watch is not
    anticipated in the near term downstream of this ongoing line, trends
    will continue to be monitored for strengthening.
