    Areas affected...Northwestern/north-central Ohio

    Concerning...Severe Thunderstorm Watch 26...

    Valid 192039Z - 192215Z

    The severe weather threat for Severe Thunderstorm Watch 26
    continues.

    SUMMARY...Strong/severe wind gusts are most likely in parts of
    northern Ohio over the next couple of hours.

    DISCUSSION...Strong mixing has lowered dewpoints across southern
    Ohio to the low/mid 30s F. Farther north, a longer duration of cloud
    cover has sheltered the area from mixing. Dewpoints in northern Ohio
    have remained in the low/mid 40s F. Observational trends indicate
    that the strongest portion of the frontal convection has been where
    dewpoints are in the mid 40s F. Though forcing from the shortwave
    trough will remain moderate/strong, it appears that the greatest
    threat for strong/severe wind gusts will be confined to where these
    greater dewpoints are in northern Ohio.

    Areas affected...Southeastern Nebraska and Northeastern Kansas

    Concerning...Snow Squall=20

    Valid 182244Z - 190045Z

    SUMMARY...Dangerous snow squall moving southeast with low visibility
    and moderate to heavy snowfall.

    DISCUSSION...A snow squall is in progress with moderate to heavy
    snowfall and visibility less than 1/4 mi reported in Hastings,NE and
    Grand Island, NE. This squall continues to move south east and may
    have reached peak intensity, with some uncertainty in what the
    duration will be given it's location behind the front and low
    agreement in hi-res guidance in forecast and duration. Rapid drop in
    visibility is expected with this squall due to moderate to heavy
    snowfall in combination with strong winds and blowing snow from snow
    pack on the ground.
