    Areas affected...Southwest Minnesota...northwest Iowa...and far
    northeast Nebraska

    Concerning...Severe potential...Watch likely=20

    Valid 022252Z - 030015Z

    Probability of Watch Issuance...95 percent

    SUMMARY...Severe thunderstorms ongoing in South Dakota will likely
    spread east into central and southern Minnesota, and possibly far
    northern Iowa and far northeast Nebraska, in the next few hours.
    Watch issuance is expected soon.

    DISCUSSION...A band severe thunderstorms ongoing across eastern SD
    has a history of producing several severe wind gusts, including a
    gust to 90 mph. Southward development of this line is also noted in
    recent radar trends. Downstream, some lingering inhibition is noted
    across southern MN, and MLCAPE generally decreases with eastward
    extent. However, the presence of a well-established cold pool within
    the MCS and 35-40 knots of effective shear will likely compensate
    for the modest thermodynamic environment and support the potential
    for further strong/severe storms downstream through the evening
    hours. Watch issuance is expected soon to address this concern.
