    Mesoscale Discussion 1609

    Areas affected...Extreme southeast MN/northeast IA...Southwest WI

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

    Valid 261812Z - 261945Z

    Probability of Watch Issuance...20 percent

    SUMMARY...Some increase in the damaging wind threat is possible this
    afternoon ahead of a convective line. Watch issuance is currently
    considered unlikely.

    DISCUSSION...At 18Z, a line of thunderstorms is gradually
    intensifying across northeast IA into southeast MN, along a remnant
    outflow from the decaying MCS across central IA. While substantial
    cloud cover is noted downstream into southwest WI, some modest heating/destabilization has occurred, especially near and south of a
    surface boundary draped from southern WI into southwest MN.=20

    Continued modest destabilization and steepening of low-level lapse
    rates may allow for an increasing damaging wind potential with this
    line as it moves northeastward. Relatively modest deep-layer
    flow/shear (as noted in KARX VWP) should keep organization
    relatively limited, so watch issuance is currently considered
    unlikely.
