    Areas affected...Southeast MN

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

    Valid 261853Z - 262030Z

    Probability of Watch Issuance...20 percent

    SUMMARY...Isolated damaging wind gusts remain possible with the
    small thunderstorm cluster moving into southeast Minnesota. New
    watch issuance is unlikely in the short term.

    DISCUSSION...While the earlier well-organized MCS across MN has
    mostly decayed, convection remains relatively vigorous
    west/southwest of the Twin Cities area in southeast MN. The surface
    reflection of this system is not as strong as noted earlier, though
    rather substantial pressure rises are still being noted in the
    immediate wake of the line. Limited buoyancy on the 18Z MPX suggests
    that substantial reintensification of this cluster is unlikely, but
    the relative dryness noted below 900mb may allow for some stronger
    gusts to mix to the surface, despite the notable low-level
    stability. Since the threat is expected to remain relatively limited
    in areal coverage and magnitude, short-term watch issuance is
