    Mesoscale Discussion 1150
    NWS Storm Prediction Center Norman OK
    0631 PM CDT Sun Jul 04 2021

    Areas affected...North-Central Minnesota and far Northwest Wisconsin

    Concerning...Severe potential...Watch possible=20

    Valid 042331Z - 050100Z

    Probability of Watch Issuance...40 percent

    SUMMARY...Isolated convective development may increase in coverage,
    posing a hail/wind threat. Watch possible.

    DISCUSSION...Regional satellite shows a developing area of cumulus
    from near International Falls, MN, southward into north-central
    portions of Minnesota. This convective development is occurring
    along a surface trough, with a concentrated area of dew point
    temperatures at or near 70 F. RAP soundings indicate the presence of
    a weak cap that is likely being breached by the zone of enhanced
    low-level moisture along with weak ascent aloft from an approaching
    mid-level short-wave trough. The broader ambient environment is
    characterized by MLCAPE near 2500 J/kg and modest effective shear
    near 20 kt.

    There remains considerable uncertainty on storm coverage and
    intensity in the next few hours. Short-term convection-allowing
    guidance suggests storms coverage may remain mostly isolated.
    However, if the aforementioned observational trends continue, the
    environment should be supportive of organized convection, favoring
    multicells, with a hail/wind threat. Thus, watch issuance remains
    possible at this time pending short-term convective trends that will
    continue to be monitored.
