    Mesoscale Discussion 0908
    NWS Storm Prediction Center Norman OK
    0325 PM CDT Wed Jun 27 2018

    Areas affected...Northern Minnesota

    Concerning...Severe potential...Watch unlikely

    Valid 272025Z - 272200Z

    Probability of Watch Issuance...20 percent

    SUMMARY...A few strong to severe storms are expected this evening.
    These storms will be capable of producing large hail and damaging
    winds.

    DISCUSSION...A cluster of storms has developed in far northern
    Minnesota this afternoon. While the best convergence and forcing
    from the mid-level vorticity max will be further north, there may be
    enough convergence along the front and enough influence from the
    passing upper wave to trigger a few storms further south along the
    front. Effective shear of 40 to 50 kts and MLCAPE around 1500 J/kg
    per 20Z RAP mesoanalysis support supercells as the primary storm
    mode. Given the straight hodograph, a few storm splits are possible
    as well. Considering the limited storm coverage and marginal threat
    from any storms that develop, a severe thunderstorm watch is not
    anticipated at this time.
