    Mesoscale Discussion 2199

    Areas affected...portions of the northern Florida Peninsula

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

    Valid 261822Z - 261915Z

    Probability of Watch Issuance...5 percent

    SUMMARY...A damaging gust or two is possible this afternoon. The
    severe threat should be sparse at best, and a WW issuance is not
    expected.

    DISCUSSION...A loosely organized line of multicells continues to
    gradually progress eastward across the northern FL Peninsula amid
    weak tropospheric flow. Given weak vertical shear, storms are
    expected to remain loosely organized, joined only by a singular cold
    pool. These storms are preceded by a heated boundary layer, where
    surface temperatures are reaching 90 F amid mid 70s F dewpoints,
    contributing up to 3500 J/kg SBCAPE (per 18Z mesoanalysis). With
    precipitable water values also exceeding 2 inches, water-loaded
    downdrafts should be common with the stronger storms, and a damaging
    gust or two may occur. However, the severe threat should remain
    sparse and a WW issuance is not anticipated.
