    Areas affected...portions of the southern Florida Peninsula

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

    Valid 141933Z - 142130Z

    Probability of Watch Issuance...20 percent

    SUMMARY...Scattered thunderstorms ongoing along typical sea breeze
    fronts may briefly organize with the potential for sporadic hail and
    some damaging gusts. A WW is unlikely.

    DISCUSSION...As of 1925 UTC, regional radar and satellite data
    showed scattered thunderstorms had developed and begun to mature
    along typical sea breeze boundary corridors across the southern and
    eastern FL peninsula. Strong surface heating amid upper 60s to low
    70s F surface dewpoints was supporting 1500-2000 J/kg of MLCAPE.
    While deep-layer flow is modest, easterly low-level flow and 180
    degree opposed 20-25 kt winds aloft are supporting sufficient
    deep-layer shear (25-30 kt) for organized multicells and some
    transient supercell structures. Given the storm mode and favorable thermodynamics, a few of the stronger cells appear capable of
    sporadic hail. Additionally, high PWAT content could support a few
    stronger downdrafts capable of damaging gusts.

    Current trends and recent CAM guidance suggests convection should
    increase in coverage through this afternoon across the eastern and
    southern parts of the FL Peninsula. Storms may intermittently
    strengthen and weaken with some risk for localized severe weather.
    Given overall storm organization will be transient, the severe risk
    appears isolated enough that a watch will not be needed.
