    Areas affected...portions of southern and central Florida

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

    Valid 161758Z - 161900Z

    Probability of Watch Issuance...20 percent

    SUMMARY...Scattered thunderstorms have developed, and will likely
    increase in coverage over parts of southern and central FL this
    afternoon. The severe risk with this initial round is uncertain,
    though sufficient buoyancy exist for isolated damaging gusts and
    hail.

    DISCUSSION...As of 1745 UTC, regional radar and satellite
    observations showed intensifying thunderstorms along a pre-frontal
    confluence axis across central FL, and along the sea breeze front in
    the eastern peninsula. Ahead of the QLCS associated with the
    upstream cold front, these storms have begun to mature, within a
    warm and unstable air mass (2000-2500 J/kg MLCAPE). Strong updrafts
    are present and likely to continue. However, vertical shear is
    modest currently, with much of central and southern FL displaced
    from the stronger mid-level flow to the northwest. Thus, these
    initial storms have shown little in the way of organization so far.
    Isolated hail will be possible given the degree of buoyancy.
    Isolated damaging gusts are also possible, especially with storms
    that cluster and can develop stronger cold pools.

    The QLCS upstream will likely continue across the eastern Gulf and
    move onto the peninsula later this afternoon into the evening. Some
    severe potential may persist with that. However, as large-scale
    ascent shifts away to the north, the QLCS may weaken overnight.
    Thus, some severe potential is apparent this afternoon, and later
    this evening, but confidence in either scenario necessitating a
    watch is low. Conditions will continue to be monitored.
