    Mesoscale Discussion 1604

    Areas affected...portions of Central and South Florida

    Concerning...Severe potential...Watch unlikely

    Valid 121914Z - 122115Z

    Probability of Watch Issuance...5 percent

    SUMMARY...Some risk for isolated damaging wind gusts is spreading
    southward into Central Florida. A conditional risk for isolated
    damaging wind gusts and large hail exists farther south across South
    Florida.

    DISCUSSION...An ongoing cluster of loosely organized thunderstorms
    has continued to spread southward across portions of Central Florida
    over the past 1-2 hours and has recently produced a measured 41 mph
    wind gust in the vicinity of Titusville along the Atlantic Coast.
    Despite weak deep-layer flow/shear, the environment south of this
    convection remains favorable for isolated damaging wind gusts, with
    steep low-level lapse rates, rich moisture, and moderate to strong
    instability in place.

    Farther south, a developing Cu field is noted across South Florida.
    Latest high-res guidance continues to suggest that an isolated storm
    or two may develop along the sea breeze over the next couple of
    hours. Locally greater moisture and buoyancy are noted across this
    area, with up to 3500 J/kg MLCAPE depicted by objective analysis.
    Coupled with cooler mid-level temperatures and steeper mid-level
    lapse rates (-9.5 C at 500 mb and 7-7.5 C/km, respectively, sampled
    by the 12z MFL observed sounding) compared to areas farther north,
    this would support a conditional threat for isolated damaging wind
    gusts and large hail (perhaps to half-dollar size) with any storm
    that does form in this environment.

    Given the isolated nature of these threats, watch issuance appears
    unlikely at this time.
