    Areas affected...portions of central and southern Florida

    Concerning...Tornado Watch 6...

    Valid 092348Z - 100115Z

    The severe weather threat for Tornado Watch 6 continues.

    SUMMARY...Ongoing QLCS will likely persist into this evening. Strong
    wind profiles will support continued storm organization with a risk
    for damaging gusts and isolated tornadoes. Local extension of WW6 or
    a new small watch may be needed farther south.

    DISCUSSION...As of 2345, the environment ahead of the ongoing QLCS
    over central Florida remains moderately unstable and strongly
    sheared. This should continue to support organized storms over
    south-central Florida into this evening. A few stronger elements
    have been noted within the broader QLCS with the potential for
    damaging gusts owing to the strong background wind fields. 0-1km srh
    of 300-400 m2/s2 from area VADS also suggest isolated tornadoes will
    remain possible with the more organized parts of the QLCS.

    Farther south, large-scale ascent will gradually weaken as the upper
    trough lifts away to the north through the evening resulting in more
    veered surface flow. However, relatively strong shear will likely
    remain in place into parts of South Florida. At least some severe
    risk may persist for a few hours tonight. A local extension of WW6
    or a new small weather watch may be needed to cover the remainder of
    the severe risk before storms begin to weaken and move offshore
    overnight.
