    Areas affected...Portions of north FL and extreme southeast GA

    Concerning...Tornado Watch 85...

    Valid 031405Z - 031530Z

    The severe weather threat for Tornado Watch 85 continues.

    SUMMARY...An isolated damaging wind and tornado threat may continue
    across parts of north FL. A local extension in area of Tornado Watch
    85 is possible. Or, a new downstream Watch could be issued.

    DISCUSSION...A cluster/loosely organized line of convection is
    ongoing across north FL and far southeast GA this morning ahead of a
    cold front. While the 12Z sounding from JAX showed substantial capping/inhibition and visible satellite indicates some anvil
    shading, continued diurnal heating of the moist low-level airmass
    ahead of the line of thunderstorms should help gradually erode most
    of the remaining MLCIN. Weak instability will likely be sufficient
    to maintain convective structure and intensity given ample low-level
    and deep-layer shear present on recent VWPs from KJAX. With around
    200-250 m2/s2 of 0-1 km SRH present, embedded updraft rotation
    within the line should continue to pose some threat for a few
    tornadoes through the rest of the morning and perhaps into the
    afternoon, as convection spreads east-southeastward across the north
    FL Peninsula. Occasional damaging winds will also remain a concern
    as low-level lapse rates gradually steepen. A local extension in
    area of Tornado Watch 85, or a new downstream Watch, will need to be
    considered for parts of north FL.
