    Areas affected...central portions of the Florida Panhandle

    Concerning...Tornado Watch 685...

    Valid 261620Z - 261815Z

    The severe weather threat for Tornado Watch 685 continues.

    SUMMARY...Local risk for brief tornadoes will continue -- with
    greatest short-term potential over central portions of the Florida
    Panhandle.

    DISCUSSION...Latest surface analysis reveals a nearly stationary
    north-south trough -- acting as a pseudo warm front and, as such,
    source of enhanced low-level vorticity -- extending from the
    Franklin/Gulf County vicinity on the Florida Coast, northward across
    far western Georgia and into the southern Appalachians. This
    boundary reflects the discontinuity between the moist/tropical
    airmass to the east, and the continental airmass to the west.=20 Several/continued brief low-level spin-ups have been observed over
    the past couple of hours within this zone, and expect this local
    enhancement of tornado potential to continue over the next couple of
    hours, given increasingly favorably low-level flow and the nearly
    stationary character of this north-south boundary.
