    Areas affected...portions of the Florida Panhandle into southern
    Georgia and North Florida

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

    Valid 091711Z - 091915Z

    Probability of Watch Issuance...5 percent

    SUMMARY...At least some risk for isolated damaging wind gusts may
    persist into the afternoon from the central Florida Panhandle into
    southern Georgia and North Florida. Watch issuance is not expected.

    DISCUSSION...Latest surface analysis depicts a convectively
    reinforced surface front extending from near the Georgia coastline west-southwestward to offshore of the Emerald Coast of Florida.
    South of this surface boundary temperatures in the mid/upper-70s to
    low-80s F and dewpoints in the low/mid-70s will support around
    500-1500 J/kg MLCAPE by early this afternoon despite poor mid-level
    lapse rates (per latest mesoanalysis and the 12z JAX observed
    sounding). Strong effective bulk shear of 40-50+ kts will be
    sufficient to support organization of stronger updrafts, and PWATs
    of 1.75-1.90" across the region may support the potential for
    heavier water loading and isolated damaging wind gusts with any
    stronger cores over the next few hours, especially along and south
    of the aforementioned surface boundary. Trends will continue to be
    monitored, but watch issuance is not expected at this time owing to
    the marginal thermodynamic environment and the expectation for any
    severe risk to remain limited in magnitude and coverage.
