    Mesoscale Discussion 2252
    NWS Storm Prediction Center Norman OK

    Areas affected...Parts of west-central FL

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

    Valid 072156Z - 080030Z

    Probability of Watch Issuance...20 percent

    SUMMARY...Locally damaging wind and a brief tornado are possible
    this evening.

    DISCUSSION...A storm cluster has intensified this afternoon across
    the northeast Gulf, where an offshore buoy recently reported a gust
    of 52 kt at 2050 UTC. This storm cluster appears to be accompanied
    by a midlevel vorticity maximum and surface low, as evidenced by
    rather strong pressure falls at the buoy preceding the severe gust.
    Downstream of this storm cluster, modest destabilization has
    occurred across central and southern parts of the FL Peninsula,
    along and south of a baroclinic zone draped from near/south of Tampa
    eastward to just south of Cape Canaveral.=20

    Weak lapse rates (as observed in the 18Z TBW sounding) will tend to
    limit instability across the peninsula into this evening. However,
    any organized storm structures that approach the coast, or develop
    inland near the boundary, may be able to persist within the
    favorably moist environment near and south of the baroclinic zone. A substantial increase in 0-2 km AGL flow has recently been noted in
    the KTBW VWP, which will also aid in maintenance of any organized cells/clusters, and provide sufficient effective SRH for low-level
    rotation.=20

    A brief tornado will be possible near and south of the surface
    boundary, where at least weak surface-based buoyancy will persist
    through the evening. Locally gusty/damaging winds will also be
    possible, especially with any of the stronger offshore storm
    structures as they approach the coast later this evening.
