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

    Valid 070713Z - 070945Z

    Probability of Watch Issuance...20 percent

    SUMMARY...The potential for briefly intensifying storms posing the
    risk for a tornado or locally strong surface gusts likely will
    continue into the 3-5 AM CDT time frame. The risk still appears low
    and isolated enough that a severe weather watch is not necessary,
    but trends are being monitored.

    DISCUSSION...There has been little change during the past few hours,
    despite the continuing presence of capping layers aloft, convection
    persists along a slow moving front and a pre-frontal wind confluence
    zone slowly shifting eastward across southeastern Alabama and the
    western Florida Panhandle. There remain continuing attempts at more
    discrete deep convective development ahead of the low-level
    confluence zone, which currently appears to narrowly precede the
    surface front across areas near/west of Fort Walton Beach, before
    intersection the front (or conglomerate outflow) near/northeast of
    Crestview.

    Embedded within a narrow pre-frontal plume of seasonably moist
    boundary-layer air (including surface dew points around 70 F, and
    characterized by CAPE up to around 1000 J/kg), and strong shear
    (including sizable clockwise-curved low-level hodographs beneath
    30-40 kt southerly flow around 850 mb), weak rotation remains
    evident within cells along and ahead of the confluent zone. It
    appears that this may be coinciding with a weak frontal wave
    developing inland, northeastward across southeastern Alabama, during
    the next few hours. And potential for one or two of these vortices
    to briefly intensify to tornadic strength probably will continue
    across the Panama City FL and Dothan AL into Albany GA vicinities
    through 09-11Z.
