    Areas affected...southeast GA

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

    Valid 011732Z - 012000Z

    Probability of Watch Issuance...20 percent

    SUMMARY...Widely scattered thunderstorms will continue to develop
    this afternoon over southeast GA. Isolated strong to locally severe
    gusts are possible and will be potentially capable of wind damage.=20
    Peak gusts will likely range from 50-60 mph.

    DISCUSSION...Visible satellite/radar composite shows developing
    thunderstorms between Macon and Savannah where temperatures have
    risen into the lower 90s with mid 70s dewpoints. Surface analysis
    indicates a narrow plume of richer low-level moisture (implied by
    surface dewpoint observations) extends from north FL northward into
    southeast GA. High PW (1.75-2.00 inches) will favor water-loaded
    downdrafts with the more intense cores. The nose of an 80-kt 300-mb
    speed max centered on the KY/TN border is moving south-southeastward
    into the area (50-kt isotach overspreading east-central GA). This
    stronger high-level flow will act to marginally organize the
    developing thunderstorm activity into a southward-moving cluster
    with time. The cold pool aggregation will probably help focus the
    localized risk for strong damaging gusts this afternoon.
