    Concerning...Severe Thunderstorm Watch 145...

    The severe weather threat for Severe Thunderstorm Watch 145

    SUMMARY...Damaging winds remain possible across northern Georgia for
    the next 1-2 hours. A gradual weakening trend is possible heading
    into the late afternoon hours.

    DISCUSSION...A few reports of wind damage have been noted across
    northern GA associated with the ongoing MCS across the northern and northeastern portion of the state. Recent reflectivity/velocity data
    from KFFC suggests that the MCS is becoming outflow dominant across north-central GA with a discernible outflow boundary outrunning the
    higher reflectivity. GOES IR imagery also points to a gradual
    weakening trend in the initial MCS as cloud tops begin to warm. A
    few stronger updraft pulses remain likely within remnants of the
    MCS, but will mainly be confined to northeast GA.=20

    To the west, a bowing segment is emerging from northeast AL into
    northwest GA and has a history of producing at least sporadic wind
    damage and severe hail across AL. This segment is expected to move
    north of the outflow boundary from the GA MCS and into a cooler,
    more stable air mass. Strong velocities noted with this line (per
    KFFC) suggests wind damage remains possible for northwest GA for the
    next hour or so, but a gradual weakening seems likely as this
    activity continues northeast.
