    Areas affected...north AL...far northwest GA...far southeast TN

    Concerning...Severe Thunderstorm Watch 209...213...214...

    Valid 022003Z - 022200Z

    The severe weather threat for Severe Thunderstorm Watch 209, 213,
    214 continues.

    SUMMARY...A mix of marginal severe hail and strong to isolated
    severe gusts is expected to persist across mainly northern Alabama
    through early evening.

    DISCUSSION...Yet another line segment has consolidated, this time
    along the MS/AL border area, generally on the southern periphery of
    the scattered convective swaths over the Deep South and TN Valley.
    With low to mid 80s surface temperatures ahead of this line at peak
    mixing of the boundary layer, potential for strong to severe gusts
    (55-70 mph) should mainly spread across north AL through early
    evening. Recent surface observations from KHSV and KCBM have
    measured 48 kt gusts. Small to marginally severe hail cores will
    remain embedded within the line and in additional cells that can
    redevelop atop the large-scale convective outflows, across far north
    AL and north GA. Areas farther north-northwest in middle TN appear
    to be well stabilized.
