   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.
