   Areas affected...west-central into south-central Alabama

   Concerning...Severe potential...Watch possible 

   Valid 262046Z - 262215Z

   Probability of Watch Issuance...40 percent

   SUMMARY...The need for an additional severe thunderstorm watch is
   uncertain.  At least a localized damaging wind risk will spread into
   Alabama late this afternoon into the early evening.

   DISCUSSION...A linear thunderstorm cluster currently extends from
   I-20 in east-central MS southward into southern MS, and it is moving
   east around 35 mph.  The airmass ahead of the storms has warmed into
   the upper 80s to lower 90s with dewpoints ranging from the upper 60s
   to lower 70s.  Although the 850-300 mb mean wind is moderate in
   strength, steepened 0-3 km lapse rates (7-8 deg C/km) amidst a high
   PW airmass (approaching 2 inches) will favor sporadic surges with
   the linear band and more intense water-loaded downdrafts.  As a
   result, at least localized/isolated 50-65 mph gusts capable of wind
   damage are forecast to eventually spread east of Severe Thunderstorm
   Watch #330.  The overall coverage of damaging gusts is uncertain and
   convective trends will be monitored regarding the need for an
   additional small severe thunderstorm watch.
