   Concerning...Severe Thunderstorm Watch 181...

   Valid 292002Z - 292200Z

   The severe weather threat for Severe Thunderstorm Watch 181
   continues.

   SUMMARY...The potential for more widespread wind damage is expected
   to increase across portions of central and southern Mississippi into
   southwest Alabama over the next 2-3 hours.

   DISCUSSION...A west-to-east-oriented band of strong to severe storms
   is ongoing just south of the I-20 corridor in MS and northeast LA as
   of 20z. Occurrences of hail to 1" and thunderstorm wind damage have
   been reported in the Jackson, MS vicinity within the past hour.
   Additional elevated storms ongoing to the west of the watch area
   across northern LA are expected to merge with the predominant band
   of storms over the next hour, which should enhance overall cold pool
   strength. That process may lead to an accelerated southeastward
   motion of the convective band from central into southern MS and
   southwest AL with an attendant risk for more widespread damaging
   winds. 

   Isolated occurrences of large hail will remain possible, especially
   on the western flank of the convective system where mid-level lapse
   rates are steeper.
