   Areas affected...Northeast LA...Southern/central MS

   Concerning...Severe potential...Watch possible 

   Valid 290046Z - 290215Z

   Probability of Watch Issuance...40 percent

   SUMMARY...At least an isolated severe threat will continue this
   evening with thunderstorms along the cold front. If storms continue
   to increase in coverage and intensity, watch issuance is possible.

   DISCUSSION...A small cluster of storms across north-central LA has
   intensified over the last 30 minutes. This convection has developed
   along an eastward-moving cold front. The environment remains
   relatively warm/moist ahead of the front, and 00Z soundings from
   LCH/LIX/JAN depict weak-to-moderate instability and more than
   sufficient deep-layer flow/shear for storm organization. These
   soundings also depict a capping inversion just below 700 mb,
   suggesting that forced ascent along the cold front will continue to
   be necessary for storm initiation and maintenance. 

   With the primary large-scale ascent expected to remain north of the
   region, the magnitude and longevity of the severe threat across
   northeast LA into southern MS remain uncertain, but watch issuance
   is possible if convection continues to increase in coverage and
   intensity. Regardless of watch issuance, at least isolated instances
   of severe hail/wind will be possible for at least a few hours this
   evening.
