   Areas affected...southeast TX and western LA

   Concerning...Tornado Watch 711...

   Valid 182129Z - 182300Z

   The severe weather threat for Tornado Watch 711 continues.

   SUMMARY...A couple tornadoes are possible through early evening with
   semi-discrete warm-sector storms ahead of an eastward-moving cold
   front.

   DISCUSSION...Deep convection intensified during the past hour with
   multiple supercells ahead of a cold front marching east in Deep East
   to southeast TX. The most favorable thermodynamic/kinematic
   environmental overlap through 01Z appears to be centered on the
   Sabine Valley. Here, surface winds remain southerly amid increasing
   low-level flow from south to north. Surface temperatures within this
   corridor are approaching the low 80s from the west, with dew points
   holding in the low to mid 70s. Ongoing semi-discrete storms across
   southeast TX will have the opportunity to maintain sustained
   supercell structures. Low-topped convection over western LA might
   intensify as well, but seemingly the more probable severe threat
   should emanate from the southeast TX storms before these cells get
   undercut by the impinging cold front.
