   Valid 210100Z - 211200Z

   ...NO SEVERE THUNDERSTORM AREAS FORECAST...

   ...SUMMARY...
   A few lighting flashes remain possible with showers across parts of
   the Northwest this evening. Isolated thunderstorms may occur late
   tonight across portions of the lower Mississippi Valley/ArkLaTex
   region.

   ...01z Update...

   Numerous showers continue along the cyclonic side of the digging jet
   this evening across western WA/OR. While 00z sounding from UIL
   exhibited around 300 J/kg SBCAPE, seemingly more than enough for
   lightning discharge, very few flashes have been observed with this
   activity. Will maintain low thunder probabilities for this region
   for this evening.

   LLJ is expected to slowly strengthen tonight across east TX into the
   lower MS Valley. Buoyancy remains weak within this corridor early
   this evening, but continued moistening should eventually lead to
   adequate instability for elevated convection late tonight.
