   Valid 201630Z - 211200Z

   ...NO SEVERE THUNDERSTORM AREAS FORECAST...

   ...SUMMARY...
   A few lighting flashes will be possible with showers across parts of
   the Northwest today. Isolated thunderstorms may occur tonight across
   portions of the lower Mississippi Valley/ArkLaTex region.

   ...Pacific Northwest...
   Water vapor imagery shows an upper trough digging toward the WA/OR
   coast.  Cold temperatures aloft and strong onshore flow will pose a
   risk of isolated lightning flashes throughout the forecast period in
   this area.  More diurnally-driven thunderstorms are possible farther
   east over portions of eastern WA/OR and northern ID as the steeper
   lapse rates overspread the region.

   ...Lower MS Valley...
   Southerly low-level winds are forecast to strengthen tonight over
   the Arklatex region, helping to transport Gulf moisture northward
   and slowly destabilize the region.  Enhanced warm-advection and lift
   may lead to a few elevated thunderstorms after 06z. No severe storms
   are forecast.
