   ...NO SEVERE THUNDERSTORM AREAS FORECAST...   
      
   ...SUMMARY...   
   A few thunderstorms are possible in the Pacific Northwest on Tuesday   
   and Tuesday night.   
      
   ...Discussion...   
   As high pressure moves from the Southeast into the Atlantic, and   
   weak lee troughing develops across the High Plains, southerly return   
   flow returns across the Plains on Tuesday. Some showers may develop   
   within weak isentropic ascent across east Texas on Tuesday night,   
   but most guidance shows minimal instability until after 12Z   
   Wednesday. Therefore, thunderstorm activity is not expected.   
      
   Thunderstorms are possible in western Washington and far northwest   
   Oregon on Tuesday and Tuesday night as a strong mid-level trough   
   approaches the coast. Weak instability is expected during the   
   afternoon, but most forecast soundings suggest the equilibrium level   
   will be too low for charge separation which may keep any lightning   
   potential isolated. However, by late Tuesday night/early Wednesday,   
   as cold air aloft overspreads the region, sufficiently deep   
   instability is expected for lightning across western Washington and   
   perhaps into northwest Oregon. During this time, more frequent   
   lightning may be possible with a line of convection along the   
   surface front.
