   ...THERE IS A MARGINAL RISK OF SEVERE THUNDERSTORMS ACROSS THE   
   PACIFIC NORTHWEST...   
      
   ...SUMMARY...   
   Sporadic severe wind gusts may accompany isolated thunderstorms   
   across parts of the Pacific Northwest tonight.   
      
   ...Pacific Northwest...   
   A vigorous lead shortwave trough will steadily amplify today and   
   reach the coastal Pacific Northwest tonight. This will be   
   accompanied by a strong deep-layer wind field, highlighted by 90+ kt   
   winds at 500 mb and 50-80 kt winds within the lowest 1-3 km AGL.   
   This will be as Pacific moisture also steadily increases tonight in   
   tandem with the inland-advancing cold front. Low-topped convection   
   is expected to accompany the front, initially approaching the   
   Washington coast by late evening, and then more interior areas   
   overnight/early Wednesday. Surface-based buoyancy will remain   
   meager, but very strong gradient winds will shift from the southwest   
   to west-northwest as the front passes. Sporadic lightning flashes   
   and strong to severe-caliber wind gusts may accompany the passage of   
   this low-topped convective line, with the most intense low-level   
   winds/convective influences expected to peak during the overnight   
   and early morning hours of Wednesday.
