   ...THERE IS A MARGINAL RISK OF SEVERE THUNDERSTORMS ACROSS PARTS OF   
   THE NORTHWEST AND NORTHERN INTERMOUNTAIN REGION...   
      
   ...SUMMARY...   
   Sporadic severe wind gusts may accompany low-topped convection   
   across parts of the Northwest and northern Intermountain region this   
   morning into midday.   
      
   ...Northwest/Northern Intermountain region...   
   A progressive/vigorous shortwave trough will continue to modestly   
   amplify and otherwise race east-southeastward from the   
   Washington/British Columbia border vicinity this morning to the   
   northern Plains tonight. Intense deep-tropospheric flow (highlighted   
   by 55-85 kt at 700 mb) will accompany this wave, yielding widespread   
   high winds across much of the Northwest to the northern Great   
   Plains.   
      
   Low-topped convection, occasionally capable of lightning and   
   semi-organized line segments, will continue in association with the   
   east/southeastward-advancing cold front, with convection potentially   
   expanding by late morning towards the Snake River Plain/Yellowstone   
   vicinity and potentially other parts of the northeast Great Basin by   
   afternoon. Surface-based instability will be very limited, but some   
   convectively enhanced wind gusts may occur.
