   ...DISCUSSION...   
   Medium-range model guidance initially shows a pattern featuring an   
   upper ridge over the central CONUS and trough along the West Coast,   
   transitioning to a more progressive flow regime and lowering heights   
   across the Great Plains during the Thursday-Saturday (D5-D7) period.   
   The inland-moving West Coast trough will potentially yield isolated   
   to scattered thunderstorms on Wednesday into early Thursday over   
   portions of southern and central CA and perhaps a localized risk for   
   a couple of stronger thunderstorms.  Details concerning this   
   convective scenario and overall magnitude of severe risk preclude   
   severe highlights.  Farther east, some moisture return northward   
   into the southern Great Plains and MS Valley through Friday will   
   likely be modulated by frontal advancements during the latter part   
   of extended period.
