   ...NO THUNDERSTORM AREAS FORECAST...   
      
   ...SUMMARY...   
   Thunderstorm probabilities across the U.S. appear less than 10   
   percent for Thursday through Thursday night.   
      
   ...Discussion...   
   Models indicate that mid/upper ridging will build inland of the   
   Pacific coast, across the Sierra Nevada through the Canadian Rockies   
   and western Prairies, through this period.  As this occurs, a series   
   of short wave perturbations emerging from evolving large-scale   
   upstream troughing are forecast to approach the British   
   Columbia/Pacific Northwest, within deep-layer southwesterly flow.   
   Continuing low/mid-level moisture return is likely to support   
   another round of precipitation with an inland migrating baroclinic   
   wave.  However, beneath relatively warm mid/upper levels, saturating   
   thermodynamic profiles appear unlikely to become supportive of   
   thunderstorm development.   
      
   Meanwhile, an inland migrating short wave trough, preceding the   
   building ridge, is forecast to dig across the Great Basin and   
   Rockies, through the south central Great Plains and lower   
   Mississippi Valley by late Thursday night, as a much more prominent   
   short wave trough pivoting southwest of Hudson Bay progresses across   
   the international border into the Upper Midwest.  Beneath a   
   confluent regime in the wake of the latter perturbation, it appears   
   that another cold surface ridge will begin building across the   
   international border through the northern Great Plains and upper   
   Mississippi Valley.  In advance of the perturbation emerging from   
   the West, a weak developing lee surface low may be maintained across   
   the Red River and lower Mississippi Valleys, while perhaps another   
   weak wave develops along a remnant preceding frontal zone across the   
   northwestern Gulf Basin.  However, models indicate that western Gulf   
   boundary-layer modification and inland moisture return will be quite   
   limited, with little potential for destabilization supportive of an   
   appreciable risk for thunderstorm activity.
