   ...NO SEVERE THUNDERSTORM AREAS FORECAST...   
      
   ...SUMMARY...   
   Isolated to widely scattered thunderstorms are possible along parts   
   of the West Coast, lower Ohio/mid-Mississippi Valley, and lower   
   Great Lakes regions. Severe weather is not anticipated.   
      
   ...Synopsis...   
   A pair of successive shortwave troughs are expected to progress   
   north-northeastward on Wednesday into Thursday morning. The initial,   
   weaker perturbation will move from the mid-Mississippi Valley into   
   the upper Ohio Valley. Some thunderstorm potential will exist ahead   
   of this feature within a warm advection regime in lower Michigan   
   into northeast Ohio and northwest Pennsylvania.   
      
   Farther west, a more potent shortwave will move from the lower   
   Colorado Valley/western Great Basin into the central Plains by   
   Thursday morning. In its wake, general troughing will in the West.   
   Cold temperatures aloft will foster potential for isolated   
   thunderstorms along much of the West Coast. A few lightning flashes   
   may also occur ahead of the progressing shortwave trough in the   
   eastern Great Basin. However, ample cloud cover and cool/cold   
   temperatures will keep such activity quite sparse.   
      
   A surface low will develop late in the period in the central High   
   Plains and shift into eastern Kansas/western Missouri by Thursday   
   morning. Mid-level ascent and warm/moist advection will gradually   
   increase from the Mississippi/Ohio confluence into parts of the   
   lower Ohio Valley. There is some signal from both global and   
   regional CAM guidance for development very late in the period near   
   the Mississippi/Ohio confluence. Farther north and east, capping may   
   prevail given more nebulous forcing. Severe weather is not   
   anticipated with any of the activity in these regions.
