   ...NO THUNDERSTORM AREAS FORECAST...

   ...SUMMARY...
   No thunderstorms are forecast to develop across the contiguous
   United States on Friday.

   ...Synopsis...
   Upper troughing is forecast to cover the eastern CONUS early Friday
   morning, while an upper low remains centered over the Baja Peninsula
   and a belt a strong westerlies stretches from the northeast Pacific
   Ocean into the northern High Plains. The eastern CONUS upper trough
   is expected to remain progressive, quickly moving off the Eastern
   Seaboard while becoming more negatively tilted with time. A
   shortwave trough will move quickly through the westerlies, moving
   across the Pacific Northwest and northern Rockies and reaching the
   northern High Plains by early Saturday morning. At the same time,
   the upper low over Baja is expected to slowly drift eastward into
   northwest Mexico. 

   At the surface, a cold front will likely stretch from southern New
   England southwestward through the eastern Carolinas and off the
   coast of the central FL Peninsula early Friday. This front will move
   eastward/southeastward throughout the day, but limited low-level
   moisture and buoyancy preceding the front will preclude thunderstorm
   development. Stable conditions are also expected elsewhere across
   the CONUS.
