   ...NO THUNDERSTORM AREAS FORECAST...

   ...SUMMARY...
   Thunderstorms are not expected on Friday.

   ...Synopsis...
   An upper trough will extend along the Eastern Seaboard early Friday
   morning before continuing eastward into the western Atlantic Ocean
   throughout the day. In the wake of this upper trough, expansive high
   surface pressure associated with a cold, dry, and stable continental
   air mass will shift southeastward, covering much of the southern
   Plains, Southeast and OH Valley by the end of the period.
   Consequently, thunderstorms are not anticipated across the central
   or eastern CONUS. 

   An isolated lightning flash or two is possible along or just off the
   southern CA coast as a closed upper low approaches the region early
   Saturday morning. Current expectation is for thunderstorm coverage
   before 12Z Saturday to remain less than 10% with higher coverage
   anticipated later Saturday morning and into the afternoon (see the
   Day 3 Convective Outlook for more details).
