   ...NO SEVERE THUNDERSTORM AREAS FORECAST...

   ...SUMMARY...
   A few thunderstorms are possible along the Pacific Northwest Coast
   on Friday.

   ...Synopsis...
   A large, deep upper low will exist over the northeast Friday
   morning, and will gradually weaken as it drifts east through the
   period. Meanwhile, an upper ridge will slowly shift east from the
   Rockies into the Plains, while yet another trough pushes across the
   Pacific Northwest region late.

   Substantial northwest surface winds will maintain relatively stable
   conditions from the Plains to the East Coast, with no instability
   forecast over much of the CONUS.

   The exception will be again along the coastal counties of WA and OR,
   as strong cooling aloft occurs. Scattered low-topped convection will
   be most likely over the ocean overnight. A few thunderstorms may
   move onshore, but at this time the stronger shear farther north does
   not appear to overlap with the minimal instability required for a
   severe threat.
