   ...NO THUNDERSTORM AREAS FORECAST...

   ...SUMMARY...
   Thunderstorms are not expected across the U.S. today or tonight.

   ...DISCUSSION...
   An upper-level trough will move across the eastern U.S. today as
   another upper-level trough remains in the eastern Pacific. A
   mid-level jet associated with this system will overspread the
   Pacific Northwest tonight. Strong large-scale ascent and steep lapse
   rates will be enough for an isolated lightning strike along the
   coast of Washington late in the period. However, thunder coverage is
   not expected to reach the 10 percent threshold. Elsewhere across the
   CONUS, thunderstorms are not expected today or tonight.
