...NO SEVERE THUNDERSTORM AREAS FORECAST...

...SUMMARY...
Thunderstorms will be possible across parts of the Pacific Northwest
on Wednesday. Organized severe thunderstorms currently appear
unlikely.

...Synopsis and Discussion...
A large-scale upper trough will advance inland across the Pacific
Northwest on Wednesday. Cool mid-level temperatures and strong
large-scale ascent associated with the upper trough may support
sufficient but weak instability and the maintenance of a low-topped
band of thunderstorms. This activity should be ongoing along/near
the coast of WA/OR/northern CA at the start of the period early
Wednesday morning. Strong flow/shear is forecast at low/mid levels,
which would conditionally support organized convection. However,
surface-based instability is currently forecast to remain very weak,
which may tend to limit the overall severe threat along/near the
coast. Have therefore refrained from including low severe
probabilities at this time. The potential for isolated thunderstorms
may continue inland for portions of the higher terrain of WA/OR and
northern CA through the period as the upper trough continues
eastward.
