....NO SEVERE THUNDERSTORM AREAS FORECAST...

....SUMMARY...
Isolated thunderstorms may occur Sunday night across parts of
coastal/northwest Washington.

....Discussion...
The upper flow field across the U.S. will continue to trend toward
an increasingly zonal configuration with time, as upper troughing
continues to shift away from the East Coast into the western
Atlantic.

At the surface, high pressure will prevail across much of the
country, along with generally dry/stable conditions.

During the second half of the period, a short-wave trough digging
southward along the British Columbia coast will reach the Pacific
Northwest.  Cold air aloft/steep lapse rates will likely yield weak
destabilization late -- largely across the western Washington
vicinity.  As such, sporadic lighting may evolve with showery
convection anticipated across this area.

Elsewhere, thunderstorms are not expected.
