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

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

....Synopsis and Discussion...
Thunderstorm potential is expected to remain quite low Sunday across
a large majority of the CONUS, with one or two possible exceptions.
An upper trough, with associated mid/upper-level jet, is forecast to
gradually amplify over British Columbia and the Pacific Northwest
through the period. Mid-level temperatures should gradually cool
while lapse rates aloft steepen as this amplification occurs.
Low-topped convection may eventually develop offshore Sunday night
and spread across parts of coastal/northwest WA. Latest NAM/RAP
forecast soundings suggest some chance for updrafts to extend deep
enough to support charge separation and occasional lightning
flashes.

A lightning flash or two also cannot be ruled out across parts of
northern CA through the day as weak MUCAPE develops with diurnal
heating. But with weak forcing aloft, overall thunderstorm coverage
across this area should remain below 10%.
