...NO SEVERE THUNDERSTORM AREAS FORECAST...

...SUMMARY...
Severe thunderstorms are not expected today or tonight.

...Synopsis/Discussion...
A progressive quasi-zonal flow regime will prevail over the CONUS.
There will be limited potential for deep convection owing to the
general prevalence of high pressure and associated dry/stable
conditions.

An exception will be across parts of the coastal Pacific Northwest
where some thunderstorms will remain possible today coincident with
weak buoyancy and steep lapse rates. However, the chance for
isolated thunderstorms should diminish tonight.
