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

....SUMMARY...
Severe thunderstorms are not expected on Sunday.

....Discussion...
Progressive westerlies will persist over the CONUS on Sunday. The
next in a series of shortwave troughs will move inland over the
Pacific Northwest. Steepening lapse rates and weak buoyancy may
allow for isolated thunderstorms Sunday late afternoon through
Sunday night. Severe thunderstorms are not expected. Elsewhere, no
thunderstorms are expected as high pressure and continental
trajectories prevail from the Rockies eastward.
