Valid 141300Z - 151200Z

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

....SUMMARY...
Severe thunderstorms are not forecast today.

....Synopsis...
A midlevel shortwave trough will continue eastward/inland over CA
later today into tonight, and will reach the lower CO River
Valley/southern Great Basin by the end of the period.  Cooling
midlevel temperatures and steepening low-midlevel lapse rates will
support SBCAPE of 300-600 J/kg and the potential for thunderstorms
later today into early tonight across the central/northern CA coast.
There will be a low chance for weakly rotating (but sub-severe)
storms in the Sacramento/San Joaquin Valleys into the foothills of
the Sierra Nevada later this afternoon/evening.  Farther east near
the end of the period, weak buoyancy and forcing for ascent may be
sufficient for isolated lightning flashes from southeast NV into
northwest AZ, but the overall threat appears too low to add an
outlook area.
