...NO SEVERE THUNDERSTORM AREAS FORECAST...

...SUMMARY...
Severe thunderstorms are not expected on Thursday or Thursday night.

...Discussion...
Isolated thunderstorms are possible, mainly on Thursday morning to
afternoon, from central CA to western OR. Embedded within a broader
upper trough initially off the West Coast, a leading shortwave
impulse should eject northeast and move inland by Thursday night.
The attendant low-level warm conveyor will be most pronounced
Thursday morning before diminishing as it separates southward in CA.
While a few lightning flashes are possible amid flimsy instability
within this regime, mid-level lapse rates will steepen in its wake
with approach of the cold core. This should focus isolated,
low-topped thunderstorms from northern CA through western OR on
Thursday afternoon. Small hail may accompany a storm in the northern
Sacramento Valley but scant buoyancy should limit severe potential.
