..there is a marginal risk of severe thunderstorms for parts of northern California and southwestern
Numerous showers and isolated thunderstorms are expected Saturday
across parts of the West Coast. A couple of storms may produce
locally damaging winds or a brief tornado across northern California
and southwest Oregon from late morning to mid-afternoon.
A potent middle-level trough over the eastern Pacific will move ashore from
northern California to Washington...dampening as it penetrates inland across the
northwest. Attendant surface cyclone should track from the Pacific
northwest coast towards the southern Canadian rockies with a cold front sweeping
east across the northwest.
..nrn California to southwestern Oregon...
Cool middle-level temperatures associated with the trough will likely support
sporadic charge separation with the strongest convective
elements...mainly from late morning through mid-afternoon. Despite
dampening of the trough...initially intense low/mid-level winds
/characterized by 700 mb flow at or above 60 knots/ will favor enlarged
hodographs and rather strong deep-layer shear. Buoyancy will remain
meager...SBCAPE at or below 500 j/kg...with limited surface insolation. But
given the strength of the wind fields...locally severe wind gusts
and even a brief tornado appear possible. By late day...increasingly
veered/diminishing winds will curtail the marginal severe threat.
