...Discussion from SFOFWFMTR...

Slight (up to 5%) chances for isolated  thunderstorms continue in
the North Bay through Saturday morning. Onshore flow reduces
slightly through the weekend, compressing the marine layer slightly
and starting a slight warming and drying trend that lasts into the
early work week. Onshore flow increases in the mid week, getting
back to the cooler conditions and improving humidities.


...Discussion from SFOFWFEKA...

An upper low off the coast of central California has brought
near-normal temperatures and higher RHs to the area. Isolated to
scattered thunderstorms are possible Friday afternoon and evening.
Friday, storms shift southeast with the highest  confidence in
Trinity, eastern Mendocino, and northern Lake.  Isolated storms are
still possible outside these areas. Gusty and  erratic outflow winds
up to 50 mph and heavy downpours are  possible with the strongest
thunderstorm cells. Thunder chances  diminish for the weekend.
