...Discussion from SFOFWFMTR...

Good to excellent overnight humidity recoveries continue within the
marine layer influence, which will compress to around 1000-1500 feet
on Friday as a shortwave trough moves away. Humidity recoveries
remain poor in the higher elevations, especially within the Central
Coast. Breezy onshore winds will develop each afternoon and evening
with stronger gusts expected on Sunday and Monday. Temperatures
remain near to slightly below seasonal averages through the middle
of next week.


...Discussion from SFOFWFEKA...

Chance for afternoon thunderstorms will continue today through
Friday. Storms will likely be wet, though isolated fire  starts will
still be possible with dry strikes on the periphery of rain cores.
Frequency and coverage of lightning strikes today  will generally be
less than on Wednesday. Storms will most likely  produce locally
heavy rain and hail today and Friday. Outflow wind gusts from 30 to
50 mph will also be possible. Winds will mostly  remain terrain
driven with modest onshore westerly pushes each  afternoon in
exposed areas through Saturday. Stronger onshore wind is expected
with a colder trough on Sunday. This trough will also bring another
chance of showers and thunderstorms to mainly the  Klamath Mountains
on Sunday.
