...Discussion from Monterey...

 Near normal temperatures continue into the mid week, with minRH
falling to 20 to 40 percent for for interior valleys,  the Central
Coast mountains, and interior hills and mountains of  the East and
North Bay.These areas will struggle with overnight humidity
recoveries tonight, but recoveries look to improve in the second
half of the week. Expect breezy onshore winds up to 30 mph will be
possible for ridges, gaps, and channels over the next few
afternoons, with winds reducing into each night. Temperatures  look
to warm slightly for the weekend, with some slight drying  over the
weekend for itself. There will be a push for marine  stratus for the
coastal areas through the next few days, with a  compressed but
still defined marine layer expected over the  weekend.


Note : All winds are 20-foot Winds Unless otherwise specified.
Thunderstorms imply strong, gusty and erratic winds.

...THUNDERSTORMS POSSIBLE THROUGH TONIGHT, WITH RISKS FOR LOCALIZED DRY
LIGHTNING, STRONG WINDS, AND FLASH FLOODING...

An upper level low pressure system is sweeping just south of the
region and yielding scattered thunderstorms through tonight.
Convective  activity will be most active during this afternoon and
evening through  around 9 PM. While any location could see a storm,
the areas most  favorable include the San Gabriel Mountains and
valleys, the Antelope  Valley, the interior mountains of Ventura
County. Storms overall are  moving southwest towards the valleys and
coasts. With dry air near the  surface, any thunderstorm that forms
may produce downburst winds up to around 50 mph and the potential
for dry lightning, especially for the foothills and lower mountains.
Brief heavy downpours and small hail are also possible with storms,
with the chance for rain rates up to  around 0.75 inches per hour.
This includes the Bridge Fire and Eaton  Burn Scars, where there is
a small but present risk for debris flows.

Otherwise, there will be lingering chances of mountains showers
Wednesday afternoon, followed by fairly seasonal and mild fire
weather  conditions, with a deep coastal marine layer and typically
gusty onshore winds over the interior. Later this week, low
humidities will affect the higher elevations and Antelope Valleys
and there will continue to be a  persistent risk for grass fires.
