...Discussion from Monterey...

...Elevated to near critical fire weather conditions continue  this
afternoon and evening in the East Bay and Santa Cruz  mountains
driven by sustained winds as high as 30 mph...

Shallow and compressed marine layer remain along  the coast and
locally inland. Onshore flow will remain today  leading to cool
temperatures, moderate humidity, and breezy to  gusty conditions.
Winds will be strong for the higher terrain and  interior
gaps/passes. Gusts 40-50 mph will be possible for the  windiest
locations, especially the East Bay. Cool onshore flow  remains for
the weekend as well.

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

...EXTENDED HEAT WAVE WITH WIDESPREAD ELEVATED TO BRIEF CRITICAL FIRE
WEATHER CONDITIONS WITH THREAT OF LARGE PLUME DOMINATED FIRES NEXT
TUESDAY THROUGH FRIDAY (JULY 8-11) ALONG WITH SMALL RISK OF
MONSOONAL THUNDERSTORMS...

Minor warming and drying expected each day through Monday. Over the
interior areas, highs between 88 and 98 will be common, with minimum
 humidities between 10 and 20 percent. Pockets of humidities down to
5 to 10 percent are likely in the deserts and higher peaks,
especially over  the weekend. Southwest to northwest winds 15 to
25 mph with gusts to 35  mph will be common over the interior
valleys and mountains, with isolated gusts up to 40 mph in the
Antelope Valley foothills. Sundowner winds of similar strength will
form over southwest Santa Barbara County by tonight.  This will
result in a seasonably elevated risk for grass fires in the windy
locations. Over the coastal areas, the marine layer will  moderate
conditions.

A significant heat wave will impact the area next week Tuesday
through  at least Friday. While there remains a range of outcomes in
terms of  the magnitude of this heat wave, the peak continues to be
centered on  Wednesday Thursday (July 9-10), at which time high
temperatures between  98 and 108 are looking like the most likely
outcome for most lower  mountains, valleys (including coastal
valleys), and deserts. Deep mixing heights  will increase the risk
for plume dominated fires. Minimum humidities  will likely be under
15 percent for most areas away from the coast.  There is also a
small chance monsoonal thunderstorms over the mountains  and
deserts, especially towards the end of next week. Southwest to
northwest winds of 15 to 25 mph with gusts to 35 mph will likely
continue over the typically wind prone areas. All of this likely
adds up to an elevated to locally brief critical fire weather
scenario. While  the chance of reaching classic Red Flag Warning
criteria remains low,  considering recent fire behavior and the high
risk for plume dominated  fires, if the hotter outcomes play out a
Red Flag Warning might be  considered. Heat Advisories look certain,
with chance for Heat Warnings.
