...Discussion from Monterey...

Cooler than normal temperatures will continue into the beginning of
next week. Winds will remain breezy this afternoon into the early
evening however not as strong as we`ve seen the previous couple of
days. RH recoveries will improve within the marine layer as it
builds higher and moves farther inland. Dry air above the marine
layer and farther inland will see MinRH values dip into the 20s and
30s for some higher elevations, and teens in southern Monterey
County.

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 99 will be common, with minimum
 humidities between 8 and 20 percent today, falling to 5 to
15 percent Sunday into Monday. 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 the next few nights. This will result
in a seasonably elevated risk for grass fires in the windy
locations. Over the coastal areas, the marine layer influence will
continue to moderate conditions over the weekend.

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 and 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 large plume dominated fires, especially in the mountains.
Minimum humidities of 8 to 20 percent are expected in the valleys,
mountains, and deserts during the heat wave, with poor humidity
recoveries in the mountains. There is also a small chance (10%) of
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.
