...Discussion from Monterey...

A cooling trend will suppress fire weather  conditions through the
middle of next week, however moderate  onshore winds will continue
each afternoon. There is a chance for  the first wetting rain of the
season in the North Bay early next  week as a cold front pushes
through. Even without any rain, the  cooler weather and higher
humidity will bring fuel energy back  below normal for this time of
year.

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

...ELEVATED FIRE WEATHER CONDITIONS ACROSS THE INTERIOR THROUGH THE
WEEKEND DUE TO WARM AND DRY CONDITIONS COMBINED WITH LOCALLY GUSTY
ONSHORE WINDS...

The monsoonal moisture and instability continues to diminish across
our mountains and deserts. While there could still be some afternoon
cloud buildups across the mountains, there is not expected to be any
thunderstorm activity today.

As the upper level ridge of high pressure continued to weaken and
onshore flow near the surface gradually increases, there will
continue to be a slight downward trend in temperatures the next few
days, but still very warm across the interior with temperatures well
into the 90s through the weekend. In addition, marine layer low
clouds and fog will continue to reestablish each night and morning
across coastal and coastal valley areas through the weekend. The
very warm temperatures across the interior combined with residual
instability will result in moderately deep mixing heights between
9,000 and 12,000 feet each afternoon through Saturday. As a result,
there is still an elevated risk for large plume dominated fires
across the interior.

Typical diurnal winds are anticipated for the next several days,
except for Sundowner winds for southwestern Santa Barbara County
during the evenings (northwest 15 to 25 mph with gust to 35 mph).
With a drying air mass, the humidity levels will trend down the next
few days, with minimums between 8 and 20 percent becoming common
today through Sunday. The warm and dry conditions combined with
locally gusty onshore winds each day will bring elevated fire
weather conditions across the interior through the weekend.
