...RED FLAG WARNING REMAINS IN EFFECT UNTIL 5 AM PDT FRIDAY FOR
CRITICALLY DRY FUELS AND LOW HUMIDITY FOR THE MARIN AND SONOMA
COASTAL RANGES...

...RED FLAG WARNING NOW IN EFFECT UNTIL 9 PM PDT SATURDAY FOR
CRITICALLY DRY FUELS AND LOW HUMIDITY FOR NORTH BAY INTERIOR
MOUNTAINS, EAST BAY HILLS, AND SANTA CRUZ MOUNTAINS...

...RED FLAG WARNING IN EFFECT FROM 9 AM FRIDAY TO 9 PM PDT SATURDAY
FOR WINDS, CRITICALLY DRY FUELS, AND LOW HUMIDITY FOR  SANTA LUCIA
MOUNTAINS, MOUNTAINS OF SAN BENTIO COUNTY AND INTERIOR MONTEREY
COUNTY, AND THE SOUTHERN SALINAS VALLEY...

Northerly winds are gusting in the 20-30 mph range  mph overnight,
with Mt. St Helena gusting as high as 64 mph and Mount Diablo at
54 mph early this morning. While winds will begin to diminish over
the next few days, these RFW extend through 9 PM Saturday evening
due to the critically dry conditions. In fact,  10 and 100 hour
fuels are near historic levels in the Santa Cruz,  Diablo and North
Bay Mountains in regard to the energy release  component going into
the weekend. In addition to the hot, dry  weather, the 4th of July
Holiday may lead to new starts from stray fireworks. Further south,
things start to dry out more this  weekend.

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

...RED FLAG WARNING IN EFFECT FOR THE INTERSTATE 5 CORRIDOR, VENTURA
MOUNTAINS, AND SOUTHERN AND CENTRAL SANTA BARBARA COUNTIES...

...FIRE WEATHER WATCH IN EFFECT ON FRIDAY FOR INTERIOR SAN LUIS
OBISPO COUNTY AND CUYAMA VALLEY...

...WIDESPREAD ELEVATED FIRE WEATHER CONDITIONS ELSEWHERE ACROSS
VALLEYS AND MOUNTAINS THROUGH MUCH OF NEXT WEEK, MOST SIGNIFICANT
FRIDAY AND  SATURDAY...

Temperatures will continue to climb each day through the week as
humidities fall and dry air expands. Friday and Saturday are
especially extreme as onshore flow weakens, high pressure aloft
peaks, and the marine layer possibly erodes away. Over the mountains
and interior  valleys, high temperatures will climb to 108 to 118 by
Friday with all  time records threatened. Minimum humidities will
fall to 6 to 12  percent by Friday. Over the coastal valleys, high
temperatures will  climb to 100 to 110 by Friday. Minimum humidities
will fall to 12 to 20  percent. Coastal areas will also warm and dry
significantly, but exactly how the marine layer behaves will drive
the magnitude. There is more  clarity on southern Santa Barbara
County however as moderate Sundowner  winds will clear the marine
layer and allow temperatures to rise into  the 90 to 100 degree
range on Friday with minimum humidities falling to 12 to
25 percent...especially in the foothills. Overnight lows between
75 and 85 will be common in the mountains and foothills with
moderately  poor humidity recoveries of 25 to 45 percent. Meanwhile,
the winds will turn to northwest to northeast Thursday and Friday,
with gusts of 25 to 40 mph possible over Santa Barbara County, many
mountains, and the  Antelope Valley. While classic Red Flag
thresholds will likely not be met, considering the extreme nature of
this event and the holiday fire  ignition sources available,
conditions are favorable for critical fire  weather behavior.

Less hot conditions are likely for the coastal and adjacent valley
areas by Sunday or Monday, but the extremely hot conditions will
change  little over the at least the mountains and interior through
most if not all of next week. This is one of the longest and most
extreme heat  waves on record for interior areas. Elevated fire
weather conditions  will continue for the foreseeable future, with
rapidly drying fuels and the potential for plume dominated
wildfires. There is a high risk for  heat related illness.
