...Elevated fire weather conditions return for interior valleys
on Thursday and Friday...

A few hours of critical fire weather conditions are expected into
the evening hours across the interior foothills and the Antelope
Valley  due to 5-11 percent humidity and gusty southwest winds to
35-45 mph  at times. For tonight the high pressure ridge will
continue to weaken over the district and a Catalina Eddy forms over
the coastal waters. A weak Sundowner will occur for the west-end of
the south Santa  Barbara coast during the evening hours with locally
gusty northwest  winds. Overall there will be an improvement in
humidity recoveries  and more coastal cloud cover by morning with a
marine layer depth  nearing 1500 feet.

Wednesday will bring a few degrees of cooling with an uptick in
minimum humidities, most noticeable for coastal zones. An upper
trough will swing across the Great Basin in the afternoon resulting
in gusty west to northwest winds of 30-45 mph developing across the
northwest San Gabriel Mountains and the Antelope Valley with these
areas remaining breezy into Thursday morning.

The high pressure ridge will start to rebuild across the eastern
Pacific Ocean and southwest California Thursday and Friday. This
will lead to a shrinking marine layer along the coast and warmer
temperatures and lowering humidities across the fire district.
Minimum humidities from 8-15 percent and gusty afternoon winds will
return to the interior valleys for critical fire weather potential.
A weak low pressure trough will slide across the district on
Saturday with slight cooling and increased humidity expected for the
weekend.


...Discussion from Monterey...

Onshore flow with a weak and deep marine layer will continue into
mid to late week. An upper level ridge will build over the district
beginning Thursday. Humidity recoveries will generally be good to
very good through the period.

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