...ELEVATED FIRE WEATHER THREAT ACROSS THE EAST BAY HILLS  SATURDAY
AFTERNOON DUE TO LOW RH AND MODERATE WESTERLY WINDS...

High temperatures increase this weekend to a few degrees above
average, which linger into next week. High pressure aloft will
compress the marine layer gradually and provide further drying at
locations above 1,000 feet. Afternoon humidity drops into the teens
at these locations; much better moisture retention at lower
elevations. Winds remain onshore, but will become breezy in the
afternoons during peak heating.

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

...WARMING AND DRYING TREND THROUGH HOLIDAY WEEKEND WITH ELEVATED FIRE
WEATHER CONDITIONS ACROSS INTERIOR INCLUDING RISK OF LARGE PLUME
DOMINATED FIRES...

...POTENTIAL INCREASE IN MONSOONAL MOISTURE AND INSTABILITY WILL
BRING THREAT OF THUNDERSTORMS AND ENHANCED RISK OF LARGE PLUME
DOMINATED FIRES...

Lingering mid level moisture and instability will bring a slight
chance of afternoon thunderstorms across the eastern San Gabriels,
with the main risks  being isolated dry lightning strikes and gusty
downdraft winds.  Any fire starts that could develop today will make
initial  attack difficult due to erratic and gusty winds.

Temperatures will warm today through Tuesday as high pressure aloft
reestablishes and builds back into the Four Corners Region. The peak
of the heat will be Monday through Wednesday, when highs of 95 to
105 will be  common across the interior. The hotter temperatures
combined with  increased instability will bring deeper mixing
heights which are expected to peak on Tuesday and Wednesday at
12,000 to 18,000 feet across the interior. As a result, there is an
elevated risk for large plume dominated fires across the interior.
Humidities between 10 and 25 percent will be common over the warmest
valleys and mountains through Tuesday, then increasing humidities
due to an influx of monsoonal moistures. This monsoonal threat will
also bring a chance of thunderstorms Tuesday through Friday. The
best chances (15-25%) will be in the mountains and Antelope Valley,
but there is also a 10-15% chance of thunderstorms for
coastal/valley areas.
