...Critically low relative humidity expected across the interior
and in higher terrain this upcoming week, especially Tuesday and
Wednesday...

An Excessive Heat Warning is in place for most of our interior
locations, with a Heat Advisory for some locations closer to the
shoreline that may still see minimal influence of the Marine
Boundary Layer. Minimum RH values inland for the upcoming week and
beyond will mostly be in the teens, with some single digit values in
areas of higher elevation. Overnight RH recover will be poor to
non-existent as the heat wave persists through the week, and
potentially into next weekend. The hot and dry conditions continue
to move ERCs into the 70-80 percent range. With the long holiday
weekend, and the many outdoor activities expected, people need to be
careful with any campfires, and fireworks should not be used. Any
wildfire that ignites will have the potential for rapid spread.
Lightning is the only natural ignition for wildfires and there are
no thunderstorms in the forecast.

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

...POTENTIAL FOR GUSTY AND HOT SUNDOWNER WINDS TO BRING ELEVATED TO
CRITICAL FIRE WEATHER CONDITIONS FOR SOUTHERN SANTA BARBARA COUNTY
LATE THURSDAY INTO FRIDAY NIGHT...

A broad upper level trough over the West Coast will gradually weaken
through Monday. This will bring a gradual warming and drying trend
to all areas through Monday with the best warming away from the
coast. The marine inversion will remain quite shallow with night and
morning low clouds and fog confined to the coastal plain. For the
interior valleys, mountains, and deserts, humidity values are
expected to lower to between 8 and 20 percent today and Monday. The
hotter temperatures, low humidities, and locally gusty onshore winds
will bring elevated fire weather conditions across the interior
valleys, mountains, and deserts today through Monday.

Beginning on Tuesday, and continuing into next weekend, high
pressure will build into the region from the Eastern Pacific. This
will likely  bring a significant and long duration heat wave away
from the coast from Tuesday through next weekend. High temperatures
between 100 and 110 degrees will be common across the interior
during this period, with temperatures potentially rising to between
110 and 115 degrees across the Antelope Valley and San Luis Obispo
County interior valleys during the peak of the heat Thursday through
Saturday. Overnight lows will also remain quite warm, adding to the
potential for dangerous heat mid to late week. Widespread humidity
values between 7 and 15 percent will likely occur across the
interior during this period, along with poor humidity recoveries,
especially in the mountains, foothills, and Antelope Valley. Typical
gusty onshore winds are expected across interior sections in the
afternoon and evening hours, with gusts of 20 to 35 mph common.
There is also the potential for gusty sundowner/I5 corridor winds
late Thursday into Friday night which could bring hot and dry
conditions into portions of southern Santa Barbara county.

Given the very hot temperatures, low relative humidity, and locally
gusty winds, an extended period of elevated to brief critical fire
weather conditions are likely from Tuesday through Sunday for
valley, foothill, mountain, and desert locations. Elevated to
critical fire weather conditions may expand into southern Santa
Barbara county if the sundowner winds develop late Thursday into
Friday night. The hot and unstable conditions will also increase the
threat of large vertical plume growth for any fires that develop
across the interior. The very hot and dry conditions will also cause
a significant drop in both live and dead fuel moisture levels this
week. These drying fuels combined with the expected fire weather
conditions and increased outdoor activities due to 4th of July will
cause the large fire threat to become high for areas away from the
coast Tuesday through next weekend.
