.KEY MESSAGES...
1. Elevated fire weather conditions for Northwest Kern County this
afternoon due to low RH around 20 percent and stronger wind gusts
near 30 MPH.

2. Temperatures near season averages across the region today before
a gradual warm up into the triple digits later this week.

3. Low RH values 15 to 25 percent will stretch across much of the
San Joaquin Valley and Sierra Nevada with values 5 to 10 percent in
the Mojave Desert. RH will decrease over the region later in the
week with warming temperatures.

.DISCUSSION...
An upper level area of low pressure has made it to the central
California coast where it is expected to remain mostly stationary
through late Tuesday. Meanwhile, an area of high pressure continues
to strengthen over the Four Corners region.
The two synoptic-scale areas are anticipated to cause overall flow
across central California to track out of the southwest, resulting
in near average temperatures, but increased winds in the lee of the
West Side Hills and Tehachapi Mountains and in typical wind-prone
areas. These winds will combine with seasonably low RH values around
20 percent to result in conditions favorable for elevated fire
danger, especially in places such as west of Lost Hills and at Lake
Isabella.

The aforementioned low is expected to lift into northern California
on Wednesday, allowing the ridge of high pressure to slide westward
over central and southern California. The increasing pressure will
cause temperatures to warm across the region, with a moderate to
high probability (40 to 70 percent) to reach over 100 degrees on
Thursday and a high probability (75 to 95 percent) for Friday. The
rising temperatures will cause a decrease in relative humidity, with
much of the San Joaquin Valley and Sierra Nevada having between 10
and 20 percent RH values; Kern Desert values are expected to remain
in single digits through the forecast period. However, the subsiding
air aloft later in the week will cause a decrease in winds in the
valley areas, and mainly diurnal and terrain driven winds in the
foothill, mountain, and desert areas.
