.KEY MESSAGES...
1. Drier air will cause minimum relative humidity to fall
between 10 and 20 percent for much of the region through the
forecast period. There is Moderate Fire Risk as a result.

2. Temperatures are expected near normal for much of the area
with Minor Heat Risk in the San Joaquin Valley and Moderate
Heat Risk in the Kern County Desert.

3. Stronger wind gusts are possible in the Mojave Desert Slopes
Monday afternoon into Tuesday morning; there is a 40 to 80
percent chance for gusts greater than 45 mph. A Wind Advisory is
in effect from 2 PM Monday through 2 AM Tuesday.

.DISCUSSION...
A slight building of a high pressure ridge to our southeast will
result in warmer temepratures this afternoon compared to the
past few days. These warmer temperatures will give way to near
average conditions tomorrow and Tuesday as a shortwave trough
passes through central California. The orientation of this piece
of energy is expected to cause stronger winds to develop in the
lee side of the local ranges, particularly in the West Side
Hills and the Mojave Slopes/Walker Pass area.

A sudden warm up will follow midweek as high pressure builds in
again behind the aforementioned trough. There is a 30 to 60
percent chance for much of the San Joaquin Valley to exceed 100
degrees Wednesday, with lower chances on Thursday except for
Bakersfield (80 percent chance), Hanford (55 percent chance),
and Visalia (65 percent chance).

A much stronger trough dropping southward from the Pacific
Northwest will result in a cooling trend into next weekend with
potential for below-average temperatures in the upper 80s next
Saturday.
