.KEY MESSAGES...
1. Minor Heat Risk will be present for most of the lower
elevations today with Moderate Heat Risk in the Kern County
Desert.

2. Drier air will cause minimum relative humidity to fall
between 10 and 20 percent for much of the region through the
forecast period.

3. A minor cooling trend continues into the weekend with
seasonably warm temperatures by Saturday.

4. Stronger wind gusts are possible in the Mojave Desert Slopes
later this evening with a 40 to 60 percent chance to exceed 35
mph.

.DISCUSSION...
Seasonable temperatures will continue across the lower
elevations of central California today as zonal flow causes
winds to propagate from the west. Much of the incoming air will
be drier than in previous weeks and widespread minimum relative
humidity values 10 to 20 percent are expected as a result. As we
move further into the weekend, the zonal pattern will erode as
an upper level trough makes its way through the Pacific
Northwest region. Cyclonic flow around the trough will cause
flow over central California to shift from the southwest,
resulting in temperatures a few degrees cooler than during the
work week and near average for this time of year. Some elevated
winds are possible across the area, especially on the east side
of the Sierra, in the Mojave Desert, and in wind-channeling
terrain.

The aforementioned trough is favorable to hold stationary
through the early portion of next week before progressing
further eastward Tuesday afternoon. High pressure will gradually
build in, causing warmer temperatures to return; there is a 20
to 60 percent chance for 100 degree highs for Wednesday and
Thursday. However, these will be short-lived as ensemble
guidance shows increasing potential for another trough to
approach the Pacific coast late next week.

.AVIATION...
06Z Update:

VFR conditions will prevail for the next 24 hours across the Central
California Interior.

&&

.FIRE WEATHER...
Minor risk for fire development through the weekend and into
next week due to low minimum relative humidity values between 10
and 20 percent. The greatest threat for new fires will be in
areas with cured fine fuels, though the upcoming low RH`s will
cause a relatively sharp decrease in 100-hr fuel moisture. Wind
gusts across the valley areas will reach 15 to 20 knots each
day.
