.SYNOPSIS...Pleasant conditions will continue through this evening
with mainly clear skies and slightly above normal temperatures.
Gusty southwesterly winds will increase across the region tomorrow
as an area of low pressure approaches the west coast. This system
will then move across the Desert Southwest this weekend, bringing
below normal temperatures, gusty winds, and the chance of a few
isolated showers. Temperatures will return to above normal levels
next week.

&&

.UPDATE...Deep trough oriented north to south off the West Coast has
overspread considerable high clouds across the region this
afternoon. This cloud cover will hang around overnight before
lifting north during the morning tomorrow. As the trough approaches
tomorrow, increased south-southwesterly surface winds are expected,
especially across Inyo County and the Western Mojave Desert.
Overall, these trends are well reflected in the current forecast and
no update is necessary.

.DISCUSSION.
A shortwave moving across the Great Basin this afternoon is
spreading high clouds over the northern half of the CWA. This
system has also resulted in breezy conditions developing across
southern Nevada, northwest Arizona, and the Colorado River Valley.
Peak wind gusts of 20 to 30 mph will continue into the evening,
but should decrease after sunset. On Friday, a large and fairly
deep trough will approach the West Coast, spreading high clouds
and gusty southwest winds across the region. HREF probabilities
for wind gusts over 40 mph across the western Mojave Desert and
Death Valley area have increased to greater than 70 percent for
tomorrow. As a result, a Wind Advisory has been issued for these
areas. While winds will decrease tomorrow night, they are expected
to increase again on Saturday, so I elected to keep the advisory
going through Saturday evening. The Morongo Basin is not included
at this time, but winds to 35 mph are possible in and near Morongo
Valley tomorrow and again on Saturday. If future guidance runs
show an increase in this area, the advisory may need to be
extended farther south.

As the trough pushes inland over the weekend, sharply cooler
temperatures will follow, with high temperatures falling 5 to 10
degrees below normal. Precipitation chances will remain favored
across the Sierra and southern Great Basin, but with 500mb temps
falling to -25C or colder north of I-40, we can`t completely rule
out some stray terrain-driven showers developing even further
south. Guidance has come into better agreement on a slower
eastward ejection of the trough from the area, keeping
temperatures slightly below normal into Monday. Thereafter, high-
pressure ridging will gradually build across the region with
temperatures returning to above normal levels by midweek and
beyond.
