.DISCUSSION...Today through Tuesday.

Expect dry conditions, temperatures within a few degrees of seasonal
normals, and afternoon breeziness through the work week. Shortwave
ridging will persist across the Desert Southwest for another day
before a weak closed low pushes into the central California Coast
and across the Great Basin on Wednesday. Impacts from this system
will be minimal, with only a slight uptick in wind speeds across the
forecast area (10 to 20 mph gusts in the afternoon, with gusts to
25 mph in the higher terrain).

Heading into the weekend, heights will increase west-to-east thanks
to a high pressure system in the eastern Pacific Ocean. This will
allow temperatures to increase to slightly-above normal. In addition
to this ridge, a shortwave will move along the upper-level flow and
will ultimately cut off in the southeastern Pacific Ocean late-week
into the weekend. Associated with this trough axis, an open wave
will push southeastward through our forecast area on Saturday. The
resultant tightened pressure gradients across the region will
increase northerly wind gusts on Friday and Saturday to 15 to 25
mph. Along the Colorado River Valley, these north winds will be
enhanced by local topographic features, which will allow speeds to
range 30 to 40 mph at times, with wave heights on Lake Mohave and
Lake Havasu to 3 feet. Will continue to assess the need for a wind-
related headline as we get closer. Quiet conditions return for the
remainder of the weekend into the start of next week.

.AVIATION...For Harry Reid...For the 12Z Forecast
Package...Light winds will persist through the morning. Winds will
become north around 18Z before veering northeast at 040-050 degrees
(true) after 21Z, but speeds will likely remain under 8KT through
the afternoon at KLAS. KHND will also see winds under 8KT, but
expect northwest winds at KVGT around 10KT this afternoon with
isolated gusts up to 20KT. Winds will shift to a typical overnight
wind direction under 8KT around sunset. Moderate confidence that
winds will become northwest again at KLAS around 09Z then persist
into early Thursday morning when they will become light and variable
again. VFR skies expected through the period.

For the rest of southern Nevada, northwest Arizona and southeast
California...For the 12Z Forecast Package...In general, light winds
favoring the north to northwest are expected this morning into the
afternoon. The Owens Valley in California as well as the Colorado
River Valley will see stronger north winds at 10-15KT, gusting over
20KT at times this afternoon. Winds will diminish after sunset and
light winds return tonight. Mostly clear VFR skies are expected
through the period.
