.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 06Z Forecast Package...Clear
skies and light winds continue through the TAF period. Expect
variable wind directions through the night but winds look to turn
more northerly into the mid morning. These winds will remain light
but turn north-northeast into the afternoon. Winds become lighter
and variable into Wednesday night.

For the rest of southern Nevada, northwest Arizona and southeast
California...For the 06Z Forecast Package...Winds stay light across
much of the region through the TAF period. The exceptions will be at
KDAG which sees gusty winds build from the west overnight but ease
into the morning, and the Colorado River Valley sites (KIFP and
KEED) which will see breezy winds from the north tomorrow afternoon
and into the night.

.SPOTTER INFORMATION STATEMENT...Spotters are encouraged to report
any significant weather or impacts according to standard operating
procedures.
