Area Forecast Discussion
National Weather Service Las Vegas NV
134 PM PDT TUE AUG 30 2016

.SYNOPSIS...Breezy conditions and a slight chances of thunderstorms
will return to northwest Arizona, and perhaps portions of southeast
California and Nevada Wednesday through Friday. Dry conditions with
temperatures cooling a little below normal can be expected over the
weekend and early next week.

.SHORT TERM...Today through Friday.

Other than some cumulus development over the higher terrain and
breezy conditions across the northwestern areas, there`s little
sensible weather today. Things may become a bit more active
Wednesday through Friday this week as an eastern Pacific trough
draws moisture into the region. Moisture advection will begin
Wednesday and will be mainly directed across Mohave County. However,
at least the GFS is indicating some weak advection further west, and
thus I have kept in a mention of showers/storms in the Yucca Valley
area as well as the higher terrain of the Mojave Preserve and Clark
County mountains. Breezy conditions will spread east...encompassing
most of southern Nevada and southeast California.

As the aforementioned trough pushes closer to the coast Wednesday
Night, a shortwave is expected to round its base and interact with
the leading edge of the moisture plume moving north. This could
result in a few showers (probably light showers/virga) from the
Spring Mountains north through Lincoln County and points north.

Moisture advection will continue across at least Mohave and eastern
Lincoln counties on Thursday and when combined with the added
dynamics from the trough should result in an uptick in convection.
Winds will also trend upward Thursday, but at least for now look to
remain just below wind advisory and Red Flag criteria in the peak
areas (Inyo, Esmeralda, and Nye Counties).

Things will begin to wane Friday as the tough axis draws near and
pushes drier air into the region. Drying will occur from west to
east as gusty winds overspread the region. Again, winds appear
borderline for Red Flag and advisory conditions and will need to be
monitored closely.

.LONG TERM...Saturday through Tuesday.

The trough axis will cross the region Saturday and dry and
relatively cool conditions are expected through the weekend and
likely into early next week. Winds should taper off through the
weekend. All in all a pleasant holiday weekend is expected.

.AVIATION...For McCarran...Continued light winds through tonight,
favoring the typical southwest direction. Winds tomorrow will start
off light and variable once again, favoring an easterly direction
before gustier southerly winds begin to push in for the afternoon.

For the rest of southern Nevada...northwest Arizona...and southeast
California...Gusty winds have developed in the Owens Valley this
afternoon, but lighter winds remain for the rest of the region.
Gusty south winds will become more widespread tomorrow with the
Colorado River valley starting as early as late morning and the rest
of southern Nevada and southeastern California gusting by the late

.SPOTTER INFORMATION STATEMENT...Convection is expected to
return to the forecast for at least Mohave County Wednesday.
Spotters are encouraged to report significant weather according to
standard operating procedures.
