.KEY MESSAGES...

* Breezy south-southwesterly wind gusts will continue through the
  week with dry conditions and near-normal temperatures.

&&

.DISCUSSION...Persistent troughing across the Western US will keep
the region in a generally dry and breezy pattern through much of
the upcoming week. In the near term, a trough will eject into the
Northern Plains today before additional troughing drops south
along the Pacific Northwest Coast by midweek. This will keep the
Mojave Desert and southern Great Basin region in a southwesterly
flow aloft, favoring breezy conditions in the afternoons and any
lingering monsoonal moisture focused more across central and
eastern Arizona. A few isolated thunderstorms may develop across
eastern Mohave County through midweek, but coverage is expected
to be quite limited.

Otherwise, thanks to the pattern at hand, temperatures will remain
near seasonal normals through the period. The flow pattern will
trend more zonal by the weekend allowing for the gusty winds to
ease while temperatures remain near normal.

.AVIATION...For Harry Reid...For the 06Z Forecast Package...Light
southwest winds tonight give way to breezy south-southeast winds
Tuesday morning and afternoon. Some uncertainty exists in the exact
wind direction and magnitude during the morning hours (15z-19z).
Think on average, winds during this time will be from ~160, but
wouldn`t be surprised to see periods as far east as 120. By mid-
afternoon, expecting a gradual turn to a more true south direction.
Gusts 15-25 knots likely (90%), with 30+ knots possible (25%). Winds
should subside after sunset and remain from the south-southwest
overnight. Mostly clear skies with just a few mid-level afternoon
clouds. Temps peak just shy of 100F on Tuesday.

For the rest of southern Nevada, northwest Arizona and southeast
California...For the 06Z Forecast Package...Breezy south winds
linger tonight in areas southeast of I-15, but elsewhere light winds
are expected. Southerly to southeasterly winds pick up across most
of the region Tuesday morning and persist through sunset. Peak gusts
of 15-30 knots are likely (90%). Isolated convection possible (10-
20%) across northwestern Arizona and eastern Lincoln County Tuesday
afternoon/evening. Here, few to scattered clouds around 10kft are
expected, but mostly clear skies farther west.

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