.SYNOPSIS...Additional rounds of showers and thunderstorms are
possible through midweek as sufficient moisture and instability
remain in the area. Precipitation totals should be light and most
activity will take place over high terrain. The area slowly dries
out and temperatures begin to climb as a ridge builds later this
week.

&&

.SHORT TERM...Today through Wednesday.

The center of the low pressure system will migrate from Arizona into
the Rocky Mountains today, while another low moves southeast along
the California coast. The forecast area sits between these two
features. Very little moisture was scoured out from the eastern
system and PWATS between 200 and 300 percent of normal remain over
the area. Showers are currently over parts of Mohave and Clark
counties early this morning, producing light rainfall and an
occasional lightning strike. Lingering moisture combined with
instability from clearing skies and surface heating should allow for
another round of thunderstorms this afternoon and evening. CAMs show
most of the activity starting in the southern Great Basin and
eastern Sierra this afternoon where clearing is the best, moving
southeast into Mohave and Clark counties in the evening. Most storms
should take place over high terrain, but a few of the stronger cells
may make it into the valleys. Dry low levels suggest that most of
the precipitation will evaporate before it hits the ground with only
light amounts at the surface. Some storms may produce gusty outflows
in excess of 40 mph.

More isolated to scattered showers and thunderstorms can be expected
on Tuesday and Wednesday as the Pacific low pressure system to moves
inland near the international border. Anomalously high moisture
remains as seen in continued PWATs between 200 and 300 percent of
normal. Most activity should take place over high terrain where lift
is the greatest. Forecast soundings suggest these storms will also
be high based, capable of producing gusty outflows and only light
precipitation at the surface. The HREF indicates 1000 to 1500 J/kg
of DCAPE tomorrow afternoon.

.LONG TERM...Thursday through Monday.

Weak northwest flow will continue across the region late in the
week.  A series of weak short waves will move through the flow and
interact with lingering moisture, resulting in slight PoPs through
early Friday.  The best chances will be over the southern Great
Basin and Arizona Strip.  The remaining moisture should move east of
the area by Friday afternoon, bringing an end to the precipitation
chances. Despite the shortwaves, a high-pressure ridge building over
the eastern Pacific and northern Mexico will result in increased 500
mb heights across the Desert Southwest. As such, temperatures will
climb back to 4 to 8 degrees above seasonal norms heading into the
weekend, and temperatures approaching 10 degrees above normal
heading into next week. This will result in desert valleys
experiencing high temperatures in the 100s once again, and
widespread "Moderate" Heat Risk from Sunday onward.

.AVIATION...For Harry Reid...For the 12Z Forecast Package...Early
this morning, there will be a chance of light rain at the terminal
and ceilings between 8K and 12K feet. Clouds should scatter out
later in the morning. Winds will be influenced by the rain showers,
with the most likely outcome being an east or southeast direction
and speeds of six to 12 knots during the day, although confidence in
this is moderate at best. Winds should shift to south southwest
around sunset. Earlier, models had hinted at thunderstorms possibly
getting close to the terminal after sunset. More recent runs have
backed away from that idea, so have removed it from the TAF, but the
probability is not zero.

For the rest of southern Nevada, northwest Arizona and southeast
California...For the 12Z Forecast Package...Rain chances this
morning will affect Mohave, Clark, Lincoln, and extreme eastern San
Bernardino counties, decreasing as the morning goes on. Afternoon
thunderstorm chances are expected in Inyo, Lincoln, Mohave, and
possibly Clark counties, with the primary threats being erratic
gusty winds and low ceilings with terrain obscuration. Thunderstorm
chances should end overnight, with smaller chances returning
Tuesday. Away from storms, winds should be primarily from the south
to southwest with gusts peaking around 15 to 25 knots.

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