.SYNOPSIS...Generally dry and unseasonably warm conditions will
continue through most of next week across the region as high
pressure continues to dominate the Western US. A modest cool down
is possible next weekend along with a return of breezier
conditions, though above normal temperatures will persist.

&&

.UPDATE...Mostly virga, but could be some light showers mixed in
this evening along the eastern Sierra slopes of Inyo County and
higher terrain of south central Nevada. That activity should vanish
in another hour or two with the loss of daytime heating. Looks to be
a similar setup tomorrow with a weak disturbance moving into
northern California potentially producing some additional dynamics
along the Sierra and higher terrain of central Nevada. Again, expect
little rain to reach the ground with main threat being gusty winds.

Numerous records set or tied again today across the area with a very
slow lowering of temperatures through the week. There is not need
for an update this evening.

.DISCUSSION...through next weekend.

Mid-level moisture moving in off the Pacific has resulted in some
weak virga showers across the Sierra and higher peaks of the
Southern Great Basin. Not expecting any of this development to
amount to much, but could be some locally gusty winds beneath
their bases thanks to the dry low level airmass in place.
Otherwise, not much weather to speak of beyond the continued
heat. KLAS is running about 3 degrees cooler today than yesterday,
so reaching 100 may be a struggle today, but the daily record is
98 which is still well within reach. The current excessive heat
warning for the Colorado River Valley, Morongo Basin, and Death
Valley continues through Monday evening, with little day-to-day
change in temperatures expected.

Starting Tuesday, a very slow decline in heights is expected as a
very weak upper level trough gets nudged into the ridge. This
will help offset temperatures slightly, though it will remain well
above normal through Friday. By the weekend, a transient trough
entering the Western US may knock temperatures down further and
stir up the regional winds, but guidance remains uncertain on
it`s strength and timing. As such, only a slight decrease in temps
is advertised for the weekend.

.AVIATION...For Harry Reid...No significant aviation impacts
expected today. Winds are forecast to follow typical diurnal
patterns, favoring an easterly direction during the day and a west-
southwest one at night. Chance of speeds reaching 10 knots is ~10%.
A few mid-level clouds this afternoon but skies remain mostly clear
throughout the day.

For the rest of southern Nevada, northwest Arizona and southeast
California...No significant aviation impacts anticipated at KDAG and
the Las Vegas Valley sites today as winds remain light and diurnal.
In the Colorado River Valley, breezy north winds linger through the
afternoon. Gusts of 15-25 knots possible during the morning and
early afternoon, gradually waning in the late afternoon and evening.
The most forecast uncertainty surrounding KBIH, as shallow
convection develops off the Sierra. Don`t have much confidence in
any precipitation reaching the ground in the Owens Valley (hence no
mention of precipitation in the TAF), but erratic breezes may
emanate from this activity and reach the airport. Barring any
influence from virga, winds should remain below 10 knots and follow
typical diurnal trends.

&&

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