  weekend and into next week.

.DISCUSSION...through Thursday.

Our stretch of calm and unseasonably warm weather culminates today.
Temperatures are forecast to be nearly identical to yesterday, with
100-110 generally across the Mojave Desert and 90s in the southern
Great Basin and Arizona Plateau. This results in widespread moderate
HeatRisk with a pocket of major HeatRisk in the Las Vegas Valley
where overnight lows remain elevated thanks to urban influences.

Some temperature relief arrives this weekend and continues into next
week as troughing settles over the western US. Afternoon highs are
forecast to be near normal values for early/mid June. With the
better forcing staying north and limited moisture, precipitation
chances are likely to be confined to the Great Basin. PoPs across
our southern Great Basin zones only get up to ~20% early next week.
The main story with this trough is going to be the increase in
southwest wind and fire danger. Chances for 40+ mph gusts on
Saturday are moderate (40-50%), but not quite high enough to justify
issuing a Wind Advisory. Won`t be surprised to see a few gusts of 40-
45 mph in the Kingman and Barstow areas, but these should be fairly
sporadic and localized. However, boating impacts appear more likely
(70%), thus have opted to issue a Lake Wind Advisory for Lake Mead
and Lake Mohave on Saturday. Winds subside slightly on Sunday but
tick back up next week as the trough gets reinforced. There remains
some uncertainty in exactly how strong/impactful the winds may be
during this time, but will certainly be enough to keep fire danger
elevated.

.AVIATION...For Harry Reid...For the 00Z Forecast
Package...Southwest winds gusting to around 20KT will continue into
the evening before diminishing after sunset. Gusts will end after
03Z but south winds will continue at 10KT through much of the night.
After a brief period of light and variable winds early Saturday
morning, gusty southwest winds will return Saturday late morning and
afternoon. Gusts 20-25KT are expected in the late morning before
increasing to around 30KT in the afternoon. Winds will continue to
gust into Saturday evening, but should drop back closer to 20-25KT
after sunset. VFR conditions with clear skies become SCT-BKN at or
above 20kft Saturday will persist through the period. Temperatures
will remain over 100 degrees through 03Z tonight, then will climb
over 100 degrees again Saturday 20Z through 02Z.

For the rest of southern Nevada, northwest Arizona and southeast
California...For the 00Z Forecast Package...Breezy south to
southwest winds will continue through the evening with gusts 15-25KT
in most locations. Winds will diminish after sunset with light winds
following typical directional patterns overnight. The exception is
around KDAG where west winds around 15KT will continue through much
of the night. On Saturday, stronger southwest winds are expected
across the area as 25-35KT gusts develop in the late morning and
afternoon. VFR conditions will persist through the period.

.FIRE WEATHER...Widespread southwest winds of 15-25 mph with gusts
around 35 mph on Saturday. Combined with minimum RH values of 5-15%
and fuels approaching critical, Red Flag Warnings cover all of
southern NV and northwestern AZ except for Nevada Zone 460. The
warning continues on Sunday for northwest AZ and the NV side of the
Colorado River Valley. Near to critical fire weather conditions look
likely to persist into early next week as the trough reloads. A Fire
Weather Watch has been issued for all of our AZ zones and most of
our NV zones on Monday and Tuesday.

&&

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