.KEY MESSAGES...

* Expect increasing southwest winds and cooling temperatures this
  weekend and into next week.

&&

.DISCUSSION...through Friday.

A persistent trough will be the main driver of weather through the
weekend and next week. First, temperatures will fall back to near
normal values by Sunday, which means highs in the upper 90s to low
100s across much of the Mojave Desert. HeatRisk decreases from
Moderate(Level 2 of 4) to Minor (Level 1 of 4) for most locations as
a result. Highs should remain within a few degrees of normal
throughout the week. The position of the trough will allow for an
increase in southerly to southwesterly winds across much of the
area. The strongest gusts should generally remain in the 30 to 40
mph range today, which will create rough waters and waves between 2
and 4 feet on Lake Mead and Lake Mohave. Gusty winds combined with
dry conditions also raise elevated to critical fire weather
concerns - see the FIRE WEATHER discussion below for more
details. Winds may weaken a bit on Sunday, but are expected to
strengthen again on Monday and Tuesday as the trough becomes
reestablished. Additional periods of breezy winds are possible
later in the week depending on the strength and position of the
trough, but confidence in this setup is lower at this time.

.AVIATION...For Harry Reid...For the 18Z Forecast Package...Winds
will remain southwesterly through Sunday afternoon. Speeds will
remain elevated into tonight, with occasional gusts of 25 to 33
knots into the early evening. Gusts will decrease after that,
although gusts to around 25 knots will remain possible through
sunrise. A brief lull in the winds is possible Sunday morning, but
southwest gusts will redevelop by Sunday afternoon. VFR conditions
will prevail into Sunday with SCT to BKN clouds with bases AOA 15kft
AGL moving across the region this evening through Sunday morning.
Temperatures are expected to exceed 100 degrees from 19Z to 02Z,
topping out around 102 degrees. Temperatures on Sunday should top
out in the upper 90s.

For the rest of southern Nevada, northwest Arizona and southeast
California...For the 18Z Forecast Package...Southerly to
southwesterly winds will continue to increase through the afternoon,
with occasional gusts of 20 to 30 knots expected to continue into
the evening. One exception will be across the western Mojave Desert,
including KDAG, where winds will favor a more westerly direction and
gusts will be in the 25 to 35 knot range. Another exception is the
northern Owens Valley, including KBIH, where winds will remain light
and favor typical diurnal directional trends until gusty westerly
winds develop by mid-afternoon. VFR conditions will persist through
the TAF period with SCT to BKN clouds with bases AOA 15kft AGL
moving across the area this evening through Sunday morning.

&&

.FIRE WEATHER...A combination of widespread southwesterly winds of
15 to 25 mph gusting between 30 and 40 mph, minimum RH values
between 5 and 15 percent, and dry fuels bring critical fire weather
conditions to much of the area today. Red Flag Warnings cover all of
southern Nevada and northwestern Arizona except for Nevada Zone 460.
This warning continues into Sunday for northwestern Arizona, where
gusty winds will persist as the trough moves east. Another round of
gusty winds and dry conditions is expected on Monday and Tuesday as
the trough strengthens again, and a Fire Weather Watch has been
issued for all of northwestern Arizona and most of southern Nevada
for this time as well.

&&

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