.DISCUSSION...through next Friday.

An unseasonably strong trough can be seen pushing into the Pacific
Northwest on infrared and water vapor satellite imagery tonight.
This low pressure system will continue to push inland and dig south
over the next few days, resulting in gusty southwesterly winds
picking up across the region. These winds, combined with low
humidity and critical fuels will result in increased fire danger
today and tomorrow for portions of southern Nevada and northwest
Arizona. As such, multiple Red Flag Warnings are currently in
effect. More details regarding the Red Flag Warnings can be found in
the FIRE WEATHER discussion below.

In addition to Red Flag Warnings, multiple Wind Advisories have been
issued for wind gusts in excess of 40 mph. A Wind Advisory will go
into effect for the western Mojave Desert this afternoon and will
run through Saturday night. Another Wind Advisory will go into
effect for Mohave County on Saturday morning, running through late
Saturday night. Additionally, 20 to 25 mph sustained southwesterly
winds with gusts up to 40 mph will result in 1 to 3 foot waves on
Lake Mead, Lake Mohave, and Lake Havasu on Saturday. As such, a Lake
Wind Advisory has been issued for the Colorado River Valley for
Saturday.

As the aforementioned trough digs into the area, we will see
temperatures decrease with cooler than normal temperatures on tap
for the region over the weekend. These cooler than normal
temperatures will persist into early next week as the trough remains
positioned over the Desert Southwest.

.FIRE WEATHER...A Red Flag Warning remains in effect for Nevada
Fire Weather Zones 461, 462, 463, and 464 through 11:00 pm PDT
tonight. An additional Red Flag Warning remains in effect through
11:00 pm PDT/MST Saturday night for Nevada Fire Weather Zones 465
and 466, as well as Arizona Fire Weather Zones 101 and 102. 20 to 25
mph sustained southwesterly winds are expected across southern
Nevada and northwest Arizona today. These winds will be accompanied
by wind gusts up to 40 mph. Afternoon relative humidities will
bottom out in the single digits with overnight recoveries in the 15
to 25% range. Low humidity will persist into Saturday, with strong
winds persisting across far southern Nevada and Mohave County. As a
result of the low humidity and strong winds, there is an increased
risk of wildfire starts and spreading. Outdoor burning and
recreation involving sparks or flames is not recommended. Winds
across the region will decrease on Sunday, which will mitigate
wildfire risk.

.AVIATION...For Harry Reid...For the 18Z Forecast Package...South to
southwest winds are expected today through Saturday, with gusts of
27 to 32 knots expected this afternoon and again Saturday afternoon.
Winds will decrease slightly overnight, although occasional gusts to
25 knots. No weather or significant cloud cover is forecast.
However, smoke from distant fires burning in northern Mexico may
occasionally reduce slantwise visibility today, especially along the
eastern approaches. Temperatures will exceed 100F between 20Z and
02Z, with a maximum of 103F expected around 00Z.

For the rest of southern Nevada, northwest Arizona and southeast
California...For the 18Z Forecast Package...Conditions at the Las
Vegas area terminals will be similar to those described above for
Harry Reid.  Winds at KBIH will be variable this morning, but gusty
southwest to west winds will develop by mid-afternoon and persist
for several hours before turning back to the north. Across the
western Mojave Desert, strong west winds will continue with gusts as
high as 40 knots possible at KDAG.  Winds will be a bit lighter in
the Colorado River Valley, although gusts of 25-30 knots will be
possible at both KEED and KIFP.  No weather or significant cloud
cover is forecast through Saturday. However, smoke from distant
fires burning in northern Mexico may occasionally reduce slantwise
visibility today, especially in and near the Colorado River Valley.
