.DISCUSSION...Today through Friday.

Critical fire weather conditions will continue through this
evening for portions of southern Nevada and northwest Arizona as
southerly-to-southwesterly winds continue to ramp up due to an
upper-level trough digging into the area. These winds, combined
with critical fuels and single-digit relative humidities will
result in increased fire danger. As such, a Red Flag Warning
remains in effect for Lincoln County, Mohave County, and portions
of Clark County through later tonight. More details regarding this
Red Flag Warning can be found in the FIRE WEATHER discussion
below.

As the aforementioned trough digs into the area, we will see
southwesterly winds peak across the Mojave Desert this afternoon.
Gusty northwesterly winds will begin to push into Inyo County and
the southern Great Basin around mid-to-late afternoon, working their
way through southern Nevada, southeast California, and northwest
Arizona during the evening as the trough axis swings through.
Given that 40 to 50 mph wind gusts are expected across much of the
region today, Wind Advisories have been issued for Esmeralda
County, Mohave County, and portions of Clark, Nye, and San
Bernardino Counties. Instances of blowing dust resulting in
reduced visibility, unsecured items being blown away, and
difficult driving conditions for high profile vehicles are
expected as a result of these winds. Additionally, a Lake Wind
Advisory is in effect for the Lake Mead National Recreation Area
and Colorado River Valley as gusty winds will result in 2 to 4
foot waves on Lakes Mead, Mohave, and Havasu today.

The cooling trend of the past few days will continue through the
weekend, with below normal temperatures returning to the region
today. Sunday will be the coolest day of the forecast period with
high temperatures around 10 degrees cooler than normal. Temperatures
will remain cooler than normal into early next week as troughiness
lingers across the southwest.

.FIRE WEATHER...A Red Flag Warning remains in effect through
11:00 pm PDT/MST this evening for Nevada Fire Weather Zones 461,
465, and 466 and Arizona Fire Weather Zones 101 and 102. Critical
fire weather conditions are expected across portions of southern
Nevada and northwestern Arizona due to strong winds and low
humidity. 20 to 30 mph sustained southerly-to-southwesterly winds
are expected across the Red Flag Warning with gusts up to 40 mph
across southern Nevada and gusts up to 50 mph across northwest
Arizona. Relative humidities will bottom out in the single digits in
the afternoons. The low humidity combined with the strong winds will
result in an increased risk of wildfire starts and rapidly
growing/spreading fires. Outdoor burning and recreation involving
sparks or flames is not recommended. Dry conditions will persist
into early next week, but winds will decrease beginning on Sunday.
These lighter winds will help to mitigate the wildfire risk.

.AVIATION...For Harry Reid...For the 18Z Forecast Package...South-
southwest winds will continue to increase through the late-morning
and afternoon, with gust speeds peaking between 30 and 35 kts. Gust
speed and frequency will decrease after sunset, but gusts will
remain in the prevailing TAF. Around 07Z, winds will shift from the
northwest, though there remains uncertainty regarding the intensity
of the gust speeds with this northwest push. Favored a stronger
solution and have between 25 and 30 kts in the TAF until speeds
decrease through the morning. Light and diurnal winds expected on
Sunday, with temperatures remaining below 100 degrees today and
Sunday. No operationally significant cloud cover, but expect
slantwise visibility reduction in the south and west from to nearby
wildfire smoke.

For the rest of southern Nevada, northwestern Arizona and
southeastern California...For the 18Z Forecast Package...South-
southwest winds will continue to increase through the late-morning
and afternoon, with gust speeds peaking between 30 and 35 kts for
Las Vegas Valley and Colorado River Valley TAF sites... from the
north-northwest for KBIH... and from the west with speeds around 40
kts for KDAG. Gust speed and frequency will decrease after sunset
before northwesterly winds pick up between 06 and 08Z in the Las
Vegas Valley and between 12 and 14Z in the Colorado River Valley. No
operationally significant cloud cover, but expect smoke-related
visibility reductions at KBIH and KDAG overnight and slantwise
visibility reductions for all other TAF sites in the south and west
from nearby wildfire smoke.
