.KEY MESSAGES...

* Gusty southwest winds and increased fire danger expected through
  Tuesday.

&&

.DISCUSSION...Today through Saturday.

As the lead shortwave within the western US trough lifts
northeast today, winds weaken slightly and become more focused
along/southeast of I-15. Tomorrow, the next shortwave moves into
the region and brings a renewed shot of gusty southwest winds.
Like today, the wind emphasis on Tuesday shifts mainly into
northwestern Arizona. The main concerns with the winds each day
are the increased fired danger (discussed in the Fire Weather
section below) and periodic lake/boating impacts. Best chances
(70%) for the latter are on Monday when a Lake Wind Advisory is in
effect for Lake Mead and Lake Mohave. By mid/late week, ensemble
guidance has the parent trough lifting and weakening, leading to
height rises and the return of zonal flow. At the surface, this
translates to lighter breezes and warming temperatures. Expect a
transition from seasonable temperatures to highs 6-10 degrees
above normal. Precipitation chances remain below 10% across the
area throughout the forecast period.

.AVIATION...For Harry Reid...For the 06Z Forecast Package...Breezy
south-southwesterly winds will continue overnight before winds back
south-southeast after sunrise. Expect gusty southwest winds to pick
up through the afternoon with speeds between 25 and 30 kts and
directional variability between 190 and 230. May initially see a few
gusts from 160 to 190 before they fully shift southwesterly. Gust
speed and frequency will decrease after sunset. No operationally
significant cloud cover. High temperatures will hover just below 100
degrees.

For the rest of southern Nevada, northwest Arizona and southeast
California...For the 06Z Forecast Package...Gusty south-southwest
winds will pick up across the Las Vegas Valley and Colorado River
Valley with gust speeds peaking between 25 and 30 kts. KBIH can
expect elevated diurnal winds. KDAG will gust from the west, with
minor lulls in speed overnight. No operationally significant cloud
cover.
&&


.FIRE WEATHER...Strongest winds and critical fire weather conditions
become focused in northwestern AZ today. A Red Flag Warning is in
effect until 11PM this evening for AZ101, AZ102, and NV466 fire
weather zones. Southwest winds of 15-25 mph and gusts around 35
mph are expected in this area, with lighter breezes to the west.
More widespread gusty conditions likely on Monday, resulting in
the upgrade to a Red Flag Warning across northwestern AZ and most
of southern NV. Winds have trended lower across southern NV on
Tuesday, and thus the Fire Weather Watch has been cancelled for
these zones. However, winds look sufficient across northwestern AZ
on Tuesday, so the watch has been upgraded to a Red Flag Warning
for Tuesday as well. Afternoon RH values are forecast to be 5-15%
through Tuesday with poor overnight recoveries.

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