.KEY MESSAGES...

* Gusty southwest winds and increased fire danger expected through
  mid-week.

&&

.DISCUSSION...through Friday.

Latest water vapor imagery shows that troughing has begun to take
hold over the western US, and models indicate it will linger through
mid-week. The height falls associated with this system bring
temperatures back to seasonable values for several days, with highs
of 80-95 degrees in the southern Great Basin and 90-105 across most
of the Mojave Desert. PoPs remain scant (less than 10%) in our
forecast area due to meager moisture. The main story with this
trough continues to be the gusty southwest winds and increased fire
danger. The fire aspect is discussed below in the Fire Weather
section, but outside of that, wind impacts will likely be confined
to the local lakes (mainly Mead and Mohave). A Lake Wind Advisory is
in effect today due to winds 20-25 mph and gust up to 40 mph causing
waves of 2-4 feet. Monday and Tuesday present the next best odds (40-
50% chances) of boating impacts. As we get into the 2nd half of next
week, ensemble guidance shows the trough lifting to our northeast,
allowing winds to relax, temperatures to rise, and dry conditions to
persist.

.FIRE WEATHER...Expecting widespread southwest winds of 15-25 mph
with gusts
up to 40 mph today. 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 northwestern 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 and
produces similar winds. Winds are forecast be most widespread on
Monday, becoming confined to far southeastern NV and northwestern AZ
on Tuesday. A Fire Weather Watch remains in effect for all of our AZ
zones and most of our NV zones on Monday and Tuesday.
