.KEY MESSAGES...

* Northwest flow aloft will continue to bring periods of north
  winds and cooler temperatures to the region through the week.

&&

.DISCUSSION...through the weekend.

Ensemble guidance has us under a northwesterly flow pattern for the
first week of December. This keeps the region dry with precipitation
chances below 10% everywhere except far northeastern portions of
Lincoln County. Temperatures fluctuate within a few degrees of
seasonable values, warming slightly over the weekend. First freezes
are likely (70%) Tuesday morning in eastern Inyo, northeastern
Clark, and central Mohave counties where Freeze Warnings are in
effect. As systems pass by, periods of increased northerly breezes
can be expected. Gusty conditions continue in the lower Colorado
River Valley today with gusts generally 25-40 mph. Another round
of gusty conditions is forecast Wednesday and Thursday as a
secondary system moves through midweek. Widespread gusts of 20-40
mph are anticipated.

.AVIATION...For Harry Reid...For the 00Z Forecast Package...Now that
winds have weakened, they are expected to return to their typical
patterns, favoring a westerly direction at night and an easterly
