.KEY MESSAGES...

  aviation, and recreation.

* A significant cooling trend is expected for Friday through early
  next week, followed by a gradual warm up with dry conditions.

.DISCUSSION...

Winds are already increasing along ridges and winds are expected to
be elevated throughout the day. Winds will become more widespread as
the day progresses, with gusts in western Nevada valleys reaching 30-
35 mph while ridges are gusting up to 45 mph. Watch for choppy
lakes, bumpy plane rides and recreation impacts. As such, there are
Lake Wind Advisories up for area lakes this afternoon.

Saturday will really see amplification of winds, starting early and
lingering into the overnight hours. Winds will start to increase
ahead of sunrise and keep trending gustier through the day. With the
downsloping potential developing later in the day possibly
coinciding with the timing and placement of the frontal passage, we
expect to see gusts 55-65 mph possible along wind prone slopes,
while ridges may gust to near 80+ mph, especially along the northern
Sierra. Western Nevada valleys could see gusts approaching 40-50 mph
during the afternoon hours. The winds look to stay elevated along
the ridges through the overnight hours, tapering by late morning.
This will bring aviation, recreation and travel concerns for high-
profile vehicles, as well as blowing dust near desert sinks and dry
lake beds. The winds will work to overcome any relative humidity
increases from recent showers, also bringing fire weather concerns
to be covered in the Fire Weather section of this discussion.

Temperatures will be noticeably cooler Sunday once the front passes,
leaving behind a cool end to the weekend. Temperatures will slowly
rebound into next week, with dry conditions prevailing. HRICH

.AVIATION...

* Winds are already increasing along ridges this morning, with gusts
  up to 30 kts possible. Expect LLWS and turbulence today.

* Saturday winds will increase further, with gusts to 60 kts
  possible for Sierra terminals, while western Nevada valley
  terminals will see gusts up to 45 kts possible. More LLWS and
  turbulence is expected for Saturday. HRICH

.FIRE WEATHER...

An approaching upper level storm system brings strong winds to most
of the region today and Saturday. Elevated to near critical
conditions are expected on Friday for portions of northern Washoe,
eastern Lassen, Churchill, and northern Lyon counties. The minimum
relative humidity of 10-15% will accompany winds gusting to 25-35
mph in the late afternoon and evening.

By Saturday, winds increase significantly with widespread gusts to
40-50 mph with 55-65 mph for wind prone areas. Gusty to strong winds
are expected with minimum relative humidity above 15-20%,
however, the strong winds will overcome any increase in RH.

Conditions will improve by Sunday morning as the winds very slowly
come down on Saturday night.
