.KEY MESSAGES...

* Strong winds start today and continue into Friday with fire
  weather, recreation, travel, and aviation concerns.

* Temperatures are slightly cooler today, with isolated areas of
  moderate HeatRisk.

* Continued cool, dry pattern will continue through at least the
  start of next week.

.DISCUSSION...

* The main story through the end of the week will be the trough
  that`s bringing in some strong gusty winds. Strong west to
  southwest winds are en route to kick up by the afternoon and
  continue through much of the evening. There will be a bit of a
  lull in the wind action by Friday morning before another, strong
  round of winds arrives. Widespread 30-40% chances of peak gusts
  exceeding 45 mph. For wind prone areas along US-395/I-580 in
  western Nevada, eastern Lassen and Mono counties, gusts will near
  50-60 mph on Friday. Sierra ridge winds will be anomalously strong
  (at least for summertime) with gusts 60-80 mph. Plan on several
  days of recreation impacts for area lakes, turbulence for
  aviation, and potential road restrictions due to high winds.
  Please see the Fire Weather section below for fire weather
  concerns.

* Little to no potential for meaningful rain with this trough
  (bummer), but there is a 15% chance of showers and storms today
  for northeast CA and far northwest NV. As the upper trough digs
  southward on Friday, there will be a 30-60% chance for light rain
  along a line north of I-80, from Susanville through Gerlach and
  Pyramid Lake. A 5-10% chance of thunder for far northern Washoe
  county, but that is about it. The higher elevations of the Werner
  Mountains in Modoc County and far northern Washoe County may see a
  mix of rain/snow Friday night into Saturday morning, but
  accumulations are unlikely.

* Much cooler air arrives with this strong trough, bringing highs
  down to the upper 70s to mid 80s for western Nevada and 50s and
  60s across the Sierra for Friday. By Saturday, it cools off even
  more with temperatures in western Nevada dropping to the 60s, and
  some Sierra locations may see highs in the 40s. Temperatures will
  moderate a touch for Sunday with a more substantial warm up by
  Monday as we return to widespread 80s for western Nevada and 60s
  to 70s for Sierra communities.

* Looking ahead, general troughiness stick around through the middle
  of next week maintaining cooler temperatures and typical afternoon
  breezes. Warming begins to return toward the end of next week,
  approaching our seasonal norms.

.AVIATION...

* Westerly winds increase today with widespread wind speeds 15-25
  kts and gusts to 35 kts.

* Stronger winds arrive Friday as FL100 winds ramp up to 35-50 kts
  between Fri 6z-Sat 3z. Plan on local ridge winds 55-65 knots
  and surface wind gusts 25-35kts. Risk of LLWS and turbulence
  arrives with this uptick in strong winds for today and again on
  Friday. Otherwise, VFR conditions will prevail with
  precipitation potential remaining well north in Oregon.

* Westerly winds will switch to northwesterly winds Friday night.
  Plan on north-northwesterly breezes for much of Saturday as the
  trough sags southward through the region.

.FIRE WEATHER...

* There are no changes to the current Red Flag Warning for today and
  Friday.

* Plan on widespread wind gusts up to 45 mph for leeside valleys
  today, with wind prone areas getting up to 60 mph and ridges as
  nearing 70 mph. After a bit of a lull overnight, widespread gusts
  resume on Friday, with widespread gusts to 50 mph, wind prone
  areas to 65 mph and ridge gusts to 80 mph. These wind gusts
  combined with low relative daytime humidity (5-15%) and poor
  overnight recoveries around 20-30% will result in multiple hours
  of critical fire conditions.

* Breezy winds will stick around on Saturday behind the cold front.
  Colder temperatures with winds decreasing will moderate critical
  fire conditions for much of the region, but we may still have some
  localized critical conditions for far southern Mineral and Mono
  counties. For now, we will continue to headline gusty winds and
  dry conditions for those areas on Saturday and monitor the need
  for additional products.
