.DISCUSSION...
This morning`s visible satellite aboard GOES-West shows that
smoke has settled in across much of Mono, Mineral and southern
Lyon counties this morning as the Garnet Fire continues. A Dense
Smoke advisory has been issued for the area, and your local air
quality can be monitored at fire.airnow.gov. Smoke will linger
into the afternoon, when southwesterly breezes pick up. Gusts may
reach 25-35 mph for valleys, with ridge winds approaching 50-60
mph. As these winds will cause travel and recreation concerns, a
Lake Wind Advisory has been issued for both Lake Tahoe and Pyramid
Lake today. This increase in breezes will taper after sunset,
allowing smoke to filter back into the Mono/Mineral/S.Lyon valleys
by morning. We will continue to monitor the fire and associated
smoke as the week progresses.
The breezes we will see tonight are a precursor to an incoming low
pressure system currently churning in the Pacific off the northern
California coast. Shower chances will begin to increase across
northern California this afternoon and evening. This feature will be
responsible for much of the sensible weather this week. Shower
chances will reach a maximum of 40-70% across northeastern
California and northwestern Nevada by midweek. Additionally, this
low pressure is bringing in some cooler temperatures, especially for
our neighbors in Sierra communities. Overnight lows this week will
hover near freezing for Sierra valleys, with a few snowflakes
possible on the highest peaks Wednesday, Thursday and Friday
mornings, amounts will be light.
As the weekend approaches the chances for showers will taper, the
temperatures will rebound and the winds will relax. Saturday looks
to be the day if you are interested in dry, clear skies, average
temperatures and light winds. Sunday, another opportunity for
showery weather arrives as a series of shortwaves takes aim at our
region. HRICH

.AVIATION...
* Most area terminals expect VFR conditions today, the primary
  weather concern today will be southwest/west surface gusts of
  20-30 kts during the afternoon. Mountain wave turbulence and
  LLWS impacts will also be likely as well with these winds.
  Otherwise, mostly dry conditions are expected across the region
  today.
* KMMH looks to be the outlier TAF site that will see sub-VFR
  conditions mostly due to smoke filtering into
  Mono/Mineral/S.Lyon counties from the Garnet Fire in CA. There
  may be a brief break between 8/22Z-9/04Z when winds pick up
  allowing for VFR conditions at KMMH, but models show smoke
  returning and lowering the visibility once again tonight.
  Increased smoke production from the Garnet Fire will also
  further impact slantwise visibilities across the
  region.-078/HRICH
