.DISCUSSION...
As the Garnet Fire in the southern Sierra continues to rage, smoke
aloft will impact portions of Mono and Mineral counties.
Visibility reductions remain possible with a Dense Smoke Advisory
out until 11 AM this morning. For air quality details, please
visit fire.airnow.gov.
A low pressure system off the coast of northern California will
push inland today and will stall over the area for the majority of
the week. This will bring our first taste of fall-like weather
with afternoon highs dropping into the mid 70s and 60s for the
valleys and Sierra communities, respectively. Accompanying the
cooler temperatures will be daily chances for showers and
thunderstorms as well as breezy afternoon winds.
Showers today will primarily be isolated to the Basin and Range,
and will initiate late afternoon (after 4pm), continuing
overnight into the morning hours. CAM guidance has showers and
thunderstorms firing Wednesday as early as noon, with daily
chances again Thursday. Storms will primarily start along the
Sierra and in NE CA. As of now, Wednesday looks to be the best day
for widespread shower and storm coverage; chances drop Friday and
even further Saturday.
Looking towards the weekend, brief ridging will allow high
temperatures to push into the low 80s for W NV and the mid 70s
for Sierra communities. As previously mentioned, shower chances
also diminish. However, the reprieve will be brief as a shortwave
trough off the coast of California marches inland overnight
Saturday and into Sunday. Shower chances return Sunday with
slightly cooler temperatures as well.

.AVIATION...
VFR conditions expected for all terminals except KMMH today.
Typical afternoon gusts up to 20-25 kts are expected today as
well. Showers with the occasional lightning strike may impact
Sierra terminals this afternoon (KTRK and KTVL), though confidence
remains low.
KMMH will continue to likely see LIFR/IFR conditions, primarily
due to smoke infiltrating from the Garnet Fire. As winds in the
afternoon increase, conditions may raise to MVFR. Slantwise
visibilities will continue to be impacted as the fire continues
to produce smoke.
