.DISCUSSION...
Strong low pressure in the eastern Pacific continues to pivot
towards the region per latest moisture-channel imagery. This feature
will be responsible for ushering in fall-like weather this week,
featuring breezy afternoon winds, midweek showers and t-storms, and
much cooler temperatures.
Winds will become breezy in the afternoons through Tuesday in
response to the approaching low pressure area. Southwest to west
gusts peak around 25-30 mph today, increasing to 30-40 mph Monday
afternoon. Locally enhanced gusts of 40-50 mph will be possible in
wind prone areas. Be prepared for wind impacts to travel and
recreation early this week. Areas of elevated fire weather
conditions are likely each day with holdover fires possibly flaring
up amid increased winds.
Our ongoing cooling trend continues through Wednesday and will yield
fall-like temperatures from midweek onward. Daytime highs will only
reach the 60s and 70s after Monday with freezing overnight lows in
the Sierra around midweek. Meanwhile, chances of showers and
thunderstorms trend upward as soon as Monday -- mainly from the
Tahoe Basin into NE California -- and spread eastward Tuesday
through Thursday. Wednesday and Thursday will likely feature the
greatest coverage of showers and thunderstorms with widespread odds
of 30-60%. In fact, it may even be cold enough to allow snow
flurries on highest Sierra peaks on both days! Shower and storm
chances linger into the weekend, but a drying trend will reduce odds
and coverage. Temperatures will also slowly warm as we head into the
weekend, but will remain below average through the weekend.

.AVIATION...
The primary weather concern today will be SW/W surface gusts of 20-
30 kts during the afternoon. Periods of LLWS impacts are likely
through the afternoon at Sierra Front terminals where winds will be
strongest. FL100 winds also increase this evening, perhaps resulting
in mountain wave turbulence overnight. Winds increase Monday
afternoon, resulting in additional LLWS impacts and mountain wave
turbulence.
Otherwise, increased smoke production from the Garnet fire will
further impact slantwise visibilities -- especially at KMMH where
smoke will be most concentrated.
