.DISCUSSION...
Low-level water vapor imagery shows the first band of moisture
pushing into the Sierra this afternoon with isolated showers on
the west side of the Sierra crest north of the Tahoe Basin
already. As that moisture builds in, expect cloud cover to
increase. A second band is just now off the coast of northern
California and is expected to move into the area by late this
afternoon into the early evening hours. Light showers today will
be confined to the Sierra and the Sierra Front, primarily in and
around the Tahoe Basin. Expect similar conditions Wednesday in
terms of showers with light accumulations (up to 0.1").
Those two bands of showers will bring increased wind gusts this
afternoon. Expect gusts up to 40 mph for much of the area.
Additionally, recreation and travel impacts are expected with
choppy lake conditions and bumpy flights.
Afternoon highs remain below normal through much of this week with
highs in the mid 70s and low to mid 60s for valleys and higher
elevations, respectively. As of now, Friday looks to be the
coolest day of the week, possibly bordering on "chilly," with a
current high of 64 in Reno. Sierra communities can expect to drop
into the mid 50s Friday. As such, overnight lows are dropping,
with more Sierra communities seeing lows flirting with freezing by
this weekend. Speaking of freezing, snow levels will remain around
9500 ft through the rest of today; cameras up near Mammoth have
been showing some flying snowflakes today!
The low pressure system that is bringing in the aforementioned
moisture is spinning off the coast of the Pacific NW. As the week
progresses, that low will move further south and inland into
northern California by Thursday. This has thus increased the
chances and areal coverage for showers and thunderstorms Thursday
and Friday with a 30-60% chance areawide. Saturday and beyond, we
look to stay cool but expect drier conditions.

.AVIATION...
VFR conditions expected through much of this week except where
brief, heavy showers may drop CIGS/VIS to MVFR briefly, primarily
for KTRK/KTVL today and tomorrow. Showers may also bring mountain
obscurations. Otherwise, expect gusts up to 30 kts today for both
Sierra and Sierra Front terminals.
With increased wind gusts, pockets of mountain wave turbulence and
LLWS will be possible, primarily for Sierra Front terminals.
