.DISCUSSION...
Cooler air has spread across CA-NV after Monday`s initial cold front
passage. Most of the storm activity has diminished, although narrow
bands of showers continue to push across the Sierra into Mono
County, and across northeast CA.
For today through Thursday morning, the main low is projected to
remain offshore from the Pacific NW coast, while weak shortwaves and
narrow bands of Pacific moisture continue to move across the Sierra.
Most of the precip will remain near the Sierra and into northeast CA
but overall amounts in these areas should be light, ranging from a
few hundredths of an inch to 0.25" each day through Wednesday. Snow
levels dip to between 9000-9500 feet this morning so a few flurries
or a light dusting may show up on higher peaks around the Tahoe
basin. For lower elevations, mostly cloudy conditions will prevail
with more sparse showers producing minimal measurable rainfall
(trace amounts up to less than 0.10") through early Thursday. Winds
on both Lake Tahoe and Pyramid Lake will edge upward into Lake Wind
Advisory levels again this afternoon as 700 mb flow near 30 kt and a
weak shortwave passage will lead to another day of chilly and choppy
lake conditions.
For Thursday-Friday, the low finally heads inland with more of the
guidance favoring the center dropping southward across CA/NV.
The timing and track still have some details to be sorted out, but
given the increased forcing associated with this low`s passage,
shower and isolated t-storm chances are poised to increase again.
Currently, the highest probabilities (25-40%) extend from the
eastern Sierra northward across west central NV, with lesser chances
extending across the Reno-Carson-Tahoe areas and northward to Lassen
County and the OR border. We may see a brief drying trend by this
weekend, although another weak low could drop in from the north and
keep low-end shower chances going.
Temperatures will remain below average for the upcoming week with
highs mainly in the mid 60s-lower 70s for lower elevations and upper
50s-mid 60s for Sierra communities. Chilly overnight lows will
prevail with lows mainly in the 30s near the Sierra and 40s for
lower elevations. There is increased potential for freezing temps in
Sierra valleys and mid-upper 30s with patchy frost for typically
cooler lower elevation sites by this weekend when overall cloud
cover decreases. MJD

.AVIATION...
Breezy winds with gusts around 25 kt will return this afternoon,
then ease back to near 20 kt for Wednesday afternoon for the Tahoe
area and western NV terminals, with slightly lower winds for KMMH.
With FL100 winds in the 35-45 kt range at times through Wednesday,
areas of mountain wave turbulence and occasional LLWS will continue
around the Tahoe area and far western NV terminals.
While mainly VFR conditions prevail through midweek, cloud cover
will persist especially for the Tahoe area and far western NV
terminals. Occasional light rain showers may bring brief reductions
to MVFR CIGS mainly for KTVL/KTRK, along with mountain top
obscurations at times which could extend into far western NV. MJD
