Synopsis
Scattered mountain showers today with light snow higher
elevations. Another round of rain and snow Friday afternoon
through Saturday with enough mountain snow for travel impacts.

Dry Sunday then more rain and mountain snow early next week.

Discussion
Morning update: cyclonic flow from the upper low NW of klas
resulting in some cloudiness crossing the sierra crest through the
"backdoor". This cloudiness will gradually erode dissipate in our
cwa as the upper low moves right over klas by 00z Fri and cyclonic
flow weakens over the NRN sierra. Today will be a dry sunny day over
the rest of our cwa, and dry wx will last into Fri morning as the
ern pac ridge axis moves inland. But, by Fri afternoon and evening
precip will once again spread over interior norcal as mar wx
continues to roar like the proverbial lion. Looking at the extended
forecasts and plumes, it looks as if mar wx will continue to roar
through most of next week before it GOES out like "a lamb". Spring
wx in norcal is making a slow arrival this year. Jhm

Previous discussion
Negative tilt upper trough over the state this morning brought a few
light showers to the northern sacramento valley earlier this evening
as well as some light shower activity over the northern sierra. Most
showers have ended but a slight threat of mountain showers will
continue today as the upper low shifts eastward into the the great
basin. Daytime highs will reach near normal today in the central
valley under mainly sunny skies while the mountains remain mostly
cloudy. Most areas will see dry conditions tonight under brief upper
level ridging before the next pacific frontal system pushes onshore
Friday morning. By mid day Friday, areas west of the sacramento
valley should be seeing light precipitation if current model
projections hold. By Friday afternoon, the frontal band shifts
inland over norcal with precipitation expected over the sierra
cascade range. Travel impacts are likely over the sierra during the
Friday to Saturday afternoon timeframe as the moderately cold for
the season storm system will likely bring several increases of
snowfall below pass levels. Have therefore issued a winter weather
advisory to deal with likely travel difficulties. Light
precipitation at the lower elevations will likely only bring minimal
issues. The main upper trough is forecast to move through Saturday
afternoon and night for continued shower activity over the sierra
cascade range. Snow levels at this time are forecast to drop to 4000
feet before precipitation drops off Saturday night.

Upper ridging will make Sunday a fairly dry day with mainly fair
skies warming daytime highs to near or a little above normal. This
dry period should make Sunday a fairly good travel day. This break
will be fairly brief, however, with the next pacific system
pushing inland by Sunday night.

.Extended discussion (Monday through Thursday)
an unsettled and cool pattern is expected next week, with periods
of rain, mountain snow and breezy winds.

Confidence is good that wet weather will spread across the area
Monday, with general agreement across GEFS ensemble members and the
potential for a weak atmospheric river continues. Models are pretty
consistent in directing the best moisture over northern california,
but there is some variance in exactly where.

Additional waves with decent moisture plumes are expected to
continue through the week, bringing periods of moderate to heavy
rain, but exact timing remains uncertain. Early estimates of
precipitation are around 1 to 4 inches for Monday through
Wednesday. Snow levels continue to range between around 5000 to
6000 feet, with the potential for travel delays. Ek

Aviation
Vfr conditions are expected over the next 24 hours. Winds are
expected to generally under 10 knots. Ek

Sto watches warnings advisories
Winter weather advisory from 11 am Friday to 5 pm pdt Saturday
for west slope northern sierra nevada-western plumas
county lassen park.
