Monday should be prepared for winter weather conditions at times.
Slick roads are possible at lower elevations from wet leaves and
clogged drains.

A third of an inch of rain over the northern Sacramento Valley, a
few hundredths of an inch for the central to southern Sacramento
Valley. A tenth to 3 quarters of an inch in the mountains.

...STRONG WINDS THIS WEEKEND WITH SNOW OVER THE PASSES BY LATE
SUNDAY...

A potent Pacific storm will move inland this weekend bringing
rain, mountain snow, and gusty winds. The winds will begin
Saturday and continue through Sunday. Precipitation will begin as
rain, even over Sierra passes, as snow levels start high. Snow
levels will begin to fall Sunday with snow over the passes
possibly by sunset. Expect holiday weekend travel impacts due to
winds and snow over the passes. Some details follow:

* WINDS: Strong, gusty southwest winds are expected from late
Saturday morning through Sunday afternoon. Winds may abate
somewhat over Saturday night in lower valley locations, but
they will remain strong along the foothills and over the ridges.
Wind gusts of 60 mph or more are possible along portions of the
395 corridor and Sierra ridge gusts will likely exceed 100 mph.

* PRECIPITATION: Light rain is likely over the mountains by
Saturday evening north of I-80 before gradually spreading
southward into Sunday evening. Snow levels will also gradually
fall during this time before crashing late Sunday night as a
strong cold front moves through the region. Precipitation will
end Monday morning behind the front.

* SNOW LEVELS: Starting near 9000 feet Saturday afternoon before
falling to 5500 feet for Lassen County, 7000 feet for the Tahoe
Basin, and 8000 feet for Mono County by late Sunday afternoon.
Snow levels will crash Sunday night and fall to near the lower
valley floors as the precipitation ends. While it is too early
to predict snowfall amounts, accumulations are likely for the
Sierra passes with light accumulations possible as low as 5000
feet. Be prepared for major travel delays over Sierra passes due
to slick and snow-covered roads.
