Area Forecast Discussion
National Weather Service Sacramento CA
322 PM PST Sat Jan 14 2017

.Synopsis...
Fairly dry conditions through Monday. Moderate amounts of
precipitation is possible by midweek with renewed flooding
concerns as the wet pattern could extend into the weekend.

&&
.Previous Discussion...
Dense fog is expected to start to form earlier tonight than last
night so by 9 to 10 pm some dense fog could be setting up in
places from around Marysville southward in the valley. Fog will
likely be a problem the next several days.

The next system looks like it will start moving into far Northern
California Tuesday evening spreading southward overnight and on
Wednesday. Snow levels will be high initially but lower on
Wednesday below pass levels. Some gusty winds, around an inch or
so in the valley with up to a couple of inches for the foothills
and mountains.

&&

.EXTENDED DISCUSSION (Wednesday THROUGH Saturday)

Models still showing that another atmospheric river could be
aimed for the West Coast next week. Models indicate that the
moisture plume should start impacting NorCal sometime early
Wednesday. Heavier and more widespread precipitation is forecast
to begin by Wednesday afternoon and continue into early Thursday
before turning more showery.

Looks like showery weather will continue into early Friday, but
then another wave of widespread precipitation arrives during the
day on Friday. Both systems are forecast to have moderately low
snow levels and look to move through the region fairly quickly, so
flooding not expected to be as significant or widespread as
earlier this week.
&&

.AVIATION...

Mainly VFR conditions the next 24 hours except areas of MVFR with
local IFR visibilities south of KSAC until 18Z.
&&

.STO WATCHES/WARNINGS/ADVISORIES...
None.
