Area Forecast Discussion
National Weather Service Sacramento CA
933 PM PDT Mon Oct 24 2016

Wet and unsettled weather will occur this week as several weather
systems transit the area.


Rain continues this evening over most mountain areas with showers
throughout most of the valley. Models indicate the front continues
to be near Sacramento overnight with chances of rain while most of
the rain will remain north of the area. Rainfall amounts around
the Sacramento area are expected to be light through Tuesday
morning with maybe around a tenth of an inch. Snow levels continue
to be very high and a non factor in travel over the crest.

The system will start to lift northward Tuesday afternoon then
even more Tuesday night keeping chances of rain or showers well
north of the Sacramento region and over the northern portions of
the interior valley and mountains.

Wednesday brief ridging will occur over the area to bring us a dry
day. The next system will move into the area on Thursday spreading
rain into the region from the southwest and lifting it northward
over the interior. This system should bring greater amounts of
rain for the valley. Snow levels will still be very high and a non
factor for travel over the crest of the Sierra Nevada.



Unsettled weather for the end of the work week into the weekend.
The GFS, European, and Canadian models are in surprisingly good
agreement handling the entrainment of moisture from current
Hurricane Seymour into the westerlies. The odds of precipitation
are good across the region Thursday night into Friday, but the
amount of rainfall is currently highly uncertain.

Some residual moisture looks to keep showery weather going across
portions of Northern California Saturday. Models are coming into
better agreement with another wave on Sunday. A respectable amount
of precipitation is now forecast with that system, with snow
levels lowering below mountain pass level. Showers are likely to
continue into Monday.




VFR/MVFR conditions across the region as a weather system lingers
over the region.  South winds 10 to 20 kts with local gusts up to
25 kt will diminish to 5 to 15 kts tonight and Tuesday.
