Area forecast discussion 
National Weather Service Sacramento California
400 am PDT Tue Oct 25 2016

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


weakening cold front has stalled out across the northern third of
California with showers continuing from the Bay area up through
the Sacramento region into the northern Sierra. Rainfall amounts
over the past 24 hours have varied from a few hundredths of an
inch in the Sacramento area to over an inch at the north end of
the Sacramento Valley, while much of the feather river basin has
seen around 2 to 3 inches. Temperatures are mild ranging from the
40s in the mountains to the 50s to mid 60s elsewhere.

As the next system develops off the coast, the weakened cold
front will lift back to the north today and be absorbed as a warm
front resulting in generally lighter amounts of precipitation by
this afternoon. Precipitation is expected to retreat further to
the north and west tonight, with most of the area seeing a return
to drier weather Wednesday into early Thursday.

Another wet system is forecast to bring more widespread rain on
Thursday and Thursday night - perhaps a short break on Friday -
then another system Friday night. Snow levels will remain high
with accumulating snowfall expected to be limited to just the
highest peaks.


Extended discussion (saturday through tuesday)
active weather pattern will continue for much of the extended
period. Models in general agreement altho vary just a bit in
timing of each wave and precip amounts. Friday's wave will begin
to shift east on Saturday with a few showers lingering across
higher terrain and portions of the area. Another wave will move
onshore from the Pacific on Sunday into early Monday. This wave
could be fairly wet, with snow levels lowering below major pass
levels during the day. This will be something to watch going
forward as it may impact travel over the mountains Sunday. Brunt
of storm will shift east on Monday with showers lingering across
higher terrain. Looks like a decent probability that active
pattern will continue past Monday. GFS suggests additional systems
every 1-2 days between brief ridging while European model (ecmwf) not quite as
robust. Below normal temperatures will rule through the period. Ceo


IFR conditions across the northern SAC valley early this morning
will gradually improve throughout the day. Showers will taper off
in most locations this morning, though a few may linger across
northern state. VFR conditions otherwise for rest of the valley
terminals. Winds 5 to 15 kts.
