Area Forecast Discussion
National Weather Service Sacramento CA
144 PM PST FRI NOV 27 2015

Mainly dry conditions into this weekend with cold morning
temperatures. The next chance for precipitation will arrive
next week.


Pesky upper level low will remain over the Great Basin into the
weekend. A few snow showers may linger near the Sierra crest
tonight into Saturday but moisture is very limited so not
expecting much activity. High pressure to the NW will allow for
cold air to continue filter into the area through the weekend.
Morning lows will hover near the freezing mark in the valley both
Saturday and Sunday morning, with temperatures a few degrees
colder on Sunday morning given lighter winds. Will let freeze
watch for Sunday morning ride. Daytime temperatures will remain
several degrees below normal. Breezy northerly winds across the
western side of the Sac Valley will decrease tonight into
Saturday although a few gusts on the order of 15-20 mph still

Next system of interest may approach the West Coast during the day
Monday. Models currently depict wave fizzling out as it moves
onshore so limited chances for much precipitation with it with
best chances across northern and western portions of the area.



Confidence is still not high in the extended forecast as the GFS
and ECMWF remain varied in their output. As things stand now, both
the GFS and EC agree that weak ridging will develop Monday night
into Tuesday for drier conditions across NorCal. Overnight Tuesday
into Wednesday is when showers could impact our region again,
though the GFS limits these showers to Shasta County while the EC
spreads them as far south as Interstate 80. A deeper trough will
move into our region on Thursday but there are timing differences
on its arrival between the models and then showers should taper
off on Friday. JBB
