Area Forecast Discussion
National Weather Service Sacramento CA
910 AM PDT Sun Oct 23 2016

Cooler with periods of wet weather as a couple of systems will
bring chances of rain and high elevation snow this week.



A trough of low pressure remains off the west coast today and
will continue to spread some high clouds over the area. The
interior will stay dry but temperatures will be a little cooler
today then yesterday.

The models continue to show the earliest any rain near our area
will be Monday morning along the coastal range. Monday afternoon
some mountains and Sacramento valley may start to see some rain.
The GFS is a little bit faster and wetter than the NAM. The NAM
does not bring any rain to the Sacramento area until late Monday timing and rainfall amount issue still persist.
Some areas may not get any rain over the Northern San Joaquin
Valley. The best chances continue to look to be along the
northern coastal range and over the northern half of the
Sacramento valley and surrounding mountains.

The system still looks like it will get stretched out over the
region and weaken as it tries to move onshore and push southward
on Monday with again the GFS indicating more rainfall than the NAM.
No major impacts are expected with this storm. Snow levels will be
high so any new snow will mostly be over the peaks. Breezy
conditions should develop late tonight over the northern areas
and on Monday for everyone else. Locally windy conditions are
still possible over the far north end of the valley and over the

The system will start to lift northward slightly on Tuesday then
even more Tuesday night keeping chances of rain or showers 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 with some chances of precipitation developing along the
northern coastal range Wednesday night.



Unsettled weather forecast to continue later next week as NorCal
will remain between the trough over the eastern Pacific and
ridging over the Rockies. Snow levels expected to remain rather
high the potential for entrainment of deeper moisture up from the
south in this pattern.


VFR conds prevail next 24 hrs with SCT-BKN250. Generally light
winds under 10 kts at TAF sites.
