Area Forecast Discussion
National Weather Service Sacramento CA
104 PM PST Sun Nov 19 2017

.SYNOPSIS...
Dry weather through late tonight. Weather disturbance will bring
chances for rain spreading across NorCal late tonight through mid
week, mainly for the mountains and the Sacramento valley. Chances
for rain over parts of the interior will continue through next
weekend.

&&

.DISCUSSION (Today through Wednesday)...
The ridge of high pressure that brought us nice weather this
weekend will weaken as a system moves into the Pacific Northwest
on Monday. The models are in fairly good agreement with bringing
light precipitation across the interior on Monday, mostly during
the daytime. Snow levels will be very high above pass levels and
precipitation amounts light so no travel problems are expected
other than some slick roads.

A low pressure system will move into the gulf of Alaska behind
the system in the Pacific Northwest. This will help to keep most
precipitation focused in the Pacific Northwest for Tuesday and
Wednesday and some ridging over California. Some light impulses
around the base of the trough may bring some showers along the
coastal range and over Shasta County as times. However, for the
most part things should remain dry most of the time for that
area.

.EXTENDED DISCUSSION (Thursday THROUGH Sunday)

Overall not expecting much travel issues for the extended period
and holiday week but you may have to deal with wet roads at
times. A front will be working south through NorCal Thursday night
into Friday. This will bring a chance for light showers with the
best chances in the higher elevations in the northern part of the
CWA. Snow levels will be high with no snow accumulation expected,
rain totals also look to remain light. The front then is going to
stall out over NorCal into next weekend and this will keep shower
chances in the forecast. With the weak forcing it`s hard to
pinpoint timing and placement but anything we see will be light
and scattered. Snow levels look to remain high with no snow
expected. Temperatures stay mild throughout the extended period
running 5-10 degrees above average with the warmest days Thursday
and Friday.
