AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SACRAMENTO CA
915 PM PDT Tue Sep 2 2014
Cooling overnight and Wednesday then near normal daytime highs
Thursday through Saturday. Dry weather continues.
Moderate to Strong delta breeze is bringing cool air into the
central valley this evening. Temperatures are most noticeably
cooler around the delta and Sacramento area this evening with
temperatures running up to 20 degrees cooler this evening than
last night. Marine layer is up to around 2000 feet with a strong
push through the delta ongoing. Stratus will likely spread into
the Sacramento region late tonight and Wednesday morning.
Temperatures overnight in the delta and Sacramento area will cool
into the mid to upper 50s. Elsewhere in the valley temperatures
will mainly cool to the lower 60s.
The strongest cooling this week looks like it will be tonight and
Wednesday for the Sacramento region with Thursday being the
coolest day for area`s well inland including the mountains. This
will also be the strongest the delta breeze should be the next
several days and at this time probably our best chance of getting
any stratus into the inland valley. Surface high pressure building
over Oregon will likely bring light northerly flow the next couple
of days to the interior after tonight.
A baggy trough will gradually deepen over the west coast to bring
some synoptic cooling later this week. Onshore flow does not look
that strong but at least should be weak onshore through the delta.
Temperatures look to be near seasonal normals into the weekend.
.Extended Discussion (Saturday through Tuesday)
Persistent weak troughing aloft into NorCal will bring minor
cooling...near to just below normal. We have kept the forecast
dry. Mainly onshore winds with morning marine stratus
infiltrating to I-680 and Cordelia. JClapp
General VFR conditions with MVFR ceilings approx 015 into the
southern Sacramento Valley Wed morning. Fort Ord profiler shows
steady marine layer increase up to 2000ft and Bodega Bay is up to
1600ft as of 21z Tue. Less than 30% chance of stratus at KSCK,
but ceilings may encroach toward KSMF from SE. JClapp
