area forecast discussion
national weather service sacramento ca
325 am pdt Fri sep 20 2019

Synopsis
Dry and mild weather today and Saturday. Another system skirts
the area Sunday bringing precipitation chances to the mountains.

Breezy north winds possible early next week.

Discussion
Clear skies cover the region early this morning. Current
temperatures are colder in the mountain valleys where readings are
in the lower 30s, but a little milder across most of the remainder
of interior norcal where the mildest readings (lower 60s) are
across the northern sacramento valley.

The mid-week trough lifts off to the northeast today as ridging
moves into norcal from the eastern pacific. Highs today are
will be around 5-10 degrees warmer compared to Thursday with
another 5 degrees or so of warming expected on Saturday when the
warmest valley temperatures will be in the lower 90s. Locally
breezy north winds in the sacramento valley.

Another open-wave system will pass to the north on Sunday and Sunday
night before closing off over the great basin. This will bring
another chance of showers over the mountains followed by the
potential for breezy northerly winds in the central valley on
Monday.

Extended discussion (Tuesday through Friday)
Pronounced height falls shifting southward into the desert
southwest on Tuesday will allow offshore ridging to extend back
into northern california. While ensembles show a potential for
this upper low to linger, it should remain far enough south to not
be influential on the forecast. Tuesday and Wednesday appear to
be the warmest days next week given the building heights from the
eastern pacific upper ridge. Nocturnal east-northeasterly flow off
the sierra should keep the typical thermal belts quite mild
overnight as lows stay in the upper 60s from oroville northward.

Ensemble means support a shift in the synoptic pattern by as early
as Thursday as broad troughing re-establishes itself over the
western u.S. Consequently temperatures will lower by around 10 to
15 degrees with valley highs possibly remaining in the upper 70s
by next Friday (sep 27). GEFS ensemble plume diagrams show quite a
bit of diversity in the members but trends depict decreasing
temperatures as shown in the forecast. Lowering heights should
also bring additional cloud cover into the region as well as a
chance for mountain showers. Details will change but climate
forecasts continue to favor below average temperatures late next
week, possibly sticking around until the end of the month. ~bro

Aviation
Outside of some high clouds lingering over the mountains as well
as krdd and krbl, much of the region is clear. TAF sites will see
northwest to northerly flow, becoming locally gusty between 18z
and 03z. Northeasterly downslope winds pick up by the evening over
the sierra and adjacent foothills. ~bro

Sto watches warnings advisories None.

For example, there is very little tidal current data in newer data bases so current data is likely wrong to some extent. This data is NOT FOR NAVIGATION. See the XTide disclaimer for details. In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
