Synopsis
Weak system brings a slight chance of light showers over the
mountains Friday night into early Saturday, otherwise dry through
early next week. Breezy to windy conditions forecast this weekend,
resulting in increased fire concerns.

Discussion (today through Monday)
Upper level high pressure over the region overnight began to show
signs of degradation as a shortwave trough approached in the
eastern pacific. Water vapor imagery showed increasing amounts of
moisture streaming ahead of the approaching disturbance with
increasing high level clouds for northern california.

Short range models continue to be in good agreement to tracking a
shortwave trough of low pressure aloft through northern california
tonight and exiting by early Saturday. This system will bring
increasing cloud cover and some chances for light rain for the
northern mountains and high sierra elevations.

The most impactful weather will be as the system passes and
northerly winds develop Saturday. Pressure gradients across the
valley and mountains will allow gusty winds to develop. The
combination of dry fuels with a lack of recent rainfall, low
relative humidities and windy conditions will provide critical
fire weather conditions for portions of the valley and west valley
foothills mountains. Outdoor burning is discouraged.

Calmer winds will return Sunday into Monday as another upper level
high pressure system develops and returns to northern california
to provide dry conditions and above normal temperatures.

.Extended discussion (Tuesday through Friday)
models continue in agreement with a cold pacific storm system
dropping south mid-week. This system breaks down the ridge rather
rapidly and brings a few impulses of precipitation across northern
california. Current forecast reflects precip chances wed-thur with
possible pattern change. This system appears to be rather dry
with only light rain and snow amounts expected. Relatively low
confidence remains with specific system details.

Aviation
Vfr MVFR conditions across interior norcal the next 24 hours
except local MVFR ifr conditions in br for the southern sacramento
and northern san joaquin valleys. Valley winds generally below 10
knots.

Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data. Changes in harbors due to building or dredging change tides and currents and for that reason many of the locations presented are no longer supported by newer data bases. 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.
