Synopsis A broad trough over the region will prolong an active
weather pattern and unseasonably cool temperatures through next
week. There will be a chance for rain on Saturday with more
widespread rain, mountain snow, and small hail possible Sunday
into Monday.

Short term Through Monday. The next upper disturbance to
impact the region is forecast to arrive on Saturday. This feature
will aid in generating showers, first across the coast during the
morning, and then interior areas by midday. The greatest precip
amounts from 0.05-0.3 inches, will occur from central humboldt
northward across del norte county. Elsewhere, precip totals will
be less than 0.05 inch. In addition, snow levels are forecast to
rise to around 2500 feet by afternoon. Thus, impactful snow
accumulations are not expected due to the combination of light qpf
and rising freezing levels.

A stronger storm system, characterized by 700 mb temperatures near -
17c, and 500 mb temperatures at or below -30c, will dig south across
nrn ca Sunday night into Monday. Snow levels near 2000 feet will be
probable as a result, and could fall as low as 1500 feet. In
addition, model guidance shows the digging trough yielding a
substantial amount of deep-layer upward vertical motion augmented by
a convective environment and westerly upslope flow. Thus, the
potential for impactful snowfall affecting mountain travel corridors
exists. In addition, forecast soundings and model hail guidance
supports small hail along the coast. Jg kml

Long term Tuesday morning through Friday. An active weather
pattern will continue for northwest california as an area of low
pressure sits over the western us. Cool and wet weather is
anticipated during this time frame. The latest set of model runs are
in better agreement about Friday day 7 in rainfall intensity;
however, the placement of the storm is not the same. Confidence
remains low on the forecast that far out.

Aviation Post-frontalVFR sunny conditions persisted across the
acv, cec and uki air terminals... As well as the entire reach of
nw california today. A middle afternoon visual Sat picture showed
a spectacular shot of snow over the region's coastal hills to the
interior higher ranges. Nwly winds were mostly light to afternoon
breezy at acv and cec especially. Clouds will begin to enter the
area from the NW in the evening and overnight as the next weather
disturbance approaches the redwood coast. North coast air
terminals will most likely slowly deteriorate Saturday morning as
rain and intermittent MVFR CIGS vis move into the region. Uki and
the more southern interior areas are expected to remainVFR
through most Friday. Ta

Marine N winds will continue to diminish this evening, but
advisory level winds will continue over the S waters through
tonight. After a period of sub-advisory winds this weekend (albeit
just barely in some areas), N winds are forecast to increase again
on Monday with gales possible over the S outer waters by Monday
night. Combined seas will build up to 17 feet in the outer waters
during this time period.

A small NW swell at around an 18 second period will gradually decay
through the day on Sunday. A more substantial NW swell will impact
the area through the forecast timeframe, with periods 8 to 10
seconds through Saturday, then 12 to 14 seconds on Sunday into next
week. Sec kr

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.
