Synopsis Cooler temperatures are expected across the interior
this weekend, followed by a gradual warmup the second half of the
upcoming week. Otherwise, dry weather will prevail.

Discussion Satellite imagery shows most of northwest california
cloud free early this afternoon, with an upper-level disturbance
over the region. Cooler inland temperatures have been observed
early this afternoon and are expected to persist through the
weekend. Deterministic and ensemble guidance show an upper-level
trough starting to enter the northeast pacific late tomorrow and
slowly moving toward british columbia through the middle of the
upcoming week. High pressure is then forecast to spread toward the
area from the southwest, likely leading to another warmup across
the interior during the latter part of the week. At the coast,
forecast soundings show the marine layer slowly deepening over the
next couple of days. Marine stratus and patchy fog will return on
a nightly basis, with some areas of patchy drizzle also possible
at the coast every morning through Tuesday.

Aviation Offshore flow has been suppressing the marine layer
resulting in generally favorable flying weather for north coast
terminals. Late tonight, a shallow marine layer will redevelop,
eventually becoming more widespread and persistent by Sunday
morning. Ifr conditions are therefore expected to impact both cec
and acv. Conditions should improve some in the afternoon on Sunday,
however coastal stratus will probably reform quickly. Interior sites
will remainVFR as warm dry weather holds, though brief stratus
may creep into uki from the south early Sunday morning.

Marine A gale warning for the outer waters and a small craft
advisory for the inner waters continues. Northerlies are expected to
diminish on Sunday, and then eventually drop below 15 kt by Monday.

Lighter winds and lower short period seas are expected to prevail
through at least mid next week.

Eka watches warnings advisories
Ca... None.

Northwest california coastal waters... Small craft advisory until
noon pdt Sunday for pzz450.

Gale warning until midnight pdt tonight for pzz470-475.

Small craft advisory until 6 pm pdt Sunday for pzz455.

It is not checked for accuracy either by anyone at L-36.com or by the source which is typically the US Government. See the NOAA web site for their disclaimer. 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.
