Synopsis Temperatures will gradually cool through the weekend,
followed by a warming trend during the second half of next week.

Otherwise, dry weather will prevail during the next seven days.

Discussion Northwest flow aloft is forecast to evolve into
troughing over the nern pac Sunday through early next week. That
evolution will aid in ushering in a cooler airmass across nwrn ca,
with high temperatures across the interior cooling around 10
degrees compared to values observed on Friday. Otherwise, model
guidance shows patchy stratus potentially becoming more widespread
Sunday-Tuesday. In addition, marine layer moisture may deepen
sufficiently for coastal drizzle Monday and Tuesday mornings.

Beyond Tuesday... Dry weather will continue through mid to late
next week. In addition, warming deep-layer temperature profiles
will aid in the redevelopment of hot temperatures across interior
valleys.

Aviation One more day of favorable flying weather along the
northcoast and mendocino coast as the marine clouds and fog are
not expected to hamper conditions again through the next taf
cycle. By Sunday however the marine influence should become more
evident with periods of MVFR or brief periods of ifr are likely at
both cec and acv. Interior sites should remain generallyVFR as
warm dry weather continues.

Marine A gale warning for the outer waters and a small craft
advisory for the inner waters continue. Northerlies are expected
to gradually diminish on Sunday. The northerlies will fall to 5-10
kts by Monday presenting a very tranquil wind field through the
remainder of the week. Short period seas around 12 to 14 ft will
persist across the outer waters through Sunday but will also
subside early in the week with a rather small wnw swell lingering
through next week.

Eka watches warnings advisories
Ca... None.

Northwest california coastal waters... Small craft advisory until

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.
