Light to moderate northwest winds will persist across the coastal waters through mid-week as high pressure sits over the eastern pacific and low pressure develops over central california. Locally gusty coastal jets are forecast south of point arena, pigeon point, and point sur that will create hazardous seas conditions for smaller vessels. Breezy afternoon and evening winds are also forecast over the san francisco bay as well as over the Monterey bay. Mixed seas will continue with shorter period northwest waves at around 8 to 10 seconds, a light longer period west swell, and a light southerly swell.

Synopsis
Strengthening high pressure will result in dry weather with above
average temperatures into next week.

Discussion
Satellite imagery shows the upper trough approaching the pacnw
with a few weak short-waves out ahead of it bringing some high
clouds to norcal. Little if any stratus is noted along the coast
and profiler data indicate the marine layer has been mixed out and
is very shallow (less than 500 ft). Current temperatures are
running within a couple of degrees of readings 24 hours ago and
generally range from the 40s in the mountain valleys, to the upper
50s and 60s across the central valley.

Despite the trough passage to our north today, temperatures will
begin to increase across the region as onshore flow weakens. High
pressure will strengthen Thursday into the weekend resulting in
above average temperatures with most valley locales expected to
see highs around, or slightly above, the century mark.

Extended discussion (Sunday through Wednesday)
Upper high extends NW from the desert SW over interior norcal as
epac high extends inland. This will result in continued above
normal temperatures Sunday into next Wednesday. Triple digit heat
expected in the northern sacramento valley with upper 90s
elsewhere in the central valley.

These are not intended to be fact, they are my opinions. 4) Small programs that generate result presented on a web page. Like any computer program, these may and in some cases do have errors. Almost all of these also make simplifying assumptions so they are not totally accurate even if there are no errors. Please verify all results. 5) Weather information is from numerious of sources and is presented automatically. 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.
