Oakdale, CA

Version 3.4
What's New / NOTES
5/20/2018 -- NOAA is having problems with the data feed that I use to draw the graphs. They are aware of the issue and working to resolve it. Sometimes changing the location by about a mile will give a correct graph. 3/3/2018 - There is a new GOES Satellite for the east coast that required rewriting that part of the code. Please report any issues.

Synopsis for the central california coast and bays including the Monterey bay..Greater farallones...and cordell bank national marine sanctuaries... Moderate to strong northwesterly winds will persist over the coastal waters through Monday in response to a tight north to south pressure gradient along the coast. These winds will result in steep wind waves as well and produce hazardous conditions for small crafts. A long period southerly swell will increase and mix with northwesterly swell by Monday morning, gradually increasing through much of the week.

233 pm pdt Sun may 20 2018

Synopsis
Afternoon and evening thunderstorms possible over higher terrain
much of this week. Seasonal temperatures continue across the
region.

Discussion
Getting some showers and isolated thunderstorms over the northern
mountains and along the northern coastal range this afternoon. The
activity is expected to continue into the evening before
tapering.

A low pressure area will move southward overnight through the
central part of california. This may trigger some showers over the
western slopes later at night as it moves towards southern
california. Unstable air is still forecast for the region with
most of the activity continuing to remain over the mountains and
foothills. Westerly flow may bring a few showers or isolated
thunderstorms into the valley in the evening hours on Monday and
mainly over the eastern end of the valley from around chico
southward.

On Tuesday the low will move northeast into the great basin with
easterly flow continuing to bring moisture westward back over
northern california. Continued showers and thunderstorms for the
mountains and foothills is expected. This might also be the best
chance for activity to move over the valley... Mainly north of
i-80.

The low over the great basin begins to lift northeast on
Wednesday and winds aloft will shift southerly over the region.

Less activity is expected compared to the prior two days. Most of
the activity should stay over the mountains but the north end of
the valley may continue to be under the threat of thunderstorms.

Decent flow will continue through the delta the next few days and
temperatures for most locations with remain near seasonal normals
with the exception of the north end of the valley which will warm
to around 90 degrees the next couple of days.

.Extended discussion (Thursday through Sunday)
closed upper low off the california coast Thu into fri, tracks ne
through interior norcal sat. This will continue a threat of
showers and afternoon evening thunderstorms over the foothills and
mountains, and possibly in the northern sacramento valley. By
Sunday, low is progged into oregon with a decreased threat of deep
moist convection over the cwa. High temperatures forecast to be
near to slightly above normal through the extended period with 80s
in the central valley, and mostly 60s to 70s for the mountains
and foothills.

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.
