Marine Weather and Tides
East 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... Generally light to moderate winds across the coastal waters today as we feel the effects of a southerly surge. Gusty northerly winds can be expected today across the northern waters and locally along parts of the inner coastal waters and in the san francisco bays. Winds will increase tomorrow as an upper trough moves through to the north. Gusty winds will generate steep wind waves creating hazardous conditions, especially for smaller vessels.

Synopsis
Cooler in the delta area today, while inland areas remain hot and
dry. Temperatures return to near normal beginning Monday and
through the rest of the week.

Discussion
The northerly pressure gradients, over 10 mbs at press time, are
forecast to decrease rapidly into the 3-4 mbs range by 18z today.

This will occur as low pressure over the rockys moves into the
central plains by the end of the day and high pressure moves over
norcal. This will bring an end to the desiccating nly barrier jet
winds that staudenmaier (1994) and mathews & juskie (2005) have
documented in wrh ta-lites as having an impact on wind advisories
and red flag warning considerations. These winds helped the rapid
spread of the stoll, pawnee, land and bascom wildfires in our cwa
on sat. The lane and pawnee wildfires were showing some "hot"
satellite signatures through the night.

Already seeing signs of a healthy onshore gradient developing from
sfo-sac at 2.5 mbs at 09z, and a return of the delta breeze to suu
of 14 kts. Satellite shows a return of stratus to the sfo bay area
with the ft ord profiler showing the marine layer deepening to
nearly 2 kft just past midnight. These are indications of some much
cooler air spreading into the SRN sac vly today which should keep
max temps below triple digits. Thus, have removed zone 17 from the
heat advisory.

Still a hot day away from the delta as the ridge axis moves over the
region today, although areas away from the delta will finally see
some cooler air spreading over their areas tonight and mon. Expect
some stratus to move towards suu Mon and Tue mornings. Will have
to watch for how much the marine layer deepens Mon Tue mornings
for a potential stratus intrusion into the SRN sac vly.

Seasonable wx returns to the CWA Mon as another pac NW trof provides
onshore flow and some cooling. This will be followed by slight
warming on Tue as high pressure from the desert SW builds nwd. Then
a slight cooling trend on Wed as another trof moves across the pac
nw. Jhm
.Extended discussion (Thursday through Sunday)
broad upper troughing moves through Thursday then interior norcal
sandwiched between epac upper ridge and downstream trough. Ridge
remains offshore through the weekend limiting amount of interior
heating. Attm, high temperatures expected to be above normal
through the extended, but not excessively hot with 90s expected
in the central valley and 70s to low 90s for the mountains and
foothills. Dry weather continues with breezy northerly wind Friday
into the weekend.
