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 Warm and dry conditions will persist throughout the
interior for the remainder of the week. Coastal areas will see an
increase in clouds tonight and much of the day tomorrow, and for
the remainder of the week will likely see cloudy mornings followed
by mostly sunny afternoons.

Discussion After yet another hot day across the interior that
saw temperatures climb into the upper 90s to near 100 degrees,
some modest heat relief is in store for the region as upper level
high pressure is set to weaken over the next few days.

Temperatures tomorrow afternoon will fall back into the upper 80s
to mid 90s across interior valleys, and will more or less remain
in this range with minor fluctuations for the remainder of the
work week. No precipitation is expected for the foreseeable
future, as moisture will be in short supply, and skies will remain
generally sunny.

Meanwhile along the coast, widespread marine stratus clouds have
returned, and overcast skies can be expected in most places
through the night and into tomorrow morning, gradually expanding
into coastal river valleys and up to an elevation of around 2000
feet. Clouds will likely be slow to clear during the day Monday as
well, making for a mostly cloudy day aside from perhaps a few
hours in the afternoon. Through the remainder of the week, coastal
clouds will likely repeat a familiar pattern of developing in the
lowlands during the overnight periods and dissipate during the
late morning and afternoon, with typical cool temperatures in the
low to mid 60s.

Aviation Coastal stratus surged northward along the coast
today bringing ifr lifr ceilings to coastal airfields. Ceilings
are forecast to impact kacv by the early evening. These conditions
will continue along the coast tonight with improvement possible
by Monday afternoon as breezy north winds increase and break
ceilings.VFR will otherwise prevail across the interior. Kml

Marine Winds diminished slightly today with an afternoon ascat
passing confirming 15 to 25 kt northerlies across most of the the
waters. As this occurred, south winds developed along the
mendocino coast around 10 to 15 kt with gusts near 20 kt.

Northerlies will strengthen again on Monday with gale force wind
gusts possible across the outer waters by the afternoon. High
pressure offshore will maintain strong north winds through most of
next week with some fluctuations expected. Seas will remain steep
through a lot of next week. Wave models are also predicting a
moderate northwest swell to impact the waters over the next few
days but steep, wind driven waves will dominate the wave
environment. Small craft advisories remain in effect for the
waters through Monday, although the advisories are marginal
nearshore. The most "hazardous" areas will be near CAPE mendocino
and point saint george through the evening. Gales are possible
across the outer waters Monday afternoon but are looking to be low
end as of now. Either way strong winds and steep waves will
warrant some kind of advisory or potential warning for most of the
upcoming week. Kml&&

Fire weather Hot temperatures, low humidity and breezy onshore
winds have resulted in elevated fire weather conditions across
much of the area today... Particularly across eastern mendocino and
southern lake counties. Poor overnight humidity recoveries are
expected once again across the high elevations of this region,
although breezy winds are expected to weaken somewhat overnight.

Somewhat similar conditions can be expected Monday afternoon as
well, albeit with temperatures about 5 degrees cooler and wind
speeds about 5 mph slower than what was observed Sunday.

This pattern will remain relatively persistent through the
remainder of the work week, with temperatures fluctuating between
the upper 80s to mid 90s on most days, breezy onshore winds during
the afternoon, and only moderate humidity recoveries along
ridges.

Eka watches warnings advisories
Ca... None.

Northwest california coastal waters... Small craft advisory until 4 am pdt Tuesday for pzz450-455-470-
475.

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.
