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 Numerous showers with embedded thunderstorms will
occur across the region through this afternoon. Showers will then
dissipate tonight, with drier conditions developing Sunday through
the middle of next week. Much warmer temperatures are likely
across the interior Monday and Tuesday, while a cooler marine
airmass persists along the immediate coast.

Discussion An upper-level low was approaching the cntrl ca
coast Friday morning. Lobes of stronger ascent were rotating
around the northern and eastern portions of the low, and were
serving to focus concentrated zones of showers embedded
thunderstorms. Locally, the bulk of the activity was occurring
over mendocino county and areas offshore south of CAPE mendocino
early Friday morning. However, short term model guidance indicates
the remainder of nwrn ca will fill in with showers by mid Friday
morning.

As the day progresses, model output shows shower activity becoming
concentrated sw-ne within a midlevel deformation zone, which will
begin to shift ewd away from the coast during the evening. This
will be followed by a dry subsident airmass that is forecast to
spread across the region during Saturday. Shower development will
subsequently shut down, leading to more tranquil conditions by
Sunday.

Going into early next week... Abundant interior sunshine, combined
with nne boundary layer winds, will aid in warm daytime highs in
the upper 80s to low 90s from roughly weaverville SW to ukiah
Monday and Tuesday. Thereafter, a cooler airmass is forecast to
spread southward across the region during midweek.

Otherwise, most of the area will remain dry next week, with the
exception of the trinity horn, where a stray afternoon shower
will be possible Tuesday through Thursday.

Aviation Weather at acv and cec continue to be dominated by
multiple layers of coastal stratus early this morning. Lifr
conditions have persisted at cec, while ceilings and visibilities
have fluctuated from lifr to MVFR at acv. These variable low
ceilings will likely persist through the morning, with little
indication that ceilings will improve, and little hope of any
consistentVFR conditions at any point today. By mid to late
morning, numerous showers will likely begin impacting coastal
terminals, and this will continue through the late afternoon or
perhaps even early evening. Occasional lightning strikes will be
possible at both cec and acv during this time frame. Showers will
likely cease by late evening, but low stratus will likely continue
through the night.

At uki, showers have already begun impacting the terminal, and
will likely continue to do so periodically through the day and
possibly into the evening. Like coastal areas, occasional
lightning strikes will be possible. Prevailing MVFR ceilings can
be expected, with both occasional breaks and dips into ifr
categories. Brc

Marine Northerly winds are expected to increase this
afternoon, particularly across offshore waters and near prominent
points and capes like point saint george and CAPE mendocino. Gusts
to 25 kt will be possible in these typical trouble spots this
afternoon and evening. Meanwhile, seas will build and become a bit
steeper, with a mix of northerly wind waves and northwest swell
and significant wave heights between 6 and 9 feet overall.

Winds will weaken slightly early Saturday, but mostly north of
cape mendocino, allowing steeper seas to settle for a brief
period. However, winds and steeper seas will continue south of the
cape, and on Saturday night northerly winds will begin to
increase again across all waters. These winds will continue to
increase through Sunday, and by Sunday night gale force winds will
be a possibility. These strong northerly winds are expected to
continue through the remainder of the week as well, so mariners
should prepare for an extended period of large, steep, and
hazardous seas throughout the local waters. Brc

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.
