Synopsis Light rain will be possible this morning into
Wednesday evening over del norte and northern humboldt county.

Otherwise, mild and dry conditions are expected to prevail across
the region through the weekend.

Discussion An upper ridge was located over the nern pac early
Wednesday morning. Several weak upper impulses were embedded
within the apex of the ridge. These features are forecast to
spread across western or during the day, and as that takes place,
a minor surface boundary will sag south toward far nwrn ca. Model
forecast soundings show that nearly saturated thermodynamic
profiles from the surface to 750 mb will materialize this morning
and afternoon in the vicinity of coastal northern humboldt and
del norte counties. Available model guidance indicates this
moistening will be sufficient for very light precipitation through
Wednesday evening.

The previously mentioned ridge will essentially be a permanent
fixture over the nern pac and west coast through at least
Saturday. Next Monday... There is multi-model agreement in the
progression of a shortwave trough moving from swrn canada to the
great plains. In the wake of that trough, a strong area of
surface high pressure is forecast to build southward across the
intermountain west, which will subsequently yield a tight offshore
oriented pressure gradient. This will lead to strengthening north
and east winds across the region, as well as the influx of a very
dry continental airmass. Otherwise, mild and pleasant conditions
are probable Thursday through early to mid-next-week.

Jmg

Aviation A weak front is pushing across the ridge of high
pressure and will bring an increase in lower clouds to the north
coast later this morning and this afternoon. MVFR conditions both
in cig and vsby are expected this afternoon as the front pushes up
against the coast with some light precip likely at cec and acv.

The front will remain nearly stationary through early evening
before finally dissipating and moving east late. Then a return to
drier...VFR type conditions are expected on Thursday. Interior
areas should generally be immune to the lower CIGS and vsbys today
but sunrise ground fog is not out of the questions later this
morning and tomorrow.

Marine Moderate to fresh northerlies will prevail across the
waters through the end of the week, with light precipitation
possible later today as a weak front moves to the east. As is
often the case in northerly flow regimes, the strongest winds are
expected to occur from CAPE mendocino southwards, where winds of
between 15 and 25 kt are expected to generate some moderately
steep seas. Otherwise, ocean conditions will generally remain
dominated by a series of long period westerly swells, the first of
which will arrive Wednesday morning. While small in comparison to
some of the larger swells we've seen this season, these swells
will likely bring significant wave heights to near and even
slightly above 10 feet, prompting the issuance of widespread small
craft advisories.

Eka watches warnings advisories
Ca... None.

Northwest california coastal waters... Small craft advisory from 8
am this morning to 3 am pst Thursday for pzz450-470.

Small craft advisory from 8 am this morning to 9 pm pst Thursday
for pzz455.

Small craft advisory from 8 am this morning to 3 pm pst Friday
for pzz475.

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.
