Synopsis An isolated shower or thunderstorm will be possible
over the yolla bolly mountains this afternoon and evening.

Meanwhile, low clouds and patchy drizzle will likely redevelop
over humboldt bay during part of tonight. A more substantial
chance of showers is expected to develop over northwestern
california during Saturday evening. Thereafter, daily afternoon
shower and thunderstorm potential will exist over the interior
mountains Sunday through Friday.

Discussion Daytime heating is aiding in boundary layer
destabilization over the yolla bolly mountains this afternoon,
which is resulting in isolated shower development. That activity
will dissipate this evening with the loss of daytime heating. The
other short-term concern will be the redevelopment of stratus
over humboldt bay tonight. Model forecast soundings indicate that
a sufficiently deep saturated layer will be present for patchy
drizzle as well. However, WV imagery shows an upper low moving
south across wa and or, and that feature is forecast to usher in a
slightly drier and less stable boundary layer airmass during the
next 12 hours, which may aid in clearing stratus away from the
coast late tonight into Saturday morning.

The previously mentioned upper low is forecast to move south
across NRN ca during Saturday night. Multi-model guidance
indicates widespread light shower activity will be probable with
the low across the entire region Saturday evening and night.

Showers are then forecast to clear during Sunday as the upper low
moves south of the area. However, sufficient destabilization is
forecast to occur over the trinity and yolla bolly mountains
Sunday afternoon for showers and thunderstorms... That pattern is
forecast to repeat every afternoon from Monday through Friday.

Jmg

Aviation Marine stratus with ceilings near 1000 feet, as well
as patchy drizzle, are forecast to redevelop this evening in the
vicinity of humboldt bay. Farther north, model forecast soundings
show stratus briefly redeveloping at kcec during Friday evening.

However, a slightly drier and less stable airmass is forecast to
spread south across the region late tonight... Which may scatter
out low cloudiness at kcec, and perhaps even kacv. Over interior
mendocino county, a period of low clouds MVFR ceilings will be
possible over the russian river valley toward 06z Saturday.

Jmg

Marine A strong area of surface high pressure persists over the
nern pac Friday afternoon. That feature is forecast to shift
southward over the weekend, which will eventually lead to
weakening north winds and seas Sunday and Monday. In the meantime,
gale force northerlies will develop over the southern outer waters
tonight and will be accompanied by steep seas from 10 to 13 feet.

Elsewhere, solid small craft conditions are probable over the
northern outer and northern southern inner waters through Saturday
night.

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.
