Synopsis Most areas will be warm and dry today, but isolated
showers and thunderstorms will be possible across trinity and
mendocino counties this afternoon and evening. There will be
additional chances for showers and isolated thunderstorms for
these areas through the end of the week. Otherwise, a gradual
warming trend is expected through the end of the week.

Discussion A broad upper-level trough over the great basin and
high pressure over the eastern pacific leaves the region in a
northerly flow aloft regime. A weak, upper-level shortwave
embedded in the northerly flow will move southward today.

Lingering moisture and instability associated with the disturbance
will lead to some isolated showers and thunderstorms across
northern and eastern trinity and mendocino counties this afternoon
and evening. Elsewhere, mostly dry and warm conditions are
expected. Cloudy conditions are expected to persist along the
coast today, with mostly sunny skies forecast across most of the
interior. Patchy fog and drizzle will be possible again tonight
along the coast.

The upper-level trough over the great basin will gradually shift
eastward through the week. As a result, north to northwesterly
flow aloft will persist across the region. Several embedded
impulses are forecast to move southward in the northerly flow
through the end of the week. These impulses and lingering moisture
will lead to possible isolated showers and thunderstorms in the
afternoons and evenings across interior mountains through the
remainder of the week. Wednesday afternoon and evening appear to
have the greatest chances at this time. Mostly dry conditions are
expected to prevail elsewhere. Otherwise, temperatures will
gradually warm across the forecast area this week.

Aviation Widespread ifr to lifr conditions have developed along
the humboldt and del norte coasts early Monday morning, affecting
both cec and acv. In addition, some localized drizzle is affecting
acv, resulting in somewhat reduced visibilities as well. This is
expected to continue through at least mid-morning, but should
improve slightly during the afternoon. However, at least broken low
clouds are expected to persist much of the day, especially in the
vicinity of acv, and aviation interests should not expect ceilings
to improve to better than MVFR conditions for any significant length
of time. Ceilings are expected to drop to ifr levels again
overnight.VFR conditions have prevailed at uki, but some ifr low
clouds may work their way into the valley near or slightly before
daybreak. These clouds are expected to dissipate before the
afternoon. Brc

Marine Northerly winds have settled slightly across the
waters, allowing for seas to gradually diminish as well. However,
while a downward trend is evident, seas do remain somewhat
elevated throughout the waters early this morning, with buoy
observations indicating seas of between 6 and 7 feet at 8 to 9
seconds. Wave heights will continue to slowly subside through the
day within a regime of persistent 10 to 15 kt northerly winds,
although some localized winds to around 20 to 25 kt immediately
south of CAPE mendocino will likely maintain some slightly larger
and steeper seas over a limited geographic area.

Overnight and Tuesday morning, northerlies will begin a gradual
upward climb that will continue through the day and overnight
Tuesday. The first region that will see these increasing winds will
be near and south of CAPE mendocino, but by Tuesday night widespread
sustained winds of 20 to 25 kt can be expected in all but the
northern inner waters, which will remain slightly sheltered from
these stronger gusts. As a result, seas will gradually build and
become steep over the course of the day Tuesday, eventually reaching
around 8 to 11 feet by overnight. These strong northerlies will more
or less persist through the end of the week, with little relief from
these choppy conditions in sight. 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.
