Synopsis Dry weather will prevail across much of the region
through most of Friday. In addition, gusty north winds will occur
along the coast today and Thursday. Late in the week, an upper-
level disturbance will move across northern california and aid in
shower development over much of the interior.

Discussion An upper low was positioned over SRN ca Wednesday
afternoon, while a ridge was building over the nern pac. Dry
subsident conditions were occurring in between those two features
resulting in pleasant weather over nwrn ca. At the surface, a
strong area of high pressure was located offshore from the west
coast. The high was aiding in strong northwest winds gusting from
20 to 30 mph along the coast... Those winds are forecast to persist
through Thursday afternoon.

Otherwise, an upper disturbance is forecast to dig south from
wa or Friday through Sunday. Shower chances will subsequently
increase... Locally over the trinity and yolla bolly mountains on
Friday, and then over most of the interior Saturday through
Monday. In addition, model guidance shows sufficient
destabilization will occur during Friday, Saturday, and Sunday
afternoons for isolated thunderstorm development over the
mountains.

Aviation Pesky low clouds have remained around humboldt bay
this afternoon however a few breaks have begun to develop. These
breaks should fill in later tonight as the marine layer
strengthens as high pressure builds in aloft. Gusty northerly
winds are also present along the coast this afternoon but will
decouple this evening. Across the interior, mostly sunny skies and
light to moderate winds will continue through the remainder of
the TAF cycle. Tonight, as warming aloft continues low clouds will
blossom along the coast primarily affecting acv and cec. Expect
MVFR to ifr ceilings and reduced visibilities to develop late this
evening and persist through at least much of the morning
tomorrow. Gusty northerly winds will also ramp up again late
tomorrow morning and afternoon along the coast. Wci

Marine An inland thermal trough will remain across the area
through the end of the week keeping a tight pressure gradient over
the area. Therefore, gusty gale to near gale force northerly
winds will continue through the end of the week. A few locations
across the inner waters may see gale force gusts especially around
pt st george and CAPE mendocino however due to limited spatial
extent will maintain the small craft advisories across the inner
waters. NW swell will continue to decay however short period seas
will begin to steepen due to these strong northerly winds. Low
pressure will begin to approach the coast Friday into Saturday
which will help to break up the pressure gradient leading to
weakening winds Saturday and especially on Sunday. Seas will
remain elevated through Sunday morning but gradually decline into
early next week. Wci

Eka watches warnings advisories
Ca... None.

Northwest california coastal waters... Small craft advisory until
3 am pdt Friday for pzz450-455.

Gale warning from 6 pm this evening to midnight pdt Thursday
night for pzz470.

Hazardous seas warning until 6 pm pdt this evening for pzz470.

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.
