Synopsis The weather will return to a more typical summer
pattern of mostly dry conditions with warm inland temperatures
returning and persisting through the weekend. Marine stratus will
continue along the coast during the overnight and early morning
hours through rest of this week.

Discussion Low clouds continue to cover much of the coastal
waters and adjacent land areas. However, with increased N flow,
large clear regions have formed downwind from SW oregon and cape
mendocino. The marine layer remains fairly deep (at least 2000
feet deep). As a result, there are minimal visibility reductions,
but the clouds themselves are well inland into the higher
elevations. The marine layer is forecast to become more shallow
today with partial clearing later in the day along the coast.

Nighttime and morning coastal clouds will continue over the next
few days, but improvement should be noted by each afternoon.

Inland temperatures will rise to about 10 degrees above normal today
as an upper ridge builds back over the area, and this should
continue through the weekend with a slight cool down early next
week. Present indications are that little in the way of offshore
flow will develop, which will keep coastal areas seasonable. The
weather will be mostly dry. Sec

Aviation Expect something close to persistence for the aviation
forecast with ifr ceilings lifting into the afternoon, with some
coastal areas seeing some blue skies, and returning again tonight.

North winds will not only bring breezy conditions to coastal
airfields but should also help scatter out coastal cloud cover
especially along del norte county and northern mendocino county.VFR
will prevail across the interior. Kml

Marine Fresh to moderate winds and steep seas will persist
through the next several days as high pressure stationed offshore
maintains a tight gradient. The existing small craft advisories
remain in effect. Winds across the northern waters could diminish
subtly Thursday night into Friday. However, they will increase again
over the weekend with more numerous gale force wind gusts possible
across the outer waters. Thus, our existing advisories may need to be
extended or upgraded later this week. Kml

small craft advisory until 3 am Friday for pzz450-455-470-475.

It is not checked for accuracy either by anyone at L-36.com or by the source which is typically the US Government. See the NOAA web site for their disclaimer. 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.
