Synopsis Hot and dry conditions through next week for interior
locations, as a strong ridge of high pressure builds over the west
coast and persists into next week. Along the coast, expect seasonal
temperatures with fog and low clouds during the overnight hours.

Discussion The biggest weather story for the next 7 days will be a
strengthening ridge of high pressure building over the west coast.

Hot weather will be in store for the interior through next week,
with highs around 100 to 105 f in weaverville area, and highs near
the century mark in ukiah. This will be about 5 to 10 degrees above
normal. So far this month, temperatures in the area have been
running above normal for NW california. Thus, the warmer than normal
trend will continue into early august.

Along with hot weather, dry conditions will be in store. There will
be no precipitation potential through the weekend into next week.

There maybe a few weak upper level disturbances passing through the
area, if there is weakness in the upper level ridging. This may
bring slight increase in sky cover. Don't expect the weather pattern
to change much in this summery pattern. Hot and dry inland, marine
stratus along the coast. Changes to the previous forecast package is
minor.

Marine The pressure gradient between the inland thermal trough
and the E pacific high pressure will continue to produce small craft
advisory level winds over the outer waters with marginal advisory
level seas across the N inner waters. Have extended the N inner
small craft advisory into Sunday night. Occasional wind gusts to
gale force are expected in the outer waters from today into the
weekend. Models continue to indicate a long period S swell building
into the area by early next week. Sec

Aviation Marine stratus and some patchy fog along the redwood
coast continues with a clear hole downwind of CAPE mendocino
including the SW humboldt and NW mendocino county coasts. Stratus
extends well inland up the coastal river valleys. Latest acv
profiler shows that the marine layer has deepened to at least 2000
feet. As a result, although ceiling heights are forecast to rise
through the day, redwood coast sites may remain bkn through the day.

The best chances for breaks in the cloud cover will be at kcec. In
addition... Any low-level flow more out of the N at kacv may result
in some partial clearing due to downsloping from terrain.VFR
conditions are expected to continue at kuki. Sec

Eka watches warnings advisories
Ca... None.

Northwest california coastal waters... Small craft advisory until midnight pdt Sunday night for pzz450-
470-475.

Small craft advisory until 5 pm pdt this afternoon for pzz455.

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.
