Synopsis A broad upper level trough will bring near to below
normal high temperatures through the rest of the work week. A
gradual warm up is expected for the weekend into early next week.

Coastal areas will continue to see night and morning clouds with
afternoon sunshine.

Discussion Inland temperatures will fall another 5 to 10 degrees
today as a broad upper trough slides over the pacific northwest.

This trough axis will lie across northern california today and
tomorrow which will prolong near to slightly below normal
temperatures. Coastal areas will remain more seasonal with stratus
being the feature of interest over the next few days. Stronger north
winds offshore has helped to keep the redwood coast pretty much from
from low clouds with the exception of low clouds over the eel river
delta and other valleys. The coastal eddy south of CAPE mendocino is
forecast to remain in place and reinforce stratus along the
mendocino coast. Areas just inland will likely see some blue skies
in the afternoon but stratus should remain on the coast through the
day. Coastal stratus should surge up to the redwood coast tonight as
southerly winds develop nearshore.

Looking into the weekend, high pressure will build in behind the
upper trough as it tracks to the east. This will bring another
warming trend this weekend with inland temperatures approaching the
mid 90s late this weekend into early next week. Little changes were
made as far as storms in the forecast for the mountainous interior.

Spc outlined the eastern portions of the forecast area for thunder
on Saturday, however, we remain skeptical as the ridge axis will
move over the western united states. Chances for storms look better
into early next week as the ridge tracks eastward and a shortwave
generates southeasterly flow. Kml

Aviation Strong N winds over the coastal waters have led to
mostly low clouds tonight over the windward side of some of the
coastal hills as well as up the inland river valleys, particularly
the eel. As of this writing, kcec and kacv are reporting clear skies
and no significant visibility reduction. As winds decrease late
today and tonight, low cloudiness will likely re-form over the
coastal waters and advect inland. Speaking of winds, gusts of 20 to
25 knots will continue thru the day at kcec. These winds will begin
to diminish later this evening. Winds at kacv will be lighter, but a
few gusts over 15 knots are possible this afternoon.

Low ceilings cover kuki this morning, although ceilings have come up
a few hundred feet during the past few hours. Expect these clouds to
lift and thin this morning. Due to the increasing ceilings and t td
spread of 4 degrees, not expecting much in the way of reduced
visibilities. Winds will be generally light. Sec

Marine Winds in the coastal waters peaked overnight and will
slowly diminish through the day. Still, gales will continue over the
s outer waters thru mid-morning and thru the afternoon over the n
outer waters. The gale warning for the N inner waters has expired,
but have issued a hazardous seas warning thru mid-morning to account
for elevated seas. Lighter winds will return for the weekend. N
winds will increase once again by Monday of next week. Sec

Eka watches warnings advisories
Ca... None.

Northwest california coastal waters... Small craft advisory until 6 pm pdt this evening for pzz450-455.

Hazardous seas warning until 9 am pdt this morning for pzz450.

Gale warning until 6 pm pdt this evening for pzz470.

Gale warning until noon pdt today for pzz475.

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.
