Synopsis Temperatures will cool slightly in some areas today
as an upper level trough impacts the area. Cooler temperatures
will continue through the week with additional cooling expected
for the weekend. The coast will continue to see night and morning
clouds with some afternoon clearing. Otherwise, smoke will
persist across most of the inland areas through the rest of the
week.

Discussion An upper level trough is settling over eastern or
and idaho and extending into northern ca. This is bringing some
subtle changes to the surface. The northeast flow on the north
side of this trough is bringing some smoke from the oregon fires
to the area. At the coast the inversion is keeping most of the
smoke aloft, although late this morning and early afternoon it is
possible some will make it to the surface. In the interior valleys
smoke is likely thick near the fires this morning. This afternoon
with the trough overhead winds aloft become very light.

Temperatures aloft will remain consistent in most areas today and
Wednesday with highs in the low to mid 90s. Farther south as far
inland as ukiah will see some additional marine influence. This
will keep ukiah around 90 for the next several days. Some stratus
may make it up to ukiah each night.

Thursday night another trough moving through from the northwest
is expected to bring cooler temperatures on Friday. This will
likely bring widespread drizzle and fog to the coastal areas. The
models are in decent agreement on this gradually deepening through
the weekend with inland temperatures slightly below normal. The
gfs is early next week models are showing high pressure building
back into the region with temperatures starting to warm back up to
normal. Current model runs are showing this trough to be dry. Mkk

Aviation Stratus continues across the entire coastal waters area
as well as adjacent land areas and river valleys. The marine layer
is running about 1500 feet deep based on the acv profiler as well as
satellite imagery. Model guidance indicates that low clouds will
hang in through the day along the redwood coast, although ceilings
will rise a bit and visibilities, which have been varying between
MVFR and occasional ifr, will increase as well. Lamp guidance shows
the best chance of low clouds scattering out briefly in the
afternoon will be at kcec. However, winds are forecast to continue
light onshore along the coast, and low ceilings are likely to
persist.

At kuki, skies are presently clear. However, low clouds are creeping
n in the russian river valley, and high resolution guidance
indicates possible ceilings for a few hours early this morning.

Otherwise, nearby smoke may continue to generate high ceilings. Low-
level winds are expected to be light and mostly westerly. This
should keep visibilities from being reduced too much, but
uncertainty is high. Sec

Marine Winds and seas have dropped below advisory criteria in the
outer waters. Expect conditions to continue improving through the
day as winds back to southerly. Northerlies will return late in the
week with speeds increasing to advisory levels at least in the outer
waters by Thursday night. A small wnw swell at around 11 seconds
will continue until late in the week. Sec

Fire weather The marine layer is slowly deepening in mendocino
county and this will bring cooler temperatures and higher rh to
much of the area. Farther north conditions will be fairly similar
to yesterday. This pattern will continue into Wednesday. Thursday
into the weekend and early next week additional cooling is
expected. The coolest days currently look to be Sunday and Monday
with highs in most areas only in the 80s. Afternoon rh and
overnight recoveries will improve some as well. No thunderstorms
are expected at this point. Mkk

Eka watches warnings advisories
Ca... None.

Northwest california coastal waters... None.

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.
