Synopsis The very dry late fall continues with mild
afternoons and chilly nights. Areas of smoke and haze will
continue to dim the otherwise sunny skies today, but may drift
east of our region for Thursday as marine stratus threatens
coastal areas. Dry weather will persist through the weekend
while rain chances improve toward thanksgiving.

Discussion High cloud cover associated with a weak mid-level
disturbance will continue to pass across northern california
but should be less dense than what was observed yesterday (tues).

However some smoke will continue to plague the area both from the
large fires near chico and now a new smaller fire near hoopa. As
the tail- end of a weak cold front clips southern oregon on
Wednesday, the low and mid- level flow will become more westerly
which will should help to gradually clear the smoke from west to
east. Chilly early mornings and resulting frost continues to be an
issue where late fall agriculture is still sensitive. Frost
advisories remain in effect this morning for western humboldt
county but this should be the last morning before slight warming
and higher dewpoints should prevent near freezing temperatures.

Model guidance, particularly the NAM and hi- res arw are pointing
toward a threat of more stratus and fog along the coast Wednesday
night and Thursday morning, as well as Thursday night and Friday
morning. The overall airmass across our region will continue to
gradually moisten, but still will remain quite dry as an upper-
level ridge rebuilds overhead for the end of the week and the
weekend. Weak offshore flow looks to return early Thursday and
Friday morning as well with dry and sunny weather prevailing once
again. Heading into next week, models depicting a wetter pattern
shaping up right around thanksgiving... However we have seen the
models show wet patterns a week out that did not transpire so
confidence remains fairly low. Nonetheless did bring pops up
to near 40% for this period. Aad jt

Aviation Areas of smoke and haze will persist across the region
during the next 24 hours resulting in modest reductions to
visibility. However, model guidance shows light to moderate north-
northwest winds developing this afternoon, which may aid in clearing
smoke haze in the vicinity of kcec. The north-northwest winds may
also usher in marine stratus near kcec. Early morning observations
at kcec showing ovc at 3500 feet already hint at that possibility.

However, model guidance is somewhat ambiguous regarding stratus
evolution as the day progresses. Thus, forecast uncertainty is
elevated.

Marine Strengthening high pressure over the nern pac will aid in
the development of northerly winds from 10 to 20 kt this afternoon
through Thursday night. Wind waves will build as a result, and will
contribute toward combined seas from 10 to 12 feet as a west-
northwest swell near 9 feet at 15 seconds spreads across the coastal
waters during Thursday. Thus, a small craft advisory mainly driven
by hazardous seas has been issued, valid Thursday morning through
Thursday night.

North winds are forecast to weaken Friday night into the weekend as
low pressure develops offshore. Otherwise, another mid to long
period west-northwest swell will arrive Saturday and persist into
early next week.

Eka watches warnings advisories
Ca... Frost advisory until 9 am pst this morning for caz103-104.

Northwest california coastal waters... Frost advisory until 9 am pst this morning for pzz410.

Small craft advisory from 4 am Thursday to 4 am pst Friday for
pzz470-475.

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.
