Synopsis
Cooler, but still remaining close to average into the weekend.

Discussion
Short wave trof will be moving across our NRN mtn zones this
afternoon with instability forecast over the trinity alps siskiyous,
just N of our CWA where isolated convection is expected. Less
instability forecast on Tue even though weak troffing persists over
the region. This is the result of today's short wave providing
stronger dynamics than tue's. CAPE and modified total totals are
much lower on Tue than today.

Break down of the ridge over the W coast allows for a cooler air
mass over our cwa. Onshore gradients have advected some marine
stratus inland, into the coastal valleys with some patchy stratus
into the SRN sac vly. Ft ord and the koak RAOB show marine layer
about 3 kft and 2.5 kft respectively, which is sufficiently deep for
at least some stratus to make it inland given onshore gradients and
onshore momentum. The NAM bufkit profiles suggest slight deepening
of the marine layer Tue morning, but the onshore gradients should be
weaker as the aforementioned short wave will be farther inland.

Although the delta breeze will continue it should be weakening with
time into tue. So only patchy stratus inland is expected at this
time for Tue morning.

Near normal temps expected next couple of days with a warm up to 2
to 7 degrees above normal for the mid and latter half of the week.

Lav guidance trending lower than our forecast maxes in some areas
and may have to lower MAX temps in a morning update. Jhm
.Extended discussion (Friday through Monday)
warm weather should continue into Friday as high pressure over
the eastern pacific nudges into northern california. A series of
weak upper troughs then begins to move through the region next
weekend, bringing another cooling trend along with increased
onshore flow. The GFS is a bit stronger with the series of troughs
than the ecmwf, but neither solution would be particularly
impactful for our area. Dang

Aviation
Vfr conditions the next 24 hours. South to west winds 5 to 15 kt
will continue across valley TAF sites. SW gusts up to 30 kt near
the delta. Dang

Sto watches warnings advisories 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.
