Synopsis Dry weather is expected across most of northwest
california through the middle of next week. High temperatures will
generally be in the 80s to low 90s across the interior, with
some warming over the weekend. In addition, abundant sunshine
will occur across inland areas this week, while periods of marine
stratus continue for most of the coast.

Discussion Nearly zonal flow aloft will bring a fairly
persistent pattern across the area for the next several days,
although a few weak shortwaves will bring a some subtle changes.

Stratus has formed across the humboldt and del norte coasts north
of CAPE mendocino and spread well up many of the river valleys.

The marine layer is fairly deep, but the inversion is not
particularly sharp so there are some breaks in it. This should
allow clouds to clear back to the coast this afternoon.

Temperatures inland will generally be similar to yesterday.

Northerly winds of 10 to 20 mph are expected north of cape
mendocino on the coast.

Tonight a fairly quick return of stratus on the humboldt coast is
likely, although offshore flow will may keep it out of del norte
county. The offshore flow is weaker in mendocino county so some
stratus is likely there as well. Friday temperatures will be
similar to Thursday across the area. Stratus is expected to clear
back to the coast Friday afternoon north of CAPE mendocino,
although confidence is lower south of CAPE mendocino.

For the weekend high pressure builds slightly over the area and
temperatures inland are expected to warm by a few degrees.

Offshore flow weakens and stratus will likely become more
prevalent at the coast. Next week there are some indications,
particularly in the operational gfs, that we will see a trough
again with inland temperatures dropping back to the upper 80s to
low 90s. The ECMWF and the GFS ensembles however are not showing
the trough as strong. Either way there are not expected to be
significant changes in the pattern. Mkk

Aviation Generally lifr conditions have been prevailing across
coastal areas however some sporadic clearing and ceiling height
changes have been occurring around humboldt bay and acv. Expect
low ceilings and visibilities to prevail along the coast through
the early morning before conditions begin to improve by late
morning. It seems likely thatVFR conditions will be possible (for
at least a few hours) at cec and acv by early afternoon similar
to what happened yesterday. Areas around humboldt bay may not
completely clear up but still expect at least broken ceilings to
develop in the afternoon. Coastal locations will also experience
strong northerly winds for much of the afternoon today as an
offshore pressure gradient develops. Tonight, expect ifr ceilings
and visibilities to redevelop once again however formation may be
a bit delayed across del norte county until the boundary layer
decouples late this evening. Interior locations will remainVFR.

Marine Offshore pressure gradient has begun to tighten this
morning, which will lead to a rapid increase in northerly winds by
the afternoon. Winds will be strongest across the outer waters,
near pt. St. George, and CAPE mendocino where sustained winds of
25-30 kts with gusts to 40 kts will be possible this afternoon
through Saturday morning. Elsewhere, sustained winds of 15-20 kts
can be expected. These strong northerly winds will lead to
steepening short period seas peaking Friday into Saturday morning.

Sea heights of 9-12 feet around 9 seconds will be possible across
the outer waters with 6-8 feet around 6 seconds across the inner
waters. Decided to issue a hazardous seas warning for the southern
outer waters during this time to account for the very steep seas.

Conditions will begin to improve late in the weekend through
early next week. Wci
