Synopsis
Temperatures will continue to warm over the next few days, with warm
temperatures likely across the interior, and seasonably warm
readings near the coast. Some coastal river valley stratus will
develop during the late night early morning hours through the
weekend. Isolated thunderstorms may develop across the interior
through much of the upcoming week, especially for trinity county.

Discussion
Short term
(tonight through Saturday night)
clouds have been very persist all day over the waters, near the
coast, and across most of mendocino county. Farther ease, a cumulus
field was developing across the interior mountains. The clouds near
the redwood coast have been reinforced by a nice meso low that has
been seen spinning about 20 to 30 miles west of humboldt bay, with a
smaller meso low rotating around it (fujiwhara effect).

With little change in the synoptic pattern and the persistence the
stratus has shown the last few days, look for a repeat performance
the next couple of mornings. Sky cover was adjusted in the grids to
account for this, especially across the southwestern two-thirds of
mendocino county. Otherwise, as the upper ridge continues to
strengthen, heights aloft will continue to rise, with the net effect
being increased warming over the next few days. Highs will climb
into the 80s for the interior, with a few locations popping into the 90s. Lows at night will temperatures will continue to warm over the next few days, with warm temperatures likely across the interior, and seasonably warm readings near the coast. Some coastal river valley stratus will develop during the late night early morning hours through the weekend. Isolated thunderstorms may develop across the interior through much of the upcoming week, especially for trinity county. Be fairly pleasant for this time of year as well.

Long term
(Sunday through Friday)
a summer-like pattern will make an appearance for the end of the
holiday weekend and persist through much of the upcoming week. The
numerical models have come into better agreement with the overall
theme, which features a ridge axis to the east, with warm
temperatures and isolated convection developing across portions of
the interior. For Sunday and memorial day, the tail end of an upper-
level trough will begin to approach the region from the northwest. A
few vort maxes are seen in the data (especially the gfs) crossing
the region during peak heating Sunday and more so on Monday. This,
combined with a favorably southeast to south low-level flow, may
allow a few storms to develop across the interior as convective
temperatures are breached. The best chance of seeing a storm or two
would be east of an orleans - willow creek - covelo line. Soundings
show mid-level lapse rates a little above 7 deg. C km with a nearly
super-adiabatic low-level environment. Freezing levels near ten
thousand feet will make some hail a possibility if these storms
develop, with gusty winds also possible given the inverted-v
signature seen in the forecasts. Any storm will be slow moving
though given the weak wind fields throughout the column, with storms
likely being terrain anchored or outflow dominant.

Tuesday and Wednesday has become more interesting, as the GFS drops
the base of the trough across the outer waters now, with a low in
the base nearby. Strong vort maxes ejecting across the region ahead
of the low could aid in convective potential if this forecast
verifies. The ECMWF shows a similar, albeit weaker solution. In any
event, confidence in potential foci for convection has increased,
with increased spatial and temporal periods for such added to the
zones.

As the first trough upper energy dive southeast by Wednesday,
another trough looks to clip us as it passes by to the north, with
additional jet stream energy crossing our neck of the woods. Thus,
convective potential was extended for mainly trinity county through
the end of the week. Temperatures will cool some during this time
frame, as lowering heights aloft and increased cloud cover play a
role in modulating this. Pd

Aviation
The marine layer was fairly deep today and quite intrusive.

Clouds spread well into the inland coastal hills and valleys and
were fairly slow to burn off, especially in mendocino county. At
uki yesterday, clouds had scattered out by 12 noon, but overcast
conditions continued well past noonday with MVFR CIGS around 020
feet. Acv & cec air terminals were also entrenched under a blanket
of stratus once again. The MVFR overcast was enhanced by a couple of
well-defined eddys off the coast. A glimmer of sunshine appeared
around humboldt bay around midday as breezy conditions developed.

Guidance and persistence suggest that the marine layer will remain
definite, so a repeat of today's conditions expected through
Saturday morning. Taa

Marine
Broad weak low pressure will remain over the waters through
Saturday providing light winds and small short period seas. A
ridge offshore will build toward the coast on Sunday bringing a
return of light n-nw winds that will last through mid week.

Eka watches warnings advisories
Ca... None.

Northwest california coastal waters... None.
