Synopsis Rain will return to the area today, with a generally wet
pattern continuing through at least the middle of next week. A
few thunderstorms will be possible across the area on Saturday and
again on Monday.

Discussion Precipitation is returning to northwest california
this morning as an occluding frontal system approaches the coast.

Light to moderate rain will continue to spread across the area
over the course of the day, however the progressive nature of the
front should generally limit amounts to around an inch or less and
help to mitigate any hydro concerns. A brief period of gusty
southerly winds will also accompany the passage of the front today
along the coast and over exposed ridgetops. A more showery regime
will take hold tonight into Saturday as colder air filters into
the region with the arrival of an upper level trough. Steepening
mid level lapse rates and modest CAPE values around 200 j kg will
lead to the potential for a few thunderstorms on Saturday,
particularly across the northern half of the area. However, snow
levels remaining around 4000 feet should keep the small hail
threat relatively low with any stronger showers.

Shower activity will quickly taper off Saturday night as a
shortwave ridge temporarily moves overhead. This will yield
generally dry and pleasant conditions for Sunday, with the
potential for some patchy fog and frost Sunday morning. Another
system will then bring additional rain and another chance for
thunderstorms on Monday, with a broad upper level trough over the
eastern pacific keeping intermittent rain chances in the forecast
for much of the next week. Cb

Aviation A warm front will pass through shortly, followed
quickly by a cold front around midday into the early afternoon. A
period of light to moderate rain will push onshore and may become
briefly heavy ahead of and along the cold front, before abruptly
tapering off. Ceilings will start offVFR but will lower below
5000 ft and toward 3000 ft as the cold front approaches. Some
scattering of the lower clouds and even partial clearing may occur
in the wake of the front later this afternoon and this evening,
but lingering low-level moisture and onshore flow will likely
result in broken MVFR ceilings much of the time into tonight. An
upper-level trough will bring some scattered showers back to acv
and cec late tonight into Saturday morning, with even a rumble of
thunder possible. Southerly winds will increase this morning and
gust over 25 kt along portions of the coast and exposed terrain,
then ease abruptly in the wake of the cold front. Winds above 2000
to 3000 ft aloft will reach 40 to 50 kt through midday as well,
with llws possible. Aad

Marine Seas of 6 to 8 feet mostly comprised of a long period
swell around 17 seconds are beginning to build, as southerly winds
increase and add a short-period component to the overall sea
state. Winds are approaching 25 kt near CAPE mendocino and will
reach gale force briefly from around the CAPE northward across
the northern outer waters as a cold front approaches later this
morning. Steep waves will build to 7 to 10 ft, resulting in
combined seas of around 12 to 14 ft across most of the coastal
waters by midday. Winds will ease abruptly later this afternoon in
the wake of the front, and tend more westerly, and short-period
waves will steadily diminish. However, combined seas will remain
above 12 ft through Saturday night with a continuing westerly
swell. Winds will remain relatively light into Sunday, with
perhaps a brief period of below small craft advisory conditions on
Sunday before the next storm system approaches for Sunday night
and Monday. Aad
