Synopsis Mostly dry conditions with the exception of a few
isolated showers this evening. More widespread showers are
expected overnight and tomorrow morning, with continued scattered
showers in places much of the day Wednesday. Widespread moderate
rain is expected again Friday into early Saturday, with dry
conditions the remainder of the weekend. More rain is likely next
week.

Discussion A frontal boundary is approaching the area. This may
bring a few showers to the inland areas this evening. There is
also a slight chance for thunderstorms this evening, but
confidence is low on this. Shower coverage will increase later
tonight. These showers will continue through the day on Wednesday.

Snow levels will remain over 5,000 feet. Rainfall amounts are
generally expected to be less than a quarter of an inch. There is
an outside chance of thunderstorms Wednesday afternoon, but
instability looked too weak to add thunder to the forecast.

Wednesday night models are now slower with the trough moving
through and out of there area. This is a complicated but weak flow
pattern. Small shortwaves will moving through the flow will
impact when the showers are heavier and lighter and the timing of
this is difficult to pin down. Thursday afternoon it looks like
there will be some showers, at least over the interior areas.

Thursday a brief period of high pressure is expected to build into
the area. This should help diminish showers Thursday afternoon.

This will be shortlived however, the next system will spread
clouds across the area Thursday night brining rain on Friday. The
current operational models have the rain coming in fairly early
Friday morning, but the general model consensus has it coming in
mid morning so confidence is low on the exact timing. Rainfall
with this system is expected to range from a half inch to an inch.

Snow levels will remain above 4,500 feet with this event as well.

Saturday the rain is expected to come to an end as high pressure
starts to build into the area. Saturday it looks like showers will
redevelop over the interior in the afternoon. The models are
showing some instability, but it looks like the better instability
is in the morning and will not coincide with the peak heating of
the day. Sunday there is better agreement that there will be
clear skies and dry conditions across the area. Frost is possible
in the morning, although confidence is low on how widespread it
will be.

Sunday into Monday the next frontal boundary starts to impact the
area. The models are still struggling with the exact timing of
this front. The operational GFS is one of the fastest solutions
bringing rain in Sunday. There is general agreement in the
ensembles that something in the neighborhood of 1 to 2 inches is
expected with the heaviest rain Monday or Monday night. Currently
snow levels are expected to be over 4,500 feet. Mkk

Aviation East to southeast winds ahead of the front have
lifted ceilings across the area and conditions areVFR. A few
showers are possible this evening over the inland areas. Later
tonight as this frontal boundary slowly moves north and east
showers will spread across the area. This may bring down CIGS and
vis slightly. Confidence is low on the timing of these showers.

Mkk

Marine A long period westerly swell has been a bit slow to
arrive today, but will continue to build through tonight and hold
through Thursday. Another larger west swell is expected to replace
it by Friday afternoon and continue through the weekend. Locally,
short period southerly seas are expected to rise tomorrow morning in
response to accelerating southerly winds driven by a system moving
northward along the coast. More short period southerly seas are
expected later in the week as well as another front moves over the
region, however confidence on the timing of this is currently low.

Relatively calm winds are expected tonight before southerlies
accelerate along the coast south of CAPE mendocino as a system
moves northward along the coast. These winds will be short-lived
but dynamic, accelerating and decelerating quickly as low moves
north along the coast. After these calm winds are expected to stay
light and southerly before another front approaches the coast on
Friday. Tdj
