Update Early signs of a developing convergence zone were
evident as of 10am this morning between mount vernon and everett.

This feature is likely to persist well into the afternoon hours
before diminishing this evening while very gradually drifting
south. Elsewhere scattered light showers were moving east across
the region and will gradually taper off from west to east this
afternoon and overnight. Showers may linger into the morning hours
over the north cascades and surrounding foothills. The forecast
has been updated to reflect the latest trends and short range
guidance. -wolcott-

Synopsis A frontal system will bring periods of light rain and
locally breezy winds to western washington today. A secondary front
will keep conditions wet Thursday and into Friday. Upper level
ridging is expected to resume over the weekend allowing for dry
conditions as well as overnight and morning fog. A front may
approach the region early next week with a chance of rain.

Short term Early signs of a developing convergence zone were
evident as of 10am this morning between mount vernon and everett.

This feature is likely to persist well into the afternoon hours
before diminishing this evening while very gradually drifting
south. Elsewhere scattered light showers were moving east across
the region and will gradually taper off from west to east this
afternoon and overnight. Showers may linger into the morning hours
over the north cascades and surrounding foothills.

Winds peaked across much of western wa earlier this morning and
have begun to decrease. See the marine section for additional
details. -wolcott-
from previous discussion:
models have also shifted the next system a bit further north which
would bring much less rainfall into the area. There will be a lull
between systems tonight, then light rain should develop Thursday.

At this point, the trend is for keeping the bulk of rainfall
across the far north. From around puget sound southward, pops were
cut and QPF lowered. The second system looks weaker than the one
over the area today, with only light rain amounts. The north
cascades could see an inch or two deepening on how closely the
next system passes to our north. Showers will linger into Friday
morning, but a drying trend should begin later in the day.

Long term A strong upper level ridge amplifies offshore Friday,
then shifts over the pacific northwest over the weekend. Models
keep the ridge in place through at least Monday, with areas of
night and morning fog. Cold pocket locations will drop below
freezing for lows, with freezing fog likely around the southwest
interior and interior south puget sound.

The gfs ECMWF continue to have difficulty establishing the long
wave pattern next week, although both models agree on split flow.

This will tend to slow and weaken systems as the northern branch
brings systems into the region. Timing of systems early next week
is difficult with models flip flopping with each run. The ecmwf
shows some light rain possible by Monday night or Tuesday. A more
active weather pattern could develop next week.

Mercer

Aviation A slow moving frontal boundary is moving across the
air this morning with moist air mass in place. MVFR conditions
generally are the rule this morning with a few sites bouncing
betweenVFR and MVFR in heavier showers. Precipitation will
decrease this afternoon, but given residual moisture in place, low
MVFR to ifr ceilings will persist tonight into Thursday morning.

Low level southerly flow will peak this morning as front moves
through, gradually subsiding through the rest of the period and
becoming weakly onshore Thursday. West southwest flow aloft will
transition to west northwest behind the front.

Ksea... Above discussion applies. Showers will become more spotty
this morning into early afternoon before tapering off. Moist
airmass in place will likely keep MVFR ceilings going through the
period. Possible could briefly deteriorate to ifr at some point
overnight but too low confidence for inclusion with morning taf
issuance. Winds easing to under 10 kts tonight. Ceo

Marine Cold front continues to push east southeast across the
area this morning. Strong low level winds continue with small
craft advisory conditions across all waters. Gradient will
gradually relax with subsiding winds later today into tonight.

Second system will move through later Thursday into Friday with
small craft advisory winds possible again for northern coastal
waters, west entrance to the strait and across the northern inland
waters by Thursday afternoon. Offshore winds return for the
weekend. Ceo

Hydrology The first system today will leave just relatively light
amounts of precipitation. So far there has been widespread one to
two tenths of an inch with up to 1 inch of precipitation in the
mountains. Not much of a response from rivers is expected. The front
will make its way through the area today with showers tapering off
late this morning. Will need to monitor rainfall for later this week
with the next system brushing the area Thursday, but amounts look
about the same as today . Flooding is unlikely on areas rivers
through the next 7 days. Jbb

Sew watches warnings advisories
Wa... None.

Pz... Small craft advisory until 3 pm pst this afternoon for admiralty
inlet-central u.S. Waters strait of juan de fuca-east
entrance u.S. Waters strait of juan de fuca-northern inland
waters including the san juan islands-puget sound and hood
canal.

In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
