.SYNOPSIS...A high pressure ridge will build inland Thursday
through Saturday, bringing dry and warmer conditions. Wet
conditions are on track to return by the end of the weekend and
into early next week as troughing returns.

&&

.SHORT TERM /TONIGHT THROUGH SATURDAY/...Onshore flow prevails
across western WA today with a broad trough across the West.
Showers have been scattered over the region but will fade out this
evening as an upper level disturbance exits east. Temperatures
will be chilly overnight and in the 30s for most areas, with temps
near freezing around the south sound.

We`re under dry, N flow, on Thursday as a ridge builds offshore.
Expect more sunshine and slightly warmer temperatures with highs
in the mid 50s.

High pressure shifts inland through Saturday for dry and mild
conditions. Morning lows will stay chilly and in the 30s.
Afternoon highs will reach the 60s to lower 70s with plenty of
sunshine. 33

.LONG TERM /SUNDAY THROUGH WEDNESDAY/...High pressure will shift
eastward on Sunday as a trough moves in from the west. Clouds will
increase through the day with rain, from the next incoming
system, reaching the coast during the afternoon. Expect one last
dry day in the interior with highs in the lower to mid 60s.
Precipitation spreads farther inland Sunday night as the cold
front moves in. We`re under moist, westerly flow, through early
next week for more rain and locally windy weather. 33

.AVIATION...Northerly flow aloft as a offshore ridge nudges closer
to western Washington. Mostly VFR for all terminals this afternoon
with the exception of PAE, where lingering convergence and showers
are keeping conditions at MVFR. Showers will continue to dissipate
throughout the afternoon, allowing VFR to persist at all
terminals. West to southwesterly winds look to turn more
northwesterly around 00-03z, and will generally remain light. VFR
will continue through the overnight hours. There is a 30-40% of
MVFR low clouds/fog to develop Thursday morning due to lingering
moisture in the lower levels. Otherwise, VFR will prevail through
Thursday as the aforementioned upper ridge moves over our region.

KSEA...VFR this afternoon as showers have tapered at the
terminal. SW winds this afternoon 4 to 8 knots may turn
northwesterly generally around 02z-04z. Latest guidance shows
winds then switching back to a more southerly component
throughout the rest of the overnight and into Thursday morning,
maintaining the same speeds. VFR will likely continue through the
TAF period, but there is a 35% chance of low MVFR clouds to
develop early Thursday morning.

.MARINE...Surface high pressure will continue to build offshore,
easing marine winds and seas through the rest of the week. Benign
conditions will continue through the weekend, before a frontal
system approaches the waters Sunday evening. Here, we will likely see
elevated winds and seas return to the coastal waters.

Combined seas 5 to 7 feet this afternoon will start to taper down
to 3 to 5 feet through the rest of the week and into the weekend.
Seas will start to gradually build upwards by Sunday ranging from
9 to 12 feet.
