.SYNOPSIS...
Cooler and unsettled conditions continue into Monday
as a series of systems crosses the region. A high pressure
ridge will build over the Pacific Northwest on Tuesday,
allowing for unseasonably warm and dry conditions with rounds of
morning fog and low stratus throughout the week.

&&

.UPDATE...Rain showers remain on track to taper back this
evening, with a brief pause before the next frontal system
moves through early Monday morning with more widespread rain.
All precipitation with this system will still wrap up by Monday
evening. Minor updates were made to the aviation and marine
section for recent thinking/updates to the rain impacts on
ceilings/visibilities.

.SHORT TERM /TONIGHT THROUGH TUESDAY NIGHT/...
Recent radar imagery shows post frontal showers across much of
the interior this afternoon. These showers will continue
throughout the evening dissipating overnight. High temperatures
this afternoon in the low to mid 50s. Snow levels around 5000
feet will keep the precipitation type as rain in most of the
Cascade Passes.

Another weather system will cross over western Washington late
tonight through Monday morning, with another round of rain
across the area. Winds will slightly increase in areas along the
coast and north of Everett, with wind gusts generally around
20-25 mph at times throughout the morning. Snow levels will once
again rise with the passage of this moist airmass, with levels
rising to 6000 feet. High temperatures remaining in the low 50s.

An upper level ridge will begin to build Monday into Tuesday for
a return to drier conditions across western Washington and
rounds of morning fog. Temperatures will warm up with afternoon
highs in the upper 50s, even some places seeing above 60.

&&

.LONG TERM /WEDNESDAY THROUGH SUNDAY/...
Ensembles are in general agreement with ridging over the area
throughout much of the week. Rounds of morning and nighttime fog
are likely with light offshore flow in the lower levels.
Temperatures continue to be well above normal with afternoon
highs in the upper 50s and even the lower 60s for some places.
Some model guidance hints ridging to move eastward on Friday,
allowing for some weak systems to enter the area by the weekend
for chances of precipitation.

.AVIATION...
Showers are lingering behind the cold front, with the
instability diminishing this evening post sunset. Cigs are
highly variable depending on rain coverage. Terminals under
these showers may experience periods of MVFR to IFR through the
evening. Elsewhere, expect MVFR and VFR. Given the limited
clearing this afternoon/evening, patchy fog overnight will
likely be limited and not dense. Probabilities for stratus are
higher compared to widespread fog. Another line of rain is
expected to move through Monday morning with variable
ceilings/visibilities lingering into the afternoon (trending
towards MVFR/IFR into the evening). Winds will remain out of the
south at 5-10 kt with a few gusts to 20 kt at times along the
coast and interior.

KSEA...MVFR trending towards VFR at the terminal this evening with
showers in the vicinity. Couple gusts to 20 kt remain possible
through late this evening, but will remain out of the south
through the TAF. With little clearing having been achieved so
far this afternoon, the TAF reflects a drop down to MVFR with
lower visibilities late tonight into early tomorrow morning due
to stratus and a more drizzle based pattern rather than fog.
Surface winds will continue out of the south through the TAF
period, with a few gusts to 20 kt late Monday.

.MARINE...
The cold front has moved off to the east, with showers
diminishing this evening. Winds will briefly ease this
afternoon before another system moves across the area tonight
into Monday. Winds will pick up once again in the same locations
as today, through winds look to be slightly stronger and more
widespread. SCAs for the coast have been extended into late
Monday night to account for seas remaining at 10-12 feet.

Afterwards, beginning Tuesday, broad high pressure builds across the
interior Pacific Northwest, forcing incoming systems to be deflected
and offshore flow will prevail across the area. Breezy winds may
persist across portions of the coastal waters Tuesday and Wednesday
as frontal systems encroach on the area but move off to the north,
tightening the pressure gradient across the area. Winds ease area-
wide by Thursday.

21/HPR

&&

.HYDROLOGY...
Skokomish River remaining elevated through Monday. A couple
of shots of rain over the South Slopes of the Olympics will
push the river up to near flood stage later today and again on
Monday. The flood watch for Mason county will remain in effect.
The Skokomish will begin receding significantly Tuesday with the
dry weather. No river flooding on the remainder of the rivers
in Western Washington for the next 7 days. Felton
