.SYNOPSIS...
Strong high pressure builds over the region this
week, bringing unseasonably warm and dry conditions to western
Washington along with morning fog. A return to cooler and wet
conditions occurs over the weekend.

&&

.SHORT TERM /TODAY THROUGH FRIDAY/...
Strong high pressure remains in control for dry and mild
weather through the end of the week. Mid and high clouds are
streaming overhead but we will see decreasing clouds this
afternoon with conditions becoming clear. With the mild air mass
in place, max temperatures will track above average with highs
in the 50s to lower 60s through Friday. Overnight lows will be a
few degrees cooler with 30s around the south sound. 33

&&

.LONG TERM /FRIDAY NIGHT THROUGH TUESDAY/...
Wet and cooler weather returns over the weekend as the flow
aloft turns to more zonal. Snow levels will lower Sunday night
and Monday, around 3000 ft, with accumulating snowfall expected
in the mountains and passes. Precipitation, heavy at times in
the Olympics, will keep the Skokomish River in Mason County
running high with minor flooding possible. More lowland rain and
mountain snow moving through early next week due to a trough.

.AVIATION...
An upper ridge remains centered over the Great Basin today with
broad troughing offshore producing light southwest flow aloft over
Western Washington. Low level offshore flow continues. High level
moisture filtering through the ridge is expected to thin today with
continuing VFR conditions most areas into this afternoon. With
clearing skies today, greater coverage of LIFR fog and low clouds is
expected tonight for interior areas from central Puget Sound area
southward into the Chehalis Valley. Most areas are expected to clear
Thursday afternoon, though low clouds may linger much of the day
across the Southwest Interior.

KSEA...VFR today with thinning high clouds. NBM only shows 20%
probability of LIFR conditions Thursday AM, but the realistic
probability is more in the 60% to 70% range between 11Z and 18Z. VFR
expected again Thursday afternoon. Surface winds light and variable
today becoming N/NE 7 to 10 knots on Thursday morning.

&&

.MARINE...
SCA remains in effect for the coastal waters - primarily due to
seas through at least Thursday. Surface high pressure will
remain centered over the interior with a broad trough of low
pressure offshore producing varying degrees of offshore flow
across area waters. East winds may approach small craft advisory
levels at the west entrance to the strait and adjacent coastal
waters on Thursday. Active conditions well offshore will
continue to produce hazardous seas over the coastal waters this
week. A series of frontal systems will begin to reach area
waters this weekend into next week with the next best chance of
more widespread wind related headlines.

Dense fog will be a possibility over the inland waters through next
couple of mornings.

.HYDROLOGY...
Heavier precipitation over the weekend and early next week will
force rises on the Skokomish River in Mason County with the
river close to minor flood stage. Flooding is not expected
elsewhere over the next 7 days.
