Area Forecast Discussion
National Weather Service Seattle WA
848 PM PDT Sat Aug 14 2021

.SYNOPSIS...A return to onshore flow will bring more seasonable
temperatures. A passing upper level trough will bring a chance
for showers over the northern half of the area Monday. High
pressure is expected to build again over the region by the middle
of next week.

&&

.SHORT TERM /TONIGHT THROUGH TUESDAY/...Forecast remains on track
this evening with marine stratus already pushing well into the
Strait of Juan de Fuca and into the coastal gaps. Expect plenty of
stratus to push into the interior portions area overnight. Remainder
of the previous discussion remains valid and follows below.

Onshore flow will continue on Sunday and we'll likely see similar
conditions with morning stratus clouds and afternoon sunbreaks.
Highs will be in the 60s and 70s at the coast with 80s in the
interior once again. A weak front will cross the area on Monday
for an increase in clouds, cooler temps (60s and 70s) and a chance
of showers. Showers will linger into Monday evening with a
convergence zone forming near the King/Snohomish line.

Tuesday will be mild and seasonal with near-average temps. We may
see a few showers over the north Cascades as a trough moves down
from B.C. and into eastern WA. 33

.LONG TERM /WEDNESDAY THROUGH SATURDAY/...A strong upper level
ridge over the NE Pacific will keep western WA under dry/north
flow toward the middle and end of next week. Low level onshore
flow will prevail, meaning areas of low clouds/marine stratus
along the coast. Temperatures in the interior will trend above
normal with highs in the 80s once again. 33

&&

.AVIATION...An upper ridge will continue to weaken over the area
tonight and Sunday with westerly flow aloft and low level onshore
flow. Stronger onshore flow will bring a return of low marine
stratus into most of the lowlands overnight through early Sunday.
Expect clouds to retreat to the coast with most terminals
returning to VFR by early afternoon, though clearing is less
certain along the coast. Elevated smoke will continue across the
area tonight then decrease from the west on Sunday.

KSEA...Some high clouds and elevated smoke continue this evening
and overnight. Expect low IFR stratus to reach the terminal by 12z
through the morning hours before scattering and clearing toward
midday. Southwest wind 3-5 kt through morning, increasing to 7-9
kt Sunday afternoon. 12

&&

.MARINE...Onshore flow will bring small craft advisory strength
west winds to the Central Strait of Juan de Fuca and East Entrance
the next couple of days, mainly during the nighttime hours.
Isolated gales are possible both Sunday and Monday evenings.

A weak front will enter the coastal waters late Sunday and then
fall apart as it pushes inland into Monday. Stronger northerly
winds return to the coastal waters toward midweek with high
pressure returning offshore. It's possible that winds approach
advisory thresholds over the outer coastal waters zones Monday
night into Tuesday. Seas will also build and remain choppy toward
midweek, with some potential for reaching 8 to 10 ft by Wednesday.

&&

.FIRE WEATHER...Marine layer clouds will push into the interior
lowlands of Western Washington tonight--they'll be deeper, more
extensive and take a little while to burn back to the coast on
Sunday. There will be even more moisture Sunday night into Monday as
the last gasp of a weakening front is added to the low level
moisture. With much higher humidity and lower temps there will be
a respite from fire weather concerns for a few days. It is likely to
warm up again around the end of next week. 19

&&

.SEW WATCHES/WARNINGS/ADVISORIES...
WA...None.
PZ...Small Craft Advisory until 3 AM PDT Sunday for Central U.S.
     Waters Strait Of Juan De Fuca-East Entrance U.S. Waters
     Strait Of Juan De Fuca.
