Area Forecast Discussion
National Weather Service Seattle WA
845 PM PDT Fri Jul 9 2021

.UPDATE...No major updates needed to the forecast package this
evening-have only made minor tweaks to sky grids to account for
current observations of the marine stratus starting to push
inland along the coast and down the Strait of Juan de Fuca. Expect
stratus to continue to make its way inland overnight into portions
of the south and central Sound. Clouds will scatter through the
morning and retreat back to the coast by midday for another sunny
afternoon across the interior on Saturday. The previous
discussion follows below, with some minor updates made to the
aviation and marine sections. 14

&&

.SYNOPSIS...Weak high pressure aloft with low level onshore flow
will prevail into the first part of next week for dry weather and
temperatures a little above normal. An upper trough will cool
temperatures back to near normal in the middle of next week.

&&

.SHORT TERM /TONIGHT THROUGH MONDAY/...Dry weather will continue
with high pressure aloft and low level onshore flow. Onshore flow
will not be very strong with low clouds only pushing partially
inland each night and burning back to the coast by midday each
day. Highs will be a few degrees above normal each day. Schneider

.LONG TERM /TUESDAY THROUGH FRIDAY/...A broad upper ridge will
remain over the area on Tuesday. This looks like the warmest day
of next week as 850 MB temperatures peak over the area. Low level
onshore flow will continue but highs should still be in the lower
to mid 80s for the interior away from the water.

Gradual cooling will occur Wednesday and Thursday as the upper
ridge is replaced by a broad upper trough. It still looks dry but
onshore flow will increase for more night and morning clouds.
Highs will return to near normal.

Friday should be more of the same - a broad upper trough over the
area with decent low level onshore flow for night and morning
clouds with afternoon sunshine and highs near normal. Very typical
summer weather. The EPS (European Ensemble) continues to show a
few members with some very light QPF towards the end of next
week so there is a small chance the current dry streak could end.
Schneider

&&

.AVIATION...Upper level ridge over the area with southwesterly flow
aloft. Onshore flow continuing in the lower levels.

VFR conditions in place over much of W WA this evening although some
stratus right on the coast may result in periodic MVFR to IFR
conditions. These stratus will move inland overnight but for the
most part staying west of Puget Sound. In the Southwest Interior the
stratus will get just east of I-5 before retreating to off the coast
again by 19z. For locations east of the Sound, VFR conditions will
persist.

KSEA...Mostly clear skies. Northwest winds 6 to 10 knots becoming
light southwesterly 12z-15z Saturday. Northerly winds again
Saturday afternoon. Felton/18

&&

.MARINE...Varying degrees of onshore flow for the next week over
the waters. Small craft advisory westerlies in the evening and
early morning hours for the Central and Eastern Strait of Juan de
Fuca each day into early next week. Gale force winds are possible in
the Central and Eastern Strait Saturday night but will wait for 00Z
data to come in before determining whether a watch will be needed.
As such, no additional headlines planned for evening update.
Felton/18

&&

.SEW WATCHES/WARNINGS/ADVISORIES...
WA...None.
PZ...Small Craft Advisory until 5 AM PDT Saturday for Central U.S.
     Waters Strait Of Juan De Fuca-East Entrance U.S. Waters
     Strait Of Juan De Fuca.
