Area Forecast Discussion
National Weather Service Seattle WA
826 PM PDT Sun Jun 20 2021

.UPDATE...The current forecast remains on track and no changes are
planned for this evening.

Pullin

&&

.PREV DISCUSSION... /issued 243 PM PDT Sun Jun 20 2021/

SYNOPSIS...Dry weather is expected for the week. An upper ridge
will bring warm weather on Monday. Expect cooler weather Tuesday
and Wednesday with stronger onshore flow. High pressure aloft
will then bring another warming trend for the end of the week.

SHORT TERM /TONIGHT THROUGH WEDNESDAY/...High pressure will bring
dry and warm weather across much of the region this week.

We'll see temperatures spike on Monday with most areas seeing the
80s with a few low 90s possible (especially in the SW Interior
and the Cascade valleys). For reference, the daily record high for
Sea-Tac is 89 in 1992 and a few other spots, like Olympia, will
be close to their records too. The surface flow remains onshore
and we will see a sharp temperature gradient along the coast (60s
at the beaches and 70s-80s a few miles inland).

The ridge will push east and inland Tuesday and Wednesday and an
onshore push will bring cooler conditions overall. We'll likely
see morning low clouds then afternoon sunbreaks with temps back
in the 60s-70s. 33

LONG TERM /THURSDAY THROUGH SUNDAY/...High pressure will then rebuild
over the region on Thursday and continue into next weekend for
more warm and dry weather. Temperatures will be ramping up each
day and likely peak on Saturday and Sunday. Expect highs in the
interior reaching the low to mid 90s. Overnight lows will be warm
too and in the 60s. It'll be cooler along the coast where NW
winds will keep the beaches in the 70s. Ensembles are showing
cooler conditions by Monday with a stronger onshore push. 33

AVIATION...Westerly to northwesterly flow aloft will remain over W
WA into Monday as an upper level ridge remains over the area. VFR
conditions present throughout the CWA and will persist for the bulk
of the remaining 24 hour period. The only exception will likely be
HQM, where IFR marine stratus is expected to redevelop tonight.
Surface winds remaining N thru the period under 10kts.

KSEA...VFR conditions for the entire TAF period. Winds N under 10kts.

18

MARINE...High pressure offshore with lower pressure east of the
Cascades will allow for enough of a gradient to continue low-end
small craft advisory level winds over the Outer Coastal Waters today
which may eventually work their way into portions of the Inner
Coastal Waters. Although this looks spotty, will leave inherited SCA
intact.

Onshore flow strengthens a bit by Tuesday. Small craft winds look to
persist over the Outer Coastal Waters, with higher-end small craft
level advisory winds likely (possibly even gales) over the Central &
Eastern Strait Monday and Tuesday evening/night. Model data remains
consistent on speeds hanging in the SCA range, but will allow for
another model run before pulling the trigger on any additional
headlines as this still remains third period. Thereafter, regular
diurnal pushes are likely down the Strait each evening through the
end of the week, with generally light winds over all other waters.

18

HYDROLOGY...The daily hydrology discussion has ended until the
start of the next rainy season; it will only be updated as needed
until then.
