area forecast discussion
national weather service seattle wa
916 am pdt Thu may 23 2019

Update The forecast is in good shape this morning with no
changes necessary. Visible satellite imagery does show an
expansive area of marine stratus extending along the coast, thru
the strait of juan de fuca and across the southwest interior into
portions of the south sound. This is simply a product of onshore
flow as usual as higher pressure sits offshore and lower pressure
remains inland. Given abundant sunshine today along with the
shallow nature of the cloud cover, the stratus should burn off by
early afternoon. Those that are not experiencing low clouds this
morning have enjoyed mostly sunny skies.

Overall weather conditions will be benign today, especially across
the lowlands under mostly sunny skies with high temps in the mid-
upper 70s. There will still exist the chance for a few diurnally-
driven showers and isolated thunderstorms across the cascades and
olympics this afternoon and evening. The main hazards from
thunderstorms will be gusty winds and locally heavy downpours. Activity
should then diminish a few hours after sunset.

The next shortwave is expected to drop down from british columbia
on Friday. This still looks to spread a better chance for
scattered showers to all of western washington. Best instability
for thunderstorm activity appears to remain confined to the
cascade crest and eastern slopes outside of the CWA during the
afternoon and evening.

Previous discussion can be referenced below with updated marine
and aviation sections.

Synopsis Afternoon evening showers and thunderstorms over the
mountains again today. A system will bring more widespread showers
to the area Friday into Saturday. Drier conditions possible next
week though the chance for mountain showers may continue.

Short term today through Saturday Marine stratus has made a
push into the southwest interior and down the strait early this
morning with ceilings between 300 and 500 feet. Oth-sea gradient
has relaxed slightly overnight but some patchy stratus may make it
close to the metro area by daybreak. Should erode back to near
the coast by mid or late morning. Otherwise fairly mild overnight
temperatures and plenty of sunshine should result in a few degrees
of warming from Wednesday's highs. Showers and isolated
thunderstorms will pop up in the mountains later this afternoon
and evening with marginal instability. Like yesterday, activity
shouldn't be super widespread.

Upper level trough will drop south from bc on Friday, bringing
the chance for more widespread showers. Amounts look to be fairly
light. This will serve to cool temperatures back into the 60s for
the start of the weekend. Fairly new over the past few model runs,
solutions show a secondary low dropping SE along the coast
Saturday which may bring additional showers. Have hedged forecast
in this direction though don't expect it to be a washout. Ceo

Long term Sunday through Wednesday Aforementioned low drops
south of the region on Sunday with high pressure returning into
mid-week. This should bring dry weather to most, though diurnal
showers possible over the mountains each day. Afternoon highs will
warm back into the 70s, except for along the coast which will be
in the upper 60s. Ceo

Aviation Low level marine stratus pushed into the interior
this morning with tops around 1400 ft. Low clouds will burn back
to the coast this afternoon. Showers and isolated thunderstorms
will develop over the cascades this afternoon and evening. Low
clouds will redevelop overnight with onshore flow. 33
ksea... Low clouds and fog at the terminal through 18z, thenVFR.

MVFR CIGS likely late tonight. S SW winds at the surface. 33

Marine Onshore flow will increase tonight with small craft
advisories in effect for the coastal waters and the strait of juan
de fuca. Strong northwest flow will develop over the outer coastal
waters on Friday with gales possible. Winds will ease on Saturday
and become light on Sunday. Onshore flow will increase again on
Monday. 33

start of the next rainy season; it will only be updated as needed
until then.

Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data. Changes in harbors due to building or dredging change tides and currents and for that reason many of the locations presented are no longer supported by newer data bases. For example, there is very little tidal current data in newer data bases so current data is likely wrong to some extent. This data is NOT FOR NAVIGATION. See the XTide disclaimer for details. In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
