area forecast discussion
national weather service seattle wa
755 pm pdt Wed may 22 2019

Synopsis The weather will be dry into Thursday except for a
chance of afternoon and evening showers and thunderstorms over the
mountains. An upper low will bring a chance of showers to the area
on Friday and another upper low might drop down over the area on
Saturday. Weak high pressure will be in place early next week.

Short term tonight through Saturday Some mid level
cloudiness continues to drift across the interior of western
washington in north-northeast flow aloft around a broad trough
digging southward over southern california this evening.

Shower activity has all but abated over the olympic mountains and
remaining showers over the cascades should diminish by or shortly
after sunset. No lightning strikes noted thus far.

Stratus continues to hug the coast in modest onshore low level
flow. The oth-sea gradient looks strong enough to pull the
stratus inland to at least the seattle area by daybreak
Thursday. A forecast update was made to account for some additional
cloud cover across parts of the interior this evening and overnight.

Otherwise, no changes necessary at this time. Looks like a mild
night ahead with stratus burning back to near the coast by mid or
late morning Thursday with another round of above normal
temperatures for the interior. 27
from previous discussion... Once again, there will be a chance of a
few showers in the cascades for the afternoon and evening hours--and
maybe a thunderstorm near the cascade crest. Highs will warm up a
bit more into Thursday. For Friday and Saturday showers return to
the forecast as upper troughs drop down through the area. The ecmwf
shows a chance for some wet weather Saturday afternoon and evening
around the puget sound area but the GFS is weaker and just shows
some scattered shower activity. High temps Friday and Saturday will
be cool with highs in the lower to mid 60s.

Long term Sunday through Wednesday From previous
discussion... The weather pattern next week looks unremarkable--we
will probably areas of morning low clouds but otherwise there is a
good chance for sunny days with temps a bit above normal. Highs
should range from the 60s on the coast with lower to mid 70s for the
interior of western washington.

Aviation Northerly flow aloft will continue tonight and
Thursday with an upper ridge offshore and an upper low over the
intermountain west. At the surface, onshore flow will continue
with high pressure offshore and lower pressure inland. The air
mass is generally stable except unstable over the cascades through
this evening.

Areas of mid level clouds from puget sound eastward should
decrease tonight. Low clouds near the coast the will spread
partially inland tonight then burn back to the coast later
Thursday.

Ksea... Areas of mid level clouds should decrease tonight. Low
clouds at the coast will spread inland tonight and probably reach
the terminal for a few hours Thursday morning. Northwest to north
wind 5-10 knots will becoming light tonight then west to
northwest Thursday afternoon. Schneider

Marine Onshore flow will increase on Thursday then gradually
decrease Friday and Saturday. Small craft advisory strength west
winds are likely each evening for the central and east entrance
strait of juan de fuca. Onshore flow will peak Thursday evening
when gale force west winds are possible in the strait and small
craft advisory westerly winds will bleed into the adjacent inland
waters.

There will be a brief period of offshore flow Saturday night and
Sunday with a thermal trough along the coast. Onshore flow will
increase again on Monday.

In addition, strong high pressure well offshore will bring small
craft advisory strength northwest winds to the coastal waters for
the next few days - initially over the offshore waters but
eventually spreading into the inner waters around Thursday night.

There will also be 10-14 foot west to northwest swell over the
coastal waters, highest farther offshore. Schneider

Hydrology The daily hydrology discussion has ended until the
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.
