Synopsis A weak upper level trough will pass mainly north of
the area tonight followed by a deeper trough that will shift
southward across the area Wednesday night into Thursday. This will
produce a chance of showers across the area... Especially in the
mountains Wednesday night and early Thursday. Weak high pressure
will build into the region Friday and early Saturday before another
trough settles over the region early next week.

Short term tonight through Friday As of 8 pm, satellite
imagery still indicates some cloud cover over central puget sound
and a few inland areas along the coast. Some drizzle has started
to develop across king and snohomish counties. Could see this
continue over the next few hours. Otherwise, expect cloud cover to
fill in across western washington overnight as a trough
approaches the region. May see some light precip develop up near
the canadian border by just after daybreak Wednesday with a better
chance for showers spreading southward as the day GOES on. Models
develop a convergence zone over the central puget sound Wednesday
evening then shift it into the cascades overnight. Most of the
shower activity should be in the mountains by Thursday morning as
the trough axis exits the area. Weak upper level ridging builds
into the region Thursday night into Friday..Giving the area a
break in the weather and a brief return to near normal
temperatures before another trough arrives for the weekend. 27 14

Long term Saturday through Tuesday From previous
discussion... Previously mentioned upper ridging lingers into
Saturday but flattens quickly as another upper trough digs
southward down the british columbia coast toward the region. The
gfs and euro diverge with the trough's path by early next
week... So this certainly comes into play with timing and placement
of precip. However... The longwave trough position looks to be
parked over the west coast nearly all of next week. Above average
precipitation and below normal temperatures are a safe bet as we
head into Monday and beyond. 27

Aviation A weak system will move by the north tonight. Onshore
flow will continue in the lower levels, while west northwesterly
flow will persist aloft through Wednesday. Conditions across the
terminals as of 830 pm range from MVFR toVFR-with terminals
along central puget sound never quite clearing from the cloud
cover today. Some drizzle has started to develop across portions
of the central sound. Could see this continue over the next few
hours. Otherwise, clouds will fill in this evening ahead of an
approaching upper level trough. Will see ceilings deteriorate
again late tonight and may see some light rain develop across the
northern interior by mid morning Wednesday.

Ksea... Current conditions MVFR. Ceilings will lower overnight as
a weak system moves to the north. Variable surface winds 5-10
knots will turn more southwesterly again this evening and will
increase to 10 to 15 knots overnight. 27 14

Marine High pressure over the coastal waters with lower
pressure inland will result in varying degrees of onshore flow
through the week. Gale force westerlies will continue in the
central and eastern strait of juan de fuca this evening into the
early morning hours on Wednesday. Small craft advisory winds will
likely bleed into admiralty inlet waters. Small craft winds are
also expected over the coastal waters through Wednesday and into
Thursday. Have issued a gale watch for the central and eastern
strait of juan de fuca for westerlies Wednesday afternoon and
evening. Otherwise, onshore flow will continue throughout the
week with small craft advisory winds in the central and eastern
strait possible each evening through Saturday. 27 14

Hydrology While big precipitation producing storms occurred last
fall and early winter, it has been much drier than normal since the
start of 2019. The warmer, dryer spring has left the area with
growing water supply issues. The snow pack was lower than normal in
may and has since mostly melted out already. Most western washington
rivers are running below normal with a handful having daily record
low flows. And for much of western washington, the water supply
forecasts are for below normal volumes, many in the 5 percentile
range of lower. Please see our drought information statement, water
supply outlook, and drought information webpage at:

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.
