Synopsis A strong upper ridge will maintain dry and stagnant
conditions across western washington through Wednesday. The ridge
will break down by Thursday with rain returning Thursday night
and Friday. Wet weather will continue through the weekend with
strong moist flow over the area.

Short term An upper ridge will be over the pacific northwest
tonight and Monday for dry weather. An upper short wave will move
over the top of the ridge Monday night, temporarily flattening
the ridge. An associated weak front will reach the coast Monday
night then dissipate Tuesday morning. The main affect from the
Monday night system will be to bring some high clouds to the area
but there might be some sprinkles near the coast. The upper ridge
will rebound over the area Tuesday and Wednesday.

There are less high clouds than last night which should allow some
fog to form over the interior lowlands tonight. High clouds with
the next weak weather system will probably limit fog Monday night
but that will depend on how thick they are. Tuesday night should
see a big more fog again with less clouds cover. Stagnant air will
continue through Wednesday. A decision on whether to extend the
current air stagnation advisory will be made Monday. Schneider

Long term It looks like Thursday will be our last dry day of
this stretch as the ridge will start to break down. We should see
rain returning by Thursday night or Friday as a trough moves in
from the west. The models have been waffling on the exact timing
of this system and it's now slightly slower compared to
yesterday's (faster) solutions. Moist west to northwest flow will
continue trough the weekend for more wet weather with snow in the
mountains. 33

Aviation A strong upper level ridge axis will persist over
eastern washington through Monday evening, but it will flatten
some on Monday. A dissipating front will brush the coast on Monday
night. Light southerly flow aloft through Monday morning, becoming
moderate southwest on Monday afternoon and Monday night. The air
mass will be dry and very stable. Shallow dense fog will be the
main forecast challenge through Monday morning over the puget
sound lowlands. It will mainly favor sheltered valleys. In
contrast, dry east wind off the cascades will minimize fog over
king county. Looking ahead to Monday night, conditions for fog
development will be less favorable due to thicker cirrus and a
little more mixing in the boundary layer.

Ksea... Fog may settle into the valleys and over the waters near
the terminal later tonight, but the airfield is most likely to be
above it all, causing sea to remain free from fog with the help
of a light but drying e-se breeze later tonight. Monday will
feature clear skies and light south wind. Monday night appears
unfavorable for fog development at sea due to thicker cirrus and
better dry air entrainment into the surface layer. Haner

Marine A 1042 mb high over eastern washington and lower
pres offshore will result in moderate offshore flow through Monday
evening. A dissipating front will brush the north coast on Monday
night, causing easterly gradients to weaken. Light northerly
offshore flow will prevail on Tue and wed. Expect a cold or
occluded front to move across the area late Thursday night or
early Friday. This will cause the flow to become onshore and
strengthen.

Hydrology River flooding is not expected for the next 7 days.

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.
