Synopsis A frontal system will approach western washington
this afternoon and move inland during the afternoon and evening
hours. A series of systems will follow and make their way through
the region throughout the remainder of the week, keeping the
pattern wet and unsettled.

Short term today through Thursday Current satellite imagery
indicates mostly high clouds moving across western washington
early this morning. Cloud coverage will continue to increase
throughout the day today as a frontal system approaches the coast.

Expect the messy system to reach the coast by the late morning
hours and slowly move inland throughout the afternoon and evening.

Most locations should continue to see dry conditions for much of
the day today before the front starts to move eastward. Winds will
be breezy ahead of the system for areas across the northern
interior. Temperatures today will be near normal-mostly in the
upper 50s to low 60s across the region.

A secondary front will then pass through the region on Wednesday
afternoon and evening. This second front looks to be better
organized-so have maintained rain in the forecast for much of the
day on Wednesday. This second system will bring another, stronger
round of breezy to locally windy conditions to areas across the
northern interior and sound. Latest guidance continues to indicate
wind speeds that remain just short of wind advisory criteria, so
have held off on any headlines for now. However, this will
continue to be monitored with later model runs. Temperatures on
Wednesday will remain in the upper 50s to lower 60s.

Yet another system will pass through the region on Thursday,
brining additional rainfall and another shot of breezy winds
along portions of the sound. A slight chance of thunderstorms
along the coast can also not be ruled out. Temperatures will
start to cool slightly and are only expected to reach the mid
50s. 14

Long term Friday through Monday A wet and unsettled pattern
will continue throughout the extended time frame, as an upper
level low pressure system continues to remain situated over the
western canadian coast. High temperatures will cool a few degrees
and mostly be in the low to mid 50s. Overnight lows will primarily
be in the lower to mid 40s. 14
aviation... Southwesterly flow aloft increasing through tonight as
cold front slowly approaches the coast. In the lower levels flow
remaining offshore with front to the west.

Increasing high clouds over the area this morning with a mid
level deck arriving this afternoon. Rain beginning along the coast
midday with the rain pushing inland during the afternoon and
early evening hours. With the onset of the rain ceilings lowering
down into the 4500 to 6000 foot range over the interior with
ceilings remainingVFR into Wednesday morning. For the coast
ceilings lowering down into the 1000 to 2000 foot range with local
visibility 3-5sm in moderate rain.

Ksea... High cloud overcast this morning with a mid level deck
this afternoon. Ceilings lowering down to around 5000 feet 00z-03z
Wednesday and remaining near 5000 feet into Wednesday morning.

Light winds becoming southeast 4 to 8 knots this afternoon. Winds
increasing slightly overnight. Felton

Marine... A strong front will reach the coastal waters by
this afternoon and shift inland during the evening and overnight
hours. A gale warning is in effect for for the coastal waters and a
small craft advisory for the inland waters through Wednesday
afternoon. There is potential for gale force winds across portions
of the northern inland waters Wednesday afternoon as secondary front
moves through but will let day shift further assess. Have also
issued a small craft advisory for rough bar for grays harbor bar as
combined seas build to 10+ feet. Periods of blustery weather will
continue for the rest of the week as additional weather systems move
through the waters. Additional headlines will likely be needed. Seas
will also build along the coast to 15 to 20 foot range by
Thursday. Ceo

Hydrology A series of wet systems moving through the area
today into early next week will cause rivers to rise, but river
flooding is unlikely over the next seven 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.
