Synopsis A warm front will clip the area today followed by a
cold front tonight. Large waves will impact the coast on
Thursday. Thursday and Friday will be showery with an upper trough
over the area. A front will reach the area late Saturday. An
upper ridge may build around next Tuesday for a drying trend.

Short term A frontal system will move through the area today
with a warm front this morning and cold front this afternoon and
evening. The warm front is currently lifting north through the
area for a little light rain. There will likely be a dry period
of a few hours behind the front later this morning and early this
afternoon before rain from the cold front spreads inland.

The aforementioned cold front will push through the area early this
evening with rain turning to showers tonight. Showery weather
will continue Thursday and Friday with a broad upper trough over
the region. Most of the showers will become confined to the coast
and mountains by Friday however.

It should become windy today coast and northwest interior as the
frontal system moves through. Wind advisories are in effect. The
mountains should pick up some snow later tonight and Thursday as
snow levels come down. It looks like borderline advisory amounts
for now. Schneider

Long term Previous discussion... A wetter frontal system is
slated for late Saturday night into Sunday. Snow levels will
remain low, near 2,000 feet, for more snow in the mountains. A
weak ridge may bring drier weather Monday night and Tuesday. A
series of fronts will then keep the weather unsettled around
midweek. 33

Aviation Some areas of rain with a warm front will move
through the area this morning. A vigorous cold front will reach
the coast this afternoon and move through the i-5 corridor late
this afternoon and evening. Southwest flow aloft. Ceilings will
drop as the heavier rain with the main cold front moves ashore
later today.

Ksea... Rain will increase with a cold front later this afternoon
and evening--and breezy SE wind will develop with that front.

Marine A deep low far to the northwest will create strong
southeasterly pressure gradients over area waters for the next
several days. A warm front is brushing the area this morning and a
vigorous cold front over the coastal waters will move through the
inland waters early this evening. Gale warnings are up for the
coastal waters and northern waters east entrance, and gales are
possible again Friday and Saturday, especially on the coast.

Strong southwest winds offshore will generate large swell that will
reach the washington coast Thursday. Models have been consistent in
bringing swells of 25-30 ft to the coast, with even larger swells
offshore. Seas have not reached 30 ft at buoy 41 since december
2015. A coastal flood watch is in effect for the coast. This sort of
coastal flooding mainly affects the beaches as waves run far up
beyond where they usually do. Coastal towns such as ocean shores
and westport could see waves crash over breakwaters and sea water
could collect in low areas.

Hydrology A wet frontal system moving onshore around Saturday
night could push the skokomish river in mason county above flood
stage Sunday. Otherwise, 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.
