Synopsis A front will approach the area today and move through
western washington tonight into Friday morning. An upper level
ridge will build offshore giving the area dry weather over the
weekend. Frontal systems will brush by the area Monday and Tuesday
before a weakening front finally makes it into western washington
on Wednesday.

Short term today through Saturday Satellite imagery shows
cloudy skies over western washington early this morning. Doppler
radar has light rain along the coast and from about the
king snohomish county line northward. With the cloud cover
temperatures were in a narrow range, upper 40s to mid 50s.

Frontal system offshore early this morning will have a hard time
moving inland today with the parent low associated with the front
moving northward into the alaska panhandle. This will lift the
front north as well. In addition, the west northwesterly flow
aloft will result in a rain shadow for the central puget sound.

Will lower the pops from seattle south today down to chance but
keep likely pops for very light rain over the northern portion of
the area. With the front lifting north western washington will be
in the warm sector. Lots of cloud cover from seattle north will
prevent temperatures from warming up much this afternoon but south
of seattle with some breaks in the cloud cover expect highs to
warm into the mid 60s with highs near 70 possible in lewis
county. North of seattle expect highs near 60.

Front makes some eastward progress tonight with the front moving
through western washington early Friday morning. Steady rain will
develop ahead of the front tonight and continue until frontal
passage. Lows tonight will be in the upper 40s to mid 50s.

Post frontal showers later Friday morning with showers continuing
into the afternoon hours as an upper level trough moves into the
area. Convergence zone developing over snohomish county by
afternoon. Highs on Friday mostly in the 50s.

Upper level trough dissipating over western washington quickly
Friday evening. Flow aloft becoming northwesterly which could push
the convergence zone down into the metro area before the zone
falls apart Friday evening. With some breaks in the cloud cover
overnight lows over the southwest interior will drop into the mid
and upper 30s. Lows in the 40s for most of the rest of the area.

Upper level ridge building offshore on Saturday with the surface
gradients becoming northwesterly. This combination will dry out
the lower levels of the air mass. Light flow early in the day will
keep some morning cloud cover around but by afternoon plenty of
sunshine expected across western washington with highs in the
upper 50s and 60s.

Long term Sunday through Wednesday Extended models in good
agreement with a flat upper level ridge over the area on easter
Sunday for another dry and sunny day. Highs will be mostly in the
60s.

Models also in good agreement in slowing down the system that was
timed into the area on Monday. Want to see a few more model runs
before totally drying out the forecast for Monday. Will go drier
Sunday night and lower the pops into the chance category on
Monday. Highs will be in the upper 50s to mid 60s.

Model solutions for Tuesday and Wednesday having some
consistency issues with the strength and timing of the next front.

The GFS is stronger, wetter and faster than the ECMWF solution.

Both models have the front moving over the top of an upper level
ridge. With the model inconsistencies on timing and the ridge in
the vicinity will just go with a broad brush chance pops forecast
for Tuesday and Wednesday. Highs mostly near 60. Felton

Aviation A frontal system will move through the area today and
tonight with west to southwest flow aloft. The air mass is moist
and stable.

Ceilings are mostly 4000-6000 feet early this morning. Ceilings
will gradually lower during the day today but much of the
interior will likely stayVFR until late afternoon or evening.

MVFR low clouds with pockets of ifr are expected tonight.

Ksea... Ceilings 4000-6000 feet most of today with the terminal
somewhat rain-shadowed in westerly flow aloft. Ceilings should
lower tonight as the front pushes through. Southerly wind 5-10
knots. Schneider

Marine A frontal system will move through the area today and
tonight with onshore flow developing behind the front on Friday.

Gale force west winds are looking less likely in the strait
Friday evening but there is still a small chance. Onshore flow
will continue Saturday and Sunday. A second frontal system will
reach the area on Monday. Schneider

Hydrology Rivers coming out of the north and central cascades
will rise later today through Friday but remain well below flood
stage. River flooding not expected across the area for the next 7
days. Felton

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.
