Synopsis Rain will increase tonight and Sunday as a warm front
reaches the area. The trailing cold front will stall over the
region on Monday. A strengthening low center will pass across
the area on Tuesday, and a strong cold front will bring wind and
heavy mountain snow. Lingering showers will continue Wednesday
morning, then an upper ridge will bring dry weather on Thursday
and Friday.

Short term Rain will increase tonight into Sunday as a warm
front reaches the area. The trailing cold front will then stall
over the region Sunday night into Monday with strong, moist,
westerly flow over the area. The main impact is possible heavy
snow in the mountains, especially the north and central cascades
between mount baker and stevens pass. A winter weather advisory is
in effect from Sunday afternoon through Monday morning. Snow
levels are tricky and may waver between 4,000 and 5,000 feet with
generally 3 to 11" expected. Snow levels will then lower to around
3,500 feet early Monday. Snoqualmie pass should see mainly rain or
a rain snow mix.

In the lowlands, cloudy and rain at times Sunday through Monday.

Total rainfall amounts will range from 1" along the coast to
0.50-1.00" in the interior. Temperatures will mainly stick in the
40s for both highs and lows, with a few low 50s possible both
Sunday and Monday afternoon.

A stronger and wetter pacific frontal system will impact the area
on Tuesday. Heavy snow is possible in the mountains and snow
levels will be lower - dropping to around 2,000 to 3,000 feet
Tuesday night. It'll be windy too, especially with the frontal
passage Tuesday afternoon. However, the models keep waffling on
the low strength and tracking. For now it just looks like a
blustery front and winds are below wind advisory criteria.

Showers will taper off Tuesday night as this system exits. 33

Long term Another pattern change will take place on Wednesday
as a strong upper level ridge builds over the NE pacific. This
gives western washington dry, northerly flow which will help scour
out the low clouds and moisture. At this time, the ridge is
dominant through the extended forecast with dry weather through
at least christmas day. With a drier air mass in place, expect low
temps in the 20s to lower 30s with highs in the lower 40s. 33

Aviation Notice, pwt (the bremerton faa observation will
be missing through Monday due to electrical work. We will maintain
the TAF as best we can with no amendments.

Moderate southwesterly tonight as a warm front reaches the area,
becoming westerly on Sunday. The air mass is stable and moist at all
levels. Steady rainfall will arrive at the coast with the warm
front by early evening, with rain spreading inland the rest of the
evening. Widespread MVFR is likely as rain develops. Some local ifr
cigs below 1,000 ft and vis possibly below 3sm is possible,
especially at pwt and olm.

Ksea... MVFR 1000-1800 feet will like prevail by 00-01z through
tonight. Rain develops by late evening. Southerly wind 4-8 knots,
become south-southwest 10-14 kt W gusts 24 kt Sunday. Dtm

Marine Small craft winds expected all waters except the central
and western strait as a warm front moves across the area. Winds will
ease later Sunday.

Monday will be a lull in between weather systems. A vigorous
frontal system will move through the area Monday night and Tuesday
with gale force winds possible for the coastal waters. Offshore
flow will develop Wednesday. Dtm

Hydrology River flooding is not expected 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.
