Synopsis The weather pattern will be more active over the next
week as a series of fronts move through the area. The next one,
stronger than the front Sunday evening, will arrive on Tuesday.

An upper trough and onshore flow will keep the weather cool and
showery Tuesday night into Wednesday. Additional vigorous frontal
systems will affect the region through the rest of the week into
next weekend.

Short term An active weather pattern will bring periods of
heavy rain and mountain snow, gusty south winds and possible river
flooding this week (mainly the skokomish). The first front pushed
through last night with 5-12 inches of new snow in the cascades.

We'll continue to see scattered showers across the region today as
the cool upper level trough crosses.

A stronger and wetter pacific frontal system will impact the area
tonight through Tuesday. This system will bring heavy snow to the
west slopes of the cascades with 1-3 feet of new snow expected.

The orographics look better with this system due to strong
westerly upslope flow combined with wet conditions. We'll also see
some gusty winds with this system, especially along the coast and
north interior with south winds 20-35 mph with gusts to 45-50 mph.

Heavy snow will continue to affect the cascades through Tuesday
night as this system slowly exits.

We'll see a brief break in the action on Wednesday, in between
systems. Then late Wednesday night and Thursday, another strong
and wet pacific system will arrive. Models are trending wetter
with this system and advertising a period of heavy rain along the
coast and in the olympics. By then we may see river flooding on
the skokomish as it will be running high. The cascades will see
another round of possible heavy snow, especially during the
morning as snow levels will remains low (around 3,000 feet). 33

Long term Our active weather pattern will continue through the
end of the week with our third strong system arriving on Friday.

The main impact will be heavy mountain snow again as this system
will be cooler. We may see windy conditions along the coast and
north interior too. An upper level ridge will bring a lull on
Saturday. Then more rain and mountain snow on Sunday with an upper
level trough. Looking further ahead, the door remains open as
additional frontal systems roll through western washington. 33

Aviation Upper trough axis over the region this morning with
westerly flow aloft. The air mass is moist and stable. Moderate
northwest flow aloft developing later today as a weak shortwave
ridge moves across the area. Widespread MVFR and pockets of ifr
ceilings this morning will gradually lift toward midday becomingVFR
this afternoon. High and mid level moisture associated with the next
frontal system will begin to spread across the area late this
afternoon and evening. MVFR ceilings in rain will develop along the
coast around 08z tonight and spread into the puget sound area around
12z Tuesday morning. Increasing low level east-southeast flow ahead
of a warm front on Tuesday morning will lead to gusty surface winds
especially coastal areas and the north interior of western
washington.

Ksea... MVFR ceilings at times through 18z... Then lifting toVFR from
early afternoon through this evening. Ceilings lowering again
tonight ahead of a stronger frontal system... Becoming MVFR by around
12z Tuesday in rain. Winds at 5000 feet will be SW near 50 knots by
daybreak Tuesday. Surface winds southerly less than 10 knots through
this evening... Then shifting to SE and rising to 10 to 20 knots
early Tuesday morning. 27

Marine A series of fronts will bring southerly gales as times
to the coastal waters, entrances to the strait, and northern
inland waters.

Today will be a relative lull in the active weather with the
headline being for some 10 foot west swell over the coastal
waters.

Next front to reach the area will bring another round of gales
tonight into early Tuesday afternoon. After a break on Wednesday
the next front will reach the area Wednesday night and Thursday
with another round of gales likely in the usual spots. This system
is expected to hang up across the area into Friday with a surface
low eventually moving onshore. Models are in better agreement this
morning taking the low center to the north of the area Friday
which will result in another round of possible gales and at least
small craft advisory winds over most of the waters. Felton

Hydrology A series of fronts will cross the area over the next
week, bringing a period of rain roughly every other day. The
cumulative effect could be enough to push the skokomish river in
mason county to near flood stage by late this week. The best
chance for flooding on the skokomish is probably Thursday or
Friday when a frontal system could hang up over the area. The
hanging up over the frontal system late in the week also brings
up the possibility of flooding on other rivers flowing out of the
olympics.

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.
