Synopsis High pressure aloft will maintain cool but dry weather
through Tuesday. Patchy night and morning fog or freezing fog will
give way to afternoon sunshine with high reaching into the low or
mid 50s. A series of weather systems will bring wet weather
beginning about Wednesday and continuing through the holiday weekend.

Short term A strong upper ridge will maintain the dry offshore
weather pattern through Monday. Southerly flow develops Tuesday with
the flow becoming onshore, although rain the next elongated front
will hold off until Wednesday when the ridge shifts further inland.

Low dew point air has infiltrated most of western washington due to
the northerly or offshore flow the last couple days. Dew points are
in the 20s across most the area while temperatures have dipped into
the 30s, and below freezing in colder pockets. Only a few prone
valley locations are reporting fog, while enough dry air has mixed
down to the surface, inhibiting fog formation elsewhere. Most the
area will have another mostly sunny day, and any morning fog will
dissipate over the next couple hours.

High pressure aloft and a relatively dry air mass, even near the
surface, will limit fog to patchy coverage Monday morning in prone
sheltered valleys. Clear skies and a dry air mass will again allow
for strong radiational cooling with lows down to the 30s, except mid
to upper 20s in colder valleys. Mercer

Long term Previous discussion... Wednesday through Saturday will
be a wet period. Rain will spread inland Wednesday, with likely or
better pops everywhere by afternoon. A front will move through
Wednesday night, and another one will arrive Thursday afternoon. An
upper trough will keep at least showers going on Friday. Models
differ about Saturday, with the euro fairly dry but the gfs
distinctly wet, so have kept likely pops Saturday.

Qpf is not especially heavy with these fast moving systems, with
perhaps an inch of water per day in the mountains and half that in
the lowlands. The wettest period currently looks to be 18z Thursday
to 18z Friday. The snow level will fall to 4000 feet on Wednesday,
and even lower by the weekend. This means there will be snow at
times at the ski areas and in the passes. Burke

Aviation High pressure and offshore flow will lead to dry and
stable conditions across western wa today and Monday. The flow aloft
is northerly with E NE winds at the surface. Skies are mostly clear
forVFR conditions. Low clouds an or fog may be more widespread
Monday morning with less mixing. 33
ksea...VFR today with N NE wind to 10 kt. 33

Marine Offshore flow will prevail across western wa through
early this week due to strong high pressure east of the cascades.

Winds are N NE over the waters. The next frontal system will
approach the region on Tuesday then split and weaken as it moves
inland on Wednesday. A stronger pacific frontal system will impact
the area on Thursday with gales possible over the coastal waters.

Hydrology River flooding is unlikely over the next seven days.

Sew watches warnings advisories
Wa... None.

Pz... None.

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.
