Synopsis High pressure aloft will maintain cool but dry weather
through Tuesday. Areas of night and morning fog or freezing fog will
give way to afternoon sunshine. A series of weather systems will
bring wet weather beginning about Wednesday and continuing through
the holiday weekend.

Short term A sharp upper ridge will slowly move across washington
today through Tuesday. Skies will be clear today and Monday, with
areas of night and morning fog and freezing fog. Temperatures at 2
am were mostly in the 30s, with some lower 40s and upper 20s. Under
clear skies temperatures are several degrees lower than last night
at this time. Highs today will be in the lower 50s, and on Monday
they will be a few degrees warmer. Overnight lows will be around
freezing tonight and Monday night. The mountains will remain clear,
with the freezing level around 10,000 feet.

By Tuesday the upper ridge axis will be over idaho, and southerly
flow aloft will develop over washington as a front moves toward the
state. Clouds will increase during the day. Rain will probably reach
the coast Tuesday evening, then spread to the olympic peninsula
later Tuesday night. Highs Tuesday will be in the mid 50s. Lows
Tuesday night will be above freezing, mostly 35-40. Burke

Long term 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 Light northwest flow aloft continues over western
washington this morning as an upper ridge axis remains over the
coastal waters. The air mass is dry and stable with low level
offshore flow. Except for patchy low clouds on the north side of the
olympics and a little river valley fog this morning,VFR conditions
are expected today. The upper ridge axis will shift over the region
tonight with the flow aloft becoming southwesterly on Monday. A
surface ridge east of the cascades will weaken today and tonight.

This will weaken the offshore flow somewhat and allow stronger
nighttime inversions to develop. As a result, more widespread
coverage of fog is expected on Monday morning... Especially over the
southwest interior and south sound.

Ksea...VFR today. Surface winds n-ne 5 to 10 knots. May see some fog
develop in the vicinity of the terminal after 10z Monday morning,
but confidence in details not high at this time. 27

Marine High pressure over idaho with lower pressure over the
coastal waters will result in easterly (offshore) flow through
Tuesday. A weakening frontal system will bring the possibility of
gale force winds to parts of the coastal waters (beyond 10 nm) on
Wednesday. The cold front will probably dissipate as it moves
onshore late Wednesday. A stronger system is expected to impact the
area on Thursday for the possibility of widespread gale force winds.

Hydrology River flooding is unlikely over the next seven days.

Sew watches warnings advisories
Wa... None.

Pz... None.

It is not checked for accuracy either by anyone at L-36.com or by the source which is typically the US Government. See the NOAA web site for their disclaimer. 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.
