Synopsis An upper level low over the northeastern pacific will move
into the oregon this evening. Showers will develop across western
washington this afternoon as moisture from this low approaches
the area. Conditions will become drier on Tuesday, with lingering
showers mainly confined to the cascades. Drier, warmer weather is
in store for the second half of the week, with a few showers
possible in the mountains.

Short term today through Wednesday Overall conditions are
primarily dry across much of the region early this morning, with
just a few spotty showers left in the cascades.

An upper level low will move into oregon this evening and bring
additional moisture to western washington as it approaches.

Showers will develop late this morning and persist into Tuesday.

Current model runs indicate that most of the lowlands could dry
out by late morning Tuesday. High temperatures will be slightly
below average today-in the upper 50s to low 60s. Highs on Tuesday
will be more seasonable-in the mid 60s.

A drying trend is likely starting Wednesday as washington resides
between an upper level ridge building over the northeastern
pacific and an upper level low over the interior west. Models
continue to hint at the possibility of some wrap- around moisture
making its way back into the region, so have maintained a chances
of pops for the mountains. Highs will be warmer- mostly in the
upper 60s-lower 70s across the region.

Long term Thursday through Sunday an upper level low will
linger over western us on Thursday, before lifting northeastward
towards the northern plains Thursday night. Have maintained
chances of pops across the cascades as moisture may work its way
back into washington. Temperatures will be in the low to mid 70s.

Models then indicate that a shortwave may pass through the area
on Friday, briefly brining slightly cooler highs and an increased
likelihood of showers to the mountains. Thereafter, a ridge may
build offshore and keep the area mainly dry. Temperatures could
warm into the upper 70s by Sunday. 14

Aviation Southerly flow aloft will turn more southeasterly by
late this afternoon as the next upper level low approaches the area.

Cigs are a mixed bag this early morning with obs along the coast and
the northern half of the area all reportingVFR conditions... However
the SW interior as well as the south puget sound area... Including
sea-tac... Are reporting MVFR conditions. The aforementioned incoming
system will bring showers back W wa by late this morning for most
locations... And as such should start to see CIGS drop into MVFR area-
wide during the mid morning hours. Showers will taper off late this
evening and tonight as the upper low plunges further south allowing
for CIGS to gradually rebound intoVFR conditions.

Ksea... Low level clouds in place over the terminal resulting in low
end MVFR conditions during the early morning. Will see some
improvement mid to late morning as CIGS lift some... But will remain
MVFR into the afternoon as showers move over the area. Cigs
improving toVFR tonight as showers taper off. Surface winds SW 5-10
kt. Smr

Marine Small craft advisory winds remain in the strait... But have
died off in the adjacent waters. As such... Will leave the SCA in the
strait going until its expiration for the am forecast... But will
take down SCA in N inland waters and admiralty inlet. An incoming
weather system will keep winds up over the coastal waters... But
models maintain that speeds look to fall short of of small craft
advisory criteria... And thus no additional headline concerns for the
morning issuance. Onshore flow expected to dominate from Tuesday
through the remainder of the week for advisory level winds over the
coastal waters and strait at times. Smr

Hydrology The daily hydrology discussion has ended until the
start of the next rainy season; it will only be updated as needed
until then.

Sew watches warnings advisories
Wa... None.

Pz... Small craft advisory until 5 am pdt early this morning for
admiralty inlet-central u.S. Waters strait of juan de fuca-
east entrance u.S. Waters strait of juan de fuca-northern
inland waters including the san juan islands.

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.
