Synopsis Showers will end this evening as an upper low moves
south of the area. Drier and warmer weather is expected most of
next week with afternoon and evening showers over the cascades
most days.

Short term tonight through Tuesday Water vapor satellite
imagery clearly tells the story this evening with drier air in the
mid and upper levels being imported on easterly flow aloft. The
upper level low that brought rainfall earlier today continues to
push southward off the central oregon coast. As of 02z, most shower
activity was south and west of the chehalis area. Surface gradients
will become northerly tonight, but they will be weak. Combined with
surface moisture from the recent rainfall, there should be some
redevelopment of low clouds overnight. It will scatter out
by mid morning Sunday. Heights will rise somewhat on Sunday and,
with partial sunshine, temperatures will rebound to close to normal
with highs in the mid 60s to lower 70s for much of the region. Some
instability over the mountains will contribute to showers and
afternoon thunderstorms with northeast flow aloft bringing some of
it into the foothills and, locally, the lowlands. 27
from previous discussion... The upper low will shift inland over the
southwest u.S. Sunday and Monday with an upper ridge off the coast.

Western washington will be on the northern periphery of the upper
low. There will be enough wrap around moisture and instability for a
chance of afternoon and evening showers and thunderstorms over the
cascades each day with the aid of daytime heating. The low lowlands
look mostly dry although a few showers could drift off the cascades.

A weak upper ridge will shift over the area on Tuesday but it
won't make much difference for the weather. It should be another
mostly sunny day. An isolated showers or thunderstorm could
bubble up over the cascades in the afternoon but the weak high
pressure aloft will probably cap things a bit.

Highs will warm several degrees on Sunday to slightly above
normal and then warm a few more degrees on Monday with lower to
mid 70s common. Highs will cool a few degrees on Tuesday due to
stronger low level onshore flow but remain a little above normal.

Schneider

Long term Wednesday through Saturday It looks like a
decidedly wishy-washy and uneventful pattern Wednesday through
Saturday with a weak upper ridge on Wednesday giving way to a weak
upper trough Thursday and beyond. There won't be any organized
weather systems but an isolated shower can't be ruled out at
times. Temperatures will be a few degrees above normal each day
with not much day to day variation. Schneider

Aviation Easterly flow aloft tonight as an upper level low slides
south of the area. Flow aloft becoming northeasterly on Sunday.

Light northerly flow at the surface has developed this evening as
weak surface ridging pushes southward over the interior of british
columbia. The mid and upper levels have dried considerably over the
past few hours, but lingering low level moisture from today's
rainfall should contribute to the development of some low MVFR and
ifr ceilings overnight. The low level moisture will scatter out by
18z Sunday. Daytime heating will contribute to some instability over
the cascades on Sunday with afternoon and evening showers and
thunderstorms possible. The flow aloft could bring some of this
activity locally into the foothills.

Ksea...VFR CIGS this evening lowering to low MVFR again at
times overnight. Confidence in the details between now and about 15z
are low. Surface gradients are light, but nights are short this time
of year. Some stratus development is possible. Surface wind light
becoming northerly less than 10 knots. 27

Marine Surface onshore flow will become light northerly tonight
into Sunday. Small craft advisory winds over the coastal waters
through this evening will ease to below 20 knots tonight. Flow will
be light on Sunday with increasing onshore flow Monday and
continuing through Wednesday. At least SCA level winds expected both
Monday and Tuesday evening in the central and eastern strait of juan
de fuca. Jd

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

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.
